Why is leaving the heating “on minimum” a mistake? 5 tips to save in winter
Discover the truth about the efficient use of heating and save on your gas bill
With the arrival of winter, the real challenge for many homes in Spain is to manage heating consumption, especially when the cold hits. Many believe that keeping the heating on “to a minimum” is an effective way to keep the house from getting cold and reduce costs. However, HVAC experts point out that this strategy can be counterproductive.
The myth of minimal heating
The belief that leaving the home heating on at low power is enough to maintain a warm environment has become common, but scientifically disproved. Keeping a heating system operational for long periods, even at low temperatures, considerably increases energy consumption. Specialists suggest that the key is to turn on the system only when we really need it.
“Turning off the heating when we are away or at night consumes less energy than keeping it running all the time,” indicate sources from the National Center for Environmental Education (CENEAM).
Factors affecting energy consumption
In Spain, the increase in gas prices has led many families to look for alternatives to save on their bills. Most homes use conventional or condensing boilers, which are less efficient. Therefore, understanding how energy consumption in heating really works is essential.
Practical tips for efficient use of heating
- Heating progresses: Adjust the temperature in different time zones, using your heating settings so that it only works when you are home.
- Suitable temperature: The ideal temperature for the environment is between 19 and 21°C. Each additional degree can increase energy consumption by 5% to 10%.
- Use thermostats: Installing programmable thermostats that automatically adjust the heating around your schedule can make a big difference.
- Isolation: Improves the insulation of doors and windows to avoid unnecessary heat loss.
- Zone heating: Turn off the heating in rooms you don't use. This optimizes consumption and reduces the bill.
The voice of the experts
The industrial engineer and expert in renewable energies, Jorge Morales de Labrahas described as an “aberration” the idea that keeping the heating running at a minimum is a smart investment. According to Morales, “turning on the heating only when necessary is the best strategy to avoid increasing the bill and reducing the ecological footprint.”

By following these tips and rejecting myths such as leaving the heating on at minimum, you will not only be able to reduce household expensesbut also contribute to a more responsible use of energy resources in the community.
Social and economic impact
The increase in gas rates has led many families to a situation of economic vulnerability. **Energy efficiency** is not only a matter of personal savings, but has a considerable impact on the country's economysince access to energy is a fundamental right that affects everyone.
Relevant data on consumption
| Situation | Power consumption | Approximate cost (monthly) |
|---|---|---|
| Heating on 24 hours | 1500 kWh | €180 |
| Heating on only 8 hours | 400 kWh | €50 |
Reactions of citizens
The experts' statements have sparked an intense debate among citizens about the culture of energy consumption. Many are beginning to rethink how they use heating and look for more sustainable alternatives, while others are still wary of conventional advice. What do you think about this controversial topic?
With winter just around the corner, implementing these tips can be key to keeping warm at home without skyrocketing bills. Energy efficiency not only translates into savings, but also a healthier environment.
