In 2020, I purchased an 1870s home with an old electric storage heating system. I had two options: upgrade the storage heaters or look at an air source heat pump. I went with an air source heat pump for a few reasons:
- Cheaper running costs than a storage heating system.
- Removing heaters from my walls freed up wall space, replacing them with underfloor heating.
- I had little opportunity for insulation as the walls are very thick stone. External wall insulation was not suitable as I live in a conservation area and internal wall insulation would take up too much space. There’s an apartment above me, so no loft to insulate. Floor insulation in suspended timber floors was the most reasonable option to improve insulation (and shared costs with underfloor heating system).
