The older part of the house is seventeenth century, and a 2013 addition,

We have an 11kw Ground Source Heat Pump, underfloor heating downstairs, radiators (large surface area) upstairs..

A 4kw Solar PV roof is set into the roof for minimum visual impact. We also have a 38 v solar immersion in the hot water cylinder, in addition to a mains one, this enables the roof to heat the cylinder directly when there is surplus production of electricity. This is all automatically controlled.

I am looking at a Tesla battery backup system, which will provide power to the house at night and when there is a power cut, which is often in this windy, top of a hill village of Holwell
