The water in your pool may get freezing in winter, and for that reason, you may not have fun with friends or exercise there. However, you can enjoy your pool throughout the year when you install an efficient water heating system.

The pool water is usually at 22°C on an ordinary day or 25°C when it’s scorching. However, sport swimmers compete when the water is at 26°C. That means that the water has to be heated and, in some situations up to 29°C-30°C.

Further, heating stretches the swimming season by four months; thus, it can last from April to the end of October, while in average temperatures, it ends in August. You can enjoy swimming the entire year if you install specific systems with the capacity to heat the pool adequately.

Water Solar Heating Method

Heating the pool with energy from the sun is one of the most attractive and simple ideas. It’s an environmental-friendly and energy-efficient method. There are several water-heating options available in the market. They include.

Solar Water Heater

The option is mainly used in sanitary facilities or residential properties and is pegged on the number of panels that are installed on the roof. Thus, with such an installation, you can heat your home and your pool.

The method is eco-friendly when compared to fuel and gas heating; however, you need the sun to support the solar water heater.

Thus, this form of water heater is not the best due to reduced efficiency on dull days, yet these are the days when you need to heat the pool to make it useable. Therefore, the solar water heater is only efficient on sunny days.

Solar Panel

The method emits energy rather than heat. The energy is environment-friendly; for it uses an electric heating system to heat the pool and home. You can also improve its efficiency by combining solar panels and heat exchangers.

There are different types of solar panels based on the purchase price, quality, capacity, and model of the solar panels, as well as the size of your family.

On the other hand, you need a large surface area for solar panels installation. The available area should also be facing southwards.

Still, the cost of installing solar panels is higher, can only be used in summer, and you need solar collectors, thus a larger space for their installation.

EDPM or Solar Mats

Unlike other solar heating methods, solar mats are used to heat pools in winter. Therefore, water is passed through solar or EDPM mats, which are heated by the sun then the pool water.

The solar mats are mainly used in smaller pools because they have a lesser volume of water as compared to bigger pools. These pools require less time to pump the entire water through solar mats.

On the other hand, solar mats require a large area for installation. It’s recommended that space should be equivalent to the size of the swimming pool. They should be installed on a rooftop, and the pump should be strong enough to pump the entire water to the top. Otherwise, the pool water will not get heated or will do so slowly.

Dome-Shaped Solar Collectors

Solar collectors operate the same way as solar mats. The only difference is that they take less space because pipes are rolled around on the dome. Therefore, a single solar collector can heat up to 5,000 litres of water. However, the method is still applicable in small pools, depends on sunlight, and requires a lot of energy to pump water in all the domes.

Titanium Heat Exchanger

This type of heater is suitable for people who don’t use the pool regularly because it heats the pool water only for one day. The heat exchanger has a heating element that is made from titanium, thus corrosion resistant.

It uses electricity to heat water; thus, it’s connected to the heating system at home. Although it’s inexpensive to install, it has a high energy consumption; therefore, your bill will rise if you use it to heat the pool water.

The main benefit of this water heating system is that you can use the pool at any time of the year. On the other hand, it’s not environment-friendly, but you can combine it with either a solar boiler or a heat pump.

Heat Pump

The heat pump is the most popular water heater over the years since it doesn’t rely on the sunlight. The method is economical, highly efficient, durable, and easy to use. It’s environmental-friendly than a fuel or gas heating system. Further, you can use it throughout the year and for a more extended period; therefore, you should choose a superior quality heat pump.

A heat pump extracts heat from external air and uses it to warm the pool water. The entire process is supported by electricity since the pumps don’t generate their heat. They depend on the external temperature, and therefore, they are only efficient when air is 10°C and above. For instance, the pump requires a 1kW of energy to generate 5kW.

Just like solar-powered heaters, the heat pump only operates when the temperatures are favourable. Therefore, you can only use your pool from April to the end of October and not throughout the year.

However, you can enjoy the water if you invest in specific heat pumps that function well even when the temperatures are lower. They should also be installed outdoor to help them blow out cold air, thus improving their efficiency.

It’s important to note that the heat pump doesn’t need direct sunlight like the solar heaters; what they need is ambient temperature. That means that the area around the pump should be free from any obstruction to allow the fan to release cold air. Therefore, no item should be placed 3-5 m near this fan.

Additionally, you can install the pump behind the pool house or around a corner because of the noise. The market is yet to produce low-noise heat pumps.


You can use a wood stove to heat the pool water by running it along with the stove. It is used occasionally in smaller pools because the method is expensive and labour-intensive.


There are different methods of heating your pool water. Some of them are eco-friendly, while others are not. The powdered solar method is less expensive, while the electric ones will increase the energy bill.

Your primary focus should be to select a method that will keep your water warm for an extended period and at a lower cost so that you can enjoy swimming for many months.
