Has anybody got experience with heating a house with ice via a heat exchanger.
I think it could be an interesting way of storing the excess PV-Kwh produced during sunny days for the winter, seeing the export is a mere 3.1 Pence and once smart meters are installed one might get stung for exporting in excess of 50% with a hefty tax bill.
I've seen something like a large underground storage tank which is filled with water and has a coil of plastic pipe in it which is connected to a heat exchanger.
This draws the heat out of the water till it freezes and beyond, heating the house. Then in the summer months the tank is unthored by reversing the heat exchanger, which then could also cool the house.
Sound plausible to me, just don't know how big it would have to be.
