What You Should Know About a Pool Heat Pump

A pool heat pump is a great way to help you extend your swimming season while saving energy at the same time. However, there are some things you should know about this type of heater before purchasing one for your pool.

First, a heat pump doesn’t generate its own heat like gas heaters do. Instead, it draws in heat from the air around it, and amplifies it before transferring it to your pool water.

How They Work

Heat pumps for pools are a lot like air conditioning, dehumidifiers and water coolers–they use dependable technology to move heat from one place to another. The heat pump pool heaters work by drawing in the outside air that has been heated by the sun, amplifying it and transferring it to your pool’s water.

The fan in the heat pump pulls in the warm air and circulates it over an evaporator coil within the unit. The liquid refrigerant in the evaporator absorbs heat from the air and turns into a gas. This warm gas is then sent to a compressor where it gets compressed and becomes even hotter. The hot gas travels to a condenser coil in which it transfers that heat to the water.

From here, it travels back to the evaporator and the cycle repeats itself. This is the main part of the pool heater’s operation.

This process uses a high pressure and low temperature refrigerant called Freon to absorb heat from the outside air. After a short time, this gas starts to cool. It then gets recycled back into the evaporator where it can absorb more heat from the air.

In the end, all of this hot refrigerant gets pumped back into the evaporator where it begins the process over again. This cycle happens over and over until all of the refrigerant is absorbed, and it’s time to send that warm liquid back into your pool.

What’s more, the pool heat pump doesn’t require any fuel tanks or energy lines to operate. This means that it’s easy to install and maintain, saving you a ton of money in the long run.

There are many different types of heat pumps, but they all work in the same basic way. These heat pumps are the most energy efficient heating options available, which is why they’re so popular with pool owners.

The most important thing to remember when considering a pool heat pump is to make sure it can handle the weather conditions where you live. If it’s too cold to operate, then you’ll need to turn it off until the weather improves.

Energy Efficiency

When it comes to pool heaters, a heat pump is one of the most energy-efficient options on the market. They can heat a pool at less than one-third the cost of gas, and they work in almost any weather.

They are particularly suited pool heat pump for warmer climates because they rely on the temperature of air instead of gas fuel to heat water. They are also more efficient over time, so they tend to last longer than traditional heaters.

In order to use the heat from the air, a pool heat pump draws in warm air via a fan and directs it over a set of evaporator coils. The coils contain a special liquid coolant that absorbs the air’s heat, which is then passed through a compressor and then through the condenser. The warm gas is then returned to the evaporator coil, where it’s again absorbed and heated.

The process continues until the freon reaches a temperature of about 200 degrees Fahrenheit, or 93 degrees Celsius. This heat is then transferred into the pool, which stays at a comfortable temperature.

A heat pump’s COP, or Coefficient of Performance, is a measurement that compares how efficiently a unit heats up water to the amount of energy it takes to operate it. Typical COPs range from 3.0 to 7.0, with higher numbers indicating better efficiency and lower energy costs.

However, a heat pump’s efficiency can be measured differently. Regulators have introduced a new measurement called integrated thermal efficiency (TEi). This number is based on a heat pump’s annual use and consumption of energy.

TEi is calculated using a formula that accounts for the heat pump’s average energy consumption during operation and standby. The TEi is a more accurate measure of heat-pump efficiency than a COP, which can be misleading in the long term.

In addition, heat-pump efficiency can be impacted by the location of the pool. Ideally, the pool should be in an area that receives plenty of sunlight. This will help increase solar gain and reduce energy costs in the long run. Choosing a location that is shielded from wind can also help the pool retain its temperature.


If you’re looking to add a heat pump to your pool, it is important to plan the installation in advance. This ensures the unit is installed correctly and complies with local codes and warranty terms.

First, find the right location for your heat pump. This is a critical factor in ensuring it operates properly and efficiently. You should choose an area that’s open to the outside, away from fences and other structures, foliage, and shade. This will provide sufficient airflow for the heater’s operation and prevent it from overheating.

Then, it’s time to plan the plumbing connections. This can be a fairly simple task, but you should make sure to follow the instructions carefully and to use rigid PVC piping instead of flexible tubing to ensure that water can flow to and from the heater. If you are unsure about these details, hire a plumber to do it for you.

Once you have the pool heat pump plumbing set up, it’s time to attach the heat pump to your existing filtration system. This will require the use of rigid PVC piping, and you may need to hire a plumber to complete the work.

As with most other plumbing jobs, you’ll need to consider the layout of your pipes and the type of equipment that you have. This will help you select the right size piping for the job. You should also ensure the heat pump is located in the last section of your filtration system to avoid concentrated chlorine from flowing back into the water and affecting the heater.

You should also install a bypass valve so that the heat pump can be used without relying on your pool’s water pump to circulate the water. This is especially helpful in summer when you don’t want to heat the water, or if you are dealing with heavy chemical treatments.

Once you’ve completed the installation of your pool heat pump, you should be able to enjoy comfortable pool temperatures all year round without a significant amount of extra cost. Just remember to follow the installation guidelines, and to check your unit’s manual before turning it on.


If you drove a car off the lot and never threw it in the garage for a tune-up, you’d be pretty surprised at how clunky it would be after a while. That’s why it’s important to keep your pool heat pump in tip-top shape and avoid the need for costly repairs.

Your pool heat pump is just like your car – it has many moving parts that need to be cleaned and maintained in order to keep functioning properly. That’s why it’s important for you to schedule maintenance on your unit regularly to ensure that it’s working as it should be and doesn’t break down in the middle of a swim season.

In fact, it’s best to get your heat pump serviced at least twice a year, so you can be sure that everything is in top working condition when the swimming season starts. Fortunately, spring and fall are the most ideal times to schedule this type of maintenance because they’re less busy for HVAC technicians.

One of the most effective ways to maintain your pool heat pump is by cleaning its air coils. When the coils are dirty, they can slow down the flow of air through them, reducing the unit’s efficiency in transferring heat to the pool water. This can also cause the unit to work harder than it should, which will shorten its lifespan.

Another way to prevent a broken heat pump is by keeping your pool free of leaves, pine needles, and other debris. These particles can easily enter the unit, leading to damage to the motor and other internal components.

Using a pool cover is also a good idea to help protect your heater and make it more energy efficient. By preventing the sun’s rays from entering your unit and heating the pool, you can reduce the overall energy use of the system and save on your monthly power bills.
