Owning a swimming pool brings relaxation and fun during the hot summer months. Even if it is possible to enjoy it in winter, the question of energy consumption arises.

Owning a swimming pool brings relaxation and fun during the hot summer months. Even if it is possible to enjoy it in winter, the question of energy consumption arises.  
Several solutions are possible and we detail them below :
Filtration pumps  
For the filtration of your water, opt for a variable speed pump which will be your best ally in reducing your electricity bill.  
They have many advantages: 

  • Thanks to the multi-speed motor, they adapt their filtration speed to the needs of your pool (hot or cold periods) 
  • Lower electricity consumption during low flow filtration 
  • Better filtered water thanks to its gentle passage through the filter 
  • Longer service life  
  • More pleasant sound level depending on the parameters you have programmed  

In addition to being economical, variable speed pumps are also more environmentally friendly than conventional pumps. 
Better filtration also reduces the consumption of pool water treatment products. 

Heat pumps
The majority of heat pumps consume a lot of energy, particularly because of their constant power. There are now pumps with "inverter" technology. 
There are two types of pumps:  

  • The "simple inverter" heat pump, which guarantees a variation in power depending on when you need the most heat, for example. 
  • The "full-inverter" heat pump, which will also vary the speed of the compressor to ensure constant heating of your pool.

Their advantages are both economic and ecological. 

Covers and shutters 
During the hot summer months, it is not uncommon for the water level in your pool to drop. In order to keep the water level more or less constant, we recommend that you install a cover that will limit the evaporation of your water. 
In mid-season, covering your pool also helps to maintain the water temperature of your pool or to limit the drop in water temperature. 
There are different models with different characteristics:  

  • The bubble cover: will both prevent your water from evaporating and heat it up thanks to the bubbles on the surface which will create heat thanks to the sun's rays. This will limit the use of the heat pump. 
  • The winter cover: more resistant than a summer cover, it will be able to support the weight of the rainwater and will contribute to the protection of your water. Thanks to its UV protection, it will limit the proliferation of algae during its hibernation period. At the same time, it ensures the safety of your animals or children thanks to its superior strength. 
  • The flap: more expensive but easier to install, it will be your ally in protecting your water from dirt. Electric or manual, it also allows you to keep the pool warm. The electrical system that controls the cover makes it easy to put in place and will help you in your winterization process.  

The cover will also be your ally in limiting the waste that can be found at the bottom or on the surface of your pool (leaves, insects, etc.).  

Your lights  
Swimming pools regularly have projector lights to illuminate the pool at night. As with outdoor pools, the use of LEDs is to be favoured as they consume less energy than floodlights.  
They are however an investment to buy but their advantages are numerous: 

  • Low energy consumption 
  • Lifespan of approximately 20,000-25,000 hours compared to 1,000 for a conventional bulb  
  • Quick changeover from conventional bulbs to LED bulbs  
  • LEDs do not heat up so there is no risk of injury underwater  

The purchase price is quickly recovered thanks to their very low consumption which will reduce your electricity bill.
