"Great unit"
Since the UFT is part of HTP's line up, we installed over a hundred of these units. Mostly heating with indirect dhw. All units have been installed according to installer's manual with combustion analysis at initial startup. We had 3 warranty claims, 2 of them were the gas leak sensor and the other one was a faulty card. For residential application, it is a good, reliable boiler. As long as the pump is sized properly, a magnetic dirt separator is installed and vent length is respected it will run great.
