A heating system for a building having solar panels for collecting solar heat including sunlight concentrating lenses and a heat storage chamber for storing excess solar heat is disclosed. A heat pump is provided to supplement the solar heat when the temperature in the heat storage chamber is below a comfortable level. During heat pump operation, solar warmed air is pumped from the heat storage chamber to a chamber surrounding a heat pump evaporator to raise the evaporator ambient temperature and provide more efficient heat pump operation.
