BRES uses heat pumps for heating and cooling. Heat pumps are more energy efficient than other heating systems (particularly resistance electric, the other electric heat source), they don’t require separate systems for heating and cooling, and they don’t rely on gas or oil which are increasingly more expensive. Where possible we use geothermal heat pumps as opposed to air source heat pumps. Water comes out of the earth at about 55 degrees and the geothermal heat pump takes advantage of this constant moderate temperature to heat and cool.
We also heat water using a heat pump. Heat pump water heaters use air from the house instead of resistance electric to heat the home’s water. In total, it is about three times as efficient as a resistance heater.
