How Does a Heat Pump Work?

Heat pumps work by transferring energy from one source to another. The most commonly used heat pump in swimming pool applications is an air to air heat pump. This type of heat pump works by collecting the warmth in the ambient air and moving it across an evaporator coil which turns a liquid refrigerant, such as R-410A, into a gas. This hot gas is then compressed in the compressor which increases the gas temperature while continuing on its journey towards a condenser. As the the super heated gas passes through the condenser heat from the gas is transferred into the water that is circulating through the heat pump. The hot gas will then be cooled using a thermostatic expansion valve and returned to its liquid form where the entire cycle will repeat itself. During this process the heat is transferred rather than created. This process is more efficient vs other heating methods.

Todays heat pumps can be six times more efficient vs gas heaters. Heat pump manufacturers measure the efficiency of heat pumps by assigning them a C.O.P rating. What C.O.P stands for is coefficient of performance and it is a measure of how much heat can be generated vs the amount of electrical input required. Think of it this way... if you spend one dollar in electric heating your swimming pool using a heat pump you get $5.00 dollars worth of heat with a heat pump that has a C.O.P rating of 5. If this were a gas heater and you spent $1.00 in you would only receive about 80 cents worth of heat.

Simply put... modern swimming pool heat pumps are green, clean, an and eco-friendly way to heat your pool.
