As fall is fast approaching and the price of electricity and gas continues to rise, some are thinking of lowering the thermostat to save money. But is it beneficial?

The video of the day :

Belgians spend an average of €1,400 per year on heating. But that was without counting on the inflation caused by the war in Ukraine and the surge in energy prices. While some lucky people still benefit from the old tariffs thanks to their fixed rate, others have seen their energy bill take a big leap. However, when you look at your energy bill, you know that heating comes first. It is therefore often suggested to lower the temperature by a single degree in order to make considerable savings. What is it really?

Save up to 7%

7% is the savings you can make on your annual consumption if you lower your thermostat by one degree and avoid overheating certain rooms. This without impacting your comfort, explains the website. Moreover, if you do not have one, investing in a programmable thermostat will allow you to make great savings by regulating the interior temperature according to each room and each need. In total ? Nearly 20% energy saved, a non-negligible gain. Heat only the rooms you occupy and close the doors to rooms you don’t heat are things that go without saying, but should also be remembered.

Which temperatures do you prefer?

It is estimated that, on average, the comfort temperature of a house is around 20°C. The minimum recommended temperature is 16°C. Lowering the temperature of your home further could be counterproductive, because the heating will have to operate at full speed before returning to a pleasant room temperature. For short absences, we recommend lowering the heating to a minimum of 16°C, for prolonged absences, we recommend 12°C instead. Below, the risk of humidity and therefore of mold is increased. Another technique is to switch to night mode an hour before you leave your home or go to bed, since the heat will stay in the house long enough to keep you warm.

Maintain your heaters and boiler

More generally, maintenance is the key to avoid over-consumption. It is advisable to purge your radiators at least once a year, before the onset of winter. They are also cleaned regularly to prevent dust from accumulating. Ditto for your boiler. Whether it runs on gas, oil or wood, maintenance is not only legally required, but it is also essential to avoid any overconsumption of energy.

Invest in an efficient installation

Finally, good insulation is essential to really reduce its consumption. In Brussels, old buildings unfortunately have poor insulation of the walls, floor, windows and sometimes even the roof. “Reinforcing the insulation of your house or apartment is certainly an important investment at the moment, but which will allow you a good long-term profitability”, explains Loris Taillard, architect. Moreover, Energy and Renovation grants are granted in the various Regions of Belgium.

It is also estimated that a conventional boiler has a lifespan ranging from 10 to 20 years. The older it is, the less efficient it will be, with a higher bill as a bonus. “To replace it and obtain a more productive and less energy-consuming output, we opt for a condensing boiler or systems operating using renewable energies, such as heat pumps or pellet boilers”he advises.
