Interesting hints from practice
On this page we have collected some tips and background information for you, for instance on the fuel consumption and corrosion subjects.
Tip 1: Optimal heating with clean boilers
Just a few millimeters deposits in the boiler increase fuel consumption by 8-13%. Take a look at your heating boiler! Check the deposits - and read the percentage of fuel oil you can save in the table.
Our recommendation: Sotin heating boiler cleaner
It cleans boilers quickly and thoroughly and protects the environment.
1st step: Turn off the burner and open the heating boiler room.
2nd step: Spray the boiler dirty inner surfaces with Sotin heating boiler cleaner and let it briefly work. Then heat the boiler. Afterwards, the strongest soot and sulfate deposits will be removed. The boiler surface will shine and can optimally transfer heat again.
3rd step: After cooling, re-open the heating boiler and vacuum the residues lying on the boiler bottom with the soot cleaner (e.g. Sotin NT2). That's it.
TIP 2: Corrosion test for heaters
Heating water test - in just 3 minutes a reliable diagnosis
Fill a transparent container with the fluid of any heating element included in the heating system.
Background information on the subject of corrosion
Corrosion is the decomposition of metals and alloys by chemical and electrochemical processes.
A chemical attack is mainly due to the oxygen in the water; but also carbon dioxide and, especially in industrial areas, the sulphur dioxide and sulphuric acid in the air have a highly corrosive action. The smoother the surface, the less aggressive the chemical attack.
Electrochemical attack is caused by the formation of galvanic elements. If two metals with different electrical potential come into contact with each other conductively (zinc rain gutters on a copper roof, iron rivets on aluminum), the less noble metal will dissolve. This phenomenon can also occur in the heating system when different metals are present.
Tip 3: ph-value and water hardness
Calcium and magnesium components, present in water as largely dissolved, are responsible for overall water hardness. These components decompose when water is heated and form the dreaded scale. As a unit of measurement for water hardness applies the German degree of hardness, °dH shortly. One °dH is equivalent to 10 mg/1 l water.
Water hardness in °dH and water description
Water hardness 0–4: very soft
Water hardness 4–8: soft
Water hardness 8–20:hard
Water hardness above 20: very hard
