Heat Your Swimming Pool With an Air Source Heat Pump

If you’re looking to heat your swimming pool, an air source heat pump is the way to go. They’re more energy-efficient than gas heaters and are easy to maintain.

The best way to determine which type of heating system is right for you is to think about your lifestyle and how much you use the pool.

How it works

If you’re looking to heat your pool without burning fuel, an air source heat pump may be the right option for you. Instead of using a gas heater, which requires natural or propane to operate, an air source heat pump uses electricity to capture heat from the surrounding air and transfer it to your pool water.

Air temperature and humidity play a big role in how well an air source heat pump works. For example, warmer air has more moisture and therefore contains more heat than cooler air.

In the first step, a fan pulls in warm ambient air and circulates it over an evaporator coil. The liquid refrigerant inside absorbs the available heat from the air, turning it into a warm gas. The heat from this gas is then pumped by the compressor into a condenser.

The hot gas from the compressor is then cooled by the condenser, which transfers some of its heat to the cooler pool water that is circulating through the heat pump. As the refrigerant cools, it reverts back to a liquid form and enters the thermal expansion valve. The refrigerant is then allowed to expand to lower its temperature and pressure before it starts the process again.

Once the refrigerant has absorbed enough heat, it is sent to the heat exchanger. The heat exchanger consists of an inner titanium tube, where the heat is air source heat pump for swimming pool transferred to your pool. The outer titanium tube is where water flows past the heated heat.

This is a process that happens over and over again until your pool has reached the desired temperature. It takes some time, but the air source heat pump works quickly and effectively to heat your pool.

Because of the way it works, the air source heat pump is more energy-efficient than a gas heater. Moreover, it doesn’t require any natural or propane gas to run, making it a cost-effective choice for homeowners. Plus, it can be used to heat your pool year-round. If you’re considering purchasing an air source heat pump for your pool, be sure to look for a model that features a quiet, acoustic compressor cover and profiled fan blade.


An air source heat pump is a great alternative to gas or electric heating for your swimming pool. They are more efficient than both and cost less to run. They are also a more environmentally friendly option.

An air-source heat pump works in a similar way to a refrigerator, capturing heat from the surrounding environment and turning it into heating for your pool. The compressor uses a refrigerant to pressurise a vaporised gas, which then absorbs heat from the ambient air, which it then passes through the heat exchanger into your pool water. The cooled freon is then sent back into the compressor and re-pressurised, and so on until the desired temperature is reached.

When installing an air-source heat pump for your swimming pool, make sure that the unit is properly sized and positioned. For best performance, place it before any chlorinators or chemical pumps and after any filters or swimming pool pumps. You will also need to install a corrosion-resistant check valve between the outlet of your heat pump and your chemical feeder or chlorinator, as this will stop any concentrated chlorine from flowing back into your heater.

As with any other new system, plan your plumbing layout carefully, using as few fittings as possible. Ideally, you should only use PVC connections and elbow fittings matching the size of your existing piping.

Before installation, you should inspect your power supply to ensure that it is adequate to support the new heat pump. If it isn’t, you will need to add a dedicated line. A qualified electrician should be able to help you with this.

You should also install a thermostat to control your heat pump’s operation and ensure that it is always running at a temperature that suits your family and pool needs. This will also reduce the chance of a fire or explosion.

Once you have installed your new heat pump, follow the directions in your owner’s manual to turn it on. You can also get a flow meter to measure the water flow rate through your pipes, so that you can check that the system is working correctly.


A pool heat pump works by extracting heat from air outside your home and transferring it to the water in your pool. It does this by taking air through a device that looks like a car radiator and expanding and compressing a refrigerant gas.

A well-maintained heat pump can last for decades. This is because it doesn’t have components that need routine replacement, but you do need regular cleaning and an annual checkup by a professional to ensure everything is working correctly.

One of the most important maintenance tasks is to clean or replace the air filter on your pool heat pump. Dirty filters restrict airflow and cause the system to work harder, which stresses parts and shortens its lifespan.

Changing your filter is easy to do. Just follow the manufacturer’s instructions for this. Also, make sure the filter doesn’t have any debris in it, such as grass clippings or leaves. This will prevent your unit from overheating, which can damage parts.

Another crucial maintenance task is to check the condenser on your pool heat pump. It’s important to keep it clear of any dirt, debris or rust, as these can clog the tubes and reduce its performance.

You can do this by regularly brushing the exterior of your heat pump. You can do this yourself, or have a technician do it for you during your next service appointment.

Your technician will check the refrigerant levels in your unit and top up or replace them if necessary. This is especially important if you live in a cold climate and will help your unit operate more efficiently.

A properly maintained pool heat pump can also avoid the freezing up of your pool during the winter. A good pool heat pump will have a gas re-circulation system that passes the hot refrigerant back around the system to avoid frost formation.

Having an air source heat pump in your swimming pool can save you money on energy costs, and it’s also easier to keep your pool water at the desired temperature when compared to other heating options. However, like all household appliances, a pool heat pump can malfunction from time to time. These problems should be addressed promptly to prevent further issues from occurring, so call your local HVAC pro if you have any questions about your unit’s maintenance.


Heat pumps are a great way to keep your pool water at the proper temperature for comfortable swimming. They also reduce the amount of electricity needed to heat your pool, resulting in lower energy bills.

An air source heat pump works by capturing the warmth in the air around it and then moving it to your pool water. It does this by using a refrigerant (usually Freon) that can absorb and release heat. A compressor will then draw the refrigerant through a pipe to the evaporator, where a large coil and fan will vaporize the freon. The vaporized freon is then transferred to the condenser, where it can be used to reheat your pool water until it achieves the desired temperature.

This type of pool heating system is very efficient, and they have a long service life. They are also relatively easy to install, making them a great option for homeowners who prefer to do their own maintenance and repairs.

If you decide to go with air source heat pump for swimming pool an air source pool heater, it’s important to choose one that is sized correctly for your specific needs. It can be difficult to get the correct size if you’re not familiar with what your pool will hold, so it’s best to have a professional evaluate the space before you purchase a unit.

Most heat pumps are covered by a home warranty, but it’s important to read the terms of coverage carefully. Even the best home warranties will have a list of exclusions, which means that they may not cover certain appliances or systems.

A heat pump can be a very expensive appliance, so it’s essential to find a home warranty that is large enough to cover the cost of any repairs you might need. A few good options are American Home Shield and Choice Home Warranty, both of which offer a policy limit of $2000 for a heat pump, which should be more than enough to pay for any necessary repairs.

Air source heat pumps are a great choice for most homes because they are more affordable than other types of pool heating systems. They work well in Florida’s mild climate, and they can be used to both warm and cool your pool. However, they may struggle to maintain their intended temperature during the coldest part of the year.
