Savant Solar designs and installs geothermal heating systems. The Direct Exchange geothermal heating system is specifically designed for areas with minimal space for looping. This heating system utilizes short pipe looping that is installed below the ground level. Through this pipe looping the refrigerant is circulated.
This is different from other geothermal systems where heat transfer fluid is used. The use of the refrigerant eliminates the need for additional piping as the heat is transferred between the ground and the refrigerant.
The geothermal heating system uses copper pipes that provide an efficient latent heat exchange method. This mode of heat exchange results in increased heat collection from the ground. The copper pipe, which is placed directly on the ground, circulates the refrigerant, thereby, eliminating the need for a water pump and a heat exchanger between the water loop and the refrigerant loop.
The use of small pipes in the Direct Exchange geothermal heating system facilitates easy installation as well as provides high efficiency. This geothermal heating system is suitable for all kinds of radiant heating applications. The Direct Exchange geothermal heating system can also be used for heating domestic water. Savant Solar also designs customized geothermal heating systems based on the energy requirements of the house.
