Pool heating

Pool heating

It is wonderful to have a swimming pool in the garden, but unfortunately the Belgian weather can be disappointing. Efficient pool heating can easily extend your swimming season. After all, you want to swim in water with a pleasant temperature. But which pool heater should you choose? Below, we will discuss the various possible pool heating systems.

A heat pump to heat your pool

A heat pump is the best and most economical way to heat a swimming pool. No wonder it is the most popular pool heater in Belgium. A heat pump extracts heat from the environment and then adds it to the pool water. Although it is a bit more expensive, you will soon recover the purchase cost because a heat pump consumes very little electricity. The payback period is therefore also much shorter compared to other heat sources. A heat pump is the most convenient way to heat the pool water.

Benefits

  • Efficient
  • High yield
  • Energy-saving
  • Simple to use
  • Durable
  • Environment-friendly

Disadvantages

  • Higher purchase price
  • Depends on the outside temperature. Temperature must be higher than 10 degrees.
  • Takes longer to heat your pool water (2°C per day).

With a high-quality heat pump combined with a good pool cover, you spend about 650 euros per year on heating costs for your pool, on the condition that you only use the pool when the outdoor temperature is above 10°C. If you want to use the pool all year round, you should use a heat exchanger during the winter months.

Heat exchanger

A heat exchanger transfers heat from an external heat source, such as a central-heating boiler, a solar water heater or even a heat pump, to the swimming pool water. A heat exchange takes place when the hot and cold water flow in opposite directions in the heat exchanger. In this way, the warm water from the central-heating boiler, for example, transfers heat to the cold pool water without coming into contact with each other. This technique is ideal for people who want to heat their pool quickly. The entire pool is heated in just one day and will be ready for you to enjoy.

Benefits

  • Cheaper purchase price
  • Heats the pool water quickly.

Disadvantages

  • Consumption costs are expensive.
  • Less ecological
  • Always in combination with another heating system

Because the heat exchanger is connected to the existing heating system, it is cheap to install. However, the consumption costs for a heat exchanger are very high. If this is the only way you heat the pool, you are guaranteed to get an extremely high energy bill afterwards. Moreover, this type of pool heating is less ecological, which is something that has become very important nowadays.

Solar pool heating

Another option for heating your pool is to use solar pool heating. You can choose between heating with a solar boiler or with solar panels. These systems are sustainable, energy-efficient and good for the environment. However, they are relatively expensive to buy and are dependent on the sun. On cloudy days, you get less energy and it is precisely then that the pool needs extra heating.

Benefits

  • Environment-friendly
  • Low consumption costs

Disadvantages

  • Higher purchase price
  • Depends on the sun.

Wood-burning pool heater

The final option is to heat the pool with wood. The pool water passes along the wood-burning stove and receives the heat from the fire. However, operating a wood-burning stove is rather labour intensive, as wood has to be added constantly. Moreover, wood is not cheap. This type of pool heating can be used for smaller pools that are used occasionally.

Benefits

  • Good for occasionally used small pools.

Disadvantages

  • Expensive wood purchase price
  • Very labour intensive

Do not forget your pool cover

Once the pool water has been heated, it is important to keep it warm for as long as possible and ensure that the heat does not escape. Therefore, we always recommend to cover the pool with an automatic roller shutter. This ensures that the pool water does not cool down so quickly, thus saving energy. If you choose solar slats, the water temperature will even rise when the pool is not being used on sunny days. In short: nothing but advantages!
