See my post over in the heat pump geothermal thread. Problem with using a heat pump is speed control to ensure all of your excess generated power is being used without importing from the grid. Not an easy thing with current available heat pumps. The technology is there used in mini splits to modulate output to temperature but there seems to be no simple way to modulate to avalible power.
