Why Geothermal Lake Systems Ideal For Pool Heating
A geothermal lake system is an ideal source for heating your swimming pool. Florida residents are blessed with many lakes that are a dependable source of latent heat to be utilized by a water-source heat pump to heat the water in your spa or swimming pool.
Unlike a gas-fired heater, the geothermal heating process takes place without combustion or any of its environmentally-unfriendly byproducts. A geothermal lake system is also a more energy-efficient method of heating a spa or pool. The system requires only electricity to operate the circulation pump and compressor. Depending on the water volume in the pool, heating costs can be reduced over 70 percent compared to gas heating.
Here’s an overview of a typical geothermal lake system:
- Water is drawn from the lake and pumped to a coil containing refrigerant that extracts latent heat from the water. The refrigerant then passes through a compression process that concentrates the heat load of the refrigerant substantially. The lake water is returned to the lake through a separate line.
- Hot refrigerant is conveyed into a condenser heat exchanger incorporated in the heater. Pool water circulating through the heat exchanger is heated without any contact or mixing with lake water. This transfer of heat energy directly into the water is highly efficient, with much less heat loss than an air-source heat pump or a gas-fired heater.
- When the temperature in the pool registers below the thermostat setting, the system cycles on to deliver heated water into the pool and raise the temperature to the set point.
