What Is Heat Pump?
A plain-English explanation of Heat Pump — what it means, how it works, and why it matters for your home energy.
Definition
A device that moves heat from outside air or ground into your home, using electricity
Heat Pump Explained
A heat pump is a heating system that extracts thermal energy from outdoor air (air source) or the ground (ground source) and transfers it inside your home at a much higher temperature. Because it moves heat rather than generating it, heat pumps deliver 3-4 units of heat per unit of electricity consumed.
How Heat Pump Works
- 1. Refrigerant absorbs heat from outside air at low temperature
- 2. A compressor increases the refrigerant pressure raising its temperature
- 3. Hot refrigerant passes through a heat exchanger warming your home's water circuit
- 4. Cooled refrigerant expands and the cycle repeats
