does conductivity mean in heating water?"},"content":{"rendered":"<p>Conductivity is one of the key parameters in <a href=\"https:\/\/uws-technologie.de\/en\/what-happens-if-heating-system-water-is-not-treated\/\">heating water<\/a>\u2014and at the same time one of the most commonly misunderstood.<\/p>\n<p>It is often viewed merely as a measured value.<br \/>\nA numerical value that is recorded without its actual significance for system operation being fully understood.<\/p>\n<p>But there is much more to conductivity than that.<\/p>\n<p>It is a direct indicator of how \u201cactive\u201d the water in the system is\u2014and thus how high the risk of <a href=\"https:\/\/uws-technologie.de\/en\/what-influences-corrosion-in-heating-circuits\/\">corrosion<\/a> and consequential damage is.<\/p>\n<h3>What conductivity actually describes<\/h3>\n<p>Conductivity indicates how well water can conduct electricity.<\/p>\n<p>Pure water conducts almost no electricity.<br \/>\nIt only becomes conductive through dissolved substances\u2014especially salts.<\/p>\n<p>It is precisely these dissolved ions that are crucial in the heating system.<\/p>\n<p>They usually come from:<\/p>\n<ul>\n<li>Drinking water during initial filling<\/li>\n<li>Make-up water during operation<\/li>\n<li>Residues and reactions within the system<\/li>\n<\/ul>\n<p>The more of these substances are present in the water, the higher the conductivity.<\/p>\n<p>And this is precisely where the real problem begins.<\/p>\n<h3>Conductivity as a driver of electrochemical processes<\/h3>\n<p>Increased conductivity does not merely mean \u201cmore dissolved substances\u201d.<br \/>\nIt actively changes the conditions within the system.<\/p>\n<p>This is because as conductivity increases, water becomes a better electrical conductor\u2014and thus the basis for electrochemical reactions.<\/p>\n<p>These reactions are the driving force behind corrosion.<\/p>\n<p>Metals in the system interact with the water.<br \/>\nThe better the flow of electricity, the more easily these processes can occur.<\/p>\n<p>The result is gradual material degradation that develops over long periods of time.<\/p>\n<p>Conductivity is therefore not a neutral measurement, but a direct factor influencing the likelihood of corrosion.<\/p>\n<h3>Why high conductivity is problematic<\/h3>\n<p>In practice, the following is repeatedly observed:<br \/>\nThe higher the conductivity, the more unstable the system becomes.<\/p>\n<p>This is because several effects occur simultaneously.<\/p>\n<p>On the one hand, the likelihood of corrosion processes increases.<br \/>\nOn the other hand, the chemical equilibrium in the water changes.<\/p>\n<p>In the long term, this leads to:<\/p>\n<ul>\n<li>increased material dissolution<\/li>\n<li>formation of corrosion products such as <a href=\"https:\/\/uws-technologie.de\/en\/everything-you-need-to-know-about-magnetite-separators-why-they-are-indispensable-for-modern-heating-systems\/\">magnetite<\/a><\/li>\n<li>deposits and malfunctions<\/li>\n<\/ul>\n<p>The situation becomes particularly critical in systems with different materials.<br \/>\nHere, even moderate levels of conductivity can be sufficient to promote undesirable interactions.<\/p>\n<h3>The gradual increase during operation<\/h3>\n<p>A point that is often underestimated:<br \/>\nConductivity does not remain constant.<\/p>\n<p>Even if the system was initially filled correctly, the value changes during operation.<\/p>\n<p>Causes of this include:<\/p>\n<ul>\n<li>regular makeup water<\/li>\n<li>oxygen ingress<\/li>\n<li>material reactions within the system<\/li>\n<\/ul>\n<p>With each of these changes, new dissolved substances enter the water.<\/p>\n<p>Conductivity increases\u2014often unnoticed.<\/p>\n<p>And just like with other processes in the heating system, this does not happen suddenly, but gradually.<\/p>\n<p>The system continues to run while conditions in the background are constantly shifting.<\/p>\n<h3>Conductivity in the context of overall water quality<\/h3>\n<p>Important:<br \/>\nConductivity must never be considered in isolation.<\/p>\n<p>It is always related to other parameters, in particular:<\/p>\n<ul>\n<li>the pH value<\/li>\n<li>the materials used<\/li>\n<li>the system\u2019s operating conditions<\/li>\n<\/ul>\n<p>A specific conductivity value may be uncritical in one system, while it may already be problematic in another.<\/p>\n<p>This is precisely why blanket limit values often fall short in practice.<\/p>\n<p>The interaction of all influencing factors is decisive.<\/p>\n<h3>Why measurement alone is not enough<\/h3>\n<p>Conductivity is relatively easy to <a href=\"https:\/\/uws-technologie.de\/en\/avoid-sources-of-error-correctly-measuring-documenting-and-calibrating-heating-water\/\">measure<\/a>.<\/p>\n<p>But the measured value alone does not solve the problem.<\/p>\n<p>It merely indicates the current state\u2014not the cause, nor the necessary action.<\/p>\n<p>It is only within the context of a systematic approach that the measurement becomes truly valuable.<\/p>\n<p>This is where a structured approach comes into play.<\/p>\n<h3>The UWS Quartet as a Practical Solution<\/h3>\n<p>In practice, the UWS Quartet has established itself as a clear framework for effectively managing conductivity.<\/p>\n<p><strong>It starts with measurement.<\/strong><br \/>\nConductivity is recorded and evaluated.<\/p>\n<div class=\"one-col-produktbox\"><div
