Good story m8. And true. Its even worse though. There is no global warming other than recovery from little ice age and CO2 does not affect temperature. Lots of studies found no correlation and worse again even; CO2 is THE life giving substance on earth. Plants need it to grow and the current levels of CO2 are too low, bc there is continuous binding (by tiny lifeforms) into rock. Thats where the vast majority of CO2 is now. If anything, using fossil fuels is needed and there is plenty of it. Then the question remains why they push this nonsense. I think it is 2 fold: One, for the people in power to gain power and TWO, because of the principle that mankind has always tried to free people from labor by producing more efficiently. This has brought us to the situation where half the jobs in the west are non producing/ non functional jobs. So they want to push new things all the time, to employ more people and keep money 'rolling'. Our currencies (none of which are actual money) are going down as the west is crumbling financially and economically. All this creates new tech, new products, new jobs (as you also state) and postpones the inevitable for a bit. But that wont last. One of those fields is solar and wind energy, but that only works, bc they keep increasing prices and have most of that stuff made in China, with fossil fuels. Thats all trickery. Energtically there is no gain of energy from solar and wind, as it is used now. It depends somewhat on the lifespan, which is pretty certain at this time for windturbines and for solar... probably not much more than stated. Also the efficiency of solar cell panels gradually goes down. Same as for hear pumps, but in a different way. Heat pump sounds nice, but again, you have to add all cost to make an energetic balance and i dont think its going to be beneficial. The entire circus is probably going to come crash down soon.

I live in the USA and I’ve worked in the HVAC field for almost 40 years. I have serviced and installed just about every type of heating/cooling system there is during that time, and I have seen end users who were unhappy with every type of heating and cooling system there is. When looking into why the occupants were unhappy, the root cause is just as often the deficiencies in the building envelope, as it has been the equipment itself. I live in a rural area and currently use a closed loop geothermal heat pump to heat and cool my house. It works very well for me, because my local utility offers a great rate per KW for heat pumps, my house is newer and VERY well insulated, with an excellent vapor barrier, and the ductwork was designed with extra heat runs in order to reduce the velocity of the relatively cooler air being supplied during the heating mode. I always tell homeowners to invest in insulating and improving the vapor barrier of their home if possible BEFORE investing in a high efficiency heating system; especially a heat pump system. Even the most expensive and most efficient heating system will not work well, and the occupants of the home won’t be comfortable if there is unwanted air movement through the structure, and too much heat transfer through the walls and ceilings! I have seen quite a few unhappy homeowners who were sold a heat pump system for an old, under insulated, drafty farmhouse. The poor building envelope, relatively low supply air temperature, coupled with the higher amount of air being moved, results in high electric bills and uncomfortable occupants. I always say: Just because it says “high efficiency” on the box doesn’t mean the appliance jumps out of it and cures all of your heating/cooling headaches. A good building envelope is at least half the battle, then if you select, design, install, and control a good quality, high efficiency, heating and cooling system, you will have low operating costs, and comfortable occupants!

I live in Tennessee. I designed and built my house 31 years ago as a passive solar using a heat pump. Overall I’ve been very happy with the results. During the summer the unit runs much more than in the winter. So it actually cost us more to cool than to heat. The difference is about half as much to heat due to how well the sun heats the house, providing it’s sunny out. But I have gas logs in the fireplace, and they actually can hear the house nicely.

I switched 2 years ago from gas to a heat pump. My house 1992, so not so super insulated. Yes, you should pay attention to the house insulation first. According to my experience, it is better to have several source of energy (e.g. combining it with a fireplace, what older house have, or a wood furnance, in case of price shocks or no electricity). For a 200m2 house a 12-16kw heat pump in older houses is recommendable (energy efficient houses require less kw). So in autumn and spring, heat pumps have no issues. In winter at around -14°C the coefficient goes down, this is the point where wood makes sense, to keep the electricity bill low. A 16kw can handle that, but maybe not your wallet. In my area where I live, maybe 2-3 days/year with -10°C are common.

I live in Sweden and my house has a heat pump as do almost all houses here in the far North. Mine works down to about -15c below that I use electric radiators. My neighbour has one that will work down to -25c. The heat pump is not the problem. It's the type of housing that the UK has. Even new builds are not that well insulated. We have no gas but we have surplus electricity.

Cold and dry isn't a problem for air source heat pumps but 3C with a dewpoint of 1C (a very typical UK winter situation) causes a rapid build up of ice so the CoP and duty cycle go through the floor.

In my experience, heat pumps work fine in cold dry weather. The problem comes with damp weather. If it is between 32 and 45 and humidity is high, the heat pump freezes up. It drastically reduces heating power and efficiency. Under these conditions, I doubt it is more efficient or environmentally friendly than natural gas. I also question if your system has supplemental resistance heating, most do? If the resistance heating is being used then it is less efficient than natural gas.

these prices are just bonkers for air to air pumps.. what sieze house you got? My grandparent have a 1960's suburban house, used to have direct electricity heating, they installed a air to air heatpump for less then 3000 euros, covering 90% of their heating needs over the year. Their house walls have less then 10cm of insulation, added insulation to the attic for another 2-3000 euros and their heating costs have gone down with 70% that heat pump payed itself off in a few years. Air to air pumps for a 100 sqm house should not cost that much, and in the cases you need bigger pump.. here people tend to buy a second or even third pump for basement or if they got more floors. If your house consist of many rooms, air to air is also less effective. If you got a water radiator system and your house is big or many rooms, air to water is the way to go, or even better geothermal, but more costly investment.

In fairness I don't think this Government has the skill or intelligence to manipulate the market to that extreme. Besides electricity has sky rocketed too. Rather it's men in suits exploiting a business opportunity and jumping on the carbon free band wagon. Oh wait...

The title is very misleading. The heat pumps are actually genius appliances and in the last years they have become super efficient. When I built my house 10y ago heat pumps were very expensive and you would have to consider ground-water types to get a decent COP; so I have chosen a wood pellet boiler (one of the best market had to offer at that time). Now air-water heat pumps are almost just as efficient with a fraction of the cost (both the device and esp. installation) - I'm sure that my next boiler will be a heat pump 😀. Before this winter I installed a high quality A/C unit (Mitsubishi 12000BTU) with the possibility to heat using its heat pump (rated with a COP of around 3-4 for my area - Romania). I successfully heated half of my (two storey) house with 100kWh per month and burnt around 130kg pellets LESS (per month) - if you do the math the wood pellets give around 600-700 kWh; of course my COP was not 6-7 but the difference is in the wood pellet boiler efficiency (rated at 85-90% but i'm sure that it's waaay less). Worth mentioning that my house is extremely well insulated (proabably pretty close to passive house reqs.) Now, I said that the title is misleading because the issue is that houses are not well insulated not that the heat pumps are bad. UK's govt should help people insulate their houses better and THEN replace the gas boiler with a heat pump (you do more with the same money). It's a pity that people in general are not too educated and they don't see the point in investing more in their insulation (either for new constructions or retrofitting already built ones) although, when they move in, they are unhappy; in my opinion THAT is the real solution to this issue and it applies perfectly to all hot/cold/humid/dry areas - INSULATE BETTER! HEAT PUMPS ARE THE FUTURE, BUT OUR HOUSES ARE FROM THE PAST!

I am in complete agreement on 'Heat?' Pumps! The other thing you mentioned Heated Jackets. People these days seem to think that the house should be hot enough for just a t-shirt in the winter.

An air source heat pump will not work efficiently at extremely low temperatures. If it is the only heating source you have, it will switch over to resistance heating, which has a maximum COP of 1.0. A 100 amp service means you have a maximum of 200 - 240 KW of energy available. You would have to add up your maximum loads to see if the service is adequate for the heat pump in resistive heating mode.

We live in an old house in Sweden. When we moved in 20 years ago, it had a "combi furnace" for oil and wood, with an electric heating element. Because of the drastic increase in oil price, the old tennant only ran it on electricity. He had however also installed a hearth "casette" in the livingroom fireplace for cold winter days. The first year in the house we used 28000 kWh and also about 150 bags (about 3 cubic meters) of firewood. And we had a constant shortage of hot water. That’s when we installed our first converter. It was about 60% effective, but sadly it had to be replaced after 14 years. We are now four years into our second converter. It produces heat for the water radiators and also fills a large accumulator tank for our hot water needs. In the last four years, we have used between 13000 and 15000 kWh yearly. We have not burned a single log and we have never run out of hot water. Additionally, at 15000 kWh we were able to raise the indoor temperature to a comfortable 22 degrees C in the winter, from 20 before. In the warm season, when it only makes hot tap water, it uses less than 400 kWh per month. We are four people in the family. Unfortunately, with the current shortage of electricity, we have cut back to 19 degrees C last winter. But we are still very satisfied with the system. It saves 70% electricity or slightly better and pays for itself in 5-6 years. If we used firewood for the coldest weeks in winter, we could cut another 1500 kWh, but it's hardly worth the trouble.

Here in NZ we have used heat pumps for somewhat longer than UK. The main difference is we use them to heat air not water in radiators, they also function as air conditioning in summer. The key element is how we use the heatpump. It will quickly raise the air temperature in the house, but this quick heat uses more electricity, the secret to cheap use is to have the pump set at 20c on automatic, not rapid heat or other setting. Obviously one needs to have their house well insulated, roof and below floor, walls too if you can. Double glazing certainly makes a big difference too, but full length curtains and pelmets help a lot. We also have a modern immersion heater, these are far more efficient than the 20+ year old ones in many houses. You may be surprised but much of NZ (South Island, central North Island) have very cold winters. NZ has developed low emission wood burners, and we have one too, used in winter. NZ has developed over many years a very high renewable power grid, mostly hydo, but also geo-thermal and wind, and solar is growing. We built an off the grid house in a mountainous area, (Mackenzie Country) it was off the grid, and had central heating, not heat pump, run off a wood burner. We had a huge amount of our own firewood. The wood burner heated the radiator water, superbly, and hot water came from roof solar panel heaters. but the house was built for the heating system, with double glazing and appropriate insulation. It was very warm even at -15 C and buried in snow. We built for the situation. Back to heatpumps though, using our reliable electric supply we could easily in the urban areas have built a house just to be heated by heat pumps, with hot water coming from an immersion heater or solar hot water. The secret is to get organised and not continue destruction of the environment with oil and gas based energy systems.

You did not understand the video very well. He did explain the trick(electric heating the old fashion way is build in the heatpumps to trick the water temp up when it cannot heatpump it. And you mention it as if is something else when you buy a combined system. Hybrid system is just another name for the trick in the heatpump when it cannot work on outside warmth alone. What I again learn from the video is that you better spend all the money on isolating because when you are good enough isolated to have a heatpump working, then any heat source will use only very little energy. So maybe even the extreme cheap electric radiotor at the wall.

I live in Canada, have had two heat pumps since 2012 replacing base board electrical heat.. I do have good quality insulation and have experienced huge savings since then. No incentives were available and costs were paid back by 2018. No issues down to -20 as it doesn’t get any colder here. I do agree with the insulation comments. I would spend my money on insulation first, then on heating system.

Since UK electric is nearly 10 times the price of gas, that means a gas boiler costs ONE THIRD as much to run as a heat pump. . . I know, I fit them, then we come back in winter to 'upgrade' them with a gas boiler.

We just retrofitted our old early 1900's farm house with air-conditioning with the optional heat pumps. Two systems were installed, a spacewalk for the main floor, and a carrier system for the upstairs and attic. The house is 2300 sq feet plus a 400 sq fit attic, which was also included in the system. Previously, the home had hot water radiator heat and no AC. The boiler runs on natural gas. The boiler is 38 year old. The new system is designed to heat utilizing the heat pumps until the outside temperature gets down to 28 degrees. After that, the boiler kicks on. So far, with over a year of use, our highest monthly utility bill has been $118.00 US or both electric and gas. This is just over 1/3 or our previous high bills of 312.00. The system was very expensive to us, but having these ultra low bills, do help me appreciate the initial cost. I have zero complaints. Saving up now for a boiler replacement.

I have found it less expensive to run the heat pump down to around 10° F (the heat pump functions to -5°F ), it heats well but the output air is not as hot as the gas furnace (~ 95° vs 120°). Another plus with the heat pump is we now have central AC. I also have solar which offsets the cost.

When the other oil burner is replaced it'll be with a ground source heat pump and underfloor heating - even more efficient.

A good friend of mine with 45 year refrigeration experience told me that refrigeration and low cost don't come together when we were discussing air to water heating systems, I do believe him as any advise I received from him was always on the money.

The reason for the stressing of insulation is due to the differences in how heat pumps supply heating. The price difference between a 5KW gas boiler and a 10KW boiler is relatively small, but is significant in HPs, so the cost of initial install is much less if you can reduce your heating needs. If you ignore equipment costs, sure, just buy a massive 17KW HP for your cottage, but it makes more sense to insulate first whatever your heat source.

True...but that's far from being even as easy as easier said than done. I told my landlord that the winter before last would be the last winter I'd have an ugly wood pile outside of the workshop because I'd be insulating the building and putting propane heaters in. Well...I did a crap load of insulating but when it comes to something that had no insulation to begin with insulating it means a major construction project, tearing out drywall and such. The building I'm talking about has auto repair equipment all over the damn place! Just moving stuff to get ladders in there to insulate the ceiling is nearly impossible. And I'll tell you this, if you have one area that you simply can't thoroughly insulate, you're screwed! The cold air will suck up a crap load of propane and you'll be wishing the wood stove was back. I told him this winter I'd be heating with wood for as long as I live here and work here. If that's a problem, tell me know, I'll move out. He said, "can you put a tarp over it in the summer?" LOL I will still work at insulating but the next project that needs to happen is a small walk in door so that I don't loose so much heat when I open the overhead door to walk in. I'm still going to loose all my heat when the door opens though. So what's going to happen? I'll use both wood heat and natural gas but I refuse to use propane. It's FAR more expensive than natural gas which he uses in the house. Let me tie into the gas and I'd rip the stove out tomorrow! But "no, I don't want to do that" he says. You can't win! LOL

Greetings from Scandinavia, or Finland to be more precise. Thanks for pointing out the problem that the UK has with the houses (yes, I've been to the UK and witnessed it first hand..). It's not really a problem with the heat pump technology. I have now had an 8 kW air to water monoblock Fujitsu and radiators for about 5 years. It works just as I calculated. Enough down to about -12 C in my 130 m^2 house, below that I burn wood chips. The pump was about 3,5 ke and about 1 ke for installation (I did what I could, basically it was just the water pipes what the plumber did). It's installed on a separate concrete slab on rubber insulators below my kitchen window, if you are really quiet in the kitchen you can barely hear the fan running. Condensed water is run underground accompanied by a heating cable to avoid freezing. Yearly average temperature around here is about 5 C. Before the pump electricity consumption was about 10 000 kWh/year plus about 20 m^3 of wood chips for the winter. With the pump the electricity is the same, but I use about 0-5 m^3 of chips. That -12 C limit does not mean that the pump stops or anything, but after that the house starts getting colder. But still if it's -20 C during the night and -5 C during the day, the house stays perfectly warm. I didn't do this to save money, just to save chips and my time/labour. So far the pump has been pretty much start and forget and the house is nice and warm for most part of the year. Around -10 C the COP drops to around 2, but around 0 it's in the region of 3 without much optimization. In general I wouldn't jugde the pumps, you just have to know the limits and pick the right product for the right application, this is where most get it wrong. Sure you can't run 65 C water to the radiators at -20 C, but that kind of a house shouldn't have an air to water pump to begin with, an air to air on the other hand would help.

I love open fires, log burners and bonfires but I can see that all of these are in the future going to either be strictly controlled in the UK or stopped altogether. It can help massively if well seasoned wood is burnt, not that that has not been allowed to dry properly but I do not think sufficient controll over that can be achieved to reduce the risk.

Radiant heat is better than heat pumps in very cold weather but they are also very expensive. We have wood backup. I build a fire in a fireplace that has an insert when the temperature is below 40°. Can they put in a ventless propane heater to assist in very cold weather?

Insulate ceilings walls floors and windows first including draught-proofing. Putting any form of heating into a cold damp leaky box wont reap any sensible result. Common sense prevails.

I had a happy childhood. In winter my mother heated up the kitchen in the morning using a wood stove. And that was it. No heating anywhere else in the house. In summer the woodstove was taken out. Maybe 2 m3 for a winter? Family of 16 people. We had some trees in the garden, so actually no cost (as the trees grew back). Now Indonesia: no air-conditioning. no cost.

Top rant Roger. But please base your rant on the correct numbers. A COP of 1 or 2 is very very bad (did I say that's is very bad COP). You might get a COP of 1 at -20C. The average COP (or better Seasonal COP (SCOP), is around 3.4 to 4. So even at 0C, the COP of a good heat pump is > 3. Furthermore you are talking about Air-Water heat pumps. You forgot (the more expensive) Water-Water heatpump where the COP is quite stable because the energie is taken from the earth which is quite stable, even is it is The heat pump is certainly not a new technologie, it might be new technologie for the UK and is perfectly capable of heating a normally build house. Heat pumps rely on low temp radiators or floor heating and are doing a great job. But you need to understand how it works. A heat pump is the last thing you install in your house, after you got rid of the draft and the uninsulated floor, walls and most important the roof. Your rant should be about the uninformed installer (including yourself I'm afraid). Please get your fact right. p.s.

Disconcerting that you've got 19 upvotes so far. Quite a few people have clearly bought the hype, and are in for a nasty shock when they go ahead and install a heat pump. Air source heat pumps are expensive as it is, ground source heat pumps cost even more, and will be way out of most people's price range. Most UK housing stock is too draughty for heat pumps to work properly. Our houses actually have air bricks built into them to let outside air in and ensure there's adequate ventilation. Houses designed for heat pumps are completely draught proofed and don't have any built in ventilation, instead they use something called MVHR (mechanical ventilation with heat recovery) to exchange interior and external air without much heat loss. It's not feasible to draught proof existing housing stock to the level required for heat pumps to work efficiently. That's why people who have them installed are complaining of cold houses and large electricity bills. The COP of a heat pump depends on the outside temperature. Their COP drops substantially below 0C, and below about -10C most of them shut off altogether and switch to resistive heating (COP of 1, the heat you get out is the same as the electricity you put in). When it's colder you also need more heat of course, so what this means is that the electricity demand of these things spikes dramatically in cold weather. By what could easily be a factor of 10. Very cold weather doesn't happen that often in the UK so it might not seem like that big a deal, but if millions of households have converted to these things it's going to crash the grid. We have very little spare generating capacity as it is, there quite simply isn't enough spare capacity to support millions of air source heat pumps (especially if their demand climbs to 10x normal due to very cold weather). It'll be like the blackouts in Texas, except a regular occurrence every time there's cold weather. Vulnerable people will die, and housing stock will be ruined by pipe bursts. It's an insane policy, especially since most of our electricity is generated from gas with an efficiency of only about 50 percent, when modern gas boilers have an efficiency greater than 90 percent.

Heat pumps work in Canada down to around -30C. Even here it only occasionally gets that cold during a “cold snap”. Electricity is generated through emission-free hydroelectric power. People may be confused about heat pumps ability to perform in really cold environments but that’s most likely due to early take-up. The technology has vastly improved since then.

In Canada they don't make you get rid of your old heater, and almost nobody uses a boiler to heat their home. When the natural gas heat pumps become more common, I will consider one. Cost estimates are in Ontario you only save money with a heat pump vs natural gas it you can disconnect you gas service to stop paying the administrative fee. Even then it is only a few hundred a year. Not enough to ever pay for the investment. If you have a good southern wall, install a passive heat solar panel and you'll get an instant savings.

I have two air to air heat pumps fitted, an older Daikin and a newer Mitsubishi Ecocore. I also have undertile heating fitted throughout most of the house (the electric mat style not water pipes). When I bought the property eleven years ago the Daikin was the sole heat source for the property, and while it heated the air in the lounge and dining room, once you opened the door to the hall to get heat down to the bedrooms the lounge became quite cool. The second problem was that when you opened either of the doors (there are two ranchsliders in the lounge), all the heat seemed to disappear out the door, a problem when you have a cat. The other issues were the noise and dust. Now the undertile heating, rather like a radiator provides background heat that is silent and doesn't leave the house when the door is opened (no to the same extent at least), and heats the whole property. We rarely use the heat pump for heating, probably a couple of times a year only, but regularly run both for cooling, having one in the bedroom is the best thing we have done, and the Ecocore is quiet enough that you can sleep with it on. If I was still in the UK I would be maintaining my gas central heating but would look at adding a heatpump for the A/C element.

Hi Stuart, I am doing comparisons of ASHPs to gas boilers in existing homes for my university dissertation, would there be any chance you could complete my questionnaire when its ready? Thanks

When I visited the UK in 2018 my cousin was a gas engineer . Most of the houses I visited had gas boilers. The thing I noticed was that they heated the whole house. Nice and lovely and warm in the house. Cost of gas in UK about 1/4 of Electricity in UK. Yes I can see why installing what you call an air heat pump (which in fact is an air to water heat pump) is not a great idea. Recently in Australia I installed a mini split Fujitsu. It uses DC inverter technology and even flat out it is very quiet both inside and outside. Coat of unit plus install was $3000 Australian dollars which is about 1500 Pounds UK. Ok first why heat the whole house ? When I was a lad in the UK you heated the house with a coal fired Kitchen range. Sure only two rooms would be warm and the bedrooms would be cold. So first don't try and heat the whole house. Second you are talking about air to water heat pumps . They involve much more complex copper pipe work and radiators. So why not install say two or 3 Mini splits Air to Air heat pumps. These new DC inverter units ramp up and down automatically also they have infra red detectors, so they go into low mode when people are not in the room. One thing we have done in Australia and I bet this happens in the UK is that all energy companies are charging the same price per MWhr no matter what their energy source is. Oh of course one great thing about the Mini Splits is they will cool very effectively and as you guys in the UK have found out you are now getting very hot summers. I love your passion and accent but realise their is no easy solution to any heating and cooling situation it must be engineered very carefully.

I agree. Where are HVAC or ductless heat pumps used to heat water storage tanks? I have never heard of that before. It certainly would not be efficient - even a straight resistance heater for the water tank would be better.

That heat jacket is really a good idea. I work in my house with a heated chair with room temperatures at about 15 degrees. Sometimes my fingers get stiff because of the cold though, and I cannot play guitar or type quickly. The greenest solution for your house is always isolation and elimination of heat losses. You can lend or buy a heat camera and make a heat picture of your house when it is cold to get the places where you prioritize your efforts in this. You are completely right about heat pumps, when the outside temperature drops the gain in efficiency of heat pumping compared to an direct electric resistance heater becomes negligible. And power from coal and gas from your grid supplier is made wide 40% efficiency so when coal or gas is burned you need at least an effiency factor of 2.5 to have an ecological gain , that is not in deep winter temperatures. Where all the electric power would come from in a huge winter is not yet solved, as in pure winter there is little sun and sometimes even wind can not deliver when the blades on the sea or land wind parks are frozen with ice deposits. Just one "terrible"winter will change the minds of the greenies that think this is a solution. The damage of a power outage in such a winter water systems will be huge all over the projects that use this technology,:frozen houses, sewer systems, leaking pipes,cracks in the wall, with additional poor people frozen to death inside their home ,or sick because of the cold. It is not even a matter of economics , that can be for personal decision-making be covered up by subsidies, it is pure technical energy input -output calculation that makes this a very bad idea, as the investment in energy and raw materials could be nearly as high or bigger than the gain. To begin with, CO2 is not the devil's gas, it is on the contrary, an essential food for plants that is good for the earth and that have in geological past times always fluctuated and that is now very scare at 1 in 2500 molecuels in the air. CO2 as driver of temperature change is fake science. So the whole presumption of the gov on CO2 is just BS to begin with. The gov claims that it is science , but it is croony science, only there for opportunistic causes: modern Lysenko-ism. This heat pump plan belongs in the waste bucket as many more "green" plans like electric cars, bio energy, abandonment of nuclear energy, nitrogen fertilization limits. The EU is still on this path until the European economy is not there anymore. Germany will topple over and will be poor and hungry the next generation as they were the most fanatic in green policies. Green stands for hypocrisy, dumb ideas and corruption.

Been living in Paris region of France since 1999. Back around 2005 long before the current trend for heat pumps we were convinced to install one along with a lot of neighbouring by a door to door salesman. Supposedly from EDF (Electricity de France). It had the classic box outside & one defuser on the wall above the kitchen door. It was sold on the basis that this was what shops had over their entrance doors. You remember when you used to go into the supermarket & walk through a wall of hot air. As many houses in France our house was heated with electric radiator. Very dry heat. This because France has 50 plus nuclear power stations to give it an historical energy independence from the bigger oil producing nations. It also Hy we have a very good electric train network including the TGV. Just the heat pump box cost us 10k€. The subversion scam was setup differently. It was a long term loan. So the heat pump was deemed to reduce your electricity consumption but instead of reducing you bill the savings went to paying off a long term loan for the pump. The installation was done by cowboys we us having to make good the mess. The fans became noicey. You had to leave doors open around the house for the heat to circulate. Then when we came to move house a couple of years later the long term loan was still years from paying off. Something that you could hope to pass onto the buyer. So essentially the new owners got what ever small benefit there was to be had from the hear pump & even that was debatable & we continued paying off the loan for nearly 10 years after moving. Any loan is an issue in France as everything is taken into account by the banks when applying for a mortgage. If ever there was a case for be miss sold something this is it. The home where we had it had these electric radiators in every room, a wood burning stove (insert) in the living room & a large immersion heater fir hot water (very common in France). All continued to be used. The house was mid terrace from the 8O's so concrete block walls with polystyrene foam backed plasterboard lined walls & fairly good Rockwall loft insulation. We now live in a 300 plus year old house with meter thick stone walls & no insulation. Gas combi boiler & cast iron radiators doing it all. Gas pipes were being installed everywhere until ver recently. We have popup cowboy firms busily lining or externally cladding people's homes with flammable foam insulation for 1€ basically financed by France's big oil companies like Total to offset there continued solution. Bought a diesel car because we we encouraged to do so that soon won't be able to drive into Paris & Ill be forth nought. All a bit crap all this. People want to do the right thing but it's all a massive scam that could bankrupt ordinary people & leave them with no proper heating. Only going to excelerate now to avoid Russian gas.

Ive been running this system for 7 years now, and its really cheap to run, and cheap and quick to install with zero maintenance, This combined with a few cheap roof mounted grid tie microinverter solar panels is the holy grail, every home should be changing over to this. Using air to water in a retrofit to heat an old house is as roger said a very bad idea. There is really really poor understanding of heat pumps in this country,

They can have a central thermostat but I simply have an on /off switch for each one ...and I do heat one room at a time for economy . Theres no point in running heating in a bathroom all day if you are not in there but wait until you intend to take a bath ! The kitchen warms up quickly with the oven on as well ..but I will run the rads in these rooms when it has really cold snap. The upstairs bedrooms are only used for sleep and I can put an electric heater on for 5 minutes if its very cold before bed and with an electric blanket or HW bottle you are set come bedtime.(It is also healthier for you to not sleep in such dried out atmospheres all the time which also encourage bugs to breed and moths to also breed among your woollens ) I wear more clothes indoors as well ..not sitting around in T shirts in Winter..but wearing woollens and long johns ... after all I live in Scotland..on the Isle of Arran .

They are going hard to install heat pumps in New York. How much heat do you absorb when the outside air temperature is -18 degrees C or lower in the middle of a New York winter? I asked a HVAC mechanic today about how this is supposed to work when you have a problem in the middle of winter. With an oil furnace it does not take too much skill to change a nozzle or filter. A few spanners and the job is done. They told me that they had to call technical support sometimes to repair these heat pumps. One time he was on hold for 6 hours trying to get information.

Most HVAC mechanics I know don't have a clue about relative costs or equipment efficiency. Many don't even know what the COP rating means - they just install the equipment where they are told to install it - or use a rote procedure to do any repairs. With a gas furnace, you do not need all the power that an oil fired furnace requires for its injector pump. If you had to, you could run a gas fired HVAC system off your car battery by running the car for 10 - 15 minutes every hour or two.

Very well said. Combining heat pumps with radiators instead of underfloor heating is a not an efficient solution since even the best heat pump cannot provide more than 60 Celsius. A heat radiator requires 75- 80 Celsius to provide max efficiency. You can add a DC electric heat element inside a hot water cylinder and combine it with a solar panel.

If you want maximum efficiency from a heat pump, forced air would be a better idea (like a mini split). They also work at lower temps compared to radiators.

I live in Massachusetts and my old house that was built when fuel was cheap. I added a layer of insulation in the attic and reduced my fuel cost by only about 10%. I then replaced the air conditioners with heat pumps and left the fuel system in place as a backup in case the outside temp fell below -15°C. After this, paid only 15% of the cost in electric that I usually paid in fuel in all my years before. I was so pleased with the system that my new home has 10 zones from a heat pump system. Yes, the new house is very well insulated, and I can heat all 6600+ sq ft of it with less than 50kBTUs, so the heat pumps are ideal. Maybe things here in the USA are different, but the heat pumps here are great. They do save money. Many of the issues you cite do not happen here. For one, the systems are not that noisy and the fans don’t get louder over time. The comment on gas systems is correct in that they are getting very efficient. However, even if the gas system is 100% efficient, the heat pump uses 75+% less energy. So, if the cost of energy in electricity in the UK is more than four times the energy in natural gas, then yes the gas system is a better choice. But for my money, the little noise coming from the heat pump is better than the smell of burnt gas.

We install heat pumps only in well insulated houses. I have a house in Belgium, well insulated, I have a swedish geothermal heating pump and floor heating. A house in the Ardens 250m². 18 b 9m on two floors.Average electricity consumption 7250KW/year. Full installation for the full house was 13 years ago was 28000€ My Solarpanels produce 12000KW/year so I sell 4 to 5000KW back to my energyprovioder. Bottomline: Heating pumps work very well in good conditions. In Belgium we install a lot of heatpumps in combination with a good insulation and a clean boiler (so no legionella) Important is that you work with a company that specializes in heatpumps.

I replaced the old oil boiler with a heat pump about a year ago. For context, yes I live in Scandinavia, but the house is quite large, no forced air circulation, no AC, and it was built in the 70's. Over the years we have added insulation to the roof (significant reduction in oil consumption), replaced doors and some windows (again, significant reduction in oil consumption) and as is the norm around here, all windows are double pane and at each enterance there is a small mud room you have to go through (front door - small mud room [1-10m^2] - regular door). To be clear, those relatively inexpensive improvements have reduced the fuel consumption by about 50-60%. While the insulation in the walls does not meet the current building codes, adding more would be difficult, expencive and require us to install a forced air circulation system. About the current heating system: For winter, we expect about one month of average temperatures being around -10C, and about one week avg. between -15C and -20C, peaking around -30C. For summer we expect avg. temperature of around 20C for 2 months, peaking at around 30C. Due to cold winter, we decided to burry about 1km of pipe, about 1,5 meters deep on a nearby field, so the sun gradually heats up the clay soil in the field over the summer, and that energy is slowly transferred to the house during the winter. Indoor temps stay at or above 21C through out the year (lowered to 20 or 19C during the winter if electricity is ludacrously expensive). There is constantly hot water, and it won't run out even if multiple people take a shower in turns. Heat pump COP at it's worst (late winter when the field is at it's coldest and it's still -10 to -15C outside) has been 3,5 and during the summer when it's more or less only heating hot water, the COP has hovered around 4,8. For me, COP of 3 sounds horrible, but maybe that is the land of air-source heat pumps. What difference has there been since switching from oil to heat pump? The hot water temp. got lowered by few degrees C (just hot enough to keep legionella out), which was a noticable difference. There is still hot water, it's just slightly less hot. Very different from a district heating system where the temp in the heat exchanger is well over 90C. Apart from that, there hasn't been a difference (well, we no longer need to order more oil once a year). Is it worth it? The timing was not great, as right after the installation the cost of electricity increased by 600% for the winter, but in the long run it's probably worth it even if we continue to see occational high electricity prices. Could it be made more efficient? Yes. The system would be much more efficient if we had water based floor heating. Is it worth it for this house? Not really. Maybe if there was major renovations, but there shouldn't be any for at least 10-15 years.

How good the insulation is does not affect the efficiency of heat pump.

Person from Scandinavia here. We have had heat pumps as the de-facto standard heating option for 10-15 years in Scandinavia, which means that almost all houses nowdays run on heat pumps. People are happy with them, and they work well and are cost efficient. So I don’t undestand the argument with low temperatures and bad efficiency in the UK - we only have such a problem during the coldest winter days that never happen in the UK . With respect to the tap water, it is just simply a imagenative problem that you can’t combine energy efficient tap water, comfort and legionella-safe. Come visit us here in Scandinavia and you’ll see. I fully acknowledge that British houses are not well insulated, but that means that A) houses shall be insulated B) the heat pump needs to be of greater dimension.

Your country (assuming Sweden) generally has an overall yearly lower temperature than us in the UK and you have designed and build property (and indeed your infrastructure) to cope with it.. We are not so organised here and any extreme weather tends to flummox us and everything shuts down.. Also, UK houses dont tend to have suitable places to mount the main pump box and the fan can be surprisingly noisy. I think newbuilds are best suited to benefit from Heatpump tech where the property layout can be re-designed.. Alternatively , put it in the bike shed that we were forced to build..
