Geothermal Pool Heater

However, geothermal heat pumps are 80-90% more efficient than gas heaters, which means they can save hundreds of dollars in energy costs each year. Additionally, they reduce dependence on fossil fuels and cut carbon emissions.

While geothermal heat pumps can save money over time due to energy savings, they do require a high initial investment. Also, it is more cost-effective in the southern U.S. rather than the northern U.S. because of climate conditions.

How Does It Work?

The geothermal pool heat pumps works by collecting heat from the stable ground. Although the air temperature in the winter is very volatile, the upper 10 feet of Earth's surface maintains a nearly constant temperature between 50-60°F, depending on latitude.

Geothermal heat pumps utilize that warm temperature through a series of underground loops that collect the heat. Then, a heat pump concentrates that heat and applies it where needed.
Geothermal heat pump systems for swimming pool heating have 3 main components:

• Ground side to get heat out or into the ground

• Heat pump (allows the transfer of heat from lower temperature level to a higher one)

• Swimming pool equipment for transferring the heat into the pool

Most of this equipment is underground, which is another advantage over conventional pool heaters.
