ASHP costs

swinter

Hi all,
I live in a village with no gas and currently have storage heaters. I have been looking at the ASHP systems and was just wondering how much they cost installed. I know there are a lot of factors but was looking at a split system with a heater in the front room and one at the top of the landing. Was looking at the mitsubs. Just a rough ballpark figure.
Many Thanks

I would estimate 2 wall mounted units on a 2 way multi split would, all in, cost about £3000, for decent quality kit, that would be for 2 x 3.5 kW uniits, however, it all depends on length of pipe run, mains supply,and if 3.5 kw is adequate for the room sizes. you say top landing, are you hoping this will heat several areas?, if so, thats not necessarily going to work, if theres a roof void you might be better off with a ducted system, with ducting into each room, again this would have to be sized correctly are would no doubt affect the cost.

My system sounds remarkably similar to what you're proposing

This cost £2400 inc vat installed
It works extremely well in my particular situation, averaging £1 a day to run over the last 3 months.

Having a 6.3kW Fujitsu Invertor Heat Pump installed in a large south facing conservatory for £1550 including the 5% VAT. However, the main electrical supply to the outside unit will be provided as part of the conservatory works.

If you want an air-to-water system, i.e., so that you can use normal radiators, then for a good quality system, you are looking at £4-5k for the HP and thermal store, plus the cost of the radiators and pipes (£1k) and the installation costs (£1-2k), unless you install yourself, which you can do with an air-to-water system as you don't have to go near any refrigerant. You can get systems for half that cost, but have higher minimum guaranteed operating temperatures, higher noise outputs and less power output.

However, if you live in a village and have a reasonable sized garden, and don't mind some disruption to it, then I would go for a ground source heat pump, slightly more expensive to buy/install, but no noise issues and cheaper to run.

Are these ASHP (air to water) eligible for grant aid from the government:

If I need to supply:
underfloor heating
rads
baths

will I also need an additional heating element to boost the supply of heat to 60 or 65 degrees?

Many thanks

you can get a grant for £900 but you have to get an accredited MSC installer to fit it for you, but they will more than likely add £900 to the bill anyway, so NO saving there, I couldn't get my grant because the installer I used was not MSC, but then again he is a friend so did not load the price. but yes very efficient system...if fitted right.

I agree with Albyota, in that you can get grants, but the premium charged by 'officially registered installers' normally offsets the grants. I think many of these systems are only 5% VAT now though, so might be worth checking that it is in then 5% bracket.
