Pro's and cons of a heat pump

Hi Guys.  

My son is in the process of buying his first house.  There are currently night storage heaters in there. Most are older models. One is quite modern.  There is currently no gas at the property but there is in the road if he wants to get it put in.

We are looking at options of either getting an Air sourced heat pump put in with new radiators etc or getting gas put in and going down the gas boiler route.

Does anyone have real world experience with heat pumps re running costs against the cost of using gas. I seem to remember that you need bigger radiators ? I may be getting that confused with something else :)

There is the obvious saving of standing charges if he doesn't get gas put in. Other than that I know very little about heat pumps. I am aware that there are currently grants available for heat pumps. 

Does anyone have any first hand experience or recommendations please.

Thank you

Gary

  • My gas boiler broke down last year and I installed a heat pump to replace it. I don't have a full year's figures yet to compare, but it's looking like it working out somewhat cheaper than the gas - more so when you add in the lack of gas standing charges.

    However - I do have underfloor heating throughout and a large thermal store - so the heat pump can run at about 35 degrees for space heating and make the most of off-peak tariffs (I've got one that runs 0500-0900 and 1300-1600). On the domestic hot water side (hot tap water) it's significantly less efficient having to produce at 55 degrees (and due to having loads of thermal insulation DHW is probably a larger proportion than for many). Still it seems to work well.
