Hi PC,
Just wondering what the con is re ground sourced heat pumps. We have a
couple of air sourced ones, one of them around the 10year old mark and it
struggles a bit when it's cold outside and it also has to pause to deice
itself in  the 0 - 5C area.. Ground sourced would appear to be free of both
these effects - but maybe have other issues??
