When it comes to comparing hot water heating solutions it’s hard to go past heat pump transfer technology.

Hot water heat pumps have been endorsed as one of the most effective forms of heating water by government agencies, such as (EECA) Energy Efficiency and Conservation Authority.

Heat pump systems are often the simplest replacement for an existing electric hot water cylinder.
