I reduce my heating bill

06/05/22 - News

I set the temperature in each room correctly

I make sure that the temperature in the living rooms is always appropriate and not too high. If I lower the temperature by 1 degree, I can reduce my energy consumption by 6%.



Optimal temperature in degrees Celsius


Living room

20 °


17-18 °


22-23 °

I do not heat unused rooms: If I am not using a room, I remember to turn down the heating and close the doors to unheated rooms.


Attention: The radiators should not be covered by furniture so that the air can warm up well and the room can heat up; only then can the thermostat measure the temperature in the room correctly and regulate the heating.


I also remember to bleed my radiators regularly. The air has to get out so that the heat can circulate freely.

I ventilate the rooms properly

Quite often people ventilate by leaving the window tilted for a long time. But it is better to ventilate with the windows wide open, preferably with a draught, and only for a few minutes. This results in a rapid exchange of air without much heat loss, which improves the quality of the air.


With tilt ventilation, to have the same effect, I have to keep my windows open much longer to achieve the same effect for the air quality, but I cool down my room and especially the walls around the window at the same time. So the energy loss is all the greater.


At night it is also advisable to keep the shutters down to avoid additional heat loss.

Saving money at a low price

To make my life easier and save money, I buy programmable digital thermostats. With them, I can determine when which room should be heated. All I have to do is pre-programme the times and temperatures to easily save energy.


For example, if I only use the bathroom in the morning and evening, I set the thermostatic valve so that it is always pleasantly warm when I am in the bathroom - but only then. That way I avoid heating an empty room.


Digital thermostatic valves can also be operated remotely. So I can preheat my home via my smartphone before returning home.


I'm also thinking of insulating the boiler pipes in the basement. That way I don't lose unnecessary heat.

I have my boiler checked and thermography carried out

The environmental administration offers an energy assessment of heating systems in households, the so-called “Heizungscheck”. During this one-off inspection by a professional, I receive a comprehensive analysis of my boiler and recommendations on how to improve the energy efficiency of my heating system.


All information on heizungscheck.lu.


I can also have a thermography of my house done using a thermal imaging camera. This makes it easy to identify possible weak points in my house and energy losses. This way, I can take targeted measures to fix them, such as insulating certain areas of my house.

Klimabonus: Subsidies for heating systems based on renewable energies

In order to no longer be dependent on fossil fuels, I decide to have an alternative heating system based on renewable energies installed.

The state subsidy programme Klimabonus supports my efforts in this direction and offers me a number of subsidies and bonuses to not only have my old oil tank removed and replaced, but also to have a more environmentally friendly and economical heating system installed.
