Not all heat pumps are created equal

WP Arten

There are three types of heat pumps: air source, ground source and water source. The operating principle is the same for all three. Heat pumps differ only in where they get their heating energy from. Which heat pump makes the most sense for your home not only depends on the financial aspects, but also on the technical and structural options.
