MDV Heat pumps are suitable for almost all types of buildings - from private homes to large office complexes. Once installed, good heat pumps are virtually maintenance-free. As a result, and due to the energy costs saved, the purchase of a heat pump usually pays for itself within a short time. Heat pumps work on the same principle as a refrigerator, only in reverse. They extract heat from their environment and release it downstream to the building's radiators. This allows you to reduce the supply of external energy or even save it altogether.
