Comparing air-to-water versus ductless heat pump systems

I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems.

Switching heat pumps between domestic water heating and cooling

Air-to-water heat pumps and water-to-water geothermal heat pumps provide warm water for space heating, domestic water heating, and chilled water for cooling. Switching a hydronic heat pump system from space heating to cooling and vice versa seasonally is relatively simple. The system operating mode is changed at the thermostat or a dedicated system mode switch with heat, off, and cool settings.
