Solar pool heating system (solar collectors)

How it works

It’s the same principle as when a garden hose is left out in the sun on a hot summer day. The sun heats up the water in the hose.

The sun heats the collector, which in turn heats the water inside. The heated water then circulates through the pipes toward the pool.

Stages of the operating cycle of a solar thermal collector for the swimming pool

1. The pump draws the pool water from the swimming pool’s skimmer and drain.
2. The pump sends the water to the filter, which retains the fine particles that passed through the skimmer and drain.
3. The filtered water flows through the solar thermal panel where it absorbs the heat form the sun.
4. The heated water goes back to the pool.
5. Optionally, the water can be sent to a heat pump to be heated even more before going back to the pool.

Factors to consider

The solar collector must be installed on the roof of your home or shed or placed on the ground. Choose the location of the solar collector carefully so it can recover as much energy as possible. It can easily be installed in combination with a water heater or a heat pump. Before equipping your home with a solar collector system, make sure it complies with all municipal regulations.

Although a solar pool heating system is a good solution when it comes to heating your pool, it has some drawbacks:

• It takes longer to heat your pool on cloudy days (a water heater is useful on those days).

• The devices take up space on the ground or on the roof.

• Preparing your pool for winter is a more involved process.

On the other hand, you can get the most out of summer by enjoying a pool that is heated for free. It’s an option that combines both comfort and savings!

One tip: once you’ve finished swimming, use a solar pool cover to keep the water warm.
