Healthy heating tips

Tips & tricks

Heating correctly not only provides a comfortable room environment, but also reduces environmental pollution and the pressure on your budget. You should bear the following tips in mind:


Did you know that every extra degree of room temperature requires 6% more energy? Each room should only be heated to the extent that it is used. Living areas are normally kept at about 21 °C, whereas kitchens and bedrooms are a little cooler, approx. 18 °C.


Ventilation can result in a great deal of heat loss. As a result, ventilate several times briefly and intensively by opening the windows wide for about 5 minutes. Continuous ventilation, for example by tilting the windows, does not provide the necessary exchange of air and wastes energy.


Depending on the level of insulation in the house, the room temperature should be lowered by two to five degrees during the night. Switching off would be counter-productive, because reheating the cooled rooms takes much more energy than is required for continuous heating at a low level.


Radiators should be free-standing to allow the heat to spread around the room quickly. Putting pieces of furniture in front of them or covering them with long curtains has an unfavourable effect since they absorb the heat.


Air that enters radiators prevents water from circulating. The familiar glug-glug noise is a certain sign that there is air in the heating circuit. Another reliable warning signal is if the radiator does not heat up properly. In most cases, it is very simple to bleed the radiators yourself.
