Both air-to-air and air-to-water heat pumps require electricity but are still much more efficient than conventional heating systems.
Using condensers, heat exchangers and refrigerants, we can use heat pumps to produce much more heat than electricity.
A heat pump's coefficient of performance (COP) measures the heat pump's efficiency.
In general, air-to-water heat pumps have a coefficient of performance of about three, producing three calories of heat for every kWh of electricity consumed.
The COP varies with the outdoor temperature. Efficiency decreases when the weather is very chilly. However, air-source heat pumps perform well throughout the year and are popular in cold climates, including Scandinavia.
To make the best use of a heat pump, you must have your house well insulated, and the unit size should be suitable for your property. If you install a heat pump properly, it will help reduce your energy bills and carbon footprint.
