Ground-to-Water Heat Pumps

Ground-to-water heat pumps extract heat from deep boreholes or from surface ground collectors. They are installed inside the house and connected to the ground manifold via two pipes. Their main advantage is consistent output and heating factor even in severe freezing conditions.
Heat pumps on/off must be supplemented with a storage tank and a hot water tank or a combined storage tank that serves both for heating and hot water production.
