  1. works like a horse

    Posted by Unknown on 16th Feb 2015

    This heats an in floor heating system with Wirsbo/Pex tubing, 13 thermostats, and heats hot water. I had the series 1 and I forgot to maintain it since new so it needed a new heat exchanger in 15 years. Otherwise, really was impressed with this and replacing it with a new one.
