Vaillant were once the market leaders in Combi boilers but not any more. If You own one of the Ecotec range, You are in for trouble. They have made so many mistakes with these boilers it,s difficult to believe. Burst hoses, failed cheap pumps. When you come to change the pump the whole assembly has to come out because the new pumps won't fit.Even the burner seals failed and melted other internal components. That's if you didn't experience the screaming sounds coming from the wrongly sizes air intake which usually happens just before the pressure sensor fails.Good luck if you have one of these boilers....you'll need it.
