We have a 1860 solid stone cottage, approx 50m2 ground floor and same on 1st. looking to convert to attic for extra space. The Oil boiler was installed 2 years ago, with some new rads, double glazing throughout. no gas supply and we are installing a wood burner for some extra sitting rooms cosyness.
we plan to remove the oil boiler and replace with renewables. I like the idea of ground source heat pumps (GSHP) and Solar thermal panels, even the newer PVT panels for combined electrical generation.
Our builder commented that a friend of his had problems with GSHP in the winter when the temp dropped and i am concerned that such a system would not cope in the harsh weather with little sunlight.
are there systems or installations which overcome this issue and how ?
