Biggest problem: using FOSSIL (un)natural gas for anything! It is only a little less FILTHY than coal(!!) and WAY filthier than everything else (solar, hydro, nuke, wind, …) USA must get off the fossil madness! Using heat pump tech for heating houses and tap water is the future (actually it has been used fir decades in civilized places)! District heating is another option, circulating heated water from garbage, minimizing dirty landfills… cleaning the exhaust is of course necessary.

I had a lime coated tank that I replaced with a Renai. I love the tankless upgrade. No water softener needed. Every year or two, isolate the unit with the shutoff valves and use a small sump pump to run white vinegar through it to dissolve the lime. You will never need to replace it.

2009 I installed a tankless. It was great. I was out of town weekdays and only in on weekends. What a great savings. Always endless hot water with extra high usage on 2 days of the week.

Thanks a bunch Eric. We have a hotwater tank in our home for 15 years and now looking to get into a tankless unit soon.

By far the most instructional video I’ve seen explaining Tankless W/ Heater. I learned new things coming from family of plumbers. Keep on making this videos please .

Great content, great discussion. I'm a super fan of tankless and have installed it some pretty novel applications. Our current home will likely receive an upgrade to tankless when the current water heater moves on.

I have been using a tankless for the last 5 years.I love this thing. It is really neat the way you dial in the temp, and it stays at that temperature.

Thanks for the overview, and you make good points, but after owning a Noritz condensing unit for four years, I'm not a fan of tankless heaters. We renovated our house, which had two 40 gal tank heaters in parallel. Contractor's plumber convinced me to install a tankless Noritz to replace the two tanks ("instant hot water!"). I said I wanted to keep one of the tanks as a backup - in series, bypass-able, with thermometers on the inlet/outlet/return of the tandem arrangement so we could troubleshoot the loop if needed. Plumber said I wouldn't need it but agreed to install all the bypass valves and the thermometers I asked for because it was just extra income for him. The tank heater - 10 years old at this point, and still going strong -- has saved me from running out of hot water at least twice or three times each year when the tankless has failed (about 10 failures in total). More often the tankless doesn't fail entirely but errors-out on high exchanger temperature, requiring a bypass if you are showering, and a "wait and reboot" sequence. But with the failures, I've had to replace an air-gas mix valve, an air fan (the turbo charger you talk about), the water mix valve, a control panel, a PCB (printed circuit board), and my personal fun-in-the-hot-attic event: full heat exchanger replacement. I am so thankful that I kept to my guns with the spare tank as I would have been completely without hot water multiple times over the past few years until Noritz sent a part to me. And although Noritz has warranted parts, troubleshooting takes several hours of my time, and in the case of the exchanger replacement, expensive plumber's time. What you didn't mention in the water quality section is that tankless need to have much cleaner systems to operate. I clean my system each year with vinegar at minimum, or the solution when I feel like it. Our system is on relatively soft city water, but I have an inlet filter for both the city supply and the hot water return line. I do this solely to ensure the tankless doesn't foul (it did foul a few months after commissioning due to teflon in the line - that's when I installed the filters. Tanks, although they do collect sediment, are much, much more forgiving. Kirk

Costs are only comparable to replace a tank water heater with a tankless heater in a few circumstances. The tank water heater needs to be by a wall, if it sits out in the room next to the furnace then you will have to move the water heater location to a wall or have a wall built. Tankless water heaters cannot float in midair. If you are moving the water heater to an existing wall now you will need to rerun the water pipes, gas line, and flue to the new location. (All at additional cost compared to replacing a tank water heater with a tank water heater). All residential water heaters require a 1/2" gas line. Almost all (but like you said in the video a few don't) require a 3/4" gas line. So most tankless conversions require upgrading the gas line to the heater. (At an additional cost compared to a tank-to-tank replacement). All tank water heaters are vented with either the metal flue pipe along with the furnace (or with a power vent heater PVC). Less than 20% of tank water heaters currently installed in homes are power vent models. So, a tankless water heater requires a whole new vent system to be installed. (At an additional cost compared to a tank-to-tank replacement). I am not even mentioning the size of the job if the basement is finished and now you are cutting open drywall ceilings to run the vent pipes. Having the recirc feature set up on a tankless water heater diminishes the efficiency of the heater. Now the heater fires up (on the model you show in the video) a 200,000 BTU burner (that's bigger than most residential furnace burners) to heat and circulate the water to the sink. If you have a gravity feed recirc line to the tank water heater this is done continuously at no additional cost. I noticed that you don't tell people that with a tankless water heater you have no hot water during a power outage, but with a tank heater you still have all the hot water you normally do when power is on. You might have to shower by flashlight but it's hot water. It sounds like your tankless water heater costs you money in utility bills. Your daughters wouldn't be able to take super long showers if they didn't have unlimited hot water. Think of how much water you would save with 10-minute showers. You state that you charge pretty much the same to replace a tank water heater with another tank one or a tankless. In Nebraska the average flat rate for replacing a 50 gal. water heater with a like one is $2,000. A typical tankless water heater conversion runs about $6,000. A 50 gal. water heater is $700 and your model tankless runs $2,700. If you install tankless water heaters for $2,000, put me in your next open slot and come install a tankless at my house. If you charge $6,000 for a tank water heater installation, how do you sleep at night? The question I ask homeowners that are considering switching to a tankless water heater is, "do you run out of hot water on a regular basis?" (Like you, several daughters showering or a big soaker tub that is used regularly)? The main benefit of a tankless water heater is the ability to have unlimited hot water. But if you don't constantly run out of hot water this isn't a feature that is really needed. Even with the higher efficiency of a tankless compared to a tank type you will not see that significant of a decrease in the utility bill. The majority of the gas consumed a month is by the furnace not the water heater. Most likely you won't even recoup the additional cost of switching heaters after 20 years of a slightly lower utility bill.

If that's true, it might be very expensive, especially for someone who has to have it done by a contractor because for whatever reason the homeowner cannot do it his/her self.

All I have to say on this subject is that I highly suggest you get to know ALL the requirements of installing tankless way ahead of time. I learned the hard way that there is way more complexity to tankless than one might think. This was far from a simple swap in my case.

Same here. Where I'm at, gas isn't an option. We have three people in an apartment with a compact tank (looks to be about 30 or so gal). In the winter, when the incoming water supply is extremely cold, we have to time it so that there's a half hour or more in between each of us taking a shower, which means that we're having to get up way more early than we really should so that everyone can get ready. Plus, we each only get at most10 minutes of hot water, because as the incoming cold water replaces the outgoing hot water in the tank, it's mixing with it and lowering the temperature of the hot water still in the tank, so the "hot" water isn't really even lasting for the time that would be expected of 30 gallons at 2 gallons per minute. If we could replace it with a tankless, and everyone be able to take back-to-back showers (or even better, all at the same time, since we have multiple bathrooms), we'd all be able to get another hour or more of sleep.

This was an exact replacement for the old one that lasted about 10 years. kzread.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

Our replacement water heaters have been $150-$350 and our electric bills are not excessive. No one answer for everyone…there are a lot of variables like perhaps all copper insulated plumbing which holds the heat in the pipes when everyone is showering in the morning or the day I do laundry. As well…we have a water softener with a by-pass for the cold drinking water so it’s not salted.

A carbon filter will eliminate chlorine as well as filter out debris. Soft water will eliminate scale build up and a good water regulator will provide a consistent flow rate for accurate water flow adjustments. Water temperature is determined by the amount of time the water takes to pass through the water heater. If it takes to long, the water will overheat and the safety switch will prevent the gas from heating the water. Too fast, and the water won’t heat up to the desired temperature. My unit is designed for a flow rate of 2.5 gpm. I’m 78 years old and a former industrial piping designer. I installed my tankless water heater in the early eighties and have never flushed it yet and it is still going strong. That’s about 40 years ago. Still have the original bill of sale and instructions. My local plumber didn’t believe me till I showed him. He’s since changed his mind about tankless water heaters.

Great review. I have personally installed 8 so far in various rental properties we own. Best was mid pandemic AO Smith 240 160k BTU ($1500 complete) to replace the 80gall HW tank in a 7 unit apartment building. It has run flawlessly & I no longer receive calls from frustrated tenants about no hot water. I installed a Stieble 24 plus in our Scottsdale winter home ($875 complete) & the gas consumption (kitchen cooktop & HW tank were the only appliance on NG) went from $165 to $13/month. & that was for the month of June when outside temps were 100deg & the temp in the garage was 115-120deg where the old HW tank sat cooking itself on a medium heat setting. I installed 2 Steible 20plus units in a duplex to replace the old rusted electric HW tanks in a damp flooding prone basement crawl space. Both units were installed in the bathrooms of each unit ($800 each complete) & have run flawlessly for 2 years. NG was not at the street. Electric consumption reportedly dropped significancy. 8 years ago I also installed a Steible 24plus ($699 complete) at our all electric Lakehouse. Highest electric bill with a/c etc running was $71. In the same period, our Lakehouse neighbor went through 2 propane HW tanks at $2300 each time, he also had to drain them to winterize. He just broke down & went with a Steible 29plus. On our larger homes I do install recirc pumps & the annual vinegar flushing is the only PM. When/where necessary I simply winterize with RV Antifreeze. My BIL just had one installed for $7200, but at least he did eliminate 2 75gall HW tanks.

I live in Wisconsin and installed my rinnai tankless 2 years ago. It's awesome. Most issues are due to incorrect sizing, incorrect gas supply or maintenance. The larger units due require upgraded gas supply, and a plumber should be able to identify this. Although it's simple, look at your meter. You need a minimum 5psi supply for a high volume tankless. This also means you'll likely need a 3/4" supply to your water heater from a 1" main supply. This line should come before your furnace, which is probably on a 1/2" supply and probably requires less gas than your water heater.

I had a large Rannai tankless heater installed over 20 years ago. It has never failed - not once. It's still running like new and I've done very little maintenance on it.

I am glad this fellow mentioned the water quality. Too many times people get the wrong idea about "spring" water and its quality and clarity. All water no matter the source needs to be treated. Even then it can still be bad quality. For instance, where I live the county does treat the water but it is still pretty hard and scaley and it destroys coffee makers, especially the Keurig's.

We had a tankless for years and LOVED it. The old house we bought and live in now was built with tanks and it's expensive to change them given the electrical needs... but we'd do it again in a heartbeat. Tankless was GREAT for us.

true that, check the temp rise on the unit, ive seen 77degree temp rise. you might have to slow down the flow or increase the BTU to keep a nice hot shower going. I went to spain and there are alot of tankless there. I got my hot shower, but had to slow the flow down quite a bit.

And a regular water heater needs time to heat cold water. So as the hot water tank draws down the output temperature drops … so your “hot shower” is time limited with a tank after which the next person needs to wait for recovery time. Tankless no wait time for recovery so you can have 5 or more people shower one after another and you will not run out of hot water.

@@Davidjune1970 Actually there are ways around this. Any standard tank WH is only going to give you about 80%- 85% of its 'reserve' as the cold water comes in to replace the hot that was made....as was said, a lot depends on the temp of the cold water coming in. But say you have a standard tank 40 gal, gas WH. If you have the space, you can add a 50 gal electric to the system as your draw/reservoir tank. The electric tank is always being fed at least warm water from your gas WH and the amount of HW reservoir to draw on from the electric HW is upward of 90%. I've installed this setup in families with three teenagers/two adults and they all get to shower with plenty of hot water. You're not spending the typical $$ that an electric WH would use because the gas WH is doing most of the work..... it heats the cold water coming in and feeds the electric WH that has become your HW reservoir. It's therefore an easy job for the electric WH to bring your temps to whatever you set it at. And where this system really goes for cheap is when someone is getting rid of a newer electric WH to put in a tankless. I've gotten them for free!

Great video and great replies. I’ve always wanted to go tankless with my background living in singapore and Seoul SKorea… all unites we lived in had tankless. Well presented!

My brother had a tankless system installed in his last house, and he and his family loved it.

We had one for 17 years and it never failed. The only issue I wish you would cover is the unit not firing when you open a faucet slightly. When we would barely open a sink faucet to wash hands, wash something gentle, the water demand wasn’t enough to tell the unit to fire. Not a huge problem, but a problem nonetheless. Great video sir!

The activation of a tankless water heater is triggered by water pressure drop. If the faucet is not open sufficiently, the pressure drop will not be sufficient to activate the water heater. Today’s faucets may be a problem as well because they are a water saver design which does not allow sufficient flow rate to activate the water heater. You can overcome this problem by modifying the water restriction device. Open up the hole in the restrictor until you achieve a flow rate that will allow your water heater to activate.

I installed my own in 2015. Rheem was the only company at the time that would not void the warranty if it was installed by a non certified person. I have had zero issues. Make sure you use the right PVC to vent, mine had to be solid core, not foam core like big box stores usually carry.

This is a very good and accurate video.I installed my first gas tankless in 1976.All the local experts called me crazy with the usual facts .Or more acurate opinions.Fast foreward to 2020.I moved into a new home ,had to do extensive repairs.I removed the 40 gal conventional tank and had a Electric tankless installed..Not surprising all the usual comments even from the plumber.Well the same result.

I bought a Westinghouse gas tankless hot water heater that is perfect! Been the best water heater I have ever owned and will never go away from them.

Operating costs for the tankless are much lower for me. I live alone, and am frequently gone for several days at a time. Not paying to heat 40 or 60 gals of water that isn’t even being used is key. Still having unlimited hot water available when the whole family arrives for special occasions is perfect. I highly recommend the Renai. My first tankless lasted 10 years, but my tech said it wasn’t a quality one and replaced it with the Renai. Going on 8 years on this unit and no problems. Even the one that only lasted 10 years more than paid for itself in energy savings.

I love my Rinnai tankless. I do live in an area with hard water, but I installed a water softener to take care of that. I've now had it running for the last 5yrs without a single issue. I do flush the tankless once a year myself (very easy to do) with the flushing kit - takes about an hour. The main think I love about it is that I never ever run out of hot water! My biggest peeve with tank water heaters was the timing of showers. Most families shower approximately around the same time back to back .. and sure enough .. after 2 showers .. the 3rd person would be out of luck with luke warm water at best. Does not happen with tankless. I also live in a warm area and we are able to do 2 showers and the dishwasher (on hot) running at the same time - no loss in temperature (mostly in pressure - but that's not the tankless fault). Anyway, I highly recommend them.

I've built quit a few custom homes and never found the tankless heater was able to justify the added cost. Even over the life of both tanked and tankless heaters the savings from the tankless heater never made up for the difference in cost. The only reason for the difference in cost, in my opinion, is greed on the part of the tankless companies.

I lived in Spain in the 80s and tankless water heaters were everywhere. Our family of four would go threw about 5 gallons of butane every two weeks. We also had snow. Our water was always more than hot enough and we never had an issue.

I’ve been a plumber for 38 years and as soon as you said, this video is sponsored by A tankless manufacture I know exactly where this video was going to go. You are one heck of a salesman. Knowing what I know I would never install one of these. In Wisconsin they no longer allow us to sell them as an energy saving device rather we can only sell them as an endless source of hot water. They have so many problems. They have been a huge moneymaker for me. I wouldn’t sell one to my worst enemy. you never addressed the fact that most existing homes usually have to upgrade their gas service to supply enough gas for this unit. You also forgot to address the question about how many fixtures can run at one time. I’ve had several customers that have water heaters that shut down. When they use multiple fixtures at one time. It’s very common for water instantaneous heaters to go into lockout if you run too much hot water at the same time. You didn’t mention any of the maintenance that is constantly required. You also didn’t mention the fact that you have to have water treatment devices with tankless heaters it’s not a choice they will lime up and be useless if you don’t. So many partial truths

I’ve had a Rinnai unit in my house for over 16 years and I have not had any issues at all with it. I had it installed when we built the house so the installation was a little more expensive but well worth it. As mentioned in the video my 14 year old son takes 30 minute showers and he doesn’t know how lucky he is that dear ol’ mom and dad had a tankless water heater installed. If or when I need to install a new water heater I may check into a heat pump unit but if the technology isn’t what I am looking for I will be installing another Rinnai unit. The one thing I will say is that it does take about 45 seconds to get hot water to my kitchen faucet about half way across my small ranch home and it’s worse on the end of the house in the master bathroom since it is all the way on the opposite end of the house from where the water heater is. Area plumbers keep telling me that it isn’t worthwhile to install a recirculating pump but my wife would probably disagree on cold Wisconsin winter mornings when she is trying to get ready for work 😂

Great video. Thanks for sharing. I replaced my electric tank water heater a couple of years ago when the tank finally rusted through developing a leak with an "Ecosmart" tankless. Everything you stated about their advantages has been my experience. It did cost more for me to install than just replacing the tank heater with another tank heater. The unit I purchased is a 3 stage 40amps per stage electric tankless. I had to buy the wire, the breakers, and a small panel for the breakers because my 200 amp breaker panel was full. My old tank electric water heater was a single 30amp circuit (#10 wire), so I had to upgrade to #8 cables. I did all the work including the electrical upgrade myself. I installed a valve kit that allows me to backflush the water heater. I have yet to do that but need to at some point. I've got a small pump and will circulate vinegar through the heating elements from a bucket.

Ditto that. My house was built in 96. I am the third owner. As typical with cookie-cutter houses in my area, the breakers for the big stuff are all outside, and there is a small sub panel in the garage (which mine has the grounding and neutral tied together, tisk, risk, the inspector didn't catch that) which handles all the outlets and lights in the house. If course, the sub panel in the garage was only 60 amps and was full, less one half-inch opening. Basically, the builder NEVER thought anyone would want to upgrade beans! So since the had planned on adding a tankless someday (and an electric one is really the only option here), I knew I'd have to upgrade the sub. So using my electrical training (I had an electrical license at one time), I upgraded the garage panel to 200 amps, and used a new service entrance panel (to have the disconnect right there) and then I had room for the electric tankless, the circulation pump, a couple new circuits in the kitchen, and a second washer and dryer on the second floor (so the people who would occupy the four bedrooms upstairs would not have to take their clothes all the way downstairs to wash them, leaving the downstairs washer and dryer free for power towels, kitchen towels, and the maid's quarters... Perfect.

Thanks for the wonderful information. We are considering a tankless and this is a great help.

I just got a tankless, up from a 24 year old tank (god only knows how it lasted that long). The old one was not making hot water very quickly and it was not dispensing very quickly either. It was in my attic and I was *terrified* of a catastrophic failure. Having had the tankless for a couple of weeks now, I can tell you I love it. I genuinely am looking forward to the gas bill, because I'm pretty sure the CCF I was using right before the replacement is going to be 2-4 times what I'm using now.

Regarding price, the cheapest Gas tank water heaters are about $400, tankless about $900 for the cheapest ones, $500 is quite a bit cheaper

This will kill any bacteria present in the tank, Evan if the water is treated with chemicals by the municipality. My comment presupposes this has taken place.

We have a gas-fed tankless water heater and have noticed a couple issues with the technology. First, you must maintain a minimum hot water flow in order to keep the heater heating. If you’re using just a trickle, soon any hot water in the supply line gets replaced with cold, and then you have to go all out hot to flush the cold water out, and water gets wasted. Circulating pumps would help but then the water heater runs a lot more, decreasing its efficiency. Second issue is that if your electricity goes out the gas water heater won’t run, (unlike a tank water heater which doesn’t need electricity) unless you plug the tankless into a battery backup UPS…

I had a Rinnai water heater mounted on the outside of my house. It was rated at 8 gallons per minute. I never ran out of hot water. After 17-18 years, I had to replace it with a similar Rinnai model and again, it just keeps pumping out hot water. No regrets here.

As a home inspector, the only reason I recommended a tank water heater over a tankless is, in the event of an emergency situation, you still have 40-50 gallons of potable water as emergency back up with a tank water heater. This is especially important in earthquake prone areas. Otherwise I've noted very few issues with the tankless.

Thanks Eric, I think you oversimplified purchasing cost. It is NOT a myth that Tankless water heaters are more expensive than tank water heaters (initially). From what I saw the cost lies more in the plumbing. I got two similar quotes last year to install a tankless water heater (including parts, labor, plumbing) and they were nearly $10,000, whereas a tank water heater was about $4,000. The tankless heater did cost more, but there was a huge additional cost due to the ""complicated plumbing"" of these types of water heaters. With that being said, the tankless water heater I looked at had a life expectancy of about 20 years, whereas tank water heaters have a life expectancy of about 10 years. After calculating how much I would save in gas because of the efficiency of the tankless heater, and having to replace my tank water heater after 10 years, I determined that I would start saving money after 12 years if I went with a tankless heater. I didn't chose a tankless because I don't plan to stay in my house for more than five years and it doesn't contribute enough to my property value to offset the cost. But, if someone is financially able to tie-up $10,000 and plans to stay their house for more than 12 years then it makes sense to get a tankless water heater. (At least from my own calculations and experience.) Note: The tank water heater was 40 gallon and the tankless was "its equivalent". Both were base models. Hope this helps those looking at this video.

Most houses will have many other options with a shorter ROI. Still, your prices are for new construction. (Or you're getting ripped off.)

Something would break on the unit, the repair guy would come out and he'd say "Yea, it's this thing, they don't make it anymore, can't fix it", and the homeowner was out $1K (or more) for a new unit. Even when some of these were under warranty the run-around was horrid. It's one of the horror stories that have kept us away from tankless, but I'm really leaning towards it, especially when natural gas costs are SKYROCKETING every winter (2022/2023 winter our natural gas costs more than tripled for 4 solid months). They are still near 1.5x what they were in 2021. Thankfully we have a High Efficiency water heater, but heating 50gal of water takes a bit of time for sure! If I go tankless, i want it to last a minimum of 15 years (that's what every tanked water heater I've owned has lasted, and I know people that are getting 20 out of them). Since I have power and gas to my existing unit, installation of a tankless should just require a mounting substrate put in, which honestly? That's 15 to 20 minutes extra work since all the venting already exists from my existing HE unit.

I can't believe the old one only lasted 22 years. Guess they don't make'm like they used to :). I am not HVAC, but a reitired RN and jack of all trades, ha ha. I first learned of tankless hot water systems while living New Zealand back in the '80s. Very popular. We had a Rinnia unit, not sure which model, and we also had another one gallon, (or 4 liter) capacity, electric wall mounted tank for "cuppa's of tea," both natural gas, in the kitchen (most businesses there had one of them in their breakrooms.) My plumber buddy helped me install the 1st one, back here in Kansas. It was all new to us and we probalby broke some code rules. We vented it out with triple walled, stainless steel, ducting into a three story brick chimney. But it lasted for 22 years safely. Like you, we never ran out of hot water, for showers, dishes, launday, and bathrooms, since. We raised 8 children and have all of the appliances that takes also. We do have a 50 gallon holding tank, that feeds the hotwater unit, from our 2009 geothermal heating/ac unit. Our Kansas public water is 58 degrees into the house. The the tankless unit call for water is delivered just under 70 degrees from the holding tank. That makes a great difference in temprature change especially in the winter when the geothermal is in its heating mode. MYTH MYTH MYTH. People just do not know. It is so neat you are out there to let them be aware. GOOD on you! I subscribed and I LIKE! Randy, Hay seed in Kansas and money in the bank from my savings in water power bills.

I changed my cold water heater from tanked to tankless 15 years ago. It was made by Bosch. The reason I chose Bosch was due to the fact that most of my power tools are Bosch and I appreciate the quality and longevity that they provide.

Had a Bosch dishwasher in my last home. Loved it. No room for one now, but I would buy another Bosch if I had the room.

I went tankless and wondered why I waited so long and why traditional tanks are still even made anymore. Flushing once a year is not difficult. Now if you are not mechanically incline or lazy then it is coming to cost you money. My brother bought a new construction home 15 years ago and tankless was the only option. His tankless is still going strong with just flushing it with vinegar every year. His neighbor didn’t maintain her’s and it died in 3 years. The key to owning tankless is yearly flush and routine maintenance.

Good advice on pre-treating the ground water. Did that before installing my on-demand heater about 8yrs ago. Put in a whole home system and change the filter every 2-3 months. Best thing about on-demand is you never, ever run out of hot water. Long relaxing showers!

We had a navien for 10yrs. Combo boiler/water heater. Worked great and saved us 3/4 on our gas bill. However 6 weeks after the 10yr warranty was up things started going. Motherboard, valves, other stuff. Our HVAC guy , a licenced navien repairman, was so frustrated along with us that after 8 weeks of trying various repairs we gave up. We replaced it with an american made lochinvar. Seems fine so far. We'll see after it's 15yr warranty is up.

One thing to keep in mind with tankless water heaters is to get one with a digital controller. The turn knobs are not good at fine tuning to get consistent temps between showers and sinks.

I had no problem adjusting the knob. I turned it once and noted how far it was turned and the temp difference which was 24 degrees. I wanted a 16 degree difference so I dialed back one third of the increase. So it took a total of two adjustments. Nothing hard about that.

When I did a tankless unit 12-15 years ago, the venting was VERY expensive as stainless steel was the only option. It looks like things have changed, but I understand where the concern came from.

Yes it has, so has the efficiency. I have a Rheem high efficiency unit that is good for roughly 6 gallons a minute and it’s vented via pvc pipe. You can hold your hand in front of the exhaust and it’s barely warm.

I've had the Rinnai in my house for more than 15 yrs. Our community has hard(ish) water (treated lake water), I've had the unit flushed twice, the solution was almost as clean as when I started. Never an issue with not enough hot water, able to fill my 4 person hot tube with hot water.

I bought my first tankless heater in 1980. They have been common in Europe for many years. I'm English. The second one I bought not only heated water but powered the central heating also. We use radiators in England. I love the fact that you can sit in the shower all day if you want. No tank to run out.

We have two tankless systems in our house. One gas in our main house and one electric in our in law suite. Both are Rinnai. Absolute best decision ever to go tankless and Rinnai has been incredible.

The point of on-demand is that there is zero consumption between uses,so you don’t have to re-heat the water all day and night to be prepared for use. So it is much more efficient than standard units. The calculation you need to personally make is how often you use hot water,the volume you use ,the initial cost of the unit and install,and how long they last. (And the energy cost of elec vs gas in your area) . The choice is individual.

Excellently presented! Thanks for sharing and the best of luck!

You covered a lot of good points for going tankless. There is one install cost that can be very expensive, and that is for the electric models. There are older homes in areas that don't have easy access to the power requirements these things call for. My parents had a handyman talk them into a having him install a tankless. When inquired to why the water was just luke warm, he said it was working just fine when he installed it. This is when I decided to start learning about tankless. The most important thing about the electric version is that they need a lot of amps to work properly. The unit that was installed was a smaller unit, but still required a lot more than a #12 wire on a 40 foot run. That's right, the handyman used the original cloth wrapped #12 to power this tankless that calls for #8 in a fraction of the distance. The framework design and flat roof of this house does not allow easy replacement of any wires to this breaker box. The cheaper option ($4,300) was to run power from the meter main to the heater with #6 along the outside of the house with a new disconnect. After that, the hot water was working great, no more fire hazard and I was able to sell the house.

The biggest cost for gas tankless water heaters is not the unit. It is the special vent pipe that is required. Unless you are fortunate enough to be able to mount on an exterior wall and vent directly through the wall to the outside, the pipe cost (including elbows, collars, and flashing) will run more than the gas unit itself. I speak from experience.

I've got the condensing style. I would never go back to a tank. But you must understand, there are trade offs. I did indeed have to upgrade my supply. I had an entire crew spend an entire day tearing up my yard, pulling in a new line, replacing my main regulator, and placing independent regulators on each of my appliances. The dual wall venting was expensive to me. Operationally, it works on a pressure differential. if the differential between the hot water request is not substantially greeter than the cold water request, No hot water will be produced. sometimes, I can be mid shower when demand for cold water is requested elsewhere in the house causing the differential to drop below demand requirements shutting down the heat exchanger and leaving me in a cold shower. Having to turn off the water and then turn the hot on full while i stand there naked and shivering waiting on the hot water to make it back through the pipes. Its a learning curve. I do like it better. But its NOT all unicorns and rainbows.It cost me a whole lot of money to get it all set up right after i hung it on my wall. And it is quite 'clunky' compared to the ol' reliable. But it is efficient and it never runs out. Oh yeah, it doesn't work if the power is out. so also be sure to install a UPS. That's another hondo. This is NOT one of Jack's "magic beans."

Well, that was a great sales pitch. When I recently choose to stay with my conventional tank style water heater, the deciding factor for me, which he didn't talk about, was the recommended preventive maintenance for tankless units. My old unit went 23 years using supply water with a high TDS reading requiring virtually no preventive maintenance. It probably would have lasted longer had I flushed it annually and replaced the anode but even 15 years like the one he cut into would have been enough for me avoid the labor-intensive tankless units.

I switched to tankless from electric after going through 2 electrics in 6yrs. The first had been in the house for 15yrs before I bought it and it died my second yr. The second one rotted out in 4yrs. My tankless has been in place 8yrs with no issues. I flush it every 2 yrs. It takes about 30min to do. Fortunately I work for a propane company so I can borrow the flush kit without having to pay a service call. You can buy the flush kit for about $150-200 or you can make one for cheaper money. All you need is a couple gallons of white vinegar to flush through the system. Not a lot of maintenance in my opinion! I have high iron content in my water, by the way, with no filtration!

I've built a few off grid homes and used tankless water heaters. With a gravity fed water system there was never enough pressure to allow the heater to even ignite and heat the water. A pressure pump is necessary to increase the pressure in order for the heater to work requiring more drain on the batteries.

I’ve had tankless now in two homes, one in the warm climate of the Deep South and another in the bitter cold climate of the north. We’ve never had an issue with a shortage of hot water as noted in the video. I would add only one suggestion, in my case I use an re-circulating pump external to the tankless water heater. It is a Taco brand and it has a feature where it learns your pattern of hot water use, so instead of always re-circulating it will learn for example when you normally shower in the morning and kick in before that time to have hot water available instantly.

The bad thing about my home,like Thousands of homes in Florida built in the 60s and 70s is the copper water lines are buried directly in the sandy soil under the slab. So I just checked my kitchen sink, it took one gallon of water before I got hot water. All the videos talk about the cir pump getting the water hot then shut it off, well that water under my sink might be hot for 6 or 8 minutes but if I wait just 2 minutes and use the hot water it’s already cold, the sandy soil just sucks the heat out.

Our biggest complaint about tankless has been the "luke warm" water you will get at a sink when turning the hot water on and off at a kitchen sink while handwashing dishes. The delay for the burners to kick on after it senses flow allows bands of cold water to exit the unit before the water is up to desired temp. This results in a luke warm output at the sink. Outside of that we love it and wouldn't consider going back. I have considered a loop to the heater from the kitchen sink that will run for a set time after flow is detected, just haven't done it yet.

In my kitchen it used to take 15 seconds and now it takes 25 seconds. So really it added only 10 seconds to get full hot water at 140 Fahrenheit for each location. It is very quiet and gained a lot of storage space. My model is the Navien 240

Good job Brother!!! Really just wanted to hear the efficiency ratings. But I watched ( and enjoyed ) the whole thing, thanks again...

Nice explanation. Nothing but tankless since the late 90s. Another benefit not mentioned here is that the water outlet temperature never fluctuates, which is noticeable on the smaller, forty gallon units most commonly available. When the old direct vent, Navistar/Bosch tankless unit finally failed a few years ago we got a new Rinnai from Ebay. Running a thirty plus foot exhaust line was a PIA but well the effort. Since my "helper's" father wrote the plumbing code for our state, we did everything by the book. Never had any problems, although the old unit could produce much hotter water, which was unnecessary.

Just went with a tankless water heater but I want to clarify one thing. This is later 2023 and the price of a good tank electric water heater was round $2,000 to $3,000 installed in my area. The gas tankless water heater we put in was a little over $6,000. So for us any type of ROI is basically shot, but we are hoping for a $15 year ROI, however time will tell. Our last water heater lasted 17+ years, and it is fronted by a water softener, so the hope is that this tankless will last at least 15 years. So the myth that tanks are less expensive is actually true, at least here in the Midwest. Again we went with a tankless for other reasons, but if cost is your number 1 concern, then you can save a ton of money initially by going with a tank.

re: Water quality: I have a hard water problem, and due to original construction constraints, I haven't been able to treat the water properly (still working on a solution). As a result, I've been flushing the water heater (Rinnai tankless, recirculating, condensing) with vinegar about every two to three months to mitigate the impact. The sentiment problem will impact any water heater, but since tankless heaters have no water tanks to trap sentiment, it's immediately flushed into the plumbing system, fouling fixtures, check valves, and anything else in the system. The solution I came up with is a spin down strainer at the EXIT of the water heater, which traps most sentiment, and can be flushed with the flip of a valve.. I believe installing these should be standard for tankless water heaters, i.e. it just makes sense, regardless of the water quality.

Circulation pumps may save some water, but are not cheap or energy efficient at all. If it comes with the pump then that is great. But for it to work you need water lines to go from the tank to the tap and back to the tank to create a loop. And the lines need to be insulated. And the pump runs constantly even when no one is at home. That all costs money.

No to everything that you said. Circulation pumps are a couple of hundred bucks and you need no extra lines. Technology has improved and the need for return lines is a thing of the past. My house is a little tech heavy and we use Amazon's Alexa Dots to do all kinds of things. You'll need the least expensive Dot that they make ($20) and a Tapo wireless switch. Get a 120 volt recirculation pump, install it, plug the Tapo into the closest receptical, and plug the pump into the switch. About 20 minutes before you want to use whatever hot water that is too far from the water heater, you tell Alexa to run the pump for 20 minutes. The pump runs for 20 minutes and then shuts off. You jump in the shower and the hot water is right there waiting for you. There will be some setup of all of your new devices but once it's done, you don't need to touch them again. I use the Dot/Tapo combination to turn lights on and off (and dim them if you have dimmable bulbs), turn on a small electric heater in my garage, run the pump, turn my garage exhaust fan on and off) and the Dot by itself to control our TVs.

Cool article - Thx ! -- Nice to see the mths put aside.

We've been using a tankless now for 5 years or so and this is my observation since switching. 1) we have a gas tankless. And I suspect a similar issue is involved with electric ones. But we had to get our gas meter replaced with a higher pressure/volume unit. And we had to have new gas regulators installed on all the existing gas appliances (stove and furnace) to compensate. Because we're dealing with a monopoly, it took weeks for them to come out and swap out our gas meter. It didn't cost us anything, but it was a pain anyway. For electric, I suspect we would have had to have a new circuit installed in our fuse panel and power lines run to the unit. 2) Cold water sandwiches. No, not the kind you eat. We have a condensing unit and periodically while taking a shower, the water will suddenly get "colder" for about 15 seconds, then it returns to the original temperature. Granted, it's not *COLD*, but it's cold enough to notice and you need to be aware of this so you don't compensate by making the water hotter, because when the hot water returns, it will be too hot! 3) It does take longer for the water at the faucet to feel hot. Not a lot, but it is noticeable. I've toyed around with a recirculating pump, but cost wise, it isn't worth it so we put up with it. 4) maintenance. Our tank heater we never bothered with maintaining it. And when it was taken out of the basement, it showed! gunk came pouring out and into the back yard! Yuck. So, one of the things I heard with tankless is that if you don't descale it yearly, it will become junk in less than 5 years. So I purchased a sump-pump some hoses and a bottle of chemicals and a bucket. And every year, I run the chemicals through the heat exchanger to keep the scale at bay. This $150 investment I hope will pay off in the long run. And it's just 20 minutes to do. Then when it's done, I write on the side of the tankless heater, the date of the descaling to keep track!

The problem is with clients wanting to switch over to electric tankless from electric tank water heaters. But in all cases so far, all the fuse panels would have had to be replaced. They just didn't have the space for the 2 or 3 extra 40 amp fuses, or they didn't have enough overall amperage and had to move up to a 200 or 300 amp box. Plus, lines have to be run, which gets expensive quick. I noticed he didn't mention that.

I installed one 18 years ago and after a year I replaced it with a tank heater because if you reduced the hot water in the shower it would often turn off the unit which left you with cold water unless you increased the hot water flow again. The incoming water in the summer time here is pretty warm so you need very little hot water. hopefully current models have a adjustment so you can control the pressure at which the unit turns off and on....

Not a problem on current tankless heaters.

Then you didn't have the correct unit for your application and low flow isn't an issue with current units

Why not just turn the cold water up ?

Most don't enjoy the cold water plugs between hot water usage. Search Cold Water Sandwiching on youtube

Very comprehensive presentation. Thank you.

I was using propane powered tankless heaters in Spain in 1964. They were cheap and worked very well. They have been used all over Europe for a very long time. I recently converted to natural gas her and heard the same myths when I enquired about tankless, especially the “our water is too cold here one”. They did install a larger meter because I expressed an interest.
