Thank you Sam. Reading and passing it and practically doing it as a profession are 2 different things.You have gathered your experiences over the years.You didn't know everything about boilers the day you qualify?..You have failed in some aspects and asked questions no matter how stupid they may sound. So that is the courage people get to join a group like this. When you are taken on by a company to do 8 services/safety check a day.. it's a different ball game. Time and pressure. Little things you know before begin to disappear. You dont want to let yourself down.
Many of us who's been qualified over 10 years will still fail the exams when they take it again.
I have installed different boilers over 3.5 years but now im going around doing servicing and looking for faults. I do open boilers to check all the content involved in the exercise...but would you strip a boiler that's working fine and after all the said checks when nothing is wrong with it?
I'm just looking for clarity. In the case of ratios i have done my honework now...I'm good. Thanks
