Active Heating and Air

Why Geothermal:

Geoexchange (geothermal) heating and cooling systems are the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available, according to the Environmental Protection Agency ^{1. EPA found that geoexchange systems can reduce energy consumption–and corresponding emissions–by over 40% compared to air source heat pumps and by over 70% compared to electric resistance heating with standard air-conditioning equipment. Combining geoexchange with other energy-efficiency measures (such as window or insulation upgrades) can increase these savings synergistically.} How Geoexchange works:

Heat exchanger designs include

Geoexchange systems use the Earth’s energy storage capability to heat and cool buildings, and to provide hot water. The earth is a huge energy storage device that absorbs 47% of the sun’s energy–more than 500 times more energy than mankind needs every year–in the form of clean, renewable energy. Geoexchange takes this heat during the heating season at an efficiency approaching or exceeding 400%, and returns it during the cooling season. Geoexchange heating and cooling systems use conventional vapor compression heat pumps to extract the low-grade solar energy from the earth. In summer, the process reverses and the earth becomes a heat sink. closed loop systems which use horizontal or vertical heat exchangers made of heat-fused high density polyethylene pipe. These systems usually circulate water with a biodegradable antifreeze added. Open loop systems generally draw ground water through the heat pump, and return it to the ground unaltered except for a all temperature change.

 Geoexchange is renewable: 

More efficient systems, better building envelopes, and art ventilation in commercial systems minimize the amount of geothermal heat exchanger required, giving geoexchange building designers strong incentives for more efficient building designs. In residential geoexchange applications, and improved shell efficiency also pay strong dividends in both first costs (by allowing equipment down-sizing), and operating costs, to a far greater extent than for conventional heating and cooling systems. Geoexchange domestic hot water, through “desuperheaters,” shipped with about 80% of all units today, and through “full condensing” hot water systems, can save consumers several hundred dollars per year.
