Hot water heat pumps work by extracting heat from the surrounding air and transferring it to water, rather than generating heat directly.
A fan draws air into the heat pumps evaporator
which contains a refrigerant that absorbs heat from the air, turning it from a liquid to a gas.
The refrigerant gas is then compressed, raising its temperature significantly. The hot, compressed refrigerant passes through a condenser coil, where it transfers its heat to water storage tank, heating the water.
Heat pumps are more energy-efficient than traditional gas or electric water heaters because they use electricity to move heat rather than directly generating it, leading to lower running and reduced greenhouse emissions.
