Common Problems

This tankless water heater offers plenty of hot water without any fluctuation and remains trouble free for years. However, we suggest that you perform a food grade vinegar flush for one hour all over the unit at least once a year so that any sort of calcium or scale build-up gets eliminated. This tip is very helpful if there is hard water present.

You can easily run two showers simultaneously without any fear of cold water splashes because it comes with Advanced Flow Control technology. Go for it because this is a reliable water heater.
