The Earth is warmed by the sun. Ground or water source heat pumps can harvest this energy from the ground, or bodies of water, and use it for heating and hot water. The most efficient choice, where space allows, for both domestic and commercial applications.
Air source heat pumps harvest the sun’s thermal energy from the air. Ideal where space is at a premium, and economic to install, they can provide energy for heating and hot water in domestic or commercial settings.
