When I retired from plumbing in 2005, push-fit was just starting to come in. I’ve never really used it, it was galvanised threaded pipework, soldered joints, bronze welding or arc welding plant room headers. Being Corgi registered was a real ball-ache, push-fit looks like a dream to use. No blow lamps or benders required.

Can cause a lot of hassle as the fittings can sometimes pop off if fitted incorrectly or faulty and it doesn’t look as nice as copper, also can’t install plastic too close to the boiler, needs to have a minimum 1 meter run before using plastic because the boiler can melt it, but is definitely easier to install and cheaper because of how expensive copper is right now

Try it! It gives better hot water reheat times, better efficiency on heating. You can also install much smaller cylinders. If you were to pair a 30kW intergas boiler with a 125L high gain cylinder ( joule for example) you can have under 12 minutes reheat times, meaning you can never run out of hot water when using one outlet , pretty much like using a combi but with much better flow rates. You will also stand out from your competition when quoting.

When I needed a new boiler I chose a comventional one so I could keep the hot water cylinder. The old boiler could not be used because the heat exchanger was leaking and I had to wait a few weeks for the new one to be installed. If I had a combi boiler that would have been weeks with no hot water. I was able to heat the rooms with electric heaters. Also the new boiler was a straight swap except for the addition of a condensate pipe, making the installation easy and quick. which no doubt cut the labour cost.

In my appartement (1950's with double glazing, floor, wals and ceiling insulation0 I used to have an Intergas system you've installed, and oh boy that is an efficient one, in my current house (new built in 2018) on council heat I pay twice the price for the same KJ of heat energy, I'd wish my house was still on gas and could use a Intergas system again...

Love your work 👍 Intergas doesn’t allow their boilers to be placed in unventilated spaces under 5 kubic meters though. Their electronics fail at room temperatures above 40 degrees.

Those systems are so much more complicated when compared to what you find in the typical North American home. I'm from Québec, so almost all heating is done using electricity. The only place where you will find hot water central heating is large buildings such as hospitals and universities. Filters are rare. Most systems don't have any pumps as city water pressure is usually high enough. That also means we don't have any return, or circulation loops. That's one thing that I do think we could really learn from. Must be nice to have hot water almost right away when turning on the tap. We don't pay for water, so wasting a few litters waiting for hot water isn't a huge concern. The vast majority of North American homes only have a hot and cold pipe with an electric hot water tank that needs to be replaced every 10 years.

Nice workmanship, nice to see! Only point on here is your use of a normally open zone valve on an unvented cylinder 🙁. Part G of the building regs 3.31states “motorised valve, the device should operate to interrupt the supply of energy if the electrical power is disconnected”. This is why a normally closed valve is always supplied with the cylinder. This is one of the 3 major safety devices on unvented cylinders.

Great video! Just curious, why did you use a different type of two port valve for the heating?

@UrbanPlumbers

2 жыл бұрын

The valve for heating is normally open - so when there is heating demand both valves are in resting position. When there is hot water demand both valves get energised. Heating valve closes, hot water valve opens. Hot water fires at much higher output to quickly reheat the cylinder. Heating works with load compensation and low modulation. If both valves were open you would lose a lot of efficiency on CH.

@UrbanPlumbers

2 жыл бұрын

There is no combi boiler ( unless you use storage combi) that can give you 20L /min with 45 degrees temp rise. The best combi can give you 15L / min with only 35c temp rise and it will be a monster that will require gas upgrade and most likely will be hugely oversized for the property and inefficient on central heating. Combi boilers are a solution that creates a lot of problems.

Why would a 30Kw combi not be able to deliver priority DHW for 2 showers when each shower is not going to delivering a mix of hot water vs the heated boiler HW anyway (and some aerator taps would cut that HW demands for taps and perhaps an 2 water efficient shower heads?). How can the old boiler be expected to have ever worked if never power flushed or looked to have been serviced (whats the point of fitting a magclean if never cleaned out either). Any reason the client went for Nest over a other controls (like intertec ones) and were TRVs and weather compensator fitted?

Tado have relaunched their modulating thermostats if purchased via their website. Much better option than a Nest?

Great video, thanks. Question: I have an unvented system and three shower rooms. When two or more showers are used at the same time water pressure drops drastically, what could be the issue?

your mains supply does not provide enough flow. Could be undersized mains pipework, or undersized supply to the cylinder, or it could be that this is all you can get from your mains in your area. You can try flow limiters installed at shower heads.

If you're UK based the minimum flow requirement for an unvented cylinder is 20l/m, divide by three showers and you may have your answer.

Watched this as I struggle to keep my Ideal Isar HE30 working. 🤦🏻‍♂️ 16 years old and a nightmare after the warranty ran out.

Time to replace, Isars had a terrible rep so you've done well to keep it going so long.

16 years with that boiler is a real achievement. Do yourself a favour and get it replaced.

How do you change the bottom immersion heater element if it fails? It doesn’t look like there’s enough room.

It may not look like it, but there is enough space. It is a relatively short element and once undone you can move it to the side. I made sure that it was possible by trying it before final position of the cylinder was set. However to take it out you still need to drain the cylinder, so undoing 4 compression fittings and twisting cylinder to the side is also relatively easy.

Thermal stores are good alternatives to moving unvented cylinders when faced with D2 pipework issues; they don't have D2 pipework, and still provide mains hot water. Is there a reason why this wasn't considered?

Not a heating engineer, what is D2 pipework? I agree, thermal stores are also great from an efficiency point of view. Also you get the good flow rate of an unvented cylinder and the unlimited hot water of a combi.

They wanted under the stairs space empty. Also, heat stores are more expensive.

Hello great vid. Got question about adding chemicals to the system. Can you mix different brands ? I want to add to my 3 year old combi boiler system but I don't know brand that was used earlier. Also is there any limitations of how much chemical can you use in system? Great work thanks

Best tl drain down and refill mate stick to fernox as they are quality but cheap stuff lile senital is also fine

There have been tests done that prove mixing inhibitors can accelerate corrosion in heating systems. As G mentions best to drain it down and refill with a fresh inhibitor. I’d only use Fernox, Adey or Sentinel. I wouldn’t bother with a brand different than that. There are other ways to treat system water, but it gets quite in depth. If your interested check out de-mineralising based on a German standard VDI 2035, it’s quite interesting.

So when your flushing do you not go in forward and reverse to loosen sludge is that intagas filter made by fernox

yes, flow reversal is great for picking up more debri, however I have found that some boiler can only be flushed one way. I don't know who makes Intergas filter. It does look a bit like fernox.

@@UrbanPlumbers I gathered so as you’ve got the adaptor for them one of my friends puts tees on his pipework for flushing in future it’s a good idea just takes up a little space

Is X-plan limited to Intergas boilers? Ive just had a Viessman 100-W system boiler, unvented cylinder and Hive controller fitted as S plan. Hadn’t realised this doesnt allow OpenTherm control for efficient boiler modulation on room heating & with current fuel prices wondering how to achieve OT without getting plumber back to convert to 4 pipe DHW priority system.

Well, customers as well, as combos are by far the cheapest option.

What is the cost benefits to this system over a combi. Im using around 70kwh a day of gas to heat my home to around 21-22 degrees using a Logic+ combi boiler 24kw

@UrbanPlumbers

It’s not about cost benefit, this is purely done for hot water performance and ability to have great hot water flow. This is a system that delivered superior hot water performance over a combi and also better efficiency on heating as compared to standard cylinder set ups such as S or Y plan.
