How it works

Have you ever wondered how a ground source, exhaust air or air heat pump actually works, or what the difference is between an air/water heat pump and an air/air heat pump? We give you the answers you need, so you can make the best choice for you and your home.

Ground source heating

Ground source heating is pure solar energy that's stored in the ground. As the sun begins to shine more strongly in the spring, energy is stored, little by little, beneath the surface of the ground. As time goes on, the amount of solar energy increases and the energy is stored lower down in the ground. The heat pump concentrates the stored heat energy, enabling it to heat water for your showers and radiators.

Air/water

Have you ever wondered how air can be used to heat your home? An air/water heat pump can concentrate the heat energy in the outdoor air to such an extent that it can be used to heat water for your showers and radiators.

Exhaust air

Exhaust air heat pumps first ventilate your home and then use the heat energy in the ventilation air to heat your water and your home. In other words, an exhaust air heat pump reuses energy from waste air.

Air/air

An air/air heat pump is ideal for properties that use direct electricity rather than a water-based heating system. An air/air heat pump reduces your heating bills and acts as an energy-saving add-on to your primary heating system.
