coracon® heat transfer medium for heating water
No rust. No lime. No trouble.

Heating water as a heat transfer medium is one of the most important components of a heating system. If drinking water is simply filled into the heating system without appropriate treatment, this carelessness will pay off sooner or later. Over 90% of malfunctions and damage in heating systems result from incorrect heating water. Whether jammed valves, stuck pumps or muddy underfloor heating circuits. In most cases, the symptoms are due to untreated heating water. With coracon® heating protection products you safely prevent rust, limescale and other deposits.
