This is the new version of the UP15-14B, it is the same with a few modifications, new for old replacement.
All COMFORT pumps – with or without the autoadapt function – combined with a return pipe deliver instantly
hot water all over the house. This eliminates the expensive – and annoying – wait for the water to get warm and
reduces the annual consumption of domestic water. Theresults are lower costs while still ensuring the comfort of
instantly hot water.
