RE: Landlord Fitted Boiler, Not Corgi Registered. [IMAGES ENCLOSED]

Pic 1 Done by an IDIOT

Pic 2 Pipes not level, corrosive flux (the green stuff) not cleaned off pipework, poor !

Pic 3 Wall scorched, pipes not clipped, little bits of pipe joined with straight couplings ! v poor

Pic 4 Looks OK to me, but I've been on the booze allday:eek: Amazing what you can do with a SLING.

Pic 5 Maybe he should just use end feed If he dosen't trust yorkies, maybe a pipe bender for his xmas.

It's extremely difficult to see from your pictures exactly what he has done and what he hasn't. It is obvious to all that it is a poor job though.

For what it is worth, this is what I make of it though.

The wiring tied up above the boiler. The LL has converted the place from system boiler configuration to combi boiler. The wiring is almost certainly the old stuff that originated from the airing cupboard and is now redundant. It should all be dead now.

Picture 5 - the bottom of the boiler. The copper pipe going through the wall is the PRV (pressure relief discharge) pipe and is designed to relieve the pressure in the system should it become too high. The pipe must be in copper and must be turned into the wall on the outside to prevent possible scalding. This is not the condensate connection that you mentioned earlier, in fact I cannot see a condensate pipe although the boiler is certainly a high efficiency condensing boiler - you can tell this from the flue picture.

The 3cm to 2cm reducing pipework you mentioned. This is actually 22mm and 15mm. Again it is hard to see what is what, but I would suspect that this is for the domestic hot and cold water supplies. If this is the case then it is not an issue as all combis have 15mm hot and cold connections and always have to join up to existing 22mm (and sometimes 28mm) pipe work. The two silver isolating valves fitted actually restrict the flow to 10mm.

The flue appears to have been measured and cut to size correctly. This is very unusual for a non-registered installer and you have no idea of the amount of incorrectly cut flues I see. The making good is indeed poor, I doubt very much whether it constitutes a danger though.

It looks to me as if the gas supply originates from above the boiler and is run entirely in 15mm copper. This is incorrect but only a gas rate test will confirm whether the boiler is under-gassed. Corgi will be able to check this if they attend. This doesn't automatically make the appliance dangerous though - much more information is needed.

I would assume that the boiler is powered from the 3-pin plug visible in the photo. It also needs a room thermostat to comply with building regulations. If the boiler does not have an onboard clock, then this should be a programmable room thermostat. It is not possible to see if this is the case from your photos.

If you are in a hard water area then the secondary heat exchanger requires protection from the minerals in the water depositing themselves on the HE and clogging it up - can't see that one has been fitted - but as you do not state your location this may be a moot point.

So, all in all a pretty rubbish job. But, bear in mind the fact that converting a system to accept a combi is quite an involved job that requires a thorough understanding of both system types. It would take a professional 3-4 man days to do properly. This would include power flushing and correctly decommissioning and removing all of the old, redundant bits and pieces.

I seriously doubt whether the new boiler will perform adequately and if the system has not been cleansed and protected properly I would measure its lifespan in weeks and not years. I would tend to doubt whether it is actually dangerous though.

NG did say that the gas was coming through a smaller pipe than it should be.

But the problem is it was fitted by an unregistered corgi installer and the job is overall poor. My concern is this slack work could be or could cause a problem in the future. And he ignored me when i told him he needs to be registered.

Undersized pipe work. There are two tests to perform, the first measures the working pressure of the gas supply with the appliance running. The second measures the actual consumption of gas and compares this to the stated heat input figure for the capacity of the boiler. Neither, I suspect, have been done and so it is not possible to say whether the gas supply is undersized as far too much information is missing.

According to eco-friendly, you do not need to be Corgi registered to do this work. He has 35 years experience of installing gas appliances illegally, so he is probably the best person to advise you in this matter. for further information about the legalities of this sort of thing please read this post http://forums.moneysavingexpert.com/....html?t=500867

you dont need to be corgi registered to install for yourself, i believe the phrasing is "not for reward or gain" meaning i can fit my own boiler to my own home or even my mums providing it is not for gain, i think that there may be a phrase in there about being a "competant person"also, your landlord doesnt live in the premisis he is working on, its not his private home its a profit making business, this may affect the law, please please please telephone corgi if your in any doubt as to the soundness of the installation and legallity of the work carried out, i spent a long time taking gas quals and am only too aware of how dangerous a bad install can be

Oh quickly one more thing National Grid placed a tester in the main gas box the tester had 2 tubes like a thermomiter but the tubes had water in them, he tester it with the boiler running and without it running and said there was a drop pressure. He also said the main gas pipe running to the boiler wasn't thick enough.

Corgi are coming out today to inspect the job.

I am no gas expert but I would say the device they used is a manometer. The gas board would have used it to check for gas leaks.
If it showed a pressure drop when running the boiler then surely this would have been a problem somewhere BEFORE the manometer not after!!! i.e. gas supply at meter where measured not providing enough pressure or maybe boiler using too much gas??? but I could be wrong maybe someone here will tell you more!
