The comfort of a heated swimming pool can extend the swimming season and enhance your quality of life. Nevertheless, a heated pool requires careful consideration of various factors, such as system choice, energy efficiency, and budget considerations.

It is the purpose of this article to guide you through these critical considerations.

Different types of pool heaters

When it comes to pool heaters, there are three main types to consider: gas heaters, electric heaters, and heat pumps. Each type has its set of advantages and considerations.

Heat pump

Heat pumps for pools are known for their longevity and energy efficiency, utilizing ambient air to heat the pool water. Despite the high initial investment, the operating expenses are generally lower, making it a profitable option in the long run. 

Solar heating

Solar panels harness the power of the sun to heat the pool water, eliminating the need for traditional energy sources. Furthermore, solar heating systems are environmentally friendly, as they emit no greenhouse gases.

Gaz heater

Gas heaters provide fast heating, but may require a propane or natural gas supply. For countries with cold climates, they are an excellent option.

Note: Gas heaters are no longer allowed to be installed in new buildings in France since 2022.

Electric heater

Despite being cheaper to install, these heaters are more expensive to operate. They are generally less efficient and are more suitable for smaller pools or occasional use.

Find out what you need

It’s important to identify your needs before buying a pool heater. You may be fine with a simpler system if you don’t use your pool much. You’ll need a more powerful system if you plan to use your pool regularly. It’s also important to make sure your filtration system works with the heater.

Take a look at energy efficiency

Minimize your costs and environmental impact by opting for energy-efficient systems.

Design your heated pool now!


The key to energy efficiency is not simply choosing the right type of heating. This applies to the entire design of your pool as well. In the long run, these factors can have a significant impact on your energy bill.

Thermal insulation

The heating requirements of a well-insulated swimming pool will be significantly reduced. It is possible to use insulating materials such as polystyrene for this purpose.

Filtration pump

A high-efficiency filtration pump will ensure that heated water is circulated more efficiently, resulting in increased energy efficiency. To achieve the best results, choose a pump with variable speed.

Protect your pool with a cover

The use of thermal covers or bubble covers in swimming pools can greatly reduce evaporation. Evaporation is the primary cause of heat loss in swimming pools.

The cost of installing and running a heated pool

There are several factors that can affect the cost of installing and operating a heated pool. These factors include the size of the pool, the type of heating system used, the energy efficiency of the system, the climate of the area, and the duration of swimming throughout the year.

There is a wide range of costs associated with different heating systems. In terms of cost, an electric heater is the cheapest option, while a solar heating system or a heat pump is the most expensive.

Installation can also be costly, depending on the complexity of the system. For this type of work, professionals should be consulted.

There is a relatively low cost associated with maintaining pool heaters. However, a gas heater may require annual technical inspections, which can increase costs.

If you choose an inefficient system, such as electric heating, your energy costs can add up quickly. Solar heating is clearly the most economical option.

You should design your heated pool based on the climate in your area

Climate can have a significant impact on pool heating efficiency. Several factors can have an impact on your choice and needs, such as sun exposure, outside temperatures, and even altitude.

Sun exposure

Solar heating is particularly effective in sunny climates.


It is important to understand that high rates of precipitation can result in a faster loss of heat, requiring a more powerful heating system.

Average temperature

If you live in a cold climate, a heat pump or gas heating may be more suitable as a heating option.


When it comes to installing a heating system for your swimming pool, you should take this decision seriously. There are many factors to consider, including the type of heating, energy efficiency, cost, and climatic conditions.

By planning and researching carefully, you will be able to make the most of your heated pool while minimizing your costs and environmental impact.
