Choosing the Best Pool Heat Pump – Buying Guide
Besides the basic specifications listed above, there are other important factors related to pool heat pumps. The first step to deciding on which type of heater fits your pool best, you need is to take into consideration these following things.
The Pool’s Size
It is crucial to determine your pool size to match it with the correct BTU output. If you aren’t sure how many gallons you have, measure your pool, and use this pool volume equation. Use the following equation to get an approximate heat pump BTU requirement:
(Surface Area) x (Temperature Increase) x 12 = (Minimum BTU Needed)
After determining the volume of your pool in gallons, follow this general guideline for heat pump BTUs:
|Pool Volume (Gal.)||Heat Output (BTU)|
The COP of a heat pump generally measures between 3.0 and 7.0, which translates to an efficiency rate between 500% and 600%. Therefore, the higher the COP number for the pool heater, the more energy-efficient it is.
So speaking of COP, choose a high efficiency. Since no one wants to waste unnecessary electricity, this is why fitting the right side of the heat pump for your pool is of primary importance for optimum efficiency and minimizing energy costs.
Noise from a swimming pool pump on a residential premise that can be heard must cease during certain times: before 8 am or after 8 pm on any Sunday or public holiday, or before 7 am or after 8 pm on any other day.
So this is a valid consideration when it comes to your peaceful and quiet environment, or sometimes due to its close locations to your neighbors. You should look into the factors that affect the noise level: the fan blades’ pitch, the fan motor, and the compressor.
Not all heat pumps were designed to heat pool water at lower temperatures. Most heat pumps shut down when the outside temperatures go down below 55° degrees, while some can continue to operate down to the mid to low 40s.
The colder the air, the less heat your heat pump will be able to produce. So it’s crucial to buy a pool heat pump based on your local weather condition to determine the most suitable heating power for the most efficient result without it being damaged.
How Does a Heat Pump Work for a Pool?
Pool heat pumps are extraordinarily efficient because they use electricity and do not generate heat to warm pools or spa water. Instead, heat pumps have a fan which transfers heat from the outside ambient air that has been warmed by the sun into the water.
Pool pumps use electricity to draw “free” heat in from the air and then transfer the heat to your pool water. Humidity plays a big role in how well the heat pump will work. The more humidity or moisture in the air, the more heat a heat pump can extract.
The pool pump circulates the swimming pool water drawn from the pool. It then passes through a filter and the heat pump water heater. The heating process begins when the Liquid refrigerant gas and water from the pool is pumped through the heat exchanger.
The water is warmed up 3-5 degrees as it passes through, and then the warmer water flows back into the pool. The hot gas, as it flows through the condenser coil, cools down into a liquid form and back to the evaporator, where the whole process begins again.
Now, the cooled liquid refrigerant passes through an expansion valve, which controls the flow of the refrigerant from the high-pressure side into the unit’s low-pressure zone. As pressure is released, the refrigerant becomes a hot, high-pressure gas.
Then incoming air interacts with the cooling liquid (refrigerant) inside of the evaporator coil. As the refrigerant expands into a gas, it cools rapidly. It circulates through the evaporator coils, which results in the cooling liquid becoming warmer and warmer.
The heater needs to be installed between the pool filter and the chlorine generator. Since you need to make sure that the water is entirely free of particulates or dirt when it enters the heater, and contact with corrosive chemicals should be kept to a minimum.

The Difference Between a Pool Heater and Heat Pump
Electric pool heaters and pool heat pumps both run with electricity. The difference is that pool heat pumps are more electricity cost-efficient as it transfers the warmth of the air into the water.
Although long-term run costs are low, heat pumps do have a slight disadvantage. Since heat pumps use the surrounding air around the unit to heat the water, heat pumps lose their heating efficiency when temperatures drop below 50 degrees.
Unlike heat pumps, pool heaters can heat water temperatures quickly at any temperature. They also have a lower upfront cost. But they require higher utility and run costs in the long-run, which eventually costs even more than the original price.
