Colmac HPA4 Heat Pump system for 2 low-rise two story buildings.
Three 120 gallon electric solar tanks for storage and backup heat
Two Rheem Hybrid heat pump water heaters reheat the recirculated water from the building.
The Colmac heat pump is a ''One Pass'' system that heats the water from cold (74 degrees) to hot (125 degrees) in one pass. It won't heat the recirculated hot water so the hybrids were added to do that
