Replacing Storage Heaters with a Heat Pump in a Stone Cottage

Paul1098 · 2026-09-27T20:22:39Z

Hi Mars,Just at the start of my Renewable journey and watched a couple of your Youtube videos on Heat pumps and Installers.I'm not surprised that people struggle to find a decent installer for heat pumps as we have struggled to get a decent installer for a new oil boiler in the recent past and some have even struggled to service it.Looking to use the BUS to replace old storage heaters with a heat pump in an stone cottage - another complication being it's in a national park with Article 4 restrictions but hopefully rear back yard is OK.I'm OK with heat loss calcs and pipe sizing for normal high temp heating systems but can imagine the low temps involved with heat pumps cause a few extra problems.

If I can get a system installed for no more than £4k plus BUS then I'll go for it. If that turns out to be unrealistic then I'll not bother.

Given that you are starting from scratch I think you are unlikely to achieve this unless you are lucky, do some gymnastics with the contracting, or do some work yourself.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
