​@@Martin_HermannYour fridge is a heat pump. If you feel the air coming out of the vent (usually bottom front) it is warm air. That air was heated by pumping heat out of your fridge (via coils and a compressor). Pumping heat out of the fridge keeps it cold. Residential geothermal is the same idea, but the inside of the fridge is replaced by the ground.

I work for a Geothermal exclusive company in the NW Chicago area. We do the entire job start to finish. Vertical boring is what you do in a city...it is possible in most areas. 150ft/ton straight down. We bore 5" holes drop the pipe, grout with bentonite/graphite mix. Also we use methanol as an antifreeze and have protection to 15°F. Not possible on every city job. But many more than most people think.

Polypropylene, Polyethylene and 316L SS are preferred for high purity waters. You can use PVC and CPVC, but they are more prone to failure long term.

For example, try electrolysis on some lab grade ultra pure distilled water at a low voltage. It won't work because the water is a very good insulator.

One to pull the water out of, and service the water needs of our property, and the other well to dump the water back into. The problem we had was the pump drawing the water out of the main well, was always breaking down, and had to be serviced several times a year.

Used 300’ per ton as length of tubing. So ended up with 2 loops 6-8’ deep one goes out with pipe in bottom of trench leak tested and back filled with 2’ over that pipe, top pipe is 6’ deep for a total for 2.5 ton is 1000’ 3 ton unit has 1 continuous loop of 1000’ 8-10th deep. System was designed without additional electric heat for a backup. In 21 years have not needed it either, even at 10pm outside. Very happy with this system. Did not use anything but water with make up valve and expansion tank, no glycol at all. Pipes are in the attic which I run 2 pumps in winter 24/7 to prevent them from freezing, summer they run with compressors. Did all the work myself except for the digging, hired that for $1,000.00, and I tested for leaks and back filled myself. Would do it again except would use antifreeze with a back flow preventer.

Hey quick comment. In my experience, I've used 50/50 for non automotive use. As an automotive professional, I know that antifreeze/coolant also has lubricants, anti corrosion, anti organic life, on top of other additives. Diluting antifreeze may cause premature impeller and bearing wear, loss of anticorrosive properties, and affect the PH level allowing organic life to grow. Mind you this takes a really long time. Even though you may not need "antifreeze", I do recommend something like freezetone that offers such additives to continue protecting your system with superior conductive properties.

They can go deep with a closed loop system, if you have limited space. Instead of drilling two wells for an open loop, you drill one hole and place the heat sink loop in the hole. It may not be as efficient as placing that loop at one specific depth, but it's still way more efficient than air to air heat exchanges.

You can do something very similar on a boat in some areas. The water around the boat is typically cooler than the air in summer and warmer than the air in winter. If you can utilize this difference you are that much more efficient. Marine heat pumps have been around for years and my particular favorite is the MarineAir 16,000 btu 120 volt model. There are things you must do however. There must be an hull strainer and an in line raw water strainer before the water pump. The strainer and pump must be below the water level that’s outside of the hull. There must be a flow switch (not provided) to shut things down if there’s an obstruction. Loss of flow can be more catastrophic in winter because slow flowing water can freeze the water in the heat exchanger, rupture and flood the hull. Moisture alarms throughout a boat is always a good idea. A condensate pump to move water overboard is also required. It’s also preferable to have the heat pump unit above water level so when it cycles off some water runs backwards through the impeller pump and the two strainers help with backwashing and keeping things clear.

I built 12 years ago. Three zones with 6T of cooling. Four trenches 12 feet deep with 9,000 ft of 1" HDPE tube. Great system and very efficient. 29SEER Florida H.P. now Bosch.

We had GT done here in northern west Michigan of course it’s all sand they went at least 15 feet down on a closed loop works great we have filled our propane tank once in 4 years and we use most of propane in the fire place, we received two years of tax breaks and money from the electric cooperative, one of the best investment’s ever we also run on solar and have batteries.

An excellent rundown of what you did, good sir. I just found your channel and will most certainly be perusing the rest of your videos, especially the ones about actually building a working system, since I am currently looking at such a thing to complement the fully off-grid power system I am constructing for my own home.

My father's cousin installed a well type geothermal system in her yoga center in the late 1980's. I have had dreams of building a system exactly as you describe for several years now. Since I would build this into my existing hydronic heating system, my main investments would be in a water to water geothermal unit and a some small fan-coils with condensate drains to be used for hydronic cooling on a separate loop. I have a backhoe attachment for my tractor, keeping the trenching investment down to diesel and time like in your case. Thank you for the guidance on tax incentives - I was considering looking into that aspect and you gave me some good places to start. Nice work on your build and I am happy to see that you have had such a positive result!

I appreciate the kind words

Thanks for that Video I can add some points that you didn't mention. 1) you forgot to mention that not only the cold side of the heat pump makes a difference in cop but also the hot side. At first I would optimize at the inside. You showed pictures of ducts inside the house. I assume your heat pump creates warm air that is going to be distributed across your building. As you mentioned water is more eglibe for transfering heat, i would suggest to use that instead of air. normally at my home country you would run coils in the floor of your building, warming that. That way the heat pump only has to heat up the water to 95°F in winter time to keep your home warm. The pump that delivers the heat to the whole building eats up only about 10 - 30 Watts, what is sure less than a fan needs. Additionally in the rooms you won't have noise and air movement. 1b) We here also do some ducts but we run them only to exchange the used air against fresh air from outside so you need to open the windows less for air quality. This air is brought inside the building by a heat recovery exchanger to lessen the heat loss. 2) to decide if a ground heat source or outside air source is better it is important to knwo where you're at, how many hours per year it is going to be how cold. If you know that you can do the math and then decide the annual more - or less energy you need for either system 3) you also want to have your ground analysed to know if it is better or worse suitable for the geothermal system you describe before making descisions 4) There is no xxx feet of pipe is needed per ton. this is absolutely dependent on the kind of ground and the operating hours per year, and if you plan to use antifreeze in the system. There are people around who have software to simulate this. 5) Antifreeze: Normally you want to use 0% or 20 - 33% of antifreeze, if you use glycol. the glycol we get here contains anticorrosive elements. Therefore you better inform yourself and fill in the mixture that is mandated by the manufacturer. If you design your coil for usage with plain water and get into trouble you can always later change to antifreeze filling. Be aware that you will never design your coil to be sub zero celsius (freezing point of water), or you'll suffer of performance of your ground coil, or even destroy it as time goes by if you repeatingly freeze the ground around it. 6) If you need to cool the house in summer you can use the water of about soil temperature and send it to your pipes in the floor. that way you don't need any energy (apart from the two pumps) to cool down your house. If you are at a warmer region and that is not enough you can reverse your heat pump or have a air handler that is connected to the outside coil 7) if your garden is to small then use vertical drilled holes. they need to be quite long and this is nothing for DIY, as it requires special skills. the length and the amount of those borings need to be simulated, to ensure that you will be able to use them for the desired life span. in several hundred feet depth the heat is not really easy moved and if your vertical collector is to small you risk of cooling it down to an unusable temperature in 5 or 10 years. by the way: if you connect your AC to it and heat your heat source up in summer time it helps a lot, so you need smaller borings and get an almost infinite life span out of it. 8) water quality: I'm pleased somebody speaks about the water that is going to be filled in a circuit. yes, you can use destilled water, that's great. At my place we have special water softener resin cartridge that take out all of the salt (not to mistake for ion exchanger resin that can be regenerated with salt), what gives almost the same quality of water as destilled water. Advantage: you don't have to carry the water around but have a small cartridge you connect to your tap water. Cheaper? maybe not, depends. 9) about the layout of your trench: it is not always best to dig as low as possibe. The design of your collector needs to make as much as possible use of the ground between the collectors. If you speak a little bit of german or know how to use the translator then you can find tons of useful informations and another angle of sight how we're doing such things in europe. Assumed you understand metric units maybe you will find it interesting to read on some forums and company websites. try following words in google: grabenkollektor, ringgrabenkollektor, trenchplanner.

I love listening to your videos. I'm thinking about doing geothermal in my house barn and garage all-in-one. But I would like to do in floor resident. Thank you for addressing soil types. With your comment about rock I probably will have to use my pond.

Great video very informative. That being said I work for a company that treats these types of systems and there are a few things to keep in mind. Yes water is better at transferring heat but if you go below 18% glycol you will have sever bacterial growth in the system. This can rob it of efficiency while also causing maintenance issues. I wouldn't go below 30% with a glycol mix. Also if you are using a gycol mix it is extremely important that the water you mix it with is pure water whether that be distilled, DI or RO because regular water will form precipitates that can reek havoc on the system like the bacteria. I like the comment below me on using methanol although going with just water and keeping it moving would work too.

Worked at a Wastewater treatment facility, learned of buried tanks that leaking, were pulled out to learn why and where, and realized they were destroyed by thousands of tiny pinhole leaks caused by microbes in the ground. Maybe location matters. Apparently there are millions of yet unknown undiscovered microbes tearing up ocean liners too.

I think this makes sense in almost any climate but especially new builds in cold climates (along with going above code for insulation and air sealing).

Thank you, clear and concise, you eliminated all the mystery involved in G/T with your explanation, appears pretty simple, just labor intense.

I'm in the process now of power cables and driveway and I'm going to try to do my geothermal tubing in the ground at the same time. I plan on running mine to a well house where I'll have a storage tank where it will circulate the glycol water solution and then from there out to my greenhouse out to my house and whatever other little project I've got going.

A little over a decade ago, while living in PA, I had to replace our furnace and AC. I chose to go geothermal. The installer put in a vertical closed loop system with two wells to take advantage of the heat transfer properties of the water. My old furnace was propane fired and was really expensive to operate (over $600/mo in the cold season). After all the tax credits, the geothermal system ended up being $8500 more than a high end hybrid propane/heat pump system. This included installation of an 80 gallon hot water heater and 55 gallon buffer tank. I had estimated a return on investment of just over 3 years. It ends up, the gt heat pump was so efficient, I got my money back in just over 2 years. Winter heating costs dropped to less than $55/mo. Summer cooling dropped by more than $100, and I also got free hot water in the summer due to the buffer tank. And, because the system ran more frequently than my old one, it was way more comfortable. I really miss that system.

I installed a Fujitsu 12RL mini split heat . pump several years ago and am totally glad I did. 1 unit, centrally located in my 1900 sq ft ranch. I live in Maine and have wood as a back up. The unit produced useful heat at -15 F one winter - it is only rated to -10F by the manufacturer, I was told that is as cold as the testing equipment got. I usually burned 6-7 cords of wood a year, the installer said I would only need1/2 cord a year to supplement the few extreme cold days. I could hardly believe him but he was right on the money. I burned 1/2 cord a year for several years, and last year burned no wood at all. Essentially, a good heat pump is roughly cheaper than any heat source but wood, and about the same as wood but without the labor and mess of wood, which is considerable. I got the heat pump because I was getting older and the wood was not getting easier. I am totally happy with the result. The coldest part of the year I would burn 1 cord a month, at $200/cord. The heat pump costs, during the coldest months, about $150/month extra on my power bill. Yes, in my case it has been cheaper than wood since with wood I heated my basement also, and liked to keep the woodstove cranked right up to keep the chimney clean and heat both floors.With the heatpump, the basement is cool but not too cool. In the summer, the heat pump is way more efficient than my air conditioner was. During the hottest part of the year, the AC added $80/month to my power bill. The heat pump is much better at cooling than the AC was, and much cheaper to operate as an AC too. A mini split has no inefficient ductwork to heat or cool, and loses no electricity pumping through ducts (my understanding is ductwork can sap up to 10% additional electricity). There is a dehumidifier setting that costs about $15/ month to use continuously in the hot part of the year, and I find that when used, which is all the time in the summer in my case, the AC setting rarely is needed. When the AC setting is used, there is not much impact on my power bill, so it is clearly getting a much greater cooling bang for the buck than my old AC did. I'm totally happy with my switch to a cold climate heat pump. It paid for itself in 3 years when compared to my old oil furnace, so it will be well worth it even planning on replacing it every 12-15 years or so. The woodstove is excellent backup for power outages, which can be quite long where I live, in fact there was a three day outage this past month, and as a supplement for extended extreme cold, which has not been happening in recent years. The correct heat pump is the obvious best choice for most homes now, imo. Electricity costs are much stable than heating oil in the long term. You can make your own electricity too, with solar panels. A grid tied solar power system with a mini split or geothermal heat pump is the sweetest arrangement of all, also imo.

As a point of reference, a book I own about Earth Covered Houses, stated that the minimum amount of earth coverage required to decouple a house from the surrounding air was one metre (or yard), so going down to two or three metres would be more than enough earth coverage for the piping system. The only other thing to consider is that the deeper that you dig your trench the wider it needs to be battered back to prevent collapse during installation.

That book is not very exact. Depth is dependent upon annual frost depth which in the USA in some places is over 3 feet. Certainly there are studies in different arias that give fairly exacting temperature by depth. What you are seeking is a constant temperature zone or two zones, one for cooling and one for heating.

I had my horizontal bored 4Ton system installed for $15k before tax incentives. The heatpump was a used unit purchased locally from a private seller upgrading to a larger unit with only 5 years of use on it. They were upgrading as they added an addition and needed more tonnage and a larger unit made more sense rather than a secondary. The horizontal bores were installed with 5 lines of 250 foot in length making a round trip loop of 500ft per loop. A manifold was buried outside by basement so a smallish excavation was needed for that. The manifold is thermally welded to the pipes preventing any possibility of corrosion to clamps. The loops are 1 inch in size and the output of the manifold is 2 inches all of the lines are high density PEX. Part of the install I was in-charge of getting the necessary electric to the unit (not insignificant as there is an emergency aux resistive heater that can carry the needs of the home if there is a catastrophic failure of the heatpump.) The unit was transported from the old home to mine by me but removed from service, validated, and installed in my home by the same company. The antifreeze is a 15% solution of methanol. The lines were pressure tested before attaching to the unit for 24 hours. The unit is rated for 6.1 COP at 68 degrees and 18.8 EER at 86degrees. (full loads reduce those efficiencies a bit). Another point to add is the de-super-heater. This permits me to offset my water heating costs by dumping heat into a potable water buffer tank that pre-heats my well water allowing my main water heaters to work less hard. I could have higher efficiencies with a variable system rather than a 2 stage and a variable pump rather than a fixed but it made more financial sense to buy a well cared for, inspected, used unit with proper service records than it was for me to purchase a new unit with these more advanced features. At some point I might upgrade the unit but even then the costs will be far less as the lines will never need replaced and have a 100 year warranty. The expected life time from a unit like this is in the decades so a unit with only 5 years is just getting started. When I was evaluating this I too was in a predicament with the cost to install natural gas at $80k and propane costing around $1500 for half a year. I upgraded my whole house and removed the old propane fixtures installing an induction stove, a heat-pump water heater, and an on-demand electric water heater. I also had solar panels installed that cover all of my electrical needs for over half the year. I also have an electric car and electric mower so those numbers could be higher for a person who drives a gasoline car. As a point of reference I have a builders grade home built in 1985 in NE-OHIO (Zone 5) that is 2016 square foot.

Another point of geothermal is the benefit of no exterior noise, there is no external air handler that is making noise. One negative is the speed of heating is slower on a geo-thermal system as it outputs less BTU per unit of time vs a fossil fuels system. This means if you normally turn your heat way down when leaving the home the time it takes to re-condition the space will take longer. (honestly I don't notice this much and when I leave my home the heat drops to 55 and the AC goes up to 88). A positive is that there is no inherent need for air changes like a traditional fossil fuels system (like I had) that drew air for combustion from the home and exhausted it out the roof. This means it allows the home to leak less air during heating seasons as less air is drawn in though cracks to replenish the air lost though the flu. Air moves slower also on a geothermal unit meaning the ducts are quieter and less dust is spread around. There is also no risk for CO poisonings as there is no combustion occurring. This lowers my home insurance costs as there is less risk of fire. A ground source AC geothermal unit is also more efficient than and older central air - air sourced cooling unit. As said in the video the efficiencies don't vary due to the weather as the ground temperature remains constant. (loads will vary and that can effect efficiencies (what stage is running or the set temp inside the home). I was also able to sell my old central air unit and furnace for 1k offsetting that out of pocket costs. So after tax incentives and the selling of the old furnace unit my costs were only $9.5k. For that cost I have a system far more efficient, that adds value to my home, improves the air quality, and can be powered by solar. If I ignore the electrical loads and only consider the propane saved with this geothermal unit, I have a payback period of about 4 years. Obviously this ignores the increase in electrical usage from other propane conversion (offset by solar), the reduction of electrical usage in the cooling seasons, the reduction of home insurance, the improved efficiencies of the home system and air tightness, the improved health with less dust and CO/CO2 production, the noise reduction or longevity of a geothermal system vs any other system being exposed to the elements outside or dealing with flames.

I was told the rule of thumb for horizontal bores (not trench laid loops) was one 250 ft length (500 ft total) per ton of heat/cooling. They installed 5 loops to allow additional buffer. I also was told vertical wells are a bit more efficient but come at a higher cost due to the need for a well to be dug. As far as landscape goes except for the disturbed land next to my basement wall where the manifold was installed you would never know that there was any system present. This is nice if you are in a rougher neighborhood as theft of AC units happen in some neighborhoods. Previously I had a 3 ton AC unit, 4 Ton was a better fit when calculations were being preformed on the required loads of the home.

Is the flow in each of your manifold lines equal? Do you have a strainer in the system in case bacteria start growing? Propylene glycol by itself isn’t adequate. You need something luke dowchill with the additives to prevent critters from growing.

Could you show more pictures or more video time of your actual work? That would be awesome!!

Great video, very well explained. Your system and the logic behind it is great too. Good job. I love you can do it yourself attitude. But you need to redesign your manifold as yours will not have even distribution of flow to each run of pipe. They will be significantly different and it will decrease your units efficiency proportionately. You may think that it is possible to balance it with valves, but a new manifold is a much better idea as that will reduce efficiency also. The manifold pipe diameter has to be increased greatly. I would increase it by a factor of between 4 and 8. Your feed an return lines to the pump can remain the same. If you do this you will guarantee that each line has equal pressure. I hope that this helps. 👍

I think going deep was a smart idea. thats around the point where your're going to have a consistant temperature year round.

By adding geothermal to heat and cool as well as to produce hot water (in addition to using 12 volt LED lighting and other efficiencies), I was able to cut the size of the solar generation requirements by almost 60%. If you go with geothermal, make sure you replace your hot water heater and use a superheater coil connected to the geothermal loop. That extra savings helps justify the costs and keeps any renewable energy costs down.

I am in SoCal too, looking into ICF can you let me know which supplier/builder you used for the ICF?

I’ve loved/wanted a gt system for years, but never felt I could afford it due to front end costs. I live in Big Bear, SoCal n would do it now but have had trouble finding someone who has had experience with gt. Any info/referral would be greatly appreciated. BTW One of the big SoCal universities did a study n figured if LA went geothermal They could save 40% of current electricity demand (everyone runs ac most of the year.) That makes green energy much easier to implement n reduces heat n hydrocarbons in the air. Let’s do it!

Great video. I've got a 5 acre farm, 4 producing alfalfa and one doing squat with a massive 50x100 shed I want to temperature control & grow food in year round (Colorado). THIS is exactly what I've been thinking of albeit I now need to start pricing the units & how to build the manifold. Will watch other videos now.

Sierra Foothills in the Gold Country of CA. I’ve thought of installing one for the last 20 years, but the installation costs just didn’t make it viable. Thanks to you, my dream is back!

totally imformative and well delivered thank you

Glad it was helpful!

Lots of good information. I had a heat pump back in the 80s. It was crap for heat, and the compressor went out after 5 years. I was told that was good service at the time. Unless they have improved greatly I would never have another. Geothermal is the way to go.

Heat pumps have indeed improved greatly since the 80's. Roughly 30-40 years of advancements. These new units can operate down to -30° and offer 90% efficiency rating to 0° F.

My last heat pump, a two speed Lennox, lasted 27 years. I just replaced it last year.

l just built a new house here in Maine. I have Misabishi H2 for heat pumps. they are my primary source of heat. this type works extremely well.

This is awesome. I'm in Virginia, this may work pretty well. We do have a lot of red clay, hopefully I can set up our retirement homestead and implement one of these. Using this to run a small self-sufficient farm for my retirement work and allow support the local community.

I'd love to do this on my dream home build!
