The Geothermal Pool Heat Pump: How It Works
Need a pool heat pump? Consider going geothermal. Geothermal heat pump systems, which have been in use since the 1940s, use 25 to 50 percent less electricity than standard systems. Air-source heaters, the most common type used to heat pools, require up to 44 percent more energy to do the same job than a geothermal heat pump. Because geothermal heat pumps have fewer moving parts and the pumps are housed indoors, they are very durable and can last longer than air-source heat pumps.
