Can a GSHP provide both space heating and cooling for my home? And what about heating hot water?
Yes. A Ground Source Heat Pump (GSHP) can be a combination heating/cooling and hot water heating system. You can change from one mode to another with a simple flick on your indoor thermostat. Using a desuperheater, some GSHPs can save you up to 50% on your water-heating bill by preheating tank water.
