I have been looking at replacing our town gas supplied boiler with a heat pump. I read that heat pumps will get water to 54c and since it is recommended to heat water to 60c to eliminate Legionella they recommend installing a supplementary immersion heater and running once a week for 1hour. Engie have quoted me 18000€ to supply and install. This seems excessive to me

Engie have quoted me 18000€ to supply and install. This seems excessive to me I was quoted 12500€ three years ago. I was entitled to 3500€ gr@nets which helped. The system works very well and it’s clean and not smelly compared to the old oil fired system. Shop around for quotes. I asked for three which were all within 900€ of each other.

Heat pumps rely on many factors, make sure you do all your research, large, badly insulated houses do not cope well, also the installed rads may not be efficient enough, i looked into it in the UK and decided against for now.......i feared it would not warm the house sufficiently and also cost me 15K. Many people will want to sell you it, but will it work?

Are you just useing the pump to heat DHW? if so this is very expensive, I have used Engie but will not ever again, they send out third party fitters, I had two bad ones, need two returns to correct things that should have been installed in the beginning, so would not recommend them. My DHW is set at 50C, but its a sealed system and the small amount that is stored is at an higher temp.

Many people will want to sell you it, but will it work? I agree with JD, the figures just didn't add up and the snake oil salesmen will tell you anything to get you signed up. Although, we have friends here in Brittany who have a very large stone longere (long house) and they have it to do their heating. It is a five bed house with pretty good insulation and they are using their existing radiators, it cost 18000€ (Ariston) and they seem very happy with it. The hot water is from the existing ballon as they were worried about the water not being hot enough.

If it's just for hot water, that's a ridiculous price. As JD says, if it's to supply heating as well, you need to take into account how well insulated the house is and how the heat is distributed. The ideal is underfloor heating. Our gas/water geothermal HP provides hot water via a 200l ballon. That's got the option to heat independently of the HP but the only time we ever needed that was during a prolonged power cut when it didn't work anyway (obviously) ![:D](//storage.proboards.com/forum/images/smiley/grin.png) No complaints about the temperature of the water and no illness 14 years on...

Heat pumps aren’t for everyone. The construction characteristics of the property will determine if an HP is practical or not. My place is from 1980 with good insulation and double glazing etc. It works perfectly here though I’ve owned properties where HP would have been out of the question. Get advice from recommended local companies.

It’s a modern house with underfloor heating and it is for heating as well as hot water

Then it's a no brainer. Don't forget about maprimrenov. We are getting 9000€ off our installation (already had 5000, 4000 to come).18000 seems high, ours was less than 14000.

Have those of you who’ve had them installed had to have new radiators installed please? We’re thinking of having a heat pump installed but having to have larger radiators installed is a step too far.

Used existing radiators here. The installer said that we might need to add another radiator in a hallway to ‘balance the system’ as he put it but all worked perfectly when the system was up and running. Really impressed with the efficiency Re electricity consumption. The only thing I 2as worried @bout was the noise as the outside gubbins is not far from our bedroom window but the noise is minimal and not a problem.

We have a heat pump water balon which is linked to the VMC in our well insulated house. It gives us a constant supply of hot water for the third of the cost of our electric only balon in our previous house. Also have a heat pump tumble dryer which is very economical to use.
The fossil fuel industry is seems to be behind most of the bad press about heat pumps. I think they should be installed in some form in all new builds.

Bear in mind that you need some form of back-up in case of power cuts or really prolonged bad weather, rabbit, if you don't have a woodburner. We've only experienced one ten-day spell of day/night sub-zero temps but by the end of it the HP was struggling to get the house up to 16C and drawing heavily on the grid.
