How to reduce the power consumption of your spa? When winter sets in and temperatures drop, there's no better way to relax than to immerse yourself in a spa and enjoy its jets! But be careful, because the electricity bill can quickly rise. According to the FFP ( French Federation for Pool and Spa professionals) the average cost of a spa is €200 per year for an indoor spa and €400 for an outdoor spa. However, with a few simple tips, you can reduce the final cost of your electricity bill. These are significant savings given the rising cost of energy.
To operate, a spa consumes electricity to heat and filter the water. Heating the water is the most energy-intensive part. On average, between 2,500 and 7,500 kWh per year are required for a 4-person spa.
The energy consumption of your spa depends on a number of parameters: the type and size of the spa, the choice of equipment and the adjustment of settings, and the period and frequency of use.
An indoor spa consumes less energy than an outdoor spa. This is because there is less difference between the temperature of the air in the room and the temperature of the water. For outdoor spas, install your spa in a sunny area so that the water heats up naturally.
Above-ground inflatable spas consume more electricity than built-in spas. Inflatable spas are better insulated and lose less heat.
Obviously, the larger the spa, the greater the volume of water that needs to be heated and maintained.
The power of the various pieces of equipment should also be taken into account: heating (electric heater), filtration (pump), jets system, etc.
If you use your outdoor spa in winter, it will consume more electricity to maintain the water temperature.
The water filtration system, while essential to maintain its balance, is also particularly energy consuming. Here is a reminder of the filtration time: you need to take the temperature of the water in °C and divide it by 2 to find the number of hours of filtration per day necessary for good water quality.
Keeping the water temperature constant at 39°C is certainly very pleasant, but it also increases your electricity bill. Don't hesitate to change the settings slightly, by adjusting the temperature to 37 or 38°C. Don't hesitate to consult your manufacturer's recommendations for use. Finally, some recent spas have an ‘energy saving’ mode that can also make a difference.
The massaging jets propel air to massage the body, but also help to lower the water temperature. The heat pump is therefore used more frequently to keep the water temperature constant. Use only the jets you need for your massage session and turn them off as soon as possible to use less electricity.
A filter that is not regularly maintained also contributes to poor water circulation and can also cause a chemical imbalance in the water. Regular filter cleaning avoids over-consumption of the filtration pump. Visit our tips to clean your spa properly
Recent spa models have well-insulated shells that prevent heat loss. However, without a protective cover, most of the heat escapes and the water evaporates. Investing in a good quality cover (thermal or with a thermal bubble, for example) will enable you to save between 2 and 5°C. You need to choose the cover according to the size of your spa, of course, but also according to your region: the colder or windier the region in winter, the greater the isothermal capacity of the cover. The recommended thickness of the thermal cover is 10 cm in the centre and 6 cm at the edges.
The insulation of your spa tank, and more generally of the enclosure, is very important for maintaining a constant water temperature. The better the insulation, the more the temperature will be maintained to avoid thermal bridging. These are the places where you will have a transfer of heat that results in the loss of a few degrees.
Some manufacturers offer high-performance insulation systems for the tank, but you can also improve your installation with insulating foam, which should be placed between the casing and the tank.
Follow these tips to reduce energy consumption when using your spa. This will save you money on your electricity bill and also help limit your ecological footprint on the planet.
