Thanks for that Simon, gives me a few reasons to say back to him when he says it's not a problem and 'there's plenty of leeway built into those figures'.

Hi Simon, Thanks for the reply. I rightly agree with you that only a competent person should install the a boiler and I don't claim to be one hence my reason for employing a CORGI engineer to do it. It's a shame that it's me having to double check his work as I don't think it's up to...

Hi All, Can someone tell me what the likely problems would be if a flue is longer than the manufacturers maximum stated length other than a voided warranty? The boiler in question is a Worcester Bosch 35CDI. I'm guessing that it may not be able to get enough air to or from the boiler...

A few lessons certainly have been learnt. The builder did everything except the gas and electrics which we organised. I think I will do as suggested and tell the guy to fit the correct boiler as requested. If he says no would CORGI be likely to act if it can be shown he's fitting the wrong...

That's basically what he is saying There was no written quote. I believe if a place qualifies for an exemption then you can install still install a condensing boiler

I believe so but nothing would surprise me now So is the basic consensus tell him to change the boiler to what I asked for in the first place. This will obviously annoy him so is it worth telling him to remove the boiler and get someone else to supply and fit?

He says that the original he supplied was a 25CDi and was a condensing boiler but I seem to remember (although I'm not 100%) it looking very similar to the 35CDi II RSF and I believe the greenstar models look different. He says he supplied a 35CDi II RSF because that's what I asked for. I...

Hi Arfurrr, Are you ready for a long story, sorry to bore you all :) It's become a whole messy affair. There is no original written quote just a verbal one (and yes I'm now starting to understand this is a mistake) to install a heating system into our 3.5 bedroom 2 bathroom house. The...

Thanks for the replies guys, they're very helpful and it's interesting to hear everyones opinions on these kind of things. A copper pipe from the prv to the outside world is what I understood it should be from comments here and elsewhere but I've just had a conversation with a technical guy...

Well spotted that man. This is another bone of contention as I asked for a Worcester Bosch 35CDi and they've installed a 35CDi II RSF which I didn't realise until yesterday isn't a condensing boiler. From what I've seen and what the guy has said I believe it does qualify for an exemption...

Thanks for that, so I take it what's shown in the image at the bottom of this mail is not allowed then as the prv pipe goes into a plastic waste pipe which then joins with the washing machine and then goes under a concrete floor and outside. Also if a Corgi fitter says something like this is...

Thanks for that, I thought it may be a la test like a cars mpg where the government figures are nothing like the actual ones you get.

Hi All, Does anyone know how close to the claimed efficiency rating boilers get and do non condensing get closer to the figure than condensing ones more of the time? In particular I'm referring to the Worcester Bosch 35CDi (condensing and 90% efficient) and the 35CDi II RSF (non condensing...

Hi All, Currently having a new Worcester Bosch 35CDi boiler fitted by a Corgi guy and for the pipe from the Pressure relief valve he plans to use a copper tube for the first 0.6 m and then drop it into a plastic waste pipe that'll go into and then across the concrete floor and finally be...

Thanks for the replies guys. You are basically backing up what I'm hearing from other people. I think I'll look into other alternatives a bit more. Any other opinions gratefully received. Cheers Stu

Hi All, I'm sorry for posting a question which you must all hear all the time but I could do with some advice. Myself and my girlfriend live in a 1920's 3 bed house which currently has one bathroom with a bath and a shower. The heating and hot water is currently supplied by a working but...
