How to properly clean a solid fuel boiler?

The boiler, which gives us warmth and comfort at home, especially during the winter months, also needs proper and regular maintenance. Daily use of the boiler creates dust, soot and tar, which must be cleaned. In this article, you will learn why boiler cleaning is important, what is at risk if you neglect the boiler and how to proceed when cleaning different types of boilers.

Why is it important to clean the boiler?

Failure to clean and neglect maintenance of the boiler can mainly result in reduced efficiency, sometimes up to 25 percent. Reduced efficiency means higher operating costs and more frequent heating. In the worst case, by not cleaning the boiler, the inside gets tarred so that the boiler can lose its service life by several years.

How to proceed with cleaning?

First of all, we wait until the boiler cools down. The cleaning process with original accessories can take about 5 minutes. Solid fuel boilers can be divided into three groups according to cleaning.

Wood boiler

We start by cleaning the loading chamber. Clean the sides of the chamber and collect the ash through the nozzle into the ashtray using a rolling pin. Scoop out the ash from the lower part of the ashtray using a collection shovel into the collection container. We will not forget to clean the side areas next to the ashtray.
We clean the turbulators and the lower part under the heat exchanger once every 3 days, depending on the intensity of use.

Combined boiler

With this type of boiler, in which it is possible to use both fuels (wood or pellets), the cleaning process is almost the same. However, it is not necessary to clean the burner when using pellets. The automatic Pellet burner cleans itself after burning out by extending and retracting the grid. When burning pellets, the ash is finer than when burning wood.

Pellet boiler
