New boiler or repair?

Well it has a good clean burn, the valve came from exactly the same model and I have a gas engineer coming in January to service and do a safety check.

Just thought I would come back as everything is fine with the boiler and the second hand gas valve.
I just wonder why people on here try to frighten responsible DIYers saying i should check "Whats the inlet pressure? The burner pressure? is it burning too much gas, not enough gas, what does the gas rate say? What is you analyser reading telling you? "

So please explain to me how changing the gas valve, which simply turns the gas on and off can affect these?
The gas jets are completely separate and untouched, so is the burner chamber and flue.

& the fact that you don't know the answers to these questions is the exact reason you shouldn't be touching the gas components

Darwinism (again)

Some older boilers will keep going if maintained, and are better made than new, cheaper brands. We kept an old Valliant boiler going that was almost 20 years old (we inherited it when we moved in). As others have said, may be worth buying another of any parts replaced if you see them cheap.



Recently had it replaced with a Worcester Bosch combi boiler, we got it interest free for 3 years through Eon Energy (think its about £65 a month)

They just built the interest into the price. No free lunch.

I assumed they did, but we had 4 quotes all between £2,500 and £3,300 so thought it middle of the range, plus interest free thrown in

Once again the registered gas installers try and frighten the life out of anyone who dares to touch their precious gas. Its a good way of preserving their cash cow.

The gas regs don't require you to be registered to work on gas in your own home only to be competent and don't for one minute think being registered makes anyone competent. It also doesn't absolve them from making a mistake and being liable for it.

I've employed two RGI, the first one left me with a serious leak, I couldn't get hold of him so called the gas board who capped the meter off, the second one put a cap end on a pipe in the airing cupboard at my mum and dads which fell off when touched with some towels and gas poured out so I had to frantically find the meter box key!

All that matters is that you do a good job and know your limitations. I personally know that I can't solder for toffee so I don't try on gas pipes, changing a few screwed on fittings or electrical bits on the other hand is fairly simple if you know what your doing.

Also bear in mind that with a balanced flue there are no products of combustion in the room (assuming its not leaking) and therefore the risks from an incorrect mixture are removed although it does need setting correctly for economy. I also always have a carbon monoxide alarm in any location where I have a gas appliance (and also where my wood burner is located).

As an aside I can also rebuild the brakes on my car (have done so on dozens of vehicles). This has a far higher risk of death to it and yet you don't see mechanics bleating on about not touching your car!

Just remember the Ronan Point disaster was caused by a professional gas installer and was the start of the CORGI registration scheme for those charging for gas work.
