To everyone commenting on the size of the radiators I would just like to point out that from June 15th 2022 new Part L building regulations will require all full central heating installation including gas boilers to be low temperature of maxium flow of 55C

What it means in practice is that even on gas boilers you will have to install radiators of considreably larger sizes and in older properties it simply means radiators of similar size as in this video for rooms with comparable heatloss.

See below

"A revised version of Approved Document L (Part L) of the Building Regulations has been published which will take effect from June 15th 2022. With this revision there are a number of changes to guidance and requirements covering both the new build and retrofit markets.

With regards to existing dwellings the main points are:

Complete New System Installations require:
An appropriate heat loss calculation for the dwelling
A system sizing methodology that takes account of the properties of the dwelling, such as the Chartered Institute of Plumbing and Heating Engineering’s Plumbing Engineering Services Design Guide
The system should be designed to operate at a 55°C heating flow temperature"

Here in the southern United States, we use forced air heat pumps very effectively. In the event of the extream cold, it is backed up by electric resistance heat. This back up heat is seldom needed but can also act as emergency heat if the compressor fails. With the very hot summers the ability to provide air conditioning makes this the most practical system for most southern states.

I am from Romania and I am a woman. Your video was helping me incredibly! So thank you In my country, heat pumps are at their beggining. But due to energy crisis, there is crazyness on the market. It is a jungle, actually. Huge lack of knowledge, few good specialists, and lot of abuses. Myself I started to learn a bit about heatpumps and installations after having a very painful experience with an insltaller claiming to be an expert. I found no other solution than to start learning myself, learning the heatpump installer manual like a bible and start testing really well the so call "experts" offering to reinstall correctly my pump. Was it enough? yes and no. But... your videos were solid milestones for me, on the road to learning from the best. Therefore I am sending you my entire gratitute. Love from Romania 💜🧡

Nice install. It's of the outmost importance to reduce the Average temprature of the water in the system. Every degree that the temprature is reduced is about 2, 5% Efficiency. I have a Geothremal heat pump and my Maxium temprature is set at 28C. Noramlly the system runs at about 24-26C. Last year I had a COP of around 6.5, including warm water production. A lot of people on here are saying that the install is complicated and saying that doing the caluclations on the average heat loss per room is too much work when really they should be doing this work regardless of what system they're installing.

Looks like a very good installation. Well it wouldn’t surprise me if this installation cost £15, 000-£20, 000 probably slightly more. In my opinion I think this is way too much money for most families to go down this route.. personally before installing a air source heat pump I go down the route of installing insulation possibly new windows and also looking on how to improve the buildings fabric to decrease heat loss. From my experience as a heating engineer, heat pumps have a place but most the time badly installed and proper care and do diligence is not taken while surveying the job.. I personally would advise people to look into how to make the property more energy-efficient through wrapping it up then installing a heat pump on old properties.
Now if you had a brand-new property that was 100% up to scratch building regs regarding insulation or possibly a passive house then a air source heat pump would be ideal specially if you have underfloor heating everywhere..
Personally I think spending £20, 000 on improving windows, insulation etc is far more bang for your buck

I've watched Rogers videos and to be honest nothing he said is false. Heat pumps can be made work in every house but they are not the best solution for every household. Maybe the running costs he talks about are more down to bad installs rather than the system itself

Those two huge radiators look ridiculous.

[HeatGeek]

Absolute pleasure working with you Simon. Your a great embassador for the industry!

[Lutonman]

My god. What on earth have your customers got to do for a living to afford this monstrosity of an install. Most of my customers are scraping together the money for a 2k combi swap. As always the standard of your work and knowledge is unquestionable, and I’m sure all of us heating engineers can appreciate seeing someone doing something perfectly to the book, but for millions of people in this country this technology is simply a financial non starter and will never be affordable or practical. As far as the changes to the building regs, I can tell you now that hardly anyone is gonna do it. Just like the ridiculous Erp sticker calculating fiasco, that’s largely now just ignored, or boiler plus which is often again just ignored for people on fixed incomes then every penny counts and new controls are often an expense they won’t go to. These giant 20k heat pump installs are just pie in the sky virtue signalling for the middle classes. I’m calling people this year, regular customers for a boiler service and being told by them they can’t afford it. Yet more regulations coming in to make installs even more expensive for people. I’ve got fifteen years in this industry left till I retire and I can’t wait.

Payback time ? Radiator aesthetics? I've been designing central heating systems for 50+ years, those radiators in the music room may do the job, but they look horrible , my customers simply would not have them, and you haven't got enough wall space for horizontal ones, that's going to apply to every room , by the way, your pipework is excellent , regards Steve

[dudeatx]

So they cost a fortune to install, generate relatively little heat, need highly skilled fitters (good luck in UK) and need more pipework than a power station. But, hey, they "work".

[wayinfront]

Complete nightmare. Avoid at all costs for as long as possible, until the government force you to have these wretched useless things installed. Hopefully by then there will be such an uproar that they'll abandon this stupid idea.

[Chiller]

The pipe work alone is insanely complex, bordering on artistry. There must be miles of copper in that building.

[SisterAbdullahX]

Excellent work, as always Szymon, but I think this video kind of makes Roger’s point. That install must’ve cost at least £20k, that prv pump alone was £700! And having to fit those massive radiators, including those TWO great ugly things in the lounge! Yes, you’ve shown that ASHP can work in old, solid walled houses, but the cost and impracticality/ugliness of the system will definitely put the large majority of home owners off, as would the running costs. It’s only the well off, virtue signaling “I’m doing my bit” crowd who would entertain that kind of thing.

[georgeturner]

Great video. The installation highlights the serious issues we face with old UK housing stock. Heat loss is the enemy in winter. In summer it’s going to be cooling. I think we have to seriously invest in super insulation before we install heat pumps. Most “ ordinary “ households won’t have the funds for these high end systems. I’ve invested in second hand woolly jumpers. Heat the person not the space perhaps?

[lexwaldez]

It's always about the installation so finding the right people is, as always, super important. I mean the equipment is important but without the right installers, it's never going to work right. It's always about hiring the right people. Hire the right people and they'll make sure you get the right equipment. FWIW we got a new heat pump last fall and it's been AMAZING. Rising power prices and our monthly bills have dropped significantly. Love it.

Heat pumps work PERFECTLY fine. I installed an air source heat pump in my home last year and it works perfect! European countries who import Russian gas are feeling the pain and horror of buying Russian-fascist fuel that aids in killing innocent people. And gas is a huge contributor to climate change so we need to install as many heats pumps as possible, and solar on EVERY roof top in existence.

[jeffjackson]

I'll be honest watching this is like watching a master artist paint a masterpiece: everything is perfect! I wish I could count on every installer to know how little forgiveness there is on this style of installation!

[locomotive]

As i and my company already installed over 1500 running mashines over the course of the last 23 years i can say: They work, you just need to know what youre doing.
But our system run at 35°C in and 28°C out temperatures so you need an under floor heating system or special radiatiors with fan support.
with these radiators you dont need to plaster your living room wall with radiators.
holy moly ... my customers would look at me and would ask if i have undiscovered psychological problems or something for even suggesting that.

[brentsoutar]

In Australia we just use air based split system heating. It's quick to install and seems a lot easier than the amount of pipe work done here. I have a bunch of Aircon units in my house in all the bedrooms 2.5kw and lounge rooms kitchen etc 7kw and they all function as heaters and air cons. If one breaks all the others keep working. This solution seems overengineered and probably prone to failure as well as probably many many times more expensive. On the other hand looks like nice work 😂

[videomandan]

there's no way this system will fit in my new build house not to mention 35% of my patio will be gone and then i would need to protect this pump from my son kicking a ball
