How does a heat pump work? How can it make heat when it is so cold outside?
A. Almost every household in America has a heat pump. A refrigerator is a heat pump. The “warm” air in a freezer is absorbed into the refrigerant and moved to a heat exchanger outside of the refrigerator box where a fan blows across it and cools the refrigerant off. The warm air you feel coming from under the refrigerator is the heat that was transferred (pumped) from the freezer.
