Geologic Heating Systems supplies a range of Direct Expansion (DX) heat pump technologies that are suitable for geology that is dominated by rocks. These heat pumps require little or no annual maintenance and repair. Designed without a chimney, these environmentally friendly heat pumps do not give out any greenhouse gases.
A specialty of the DX heat pump from Geologic Heating Systems is that its operation does not involve high temperatures or flames. This type of heat pump is suitable for homes as it does not create any noise or disturbance that is otherwise created by conventional fans or air conditioning systems. The heat pump receives maximum energy as copper is used to connect their energy transference medium to the earth. Designed without a circulating pump, this DX heat pump is able to cut down on electricity costs considerably. As this heat pump only has a single sealed energy transference circuit, regular maintenance and repair does not need to be undertaken.
The DX heat pump, supplied by Geologic Heating Systems, can be installed in areas dominated by rocks as well as in locations where there is minimal space. The vertical system required for its installation can be used in 3 inch bore holes, drilled into the earth.
