Heating ducts should be cleaned

Clean heating - better heating performance and a good indoor climate

Often little attention is paid to radiators when cleaning - apart from the superficial removal of dust, not much usually happens. You should also clean your heater regularly, depending on the type of heating. This is not only worthwhile for hygienic reasons, but also to permanently improve the heating performance. We explain below what you should pay attention to when you want to clean your radiator.

Why should you clean your heater?

Over time, dirt, lint and dust will collect in and on the radiator. These tend to nestle in the slats and grooves. This affects the performance of the heating in two ways:

First of all, the layer of dust on the surface of the radiator insulates the heat and thus reduces the heating output. Over time, particles can even burn themselves in, so to speak, and permanently impair the heat output of the heating system. In the long term, poor heating performance then also leads to higher energy costs.

At the same time, switched-on radiators in the interior also function like a circulation pump and influence the room climate. Deposited dust is whirled up and distributed in the room air. This way, dust quickly spreads back onto furniture and decorative objects. In addition, you inhale more fine dust, which can be problematic for allergy sufferers. In general, a high level of fine dust pollution ensures drier air, which has a negative effect on mucous membranes.

It is therefore worth cleaning radiators in order to save heating costs on the one hand and to achieve a better indoor climate and the optimal room temperature on the other.

Info: A lot of dust is often deposited on radiators. If the air warms up, dust and dirt particles rise, the air cools down again, and these are deposited on the radiator. In the lamellas in particular, this sticks more quickly.

What do you need to clean radiators?

Depending on the radiator, it is usually sufficient to clean with a feather duster, a duster or a vacuum cleaner with a suitable attachment. Alternatively, special radiator brushes are also available. To remove dirt, you can use most conventional household cleaners and apply them with cleaning or sponge cloths and soft sponges.

Danger: The household cleaners should be suitable for painted surfaces. To avoid discolouration, the cleaning agent can be applied to a small area on the radiator and the effect can be tested.

Avoid using abrasive sponges and abrasive cleaners to avoid dulling the paint or creating scratches in the paint.

Info: If you want to clean yellowed radiators, it is not necessarily necessary to paint them. Alternatively, yellowed areas can be covered with spray paint or cleaned with oven spray, but this can also damage the paint

Prepare for cleaning

Before you declare war on dust and dirt, you should make a few preparations. Proceed as follows:

  • Switching off the heating: Switch off the heating a few hours before cleaning to avoid burns if it comes into contact with the radiator
  • Clear the radiator: Make sure that the radiator to be cleaned is easily accessible
  • Cover the floor: To prevent dust and dirt from spreading again in the apartment, you should cover the floor under the heater. The following are suitable: tarpaulins, damp cloths or old newspapers

How do you clean radiators?

Once everything is set up, you can start cleaning. It is important that you not only clean the surface, but also clean the interior of the radiator. To do this, the radiator cover usually has to be removed from panel radiators. Most radiators have the grille on the top or on the side. This can either be removed easily or by loosening the screws. This is not necessary with ribbed and tubular radiators, but the spaces between the lamellas should be cleaned thoroughly.

Time required: 30 minutes.

Then do the following when you want to clean a radiator:

  1. Vacuum interior

    Use a flat-top vacuum cleaner to vacuum the inside of the heater to remove dust and loose debris

  2. Clean gaps

    Use the radiator brush, dust cloth or a feather duster to thoroughly clean the gaps, grooves or slats. If necessary, a special flap brush can also be helpful

  3. Cleaning surfaces

    Clean the surfaces of the heater with detergent. A certain exposure time may be necessary

  4. Remove dirt from the grid

    Rinse the grille or cover in the bathroom and also remove dust and dirt from the grooves of the grille

Info: It is worthwhile to clean heating systems regularly. Both the exterior and interior should be cleaned at least once or twice a year. The times before or after the heating season are best.
