Unvented course

[markfxy]

everybody passes if you don't get 100% they sit you down and go through it with you until you pass, same as all these mickey mouse courses never known anyone to fail yet.

I totally agree with you mate

 

[chris watkins]

is that on the multi choice?
must have changed

Yes, sorry (note to self, check before you hit the B button)

I have my unvented a week Monday so will have my head in my unvented book every night next week. Not confident about it at all, don't want to go back to work on the Tuesday and look thick.

Ash don't worry about it you will fly through it it's not hard and it will come with experience
There is nothing to an unvented cylinder there a lot easier that a standard system

Good job you don't go to my local one cos they fail people, last one I went on a lad did not make it, he was not a happy bunny!!

Must be a lot better at it in N.I. cos at least 75% of ones I go to overhear are incorrectly installed, Gary !!!!
I just can't work it out, all they had to do is follow the M. Instructions but no they new better.

 

[Gray0689]

Well they must be stupid or just very lazy there is nothing to an unvented cylinder

To be fair he was a bit of a muppet, he just couldn't do the calculations, which is why I asked !

 

[jase158]

Passed with flying colours, as easy as pie.

Now I look back, dont know what I was worried about.

 

[hammers4spanner]

what was the actuall exam like?

I hate being tested !!

Told you it was lol

You do a written exam, all answers in book, u get 3 chances to get right answer, 100 percent pass rate. Then list the components, look in the book and copy. Work out D2 sizes. Then go and look at a cylinder full of faults, it is really really hard to fail

And know you know the 9metre rule jase lol

 

[chris watkins]

And know you know the 9metre rule jase lol

I still have no idea what so ever what the 9 M rule is ?? I have had a look at my 2 tapes one is 5M & the other is only small being just 3M even if I use em both I can't make 9 so what is it Gray ???

Discharge pipe (D2)
This pipework runs from the tundish to the termination point.
It is supplied by the installer and must be installed correctly for both safety and design considerations.
It must be terminated in a safe place where there is no risk to persons in the vicinity of the discharge.
It must be of metal and capable of withstanding the temperature of the discharged water.
It must be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9 metres long. If the total equivalent resistance length is in excess of 9 metres see sizing of D2 copper discharge pipe for common temperature relief valve out sizes on page 7.

My unvented was a mare. Full day course, paid upfront, no reading material but I had fitted a couple. Anyway turned up at 8.30, spent 45 mins on admin, went through a powerpoint presentation, seen the photos of one wall left in the house when it goes wrong, quick cup of tea, quick practical, 27 multiple choice questions at 11.30, back in the van and on the way home for 11.50. Didn't learn anything that wasn't already in the MI's. So slightly poorer, cost of course, diesel to get there and back, lost earnings and certification. But now(last 18 months) I can legally work on unvented cylinders. Really looking forward to my refresher in 3 1/2 years time to continue on this lucrative path.

 

[peteheat]

What book is everyone referring to?

I have done a good few with solar no problems so far, maybe because I respect the fact that they can be lethal.

I hear they are bringing our regulations in line with the UK next year so it's more courses for everyone here.

After such a poor experience at this training centre you of course will not be going back to them will you SimonG ? & will tell others just how poor the training was ?
Just like all other areas of life there are good & bad. Market forces should be brought to bear, you could alway complain if not to the centre themselves then to the awarding body it is not in their interest to have unsatisfied customers either.
As I have said before my local one fortunately is very good, 8.30 start 15min paperwork then power point till tea (9.45) bit after than out into the workshop looking at the different units & packages & other bits, then they had a rig that showed all the safety valves working including the Temperature relief going off, then lunch & back into the classroom going through the rest including the calculations etc. Exam started around 2'ish I think & we were out of there by 4PM.
Loss of a day's money + the cost but did learn loads, so not so bad.

I see Gray it is just the D2 pipe sizing, page 7 of what though ? & D2 over here does not now have to be a metal pipe but cant be certain types of plastic.

 

[Gray0689]

Didn't say it was anything different and I only said remember the 9 metre rule simple as that

I honestly don't see what there is to learn in that time there simple

 

[chris watkins]

OK, thanks Gray.

Change of material for D2, and now allowed to use hep2o self seal valve Dow allows connection to internal stack,I've done a few reassessment guys lately and they are moaning about having to redo the course but they don't know about the changes and have forgotten about sizing the D2 so they don't help the cause for saying reassessment isn't needed
