The days of simply topping up with “any water” are over. Today: If you do without preparation, you open the door to problems for the technology in several places:<\/p>\n If hard water is filled in untreated, limescale deposits<\/strong> form when it heats up – preferably on heat exchangers, control valves and pipes. Rust forms in combination with ferrous materials. Even small amounts of dissolved oxygen are enough to cause material erosion and brown sludge<\/strong> in the heating circuit. Both too low and too high pH values have a negative effect on the system. The tolerance window quickly becomes critical, especially in mixed installations. Depending on the material, a range between 8.2 and 10 is recommended, and between 8.2 and 9 for aluminum.<\/p>\n Dissolved salts act as a “bridge” between different metals in the system – electrical potential differences and corrosion<\/strong> occur. The VDI Guideline 2035<\/strong><\/a> formulates clear specifications for the quality of filling and make-up water:<\/p>\n If you do not comply with these values, you risk losing your warranty<\/strong> – because most manufacturers base their conditions on these guidelines.<\/p>\n In practice, heating water is often treated as a “filling agent” – although it is the most important system component of all.<\/strong> Typical problem areas:<\/strong><\/p>\n In the event of damage, the heating engineer is responsible.<\/strong><\/p>\n Professional heating water treatment is not rocket science – it can be implemented efficiently and legally compliant with the right tools:<\/p>\n Use a digital measuring device<\/strong>, e.g. our WaterBoy<\/a>, to check the conductivity and pH value precisely.<\/p>\n Use full demineralization with mixed bed resin<\/strong> (e.g. Vadion pH-Control<\/a>) to remove all ions and achieve standard water values.<\/p>\n Use permanently installed make-up units with system separators in accordance with EN 1717 <\/strong>(e.g. our Heaty Complete Advanced<\/a> \/ PROfessional<\/a>) in order to have make-up water permanently under control.<\/p>\n Keep a system log at the customer’s premises<\/strong> with all measured values – this protects you in the event of a warranty claim and creates trust.<\/p>\n Heating water is not a side issue – it is an active operating resource.<\/strong> Featured photo: Adina Voicu<\/a>(Pixabay<\/a>)<\/p>\n","protected":false},"excerpt":{"rendered":" For all those who take responsibility for systems Modern heating systems provide more efficiency, more control technology, more comfort – but they have also become more sensitive.

\nSafe and standard-compliant operation is not possible without targeted heating water treatment.<\/strong><\/p>\nWhat happens without water treatment?<\/h2>\n
Limescale formation due to high water hardness<\/h3>\n
\nResult: efficiency drops<\/strong>, condensing boilers run inefficiently, pumps have to work harder.<\/p>\nCorrosion due to oxygen ingress<\/h3>\n
\nConsequences: magnetite sludge, clogged valves, blocked pumps.<\/p>\nIncorrect pH value = material attack<\/h3>\n
High conductivity = electrochemical risk<\/h3>\n
\nClassic example: Pitting corrosion on the aluminum heat exchanger despite apparently clean water.<\/p>\nVDI 2035 is not an option, but the standard<\/h2>\n

Why the topic is often underestimated<\/h3>\n
\nAfter all, what good is the best system technology if the water in it promotes corrosion?<\/p>\n\n
What you can do as a specialist company<\/h2>\n

Conclusion: Heating water determines function and service life<\/h3>\n
\nIf you ignore it, you risk a loss of efficiency, corrosion and breakdowns. Those who treat it ensure safe, long-lasting and low-maintenance operation.<\/p>\n
