Heat Pump COP
Air-source pool heat pumps heat your pool using a minimal amount of energy (up to 8 times less than gas heaters). In pool heating, this is referred to as a
COP or Coefficient of Performance.
The average pool heat pump COP sits at about 6.0, producing 6 units of energy for every dollar spent, which is good.

What is a pool heat pump?
A heat pump pool heater is a machine that uses a reversible high-pressure refrigerant system to heat or cool water. The refrigerant combines with warm air drawn in from the atmosphere to produce heat.
How do air-source pool heat pumps work?
“Air-source” implies that a heater sources its heat from the air in the environment. The heat transfer process takes advantage of heat’s natural ability to move from a high-temperature area to a lower one. Using a small amount of energy, air source pool heat pumps use a fan to harvest heat, and later distribute that heat into your pool water. The main components involved in the heat transfer process are the fan, evaporator coil, compressor and heat exchanger. Here’s a detailed explanation to give you a better idea:.
The process starts when the fan draws in warm air from the environment and passes it through an evaporator coil. From there, the liquid refrigerant within the evaporator coil reacts with the air and forms a warm gas. The compressor then pressurizes the warm gas into a hot gas, and pumps it through a titanium tube located within the heat exchanger . This is actual heat transferring takes place.
At this point, the water from your pool flows through the heat exchanger and passes over the heated titanium tube. Two things happen during this exchange. The hot tube disperses its heat into the flowing water — at the same time, the water helps cool down the hot titanium tube, preventing it from overheating. Finally, the heated water is pumped back into the pool, and you enjoy the comfort of a refreshingly warm swim.
(On a side note: A reversing valve located near the compressor controls the direction of the refrigerant flow, which aids in both cooling and defrosting coils during colder temperatures.)

What is a Coefficient of Performance?
All pool heaters require a simple and easily identifiable way to gauge their performance in terms of energy use. This is where a coefficient of performance comes into play. A COP is a ratio that measures the amount of energy a heating/cooling appliance outputs to the amount it consumes. The formula for calculating a unit’s COP looks like this:.
