A geothermal heat pump uses electricity to power the compressor, fan and circulation pumps. These important components help the heat pump move heat from the floor and into the home through the steam compression and cooling cycle. In conclusion, a SEER 30 6-ton geothermal heat pump consumes 4.6 kWh of energy. An air conditioning unit of the same size would consume approximately 7 kWh.
Factors that help reduce costs include economies of scale for large community, commercial or even residential applications and increased competition for geothermal equipment (especially from major brands such as Bosch, Carrier and Trane). Open loops, which use a pump and a reinjection well, are cheaper to install than closed loops. Geothermal heat pumps are more efficient and consume less electricity for cooling than even hyperefficient central air conditioning systems. Matt Davis is the co-founder of Ground Energy Support, which provides real-time monitoring of geothermal heat pump systems to homeowners who want to ensure that their systems are operating efficiently.
Just as a perspective, all modern central heating and air conditioning systems rely on electricity to function; just like a geothermal system. While this gives us an idea of how well geothermal heat pumps work, it doesn't give us a horsepower. That's because standard air conditioning units remove hot air from your home and release it to outdoor heat, while geothermal heat pumps move warm air to the floor by 50 degrees, where it's easier to accept. Geothermal heating and cooling systems are the most efficient and environmentally friendly systems on the market today.
Geothermal heat pumps only preheat sanitary hot water, so the cost savings aren't that great because you still need to use your hot water heater to recharge it. A typical central air conditioner has a SEER rating of 14 to 16, while a geothermal heat pump system has an average EER rating of 20 to 30. To recover from a difficult period, the tense geothermal system will likely need the help of an additional heat source, such as an electric resistance heater. The advantage of a geothermal heat pump is that prices don't fluctuate quickly, stability has a value.
For every 1 unit of energy used to power your geothermal system, an average of 4 units of thermal energy are supplied. Geothermal heat pumps are sold to customers as a way to save on utility bills, but that is not what happened in this case. This process makes heat pumps much more efficient than conventional sources, and that is why they are known as the most efficient source of heating and cooling available today. Geothermal air conditioning (heating, ventilation and air conditioning) brings a building in harmony with the land below, taking advantage of underground temperatures to provide heating in winter and cooling in summer.
When propane is very cheap and electricity is relatively cheap, geothermal heat pumps only save a small amount compared to propane.
