Below is a radiant project that we completed. To the bottom left is a heat exchanger. Water is brought into the house from a well and provides cooling for the Geothermal Radiant Cooling System. This system is a supplement to the existing air conditioning for the house. The radiant cooled floors feel comfortable in the summer time and reduce the load of the air conditioning. All of this is done without a heat pump! The electrical consumption is lower then a compressor. Without the heat pump, installation costs were lower too. This is a nice alternative to some of the more expensive Geothermal systems.
