Hi all, I am from Eastern Ontario and only just found your forum. My interest lies in lowering my heating oil consumption - around 475 liters per month by possibly looking at GSHP or similar.
Not sure about digging up my backyard and it's probably too small anyway but about 30 years ago I read an article in the Mother Earth News titled " The Biggest Ice Cube in Captivity". If I recall correctly a heat pump was connected to a very large tank of water....the coils were inside the tank and the system was used as a heating system in winter which effectively turned the water to ice and an air conditioner in summer to turn the ice back to water ready for winter. Obviously not perfectly balanced but could be augmented with solar collectors etc to start the system with higher temps.
The water tank was in his basement but reported that it could be outside in a building the size of a small garage.
Hope this isn't too long of a Hello
