I booked this course a couple of months ago, attended on 22/04/2015. I was so excited when I booked the course, I've been an installer for 8 years now and without sounding big headed am more than competent in that area, but for a long time I've felt that I need to be offering a more complete service, that's where fault finding comes in. so after a 3 hour journey and £150.00 or so, I was bitterly disappointed with what I received. Firstly id like to say that Steve (the trainer) quite clearly has some experience and a lot of knowledge when it comes to boiler repair and fault finding and I'm sure that he could probably repair pretty much anything that heats water, I really am not disputing this in any way and think that it's honourable to want to share this knowledge (even if the whole thing is one big cash generator for the man, you cant argue with good business). that's the Pro. here are the cons. He's rude! the man is not interested in anything the trainees wanted to say, he had a script (or so it seemed) which he has memorised very well, with the help of his slide show, and he did not want to stray away from that. I've taken many courses on gas boilers, unvented, domestic boiler appreciation and understanding etc... all of which had some things in common, they were quite relaxed, delivered by people who knew how to communicate, and were filled with the engineers, both trainers and trainees, discussing things that they/ we have come across on the job, as far as im concerned this does nothing but aid in the learning, personally im going to remember something a lot easier if I can relate it to something that has happened in my own career. I tried to ask him a question about something I had come across on the job, to which I received, "are you finished?"...Really? the man doesn't have time to answer a question, but spoke at length about how rich he is and how big his house is countless times, no "nobody cares how much money you have!" secondly I was told that that the course would be a day of working on boilers to find faults etc... Complete Lies! there are boilers to "work on", which ewe were given around half an hour to use throughout the whole day, and then told during our breaks that we were welcome to have a go on them. the problem is that none of the boilers are even piped in or working in any fashion. They are literally old boilers that have been hung on the wall and wired in. I was expecting "working boilers" with faults that we had to find. NO SUCH LUCK. he did however have boxes and boxes of sensors, switches etc... for us to test, the problem is, when I'm called to a job because they've got a fault boiler, I can't see that I'm going to be lucky enough to have the faulty part handed to me by the customer! im going to have to figure out which part I need to test , locate it and figure out how to test it and if need be how to replace it. What I did learn from this course is how to go through a box of various switches and sensors, and tell you which ones work and which ones don't, I'm yet to find a job which involves this skill! thirdly, he then went over to the only working boiler in the room, a Vaillant. I was pretty pleased that it was a Vaillant as I am a huge fan of the boilers and have been on a few courses at their centres of excellence so am pretty clued up when it comes to how they work. Steve, as it turns out, is not! he went on to explain to the group, some of whom were quite clearly new to this and needed correct guidance to begin their career in gas heating, that there MUST be at least 20mbar of gas pressure at the point just before the pipe enters the boiler(Vaillant EcoTec pro 24) and that you are allowed to lose 1mbar through the gas valve, so the pressure at the boiler test point must be atleast 19mbar...somebody needs to inform Vaillant of this fact as they seem to think, and have told me on many occasions, that a Vaillant EcoTec Pro 24 will work with 16mbar before the boiler, and that you will lose 3mbar through the gas valve, making the pressure at the test point 13mbar, this is assuming that all of the appropriate tests are carried out and pass. I think I'm going to go with Vaillant on that one. He then went on to tell us that there Must be a 22mm gas pipe all the way to any condensing boiler... Really. A Vaillant combi boiler has a 15mm inlet so again I think one of us really needs to give them a call to explain how dreadfully wrong they have been all this time. I've been installing for a while now and I know, and the MI's will tell you the same, that not all boilers require a 22mm gas pipe, some will but some will be fine with some 15mm pipe running to it, and there are tests which will confirm whether or not a gas pipe needs to be upgraded or not, as an installer this is something that I carry out on every single job, and there have been many times where 15mm has been more than enough for that specific boiler. I apologise for the essay and the rant, but I feel that this "course" is such a rip off and a complete waste of time, I came away from there which very little knowledge that I didn't have when I walked into the room that morning and genuinely wish I'd saved my money. Don't waste your time and hard earned money on this, I promise you, you could find better information on youtube! I will now be testing the components on the boilers that I am removing as well as those of my family and of boilers that I am installing to try to gain some experience and confidence in doing so, I should have been given this opportunity at the rip off centre that is Mr Combi.
