A boiler service extends the
service life of your boiler
many times over   

With our boiler descaling service,

not only is the boiler descaled without chemicals, it is also protected against corrosion.
We carry all spare parts such as seals, anodes and heating elements in our service trolley.

We advise you personally and determine the service interval individually

Calcification deposits reduce
the efficiency 
of your boiler  
Calcification
An average four-person household uses around 250 liters of hot water every day for the kitchen, bathroom and personal hygiene. Extrapolated over a year, a boiler therefore produces around 90,000 liters of hot water. After three years, around 300,000 liters of water will have passed through the boiler. For hygienic reasons alone, the boiler should now be serviced.
Sand, sludge or other foreign particles have been washed in with all the water and have settled in the "boiler sump". They form an ideal breeding ground for bacteria.
   
The following examples show that limescale in particular has also built up inside the boiler during this time. Scaling depends on various factors. For example, the hardness of the water, the operating temperature and, above all, the heating system and hot water consumption. Increasing limescale build-up leads to increased energy consumption, reduces the performance of the boiler and, in serious cases, can lead to interruptions in operation and even destroy the radiator.

Corrosion is the bigger problem
than calcification, as it is usually
only discovered when damage
has already occurred.

The anode is the corrosion protection of the boiler.
The example shows anode degradation over time.

    
Corrosion (rust)
As a mixture of different types of water (spring, ground and lake water) is increasingly being used for water supplies, the high oxygen and carbon dioxide content in the water is leading to more and more signs of corrosion in the boilers.
   
In enameled boilers, for example, the different expansion of the steel and the enamel causes fine hairline cracks in the enamel, which are subject to more or less rapid corrosion. To prevent the corrosion effect and extend the service life of the boiler, one or more anodes made of a magnesium alloy are fitted in the tank. The magnesium of this anode has a markedly negative electrochemical potential in relation to that of the other metals in the appliance.
   
When there is an anode in the water heater, the corrosive effect of the water is directed to the anode, whose material is slowly consumed. This is referred to as cathodic corrosion protection because the magnesium protective anode protects the cathode, i.e. the steel boiler.
    
Nowadays, almost all boilers are enameled and equipped with magnesium protective anodes. This allows the natural aggressiveness of the water to be corrected. Plasticized and cemented boilers, chrome steel boilers and even black steel boilers can also be cathodically protected against corrosion with the magnesium protective anode and also have a positive effect on the limescale structure.

Solar systems The company Berger Boiler-Service has been in existence since 1992.
Our core competencies are the maintenance of
boilers as well as the construction and maintenance of solar systems.

We have
been successfully active in the field of solar systems for 15 years.

We have many years of experience in the
installation of solar systems.
