How does the efficiency of electric heat pumps compare to traditional heating methods?

Electric heat pumps are more efficient than traditional heating methods because they utilize a principle known as heat transfer, which allows them to move heat rather than generate it from scratch. This ability enables them to achieve efficiencies ranging from 200% to 300%, meaning that for every unit of electricity consumed, they can deliver two to three units of heat energy. This high efficiency is a result of the heat pump extracting heat from the air, ground, or water and transferring it indoors, effectively making use of existing thermal energy.

In contrast, traditional heating methods, such as electric resistance heating, convert electrical energy directly into heat energy at an efficiency of around 100%. While gas heaters operate with varying efficiency levels, electric heat pumps have the advantage of the heat transfer process, distinguishing them as a more energy-efficient heating solution. This efficiency is especially beneficial in climates where heat pumps can operate effectively, providing significant energy savings over their life cycle.
