What makes Calitec different?

20 year guaranteed stainless steel
hot water cylinder

Hot water heat pump systems are a sustainable way of heating your water by extracting ambient free energy from the atmosphere.

It works on the same principle as an air conditioner or a refrigerator, extracting ambient free energy from the atmosphere and transferring it into the refrigerant gas. This gas is compressed to a liquid in the heating coil inside the stainless steel hot water cylinder which creates energy and heats the water.
