Did the boiler diagnostics today and picked up on all the faults pretty quickly using what I had been taught. Has given me so much more confidence that i'm really excited about putting it all in to practise (geek) Excellent day today, plenty of hands on and was good to see what we have been taught actually works. On top of that what made it better was the lads on the course were all really keen to be there too and wanted to learn and they were all just as impressed with the course as I was. I hate it on courses when there's usually 1 or 2 blokes who act like they know it all and constantly gobbing off. Wasn't like that this time, best course I have ever done and I have learnt more about how boilers work in the last 3 days than I have in the last 12 months, just goes to show if you are taught well things can be understood. Things seem a lot clearer to me now and I wont be so worried about working on boilers now. Still have loads to learn but this has been a great step up. Roll on 23rd December for system wiring and controls.
