Heat Pumps

Air-sourced heat pumps absorb heat from air and transfer it to heat water. They run on electricity but are roughly three times more efficient than conventional electric water heaters, so when used in the right environment they save energy, save money and reduce greenhouse gas emissions. Heat pumps work on the same principle as your refrigerator, but instead of pumping heat out of the fridge to keep it cool, they pump heat into water. Electricity is used to pump a refrigerant around the system, which picks up heat from the air and transfers it to the water.
