There are quite a number of ground source heat pump installations in the county using the trench system rather than a borehole. A near neighbour is very impressed with it - it was installed at build ten years ago and the floor is nice and warm. The council installed air source heat pump systems in outlying village council houses some years ago now but I hear it is expensive to run - the units are 18Kw. All stone built properties in the north can apply for free external cladding (paid for by the electricity companies) and many have taken it up but it is very fragile - rendering over 100mm insulating foam..
I have been pondering doing a DIY job - making a 10 sq/meter slab of concrete, painted mat black, contained within a heavily insulated “box” and covered with 1sq/meter double glazing panels (which I have handy) . The thing is, do I make 50mm air passages in the concrete for a “hot air” system or incorporate copper tubing in it for hot water. I have plenty of room, facing south for a curved array even. What prompted me was how hot the dashboard of the car gets when sitting in the sun. What do they say - heat capture can be 1Kw per sq/ meter..
By the way - I hadn’t intended to put the solar panels on the roof, but mounted about 5ft off the deck on a central column to make it sun following and easy to clean, or brush snow off it.
I’m interested in this heat exchange tube thingy - could we get a piccy per chance ?
Antagonise no man, for you never know the hour when you may have need of him.
