I’m considering a swimming pool heater pump, but I’m not sure how it works.

If you want an energy-efficient way to heat your swimming pool, consider using a heat pump pool heater. Heat pumps use electricity but do not generate heat on their own. There are two basic types of pool heat pumps. The most common is an "Air-Source", the other being "Water-Source". Air Source Heat Pumps use air as a heat source. The heat is collected and captured from the air and pumped into the heater unit’s compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating through the heater. The heated water then returns to the pool. Heat pump pool heaters work efficiently as long as the outside temperature remains above the 45ºF–50ºF range.

Selecting a Heat Pump Pool Heater While a heat pump pool heater costs more than a gas pool heater, it typically is more efficient and has a lower operational cost. In addition, heat pump pool heaters last longer than gas pool heaters. Heaters come in a variety of sizes, so it’s best to have a pool professional help you select and install your heater to help you optimize your value.
