The home’s oil-fired hot air furnace was removed and replaced with a new energy efficient heat pump that was connected to the existing ductwork. The ductwork was modified to better balance the system operation. The PV system will offset the electricity required to operate the heat pump. During the heating season, the solar thermal system helps supplement the heat pump to decrease the heating cycles and electricity used, sending solar-heated water to a hydronic heating unit located in the basement.
