Pool Guide

Why does an automatic cover save energy?

Pool owners have to deal with several factors that increase energy consumption:
- Evaporation: An uncovered pool loses several litres of water per day, which means that it has to be constantly topped up and therefore consumes more energy.
- Heat loss: Water naturally heats up in the sun, but without protection, the heat is quickly dissipated, requiring more frequent heating.
- Intensive use of the filtration system: A swimming pool exposed to impurities requires a longer filtration time to keep the water clean.
An automatic cover acts on these three elements by limiting evaporation, conserving heat and reducing the accumulation of debris, which reduces the need for filtration and maintenance products.

1. Reduction of evaporation and water requirements

Evaporation is one of the main factors in water loss in a swimming pool. The larger the pool and the more exposed it is to the wind and sun, the greater the evaporation. By covering the pool after each use, an automatic cover prevents this evaporation and limits the need to refill.
Advantages:
- Less water lost on a daily basis.
- Reduced water consumption, particularly useful in times of restrictions.
- Stability of chemical products, requiring fewer additions to maintain the water balance.

2. Heat retention and reduced heating requirements

Maintaining a comfortable temperature in a heated swimming pool represents a significant energy cost. The use of an automatic cover reduces night-time heat loss and prevents the water from cooling down.
Concrete effects:
- Maintains a stable temperature between 3 and 5°C higher than an uncovered pool.
- Reduces the energy consumption of heat pumps or electric heaters.
- Optimisation of bathing periods with naturally warmer water.

3. Reduction of filtration time and maintenance costs

Impurities that fall into the water (leaves, insects, dust) force the filtration system to work longer. An automatic cover prevents these elements from entering the pool, thus reducing the workload of the filter. Impact on filtration: - Less filter cleaning and therefore a longer lifespan. - Less electricity consumed to operate the pump. - Fewer disinfectants needed thanks to better protected water.

The different types of automatic covers and their energy impact

There are several types of automatic covers, each with a different impact on energy conservation.

1. Roller shutters

Roller shutters are made of PVC or polycarbonate slats that float on the water. The transparent polycarbonate models can even capture and restore solar heat.
Advantages:
- Excellent temperature retention.
- Optimal protection against evaporation.
- Compatible with heated pools.

2. Bar covers

These covers combine a reinforced tarpaulin with rigid crossbars that provide enhanced safety. They also protect against heat loss and evaporation.
Advantages:
- More affordable than a roller shutter.
- Good thermal protection and safety.
- Easy to install and use.

3. Automatic solar covers

These covers use bubble or polycarbonate technology to capture the sun's heat and transfer it to the water.
Advantages:
- Heats the water naturally, reducing heating costs.
- Very effective at retaining the heat accumulated during the day.
- Easy to install and compatible with most swimming pools.

Investment and profitability: what is the return on investment of an automatic cover?

Although the installation of an automatic cover represents a significant initial cost, it allows for substantial savings in the long term:
- A reduction in energy consumption of up to 50% on heating.
- A 30% reduction in spending on chemicals thanks to better protected water.
- A reduction in filtration time, thus reducing the electricity bill.
Over a period of 5 to 10 years, these savings more than offset the initial investment, while offering increased comfort and safety.

How do I choose the right automatic cover to maximise energy savings?

To get the most out of your automatic cover, it is essential to choose a model that is suitable for your pool:
- For a heated pool: Opt for a polycarbonate roller shutter that absorbs the sun's heat.
- For an unheated pool: An automatic solar cover will help to raise the water temperature naturally.
- For a cost-effective solution: A slatted cover offers a good compromise between price and energy efficiency.

Essential equipment for a more environmentally friendly swimming pool

Investing in an automatic cover not only makes the pool safer, but also saves significant money by limiting evaporation, conserving heat and reducing the use of the filtration system. In a context where energy and water management is becoming a priority, this equipment represents a sustainable and cost-effective solution for pool owners.
By choosing a model suited to their needs and using it systematically, every pool owner can reduce their environmental impact while optimising their pool maintenance costs.
