Low-H2O elements have a positive effect on your boiler on two different ways:
• The lower the water temperature, the more efficient your boiler becomes. Since Low-H2O elements are designed to work with Low- water temperatures, you can operate the condensing boiler always in condensing mode.
• Modern boilers have very compact heat exchangers which are vulnerable for stress caused by the temperature difference between supply and return water temperatures. Due to the fast reaction time, the return water reaches the operational temperature much faster. Therefore the difference between supply and return water temperature reduces very fast, preventing stress on the heat exchanger in the boiler.
