| The term geothermal means Earth / Ground | | | | This means that geothermal heat pumps are |
| Heat. How does geothermal heat pump work? | | | | sometimes not suitable for standard hot water |
| Geothermal, or ground source heat pumps, use | | | | baseboard applications, which are made for |
| the continual ground or groundwater | | | | heating water temperatures of 180 degF. Floor |
| temperatures. These heat pumps use geothermal | | | | heat and low-temperature radiators require water |
| energy to heat and / or chill your home. | | | | temperatures in the range of 95 to 140 degF. |
| A refrigerant loop with a compressor extracts | | | | Some newer heat pump models are now supplied |
| heat from one side ( the ground ) and pumps it | | | | with so-called desuperheaters that will transfer |
| to the heating loop in your house. It is pretty | | | | excess heat from the geothermal heat pump |
| much the same process that occurs in your chiller | | | | compressor to the domestic water heater. |
| : heat is extracted through a compressor and | | | | Water-To-Air Geothermal Heat Pumps |
| refrigerant loop from the inside of your chiller / | | | | The Water is the heat sink, where you reject the |
| freezer and defied into your home. | | | | heat from the house. |
| In the summer the geothermal heat pump | | | | Otherwise, these heat pumps function the same |
| reverses its cycle, if you've got an air-conditioning | | | | way as water-to-water heat pumps. And again, |
| system, and heat from the home is rejected into | | | | the potency of a geothermal heating and cooling |
| the ground or ground water. | | | | system is far better of a conventional system. |
| What makes geothermal heat pumps such a good | | | | Crucial to Knowstep 1 towards making a |
| choice for residential heating and cooling is that | | | | geothermal heat pump system be a reliable and |
