Water Balance


Important - If you do not pay due regard to -Water Balance' and regularly test your pool water with a good quality water testing set then you may suffer a damaged Heat Exchanger inside or outside your boiler, either through clogging up (excessive scaling) or corrosion by too much acid. This also invalidates warranty. See our Water Treatment section for our water testing set. This
applies to all Certikin Heaters.


Operating Through The Winter
Due to condensation boilers required to operate throughout the winter should not be installed outdoors.
