Air Source Heat Pump For Swimming Pools

Air Source Heat Pump For Swimming Pools

If you’re looking for an efficient way to heat your pool, an air source heat pump could be the answer. Find out how these systems work and how they compare to other heating options like gas heaters.

They use electricity to power a fan that pulls the ambient air over an evaporator coil, heating the refrigerant inside. This is then passed around the pool, keeping it warm all year round.


Using the latent heat in the air, this type of pool heater is becoming increasingly popular. It does not use any gas or propane resources, which is a plus for those who wish to lower their utility costs. Moreover, it uses about 80 % fewer fossil fuels to generate the same amount of heating output as a traditional pool heater that runs on natural gas.

It draws the air from the environment and passes it over an evaporator coil that is super heated with a liquid coolant. This coolant absorbs the heat from the air, which is transferred to the pool water before it returns back to the evaporator coil. The cycle is repeated over and over. The evaporator coil is made of titanium, which makes it resistant to corrosion and safe for pool chemicals.

In the long run, this system will save you money as compared to other types of heating systems that use gasoline or propane. This is because it does not have a combustion process, so it eliminates the need for supplementary fuel and maintenance. It is also quieter and requires less maintenance.

However, this system has its own drawbacks when it comes to costs. Its reliance on the air temperature will make it less effective in cold climates and will require longer cycles to raise the temperature of the pool water.

Energy Efficiency

An air source heat pump harvests energy from the air air source heat pump for swimming pool to warm your pool and does so without burning any fossil fuels. This is what makes it a cleaner and more sustainable option for heating your swimming pool than using gas or propane heaters. This also reduces your overall energy consumption.

The heat pump’s outer evaporator air coil acts as a heat collector. Liquid refrigerant gas absorbs the available heat energy from the air converting it to high-pressure liquid that is then pumped by the compressor. This hot liquid is then pushed through the heat exchanger where it transfers its energy to the pool water. The warmed water then leaves the heat exchanger and returns to your pool filtration system or, in some cases, to your spa.

When deciding what size pump you need, it is important to know how many hours you want the pool heated each day. A good guide is to choose a unit that is rated at about 8 kilowatts. This will provide adequate heat output for most pools. However, it is also important to consider the pool’s filtration system flow rate and the amount of time that it will be recirculating.

It is also a good idea to install a water air source heat pump for swimming pool flow meter in the piping that runs to and from the heat pump. This will help you keep track of the pump’s performance and to ensure that it is not working too hard or inefficiently.


Unlike traditional gas or propane heaters that require large fuel tanks and costly energy lines, pool heat pumps use the latent heat of the air and the power of electricity to heat your pool. This makes them a great choice for people who want to reduce their carbon footprint and energy bills.

During operation, the pump draws the ambient air into the system through the outer evaporator coil, where liquid refrigerant absorbs the heat of the surrounding air and transforms it to heated water. This hot water is then pumped into the heat exchanger, which is where the actual heating takes place. The warm water is then pushed back into the pool, leaving your pool with a comfortable temperature for swimming.

For each unit of electric energy that the heat pump consumes, it moves two or three units of heat from the air into your pool, making it very efficient in terms of energy use. This means you can enjoy your pool year round without spending a fortune on high utility bills.

When choosing an air source heat pump for your pool, you need to consider the dimensions of your swimming area and your desired operating temperature. For example, if you have an outdoor pool and a desired temperature of 28 degrees Celsius, it is recommended that you opt for a model with a titanium heat exchanger, as this will be more resilient to rust and other environmental factors.


Unlike gas pool heaters, which require large fuel tanks and energy lines to operate, heat pumps use electricity to absorb heat from the air. This method is a lot cheaper and has less impact on the environment. It is also a great option for swimming pools in colder climates.

Installation: When a pool heat pump is properly installed, it can provide years of reliable service. A qualified professional should perform all installation steps according to the manufacturer’s guidelines. It is important to choose a location that will minimize piping and electrical wiring lengths, as well as have adequate space for maintenance access. The location should be close to the pool equipment pad or the pool itself, and it should be free of obstructions that could interfere with operation.

Test and Start-Up: After installation, the heat pump should be tested to make sure it is operating correctly. During the testing process, it is a good idea to monitor the system for any leaks or problems. Once the unit is ready to be started, it should be filled with water and run according to the manufacturer’s instructions.

Regular maintenance of a pool heat pump is essential to ensure optimal performance and longevity. It is recommended to clean or replace the air filters, inspect and clean the evaporator and condenser coils, and check refrigerant levels regularly. In addition, it is a good idea to follow the manufacturer’s shutdown procedures during non-use periods.
