Proper heating: 5 common mistakes and how to avoid them
In winter, it is important to heat your home effectively and sparingly. However, despite good intentions, many people make mistakes when heating, which not only hurt the wallet, but can also harm the environment.
This article lists the five most common heating mistakes and explains how to avoid them. In addition, tips are given on how to be more economical with heating and still achieve a comfortable room temperature.
If you take these tips to heart, you can not only save money, but also help protect the climate. This is because effective heating consumes less energy and therefore reduces CO2 emissions.
Read on to learn more about the most common heating mistakes and how to avoid them.
Disclaimer: The tips listed in this article are general in nature and may vary depending on your living situation and individual needs. Please consult an expert to get specific advice.
Mistake no. 1: Wrong airing
When heating, there are many mistakes that you should avoid. One of the most common mistakes is incorrect ventilation. Many people think that it is enough to open the windows a little to let in fresh air. However, this is a big mistake.

If you ventilate incorrectly, you lose a lot of heat and energy. The room temperature drops and you have to heat more to reach a comfortable temperature. This also increases the cost of heating and energy.
To ventilate properly, you should open the windows completely and let them air for 5-10 minutes. The stale air is exchanged and fresh, oxygen-rich air flows in. This is especially important when several people are in a room or when cooking or showering has been done.
- Open the windows completely
- Allow the room to be aired for 5-10 minutes
- Make sure that the humidity does not get too high
If you follow these tips, you can avoid the mistake of incorrect ventilation and heat effectively.
The mistake no. 2 when heating: overheating
A common mistake in heating is overheating rooms. Many people think that heating up the room quickly will result in faster heat buildup. But this is a misconception.
Because at too high temperatures the air in the room quickly becomes dry and uncomfortable. In addition, by doing so, you consume more energy than is actually necessary.

To avoid overheating, set the heating to a lower temperature and air the rooms regularly. A room temperature of about 20 to 22 degrees Celsius is recommended.
- Tip: It is best to use programmable thermostats to automatically regulate the temperature and save energy.
- Attention: Overheating can not only lead to an unpleasant indoor climate, but also trigger possible health problems such as headaches and circulatory problems.
Overall, it is important to find an appropriate approach to room temperature when heating to ensure both a comfortable atmosphere and energy-efficient heating.
Outdated heating system: a common mistake when heating
An outdated heating system is one of the most common mistakes in heating. Many people underestimate the importance of a modern heating system and stick to their old models. However, outdated heating systems can waste a lot of energy compared to modern systems, resulting in high heating costs and a poorer environmental performance. Therefore, it is advisable to regularly check the heating system and modernize it if necessary.
There are several ways to modernize an outdated heating system. A good option is, for example, the installation of condensing boiler technology. In doing so, the energy that is released when gas or oil is burned is no longer simply released into the air unused, but is converted back into heat and can therefore be used more efficiently. A heat pump or a solar thermal system can also be a sensible alternative.

- Conclusion: An outdated heating system can lead to high heating costs and a poorer environmental performance.
- Recommendation: Check the heating system regularly and modernize it if necessary.
- Options: Condensing technology, heat pump, solar thermal system.
Overall, it is important to look for good energy efficiency when choosing a heating system and invest in a modern system for that purpose, if necessary. An efficient heating system can not only save heating costs, but also protect the environment.
Problem no. 4: Insufficient insulation
As we know, effective insulation is an important factor in keeping heating costs down. However, if walls, windows or doors are not sufficiently insulated, a lot of heat is lost. As a result, the heating system has to work harder to keep the house warm, which leads to higher heating costs.
It is important to pay attention to good insulation when choosing windows and doors. Insulating walls can also pay off in the long run. It is also worthwhile to make sure that windows and doors close tightly to avoid unnecessary air circulation.
- Use windows and doors with high insulating capacity.
- Insulate your walls to minimize heat loss.
- Make sure that windows and doors close tightly.
By making sure you have adequate insulation, you can save energy and money while giving your home a comfortable temperature.
Proper heating: 5 common mistakes and how to avoid them
A common mistake in heating use is the incorrect use of radiators. Many people mistakenly think that by fully opening the radiator valves, they can warm up their home faster. However, this is a misconception.
To achieve a constant and comfortable room temperature, radiators must be vented regularly. This is the only way to prevent air from collecting in the heating circuit and reducing the heating output.
Another common mistake is the use of curtains or furniture that cover radiators. This prevents the heat from being properly distributed in the room. Make sure radiators are free of obstructions and heat can flow out freely.
If you wait too long before turning on the heating, it can take a long time for the apartment to warm up to a comfortable temperature. It is therefore advisable to use the heating regularly and continuously, and gradually increase the temperature in the home.
Another mistake is the use of heating in only one room of the apartment. A lot of energy is wasted. It is better to distribute heating evenly in all rooms and ensure that each heater, regardless of its size, reaches the correct temperature.
To maximize heating efficiency, you should also make sure the thermostat is set correctly. An incorrect setting can cause the room to become either too cold or too hot, wasting energy. Make sure the thermostat is set correctly and that it is checked at regular intervals.
