Are all geothermal heat pumps alike?
No. There are different kinds
of geothermal heat pumps designed for specific applications. Many geothermal
heat pumps, for example, are intended for use only with higher temperature
ground water encountered in open-loop systems. Others will operate at entering
water temperatures as low as 25°F, which are possible in
closed-loop systems. Most geothermal heat pumps provide summer air
conditioning, but a few brands are designed only for winter heating. Geothermal
heat pumps also can differ in the way they are designed. Self-contained units
combine the blower, compressor, heat exchanger and coil in a single cabinet.
Split systems (such as the WaterFurnace Envision Series Split) allow the coil
to be added to a forced-air furnace and utilize the existing blower.back to listing
