PDF Demineralized water and corrosivity

Why use demineralized water for your heating system Closed-loop hydronic systems are consistently observed to self-alkalinize. This means that pH naturally rises above 8.2 under normal conditions. Similarly, closed-loop hydronic systems naturally stabilize their conductivity levels to within 32-64 ppm TDS (50-100 μS/cm).

The Closed System | | DIY Radiant Floor Heating | Radiant

As you can see, this allows the boiler to heat a tank of potable water, which in turn can provide domestic hot water AND floor heating (in an "open" or "closed" configuration). The water from the boiler to this heat exchanger flows 24 hours a day in a closed loop, making the heat exchanger "continuously active" (i.e. always hot).

3 Introduction Hydronic heating or cooling systems use water as the means for carrying heat from one point to another. They are becoming more complex as they grow in capacity, and as control methods become more sophisticated. Small systems may still use a single pump, but it now serves several different temperature zones: low temperature radiant systems, higher temperature supplemental heat
