This Clitech geothermal heat pump CWR is applicable for different installation conditions of deep underground water system, shallow ground water system and water pipe laying in soil system.
Higher efficiencies are achieved with CWR geothermal heat pumps, which transfer heat between your house and the ground or a nearby water source. Although it cost more to install, but it has low operating costs as it take advantage of relatively constant ground water temperatures, moreover, it can be used in very extreme climatic conditions than air-source heat pumps, and clients satisfied with this system very well.
