Your question Best, is easily answered the books you talk about are the Manufaturers Instructions & / or the training manuals that accompany the courses.
The fatal flaw in your plans for a non-assessment world is that plumbers & heating engineers will not read information given to them, it is the old throw the MI's on the ground as soon as the new boiler comes out of the box, walk all over it until it comes to turning on said boiler & then only picking them up & look at picture's when the thing don't work !!!!
And don't tell me you lot don't do that cos I see it day in day out.
I will say again if you have competed your Part G in half a day you have gone to the wrong training (& assessment) center. Again you want to complain about the quality & value but you don't want to spend any time or money completing them.
You do make me laugh, only in this industry.
I do largely agree with you Chris, but the MIs that you mention that come with unvented units, while good, are not obviously detailed enough usually for all circumstances - like for all discharge possibilities.
Nor are the MIs much good for a beginner, just qualified, as advisable pipework runs etc might be unclear.
As to the training manual, - last I saw it was in the training centre! Fat lot of good that is if I come across something on a job I am unsure meets regs or not! That is why I say, we need the regs in a book & in simple form to refer to, even if we pay extra for it.
You are right about what most of us would do if no training, - probably a brief read of MIs or regs at most. I try to read instructions that comes with anything, as you nearly always learn something, but must admit we all have left the instructions on the floor at times. Very good point! :smile:
Training is needed but IMO it should be only part of what is required & needs to actually teach things to us, - not just give out questions.
My G3 has been a half day & I learn mainly only what I read tbh.
It would help a lot if each job you do could at random perhaps be accessed by someone that actually knew the job and you risked loosing your card if you were repeatedly doing anything seriously wrong.
By that I mean, we all do a driving test in UK, but if we drive dangerously, we can & should loose the licence. I bet driving would be a lot worse on roads if there were no laws enforceable by the police. But we can have days of correct expert training at plumbing courses & then take our card & "throw" the work in carelessly anyhow. If there is nobody coming behind us to police our work, then rules will be broken by some.
That's my rant over! :smile:
