Only about 4 % of the drinking water consumed in germany per person per day is actually drunk or taken in with food. The remaining amount is used for showering, washing, rinsing and many other purposes.
What is good for the human being may not taste good at all for installations, household appliances and heating systems. How well-tolerated the drinking water is for the individual applications depends on its composition.
Just this much: the water constituents of the drinking water distributed in germany are as diverse as the country itself.
In order to treat the water according to its intended use, a professional analysis is essential. We offer you the necessary tools.
JUDO offers you a wide range of water testing equipment. Our range of products includes hardness measuring instruments, nitrate test sticks, iron and chlorine measuring instruments, pH test sticks, instruments for determining the total bacteria count as well as various pocket test instruments, analysis cabinets and analysis cases.
Untreated drinking water cannot always be used as heating filling and supplementary water. A planning of hot water heating systems according to EN 12828 always requires an analysis of the drinking water planned for use as heating water.
The drinking water ordinance does not specify any limit values for water hardness. However, german VDI 2035, Sheet 1 compares the four boiler groups, which are graded according to their output in kW, with guide values for carbonate hardness. For the sake of simplicity, the guide values are based on the total hardness in mol/m³.
Every component of a heating system must fulfil all intended properties at the latest at the beginning of the intended operation and be documented to the operator of the system. However, the condition of the heating water connecting all components is too often reduced to checking the fill level. Many damages to heating systems can be completely avoided, or at least detected at an early stage, by using simple measuring methods.
