Thanks for having me over John and the invite from Roger! Glad I was able to show the poor install practices that left poor Johns wallet being hit double time! If you want to be assured that your heat pump will work properly please use a trained Heat Geek!

[@robthomas7232]

This is exactly the follow up video we needed on this and I'm glad you spent the time Adam (and John, Roger and mug breaker) to do it. I was one of the people on the original thread saying to get you and Simon from urban plumbers involved. I think showing how what was wrong with a real world poorly designed and installed system and how they can be fixed can provide more confidence to consumers than some of the more theoretical videos. I'd love to see Simon get involved and maybe a manufacturer to implement your recommendations and then a follow up with John who can they explain the differences and hopefully improved experience once its bedded in for a while. Once again well done for coming together on this and I will be recommending Heat Geek installers where I get the chance.

[@johntisbury]

Good analysis and synopsis Adam. Such a shame John was wanting to do the right thing and has been sold and installed a dud.

[@jeffmeier1663]

I was a process control specialist in the chemical industry for decades. Many of the problems you highlight are very similar to where I made my living providing training and consulting services. I had an air source heat pump installed in my home in the last month in the US. They wired it such that it would run at high speed all of the time along with other errors in control logic. This would have defeated the improvements I was expecting from this swap. Luckily I knew how to fix it and rewired it myself to run properly. They even argued with me that the installation manual from the manufacturer was wrong. My previous one was wired wrong as well 15 years ago. They also installed more backup heat than I specified that would have used 2X the power necessary during defrost. I talked to the owner of the installation company which is one of the largest in my area. She agreed that low voltage was an area of weakness in our country. I suspect the installed COP in most countries is far from what these systems could achieve with more optimized installation practices. It is likely many of the decisions made by installers are not only out of ignorance, but also out of reducing call backs. Tweaking systems for maximum efficiency tends to push the system against comfort and equipment constraints.

Absolutely one of the best SB videos in this series. It's great to see Roger and Adam finally on site and getting onto the same page. I do hope that John has the confidence to turn this installation around.

[@davidstorm4015]

What a great video. We've had our heat pump for 8 years and it is still running really quietly, it's a big pump (Samsung 16kw) to heat a big house. We don't have a buffer, everything in the system works fine. My only issue has been that the installer didn't explain anything about weather compensation and they had set the temp at a constant 45c, just like the installation in this video. This, combined with the fact that we have a Honeywell on/off room thermostat was causing the heat pump to cycle on and off too much. I have taken it on myself to learn how to set it correctly for weather comp and I now have it running successfully at a much higher efficiency and the house is still warm all of the time. We're achieving a SCOP of around 3.2 in Winter and 4.2 for the rest of the year, compared to 2.0 and 3.0 as it was set up previously. Very happy with it now, I just wish our installer had set it up this way in the first place.

[@richardhuff2796]

Rodger one of the best videos I've seen on explaining a product, I was transfixed even though I've no intention in having a heat pump but the heat geek guy was great. 👍👍👍

I’m an Engineer in AC and refrigeration. Don’t touch this stuff with a barge pole. It’s basically Airconditioning system. It will not last long before either the printed circuit board or compressor fails and the cost of parts and labour of people with half a brain is expensive. Plus technicians aren’t that clever. Most engineers are guessing and you will pay for parts you don’t need or many times just lots of parts at once to cover all bases and the bill will be horrendous. What it all comes down to to is the uneducated get a raw deal look at Kovid look at the general population normies who went for the lies now the same people are gonna be getting this installed. Lambs to the slaughter.

[@paddycairns1972]

John, you have my deepest sympathies- I built a new house 13 years ago and fully intended to put in an oil fired boiler. My plumber convinced me that wasn’t the right thing to do as the government had grants out for green heating and he was working with a boiler engineer who could install a wood pellet boiler. It was a disaster from day 1, struggled to heat the house, no hot water (sound familiar), and like you I threw more money at it to try to fix it. It’s like quick sand - you’ve invested so much and these engineers keep promising one more tweak and you’ll be sorted and nothing. Anyway to cut a long story short- after 2years of misery (and a lot of soot) my wife rang me to say that the garage where the boiler was full of smoke- so I got a really reputable old school plumber in to install an oil boiler. The guy who had installed my original pellet boiler fled to Canada leaving a trail of destruction behind him(having gone bust). I do think the government have a huge amount to answer for- they bring out grants and suddenly everyone with a van is an engineer and when the grants go they evaporate. My heart goes out to John because my experience was very similar(it’s funny I even recognised the look on your face when the heat geek guy was talking about 350% efficiency- I had the same look). I do sincerely hope it works out - the heat geek guy really does seem to know what he’s talking about- I wish I had someone like him 13 years ago.

[@1960ARC]

Anything pushed with grants is going to be a disaster.

[@bernie129locksmith]

You hit the nail on the head - overcomplicated systems that cost a fortune and are only affordable due to grants and the fiddling of energy prices to make gas as expensive as electric - You could replace the whole lot in this video with 1 gas boiler and it would be greener in the long run if you factored in replacement parts and the amount of times you will have to repair and replace parts - Its like walking around with a grandfather clock on your wrist when you could just wear a watch

Adam came over very well here! I was critical of him in the first video. However here in a real situation it was truly fascinating to listen to him pick through the issues. As Roger said, I was too was surprised he was in effect sayings it’s been made me overly complicated and would have been a cheaper install if spec’d properly. The external unit needing to be replaced purely down to being on a poor subsurface is the kind of thing most people would overlook, I certainly didn’t think about it. But stood to reason once explained! Hopefully Johns wallet and passion to get this working can spawn another episode to conclude once the recommendations are implemented

[@nickrider815]

I think his heart is in the right place. But he didn't fix it did he. He basically said the pump is trash replace it. I'm dubious if any of what he said would work and if would it continue to work. A 1 year guarantee of efficiency (which they aren't even offering yet) is pretty short and pointless on a system that barely provides enough heat to begin with. Remember the consumer goods act says products should be fit for purpose and last 7 years. A £7k heating system isn't something you can afford to replace once a year! I was happy to hear Adam out, but he didn't say or do anything to change my opinion of the tech.

[@daveslater6156]

@@nickrider815he was in a difficult situation there. The pump had been installed incorrectly by a firm that went bust straight after. Warranty on anything is based on it being installed correctly so LG are unlikely to honour it. Given the high rebuild cost that John would have to pay out of his pocket, plus the fact it’s a wrongly spec’d unit for the job anyway, Adam was advising John he was probably better off cutting his losses with that pump and installing another. As a result, with a simplified system he would probably be able to buy a cheaper unit than the original and then have the advantage of a warranty moving forward, which still wouldn’t exist on the original pump even if he got it repaired.

[@nickrider815]

@@darrencoyle3290 I'm going off what Alex said, that it was scrap. Also in the last video they said LG wasn't returning calls on this one. Plus manufacturers warranty will only be valid in accordance with correct installation. So the warranty will be invalidated in this instance. I have spoken to a lot of heating engineers, plumbers and several actual owners and a part from one they all regret installing these things. Heat Geeks offer to maybe one day guarantee a 15-20k heat pump installation for 1 year with caveats isn't going to change my mind.

[@simhedgesrex7097]

@@darrencoyle3290 That would be the case if the boiler is no more than 5 years old AND if it was fitted correctly according to LG's specification. So if the spec says "ensure that the heat pump is installed on a level surface" the warrant won't apply.

Great to see a sensible discussion and show that bad fitting leads to bad performance. It is great that you are helping to get this fixed.

Hats of and standing ovation to Adam! I’m a heat pump and systems engineer in Sweden and this is the first video I’ve seen that got it all right and was able to explain the function to the customer in a sensible way, even the more technical parts 👍al thow it was quite obvious that he was holding back, god job.

[@davezipman8959]

Brilliant Roger - let's see this one to a conclusion please. Now Im an aeronautical engineer with 45 years experience and I've not met a device yet that I can't change the bearings on - so don't junk the heat pump! Sounds like the fan motor bearings (just like the usual problem with a flue fan in a boiler!) and LG sell new motors for £300 ish and its a simple 2 minute replacement. Even if the motor isn't available from LG as an assembly, any engineer worth his salt could replace the bearings.......and the thing is out of warranty anyway! Maybe its in LG's interest to get involved here and promote their after sales support?

[@davezipman8959]

PS Just checked fan motor and bearings are available - genuine LG parts

[@Wayfarer-Sailing]

A conclusion/follow-up would be great, but wasn't part of the point that the LG heat pump seen here is a 2-stage unit, which is probably not necessary?

[@davezipman8959]

Surely fixing the existing unit would enable John to gain confidence the Heat Geek proposals before the neighbours go mad with the noise - then decide on a single/dual stage unit longer term when he sees aCOP of >3.5 is possible?@@Wayfarer-Sailing

[@johnwynne-eyton1165]

Not just with heating either. Finding a true tradesman that is proficient, knowledgeable and conscientious is nigh impossible these days.

[@Acecross]

Great video. I’ve loved watching the story unfold and Adam recalibrate Roger’s scepticism. I’d like to see what happens here and hope the efficiency can be improved.

[@HYUKLDER1]

On homeowners not being technical about heat pumps, the problem begins before that. Homeowner should not be specifying heat pumps based on advertising and politicians' PR, because that's like telling a doctor the diagnosis before reporting symptoms! The first call ought to be to an independent qualified heat loss surveyor to get a report on the building's condition regarding heating losses with recommendations for what changes are required to achieve the best standard of efficiency. That may or may not be a heat pump and other changes required, but at least the recommended comprehensive solution, if installed correctly, ought to work as well as it can.

[@tlangdon12]

This is great advice, but there are precious few qualified heat loss surveyors available for hire. Given the antiquted state of Britain's housing stock and the current price of energy, we should be awash with them.

[@ricos1497]

The issue there is that it's an additional cost, and additional person to get round. People likely see that as inconvenient and just expect their heating engineer to do the heat loss part for them. Ideally, heat engineers would do a proper survey as their first task and then install the appropriate unit. There are probably a few reasons why that doesn't happen. The first is that, as you say, the customer phones a heating engineer asking for a new boiler or "one of those new heat pump things", rather than asking for a new heating system - they've already diagnosed, as you say. Secondly, the particular heat engineer is likely used to one particular system (usually gas) and will be predisposed to installing that. Thirdly, properly insulating a building in the UK can often be extremely disruptive (unless external clad), time consuming and expensive. You don't get the same feeling as installing a tangible boiler unit. I expect the customer is often just after a quick fix, and the heating engineer wants his sale, rather than having to wait for internal insulation to be done, often room by room - or have to work around that ongoing building work. I suspect that's why people just throw back in a gas boiler in the end, and heating engineers are happy to oblige. The focus should always be on energy reduction first, energy supply efficiency second, but doubtless that almost never happens.

[@simhedgesrex7097]

Once Heat Geek get their guarantee in place, then they can quote on that basis which will enable you to work out your savings, and they you'll be able to safely proceed on that basis.

[@normanboyes4983]

Thank you Roger and Adam for doing this video. I have every sympathy for the homeowner. I truly hope those cretins who installed it and the cretins who modified it have watched both of these videos and give the homeowner his money back so that he can pay Syzmon to sort it out properly. (I know the installation company went bust - but you know what I mean). Even if LG cannot provide a sensible service any competent mechanic could replace the fan bearings (LG ado not make bearings), they are readily available and cheap. I can well understand if the owner goes back to gas and has nothing more to do with the Frankenstein system he has ended up with - It would be great publicity for Vailant or Viessmann to get onboard with this and prime the funding to enable Heat Geek and Syzmon to sort this out.

[@alanbrown1345]

Solar company went bust (no surprise there) but need solar panels refixed and new battery (expensive).

[@timhancock6626]

I put the Ideal weather comp kit on my Logic Heat Only gas boiler. It took a bit of getting used to cooler radiators, but it certainly works and has saved gas and money and the kit was less than £100. I'm retired now, but I was Gas Safe registered at the time. Incidentally, when it was -4C yesterday the flow temp went right up, just as it should. Go for weather compensation for sure if your system can support it.

Well done guys. This video encapsulates the real set of issues we've experienced so far in our journey toward energy-efficient home heating. If John's installation can be simplified, his heat pump fixed and the system made efficient, I think these 2 videos would be the best marketing the industry could get 👍

[@graemejones218]

Hello Roger. I was very lucky to get the government grant for the whole system, that being solar panels x 10, 7 new double convection radiators, the external fan cold to hot water heater, a Kodiak boiler with a digital interface, 2 expansion units above the boiler, & 2 thermostats (1 for upstairs, 1 for downstairs). My house met the criteria on a couple of points. Octopus asked me if I'd like this & I was elated, out with the old eco7 heaters & the immersion heater. I now wish I'd never had this installed. The rad's are luke warm at best, the outdoor fan unit switches on & off constantly & the electricity cost has more than doubled. As I write this at 11pm, it's -2c outside & 12c inside. The rad's aren't being heated, just the hot water for the boiler. I echo John's original interview, it's very expensive to run, it feels too cold, & I don't have gas to compensate. I was told the rad's were working fine & that's what I will get heat wise. I've got so many valves, those pumps that Adam stated weren't needed, & my boiler is set to 50c. I live alone so I just live in the kitchen as it's the hub of the house. Out of my own savings I've replaced secondary glazed windows for new upvc double glazed units. Last winter it was just 6c inside this kitchen, now it's 12c so they have helped. But for all of this cheaper heating installation, those rad's are useless. Like you say, it's fairly new technology in the UK, & after watching this follow up with Adam, I think the installers didn't have the knowledge or training. They were just plumbers by trade. As of now, the rad's aren't being heated, they are stone cold at the bottom, & the heat exchange unit is using 93p per hour. My tap water will burn your skin off, but the water will not provide adequate heat to the rad's. I think I have too many unnecessary parts just like John. Something isn't right, as confirmed by your excellent video here. Very unhappy although at least the heat exchange is level & quiet.

Interesting video, I have been a heating engineer for 35 years and admit I’m stuck in my ways and too old to be interested in installing heat pumps now, but still interested to see how the domestic heating industry is changing, Rodger brought up a great point at the end regarding manufactures repairs and warranties, the cost of these units to buy and install should be covered by a substantial warranty, the poor customer there has had that LG heat pump for what six years and it’s basically now scrap, due to poor workmanship, no one should be allowed to fit these unless they have been on either a manufacture course which would then sign them off as a registered installer or a professional registered company such as heat geek that can provide the necessary training and accreditation, it’s stories such as this that’s still putting a lot of people of having these still unfortunately.

I was a total heat pump sceptic until we had one installed in the 200 year old community centre that I help out in. Thought the fans would be noisy etc. Wrong! Runs extremely quietly, constant heat throughout the buildings and the control panel lets us know what is going on in each room separately. Might look at installing one at home too!

This is a brilliant video, it's great to see that you've gone back to try and help John out with a proper expert in Adam. I hope it's all finally put right for him. There's a lot of people that think they know what they're talking about, but Adam actually does know and that's a rare thing these days. Although I'm still an advocate for installing an air-to-air HP in my own house, it's still interesting to hear about what to look out for if I ever change my mind and decide on air-to-water. As a final, Jaysus Christ those fan bearings are screaming in pain! I really hope that they can be swapped out for decent ones without changing the whole fan assembly.

[@tlangdon12]

Air-to-air can be good, but the wall units are quite large, and can dominate a small room. They look like they would expensive to have a wall unit in each room. We have 10 rooms in our house that have radiators in them currently, so we would need a very large outdoor unit (or units) to support 10 wall units. I'm not sure we have the outdoor space for what would be needed. We are also used to having stored Hot Water, so would need an air-to-air system to provide this.

[@mazdamaniac4643]

@@tlangdon12 We use air-to-air HP's all over the place at work and that's where I've been taking my inspiration from. The air handling units aren't that large, I have a tower fan sitting in the corner of my room right now that is twice the size of one of those units and it isn't a problem, this feels like a bit of a perpetuated myth on how big or intrusive they are or need to be. You also probably don't need 10 seperate handling units if you have 10x rooms. My house has 8x rooms and through physics, cross-convection and the ducting of my MVHR system, I calculated that I could heat all of them quite effectively using 2x units, or even 1x if I really wanted to push it. The heating engineers at work agreed that was perfectly fine, when I showed them a drawing of what I wanted to do. Likewise, you don't need a massive industrial-scale external unit to accomodate 10x air handling units, the only major things in that unit are a compressor and a radiator...the rest of it is in the interior air handling unit. The external units are usually significantly smaller than their air-to-water cousins. You just scale up either/both the compressor and radiator as needed, one basic external unit is usually capable of feeding up to 2-3x air handling units before it hit's it's limit and needs upscaling, so the guys told me. You could probably get away with either a single upscaled external unit, or two smaller units delivering for upstairs/downstairs respectively. At work, one of the office buildings is done like this and it's the size of an average warehouse, the air-to-air external unit just for that building is the size of a small motorcycle. That's absolutely tiny in relation to the rest of the building, but it's actually over-sized a little so it's not running flat-out all of the time. I remember being shocked at how small it was, yet was delivering so much. It's been going for over a decade now with no trouble and usual basic sarvicing...because there's hardly anything that needs to be serviced on it.

[@michaelviney3737]

The big flaw in our geek’s augment is that most homes with a high temperature gas or oil fired boiler do not have the central heating on in summer and then only for short periods in autumn or early spring. Winter is the only time when the central heating is on most of the time. The comparison between heat pumps and gas or oil boilers should be for winter only. ASHP COP for 0 to -10 degrees? Is 1 to 2 ie 28p to 14 p / KWhr Cost of oil today 8 p/ KWhr ( source Nott Energy consultants) The geek used thenSCOP annual figure of 3.5 which includes summer. And had the ASHP low temperature system running all year using weather compensation to adjust flow temperatures. Resulting costs far higher as WE DO NOT USE our central heating in summer . ASHP systems cannot give you a quick burst of heating if it is a bit chilly. I have oil and will continue with it . Happily the alternative HVO replacement oil will soon be widely available and its price will fall in time. Only need to change a jet on the boiler. Finally imagine a cramped new estate with each property having ASHP s running. The noise frequencies will differ a bit and will resonate!!

[@tillyfoxtrotter]

Agreed - the manipulation of heating stats to include summer time seems to be continually overlooked, ditto the insulation - all systems use less fuel if the house is insulated more highly. Never do we see an apples and apples comparison. We also have oil and it has been consistently cheaper than gas for the past 9 years - sometimes considerably so. Throw in buttons to service and zero cost standing charge and it will be a cold day in hell when this house converts to ASHP.

[@garage3022]

I just did my own ASHP install on a 213m2 new build. The results are fantastic. It pulls only 800 watts to keep the house at 19c at -2c outside. The old house this replaces had an oil fired boiler and the costs to run that were atrocious. Now fuel oil is very expensive here in the netherlands I must add. I was a heat pump critic but not anymore. Its dead quiet as well

I installed a smart electric combi with seperate elements for heating and hot water. The heating only gets used in 3/4 months the instant hot water provides for showers ect. Combined with PV solar and old diddy heating allowance I save money, a heatpump running 24/7 would be using electricity when not needed.

[@BarriosGroupie]

A gem of a video, which has re-shifted my confidence towards heat pumps installed in Britain's mild climate, providing the site and system is correctly surveyed competently beforehand.

Thanks Steve. People often think that I don't like being proved wrong. I genuinely wish I was completely wrong about heat pumps and their unsuitability for some homes. Sadly we are still getting countless emails from people such as John. Why did I pick him? Because he lives ten miles away from me and not much more from Adam which makes it easy for filming several episodes.

@@SkillBuilderYou are welcome. Most of us don't like to be wrong, but being able to listen to other perspectives (and shift our own if/when that is needed) is the only thing that will save us all from the horrible and polarising social-media (or 'outrage media' as it should probably be called) madness that we tend to experience these days. It was fab to see someone prepared to take a genuine interest in an alternative position to their own. What would be really interesting now, would be to see the suggested changes implemented, and then have the home owner and you report back on what (if any) impact they actually had. Sounds like the cost would be a days internal plumbing, £300 for a ASHP service and new bearings (based on some other comments in this thread), and then perhaps half a day of a builder to correctly seat the ASHP. If I was the home owner, I would definitely be prepared to give that a go (accepting he's spent a small fortune already).

[@twig3288]

What I like most about heat pump systems is their simplicity 😂🥶

[@markyates5744]

They said condensing gas boilers would never catch on. The installers said they weren't worth the premium! Who needs circa 90-95% efficiency, gas is so cheap 65-70% efficiency is fine! For the last 5-10 years anything not condensing is instantly condemned as inefficient and wasteful! Simple way to tell if your boiler is condensing - does it have a water drain valve at the bottom? If it doesn't it's not a condensing boiler!

[@gav7507]

I think the biggest problem with heat pump installations in countries like the UK is they are trying to retrofit them into houses that have extremely old radiator heating systems which are based around pumping water all around your house. Pretty much every house in Australia has a heat pump air conditioner/heating system and it's much more simple over here as we use them to heat or cool the air which is blown through either a whole-of-house ducted system (which can be zoned to certain rooms) or split heads which are placed around in separate rooms. There are also some other types like cassette systems that sit flush with the ceiling. A whole of house ducted system costs the equivalent of 5000 pounds or individual splits around 650 pounds. By instead using them to heat water instead of air you are introducing so many more points of failure. Water leaks, blockages, pump failures, heat loss And before someone comments that Australia isn't cold enough so not putting heat pumps under much stress Canberra has a similar climate to London and our record low is -23c. Looking at the climate data for the UK -25c is pretty much the coldest it has ever gotten. My air conditioner is rated to cool up to 52c and heat down to -25c

As changing those doesn't break into the refrigerant system, hopefully Szymon could fit those rather than needing to drag out a refrigeration company.

[@ashtontechhelp]

A quick note on South-Facing placement: You will notice that the North side of a building will hold on to snow and frost a lot longer than the other faces of a building, particularly the South side. You will also notice that temperatures are measured "in the shade" - I believe this is because there is no heating of the ground at the measurement point, so you are measuring air temperature that has not been additionally heated by warmth coming from the ground. Consider: If we are hot, we move into the shade to get some relief, on a sunny day. We are being heated directly by the sun and the air around us has also been heated because it passes over warm ground, however under a tree it is noticeably cooler, as it the ground we sit upon. This is why ground-source heat pump coils are typically laid in ground that has sun falling upon it, where possible. Therefore: If you are installing your heat pump on a solid surface and it is surrounded by more solid surface, the sun will strike that surface and heat it, particularly if it is dark in colour. That heat will be given off to the air around the heat pump. You then pass that warmed air over your heat pump, which results in greater efficiency as there is more heat to extract from the air and pump around the system. I also think that a darker casing will be beneficial for the same reason - air will be heated by the metal work as it passes over the heat pump. It might not be worth a great deal of extra heat but nonetheless it will increase heat being passed into the system, improve efficiency, lower cost. Roger will doubtless recall that a customer wanted a heat pump moved out of sight, under a tree, the performance degraded, the cost went up. This may have had something to do with losses due to losses in longer pipe work, but it is nonetheless instructive. I think therefore that there is some advantage, actually, in having a darker casing, on the South side, if possible.

[@HeatGeek]

Your mixing radiant heat with conducted heat

[@ashtontechhelp]

@@HeatGeek I can see why you might think that - but no, I do understand that the heat comes from the air, hence "air source heat pump". I'm simply positing that, when air passes over surfaces that have been heated by the sun, some of that heat will be transmitted to the air, which then blows over the heat pump vanes. The effect may not be large, particularly when you really need it, but it might make a measurable difference to overall efficiency. It would be interesting to see the testing done by the manufacturer (Daikin ???) who recommended this, to see how large an effect they may have measured in their testing. If the effect is true and measurable (yet to be determined) it's probably not enough to warrant spending extra. But , if both options cost about the same, it's worth putting the external unit on the South side, just in case.

[@HeatGeek]

@@ashtontechhelp if it’s transfers to the air then we would measure higher air temperatures…

[@messageobliquespe100]

I’m no expert having watched the vid / read the above comments - but I would’ve thought if one had a flat roof - you could have a fan - or possibly a series of fans - laid horizontally - at a height to suit for clearances etc at roof level - could provide efficient way of doing things? The bearings of the fans would be under less stress - utilising low noise bearings tech - & a larger area of heated surface would be available - even if one had to provide some shielding against wind - maybe the system being gravity fed helps too 🤔. I’m just making it up tbh - but who knows. One thing I liked seeing is where buildings are designed with walls acting as heat sinks - where they might have a concrete stem that protrudes above that provides heat / or cooling. Think most external masonry walls act as “cold sinks” so the least one should go is to insulate them on the inside. Obvious to most I suspect but even internal solid masonry walls on foundations from ground level should be insulated. Doesn’t need much insulation even if it’s foil backed insulation/dry lining. I’m getting carried away - Many ways to skin a cat is the saying me thinks

If I were John, I think I might ask that they change the system in such a way that the buffer can be taken out of the system and put back in just using valves. Similarly, the TMV and Pump on the UFH are retained until the system has been provien to be more efficient, so they could be refitted if the changes didn't work.

I have no experience with heat pumps but I have loads of experience with Air Conditioning units and Pool heat pumps which is basically the same thing. I had a property in Florida and thankfully had no near neighbours, closest was approx 100mtrs away. Our Air conditioning unit sat outside our garage side wall and only windows on that side of property were our bedroom side windows which were long but fairly narrow. Our Pool heat pump sat on the outside wall of our bedroom on same wall as AC unit but at rear end of wall as opposed AC unit near the front end of wall. Now when these units were new they were fine but as time goes by they get more noisy due to the outer casings start to rattle. As I said we had no near neighbours which was just as well and the Pool heat pump was an alarm clock effectively because it started up at 8am. Here in the UK the thought of having one of these things with near neighbours would be horrifying, it could easily start a war with your neighbours.

This was quite interesting to watch. I am in the HVAC industry in The States. When I look at all the expense for that high-efficiency equipment, that does it last all that long, I compare that to my original Heil 80% gas fired forced air furnace that is 39 years old and still performing as it should, amazingly without leaking any CO yet. However, that furnace will be replaced within the next year proactively, with another 80% gas furnace. The air conditioning equipment is also original from 1985. I selected my own HVAC equipment when the house was built, as opposed to what the builder offered. The repairs to the furnace at this point have been a gas valve and a draft inducer, and a new contactor in the condenser outside. The 3 ton York condensor with an American built Copeland compressor is original including the AO Smith fan motor. All that stated all the fan motors have oiling provisions, so they have lasted all these years because I keep them lubricated, as well as keeping the coils clean. My savings is from the lack of repairs over all those years. Fortunately our natural gas costs here in the US are still manageable for the most part. 5 years from now, who knows. Cheers gentlemen.

[@johnburns4017]

80% efficiency? That is low to the UK.

Longevity and efficiency are good, but the issue is that we all have to get off fossil fuels in about 20 years, easy stuff like cars and home heating first. Fitting a new gas system now is 15 years more delay and the corresponding say 30 tonnes of emissions (could be more for a big US house). The time to switch is now, and especially if you are a heating engineer you have the expertise to assess kit and lead a little within society - your friends probably ask what kit you recommend? This isn't a future problem any more, it's our actions right now that matter.
