Boiler Condemned :(

i agree with you though, mickie. i wouldn't touch a gas appliance when it came to installation or maintenance etc and wouldn't advise anyone but a gas safe engineer do so either

i havent got a chip, just dont like peoples attitudes towards working on gas and claiming its a monkeys job, kind of annoying to read from my side of the computer

Who said it's a monkey's job?? I don't think anyone said that, but going by your previous form in this thread, what people say and what you hear are 2 completely different things!

You seem to be under the impression that anyone not Gas Safe registered is a brainless idiot who will not give any thought to pressure drop and flow rate, correct fixings, following clearly documented flue location regs, correct methods of soldering copper, proper tools for the job etc etc etc.

I've done pretty much all the work on my extension/refurbishment, from drawing up all the plans to plumbing, electrics, roofing, insulating, ufh, hearths... and making sure that I read up on the relevant legislation and building regs pertinent to each part ensures that I am doing it safely and to a high standard. Honestly mate, you're not the only person capable of following instructions and doing a safe and quality job. Get off your high horse!

i guess all the info is readly available? going by what you're saying in regards to drop testing the gas meter, flow rates, pipe sizing, working and burner pressures, flue analysis..

you're pointing out you can do the job, anyone can read up on this stuff and do it them selfs.. which to me makes it sound like a monkey could pick it all up..

honestly, where are you getting all the info? are you telling me its all on the internet now? i think its time i quit and started working in b&q

With a modern boiler the risk of carbon monoxide poisoning is absolutely tiny, the fules are fanned unlike in th good old days of the blanced flue so everything should go outside the only risk is a massive leak on the boiler itself or the section of the flue inside the house.

If your so worried about your kids saftey even with your all singing all dancing Worcester boiler you should have a Carbon Monoxide detector installed which would cost about a 100th of your boiler replacement!

Citation needed.

ANY boiler can produce lethal amounts of CO without very much going wrong. Then all it takes is a broken seal or hole in a flue and you have a disaster on your hands. I agree it's not as bad as open flued (not balanced flue, totally different) appliances but the risk is still there. *ALL* condensing boilers produce a small amount of CO when burning (<200ppm, perfectly safe really), they don't burn perfectly clean like older boilers and if they aren't serviced the gas:air ratio can gradually slip and result in vastly more CO being produced. Half a turn with a screwdriver on the gas valve can be the difference between 100ppm CO and 10,000+ppm (parts per million).

Bit of an FYI on the OP's boiler (Powermax)... the gas pressure supplied to the burner is regulated by the air pressure (zero governor), if you get a hole in the flue or air intake the pressure changes dramatically compared to what it should be and can result in too much gas being used. What does that mean kids? Incomplete combustion and lots of Carbon Monoxide. So a hole in the flue on a Powermax is very serious indeed, even more so than usual. Unfortunately for the OP, the Powermax was produced by "Range" who were bought out by the Baxi Potterton group... who pretty swiftly ended full support & parts production for them when they realised what they'd taken on! Hence the need for a new boiler and not just a repair.
