Just wondered why a gas safe engineer would sign off someone else's work when it's illegal to do so. And one other point. Most people who slag off gas fitters can't pass the exams required. Fact.
Has any other fitters had many probe with ferolli boilers as me. Fitted over100. Get non stop boiler faults after about 1 year. Leaks fault codes and heat exchanger defects
I am a heating engineer. , have any other fitters had as many problems with ferolli boilers. They have installed. I've fitted over 150. And had problems with at least 90. It's very embarrassing with customer complaints and ferroli are not very helpful atall
