Boiler-cleaning - Effect of deposits on oil consumption

Self-acting, permanent sealing of leaks


Only clean boilers heat optimally!
Even a few millimetres of deposits in the heating boiler increase the fuel consumption by 8-13%. Take a look in your heating boiler! Check the deposits - the table will tell you the percentage of fuel oil you could save.

Sotin Boiler cleaner - cleans heating boilers fast and thoroughly and is kind to the environment

We recommend following procedure:

1. Switch off burner and open combustion chamber.
2. Thoroughly spray the soiled interior heating boiler surfaces with Sotin Boiler cleaner and leave for a short while.
Then heat the heating boiler thoroughly. This will remove even the most stubborn soot and sulphate deposits. The burner will have a steel-bright surface, allowing optimum heat transfer.
3. Once the burner has cooled down, open the combustion chamber again and remove any residues from the boiler bottom using a vacuum cleaner (e.g. Sotin NT 2). Ready.

The heating water test - 3 minutens for a safe "diagnosis"

Fill water from any radiator within the heating system into a transparent container.

Clear water indicates that no corrosion is present. To ensure that this remains the case, you should add Sotin K 20!This amount of clouding indicates advanced corrosion! The complete heating system must be cleaned and subsequently protected. - look at our catalog "Heating system protection"

Corrosion
Corrosion means the decomposition of the metals and alloys through chemical and electro-chemical processes.
The chemical attack is to be put down above all to the oxygen in the air; but also the carbon dioxide and in particular, in industrial areas, the sulphur dioxide and the sulphuric acid in the air have a strongly corrosive effect. The smoother the surface, the less the chemical attack.
The electrochemical attack is caused by the formation of galvanic elements. If two metals with differing electrical potential come into contact with one another in a conductive way (zinc rain water pipe on copper roof; iron rivets on aluminium), the less precious metal will dissolve. This phenomenon can also occur in a heating system if a number of metals exist.


The pH value
The pH value states whether a watery solution (e.g. cleaner) or water behaves in an acid, alkaline or neutral way. The pH value is stated from 0  to 14. pH value 7 is neutral.


Hardness of the water
The calcium and magnesium bicarbonates dissolved in water, carbonate hardness CH (temporary hardness) and calcium – magnesium – sulphates – chlorides – nitrates – phosphates (non-carbonate hardness NCH) (permanent hardness) are responsible for the overall hardness of water. The carbonate hardness CH parts decompose when the water is heated and form the feared "limestone".
The unit of measure for water hardness is the "German degree of hardness" (°dH).
One °dH corresponds to 10 mg hardness former/1 litre of water.

 
Water hardness in °dH    Designation of the water
0 - 4 very soft
4 - 8 soft
8 - 20 hard
above 20 very hard

 


Decalcifying

See catalog chapter "Decalcifiers · Decalcification Pumps" for details.


Self-acting, permanent sealing of leaks.

Self-acting, permanent sealing of leaks in heating boilers, gas water heaters, boilers, heat exchangers, radiators, underfloor heating systems, piping (also concealed), containers and other water-based systems.
