Should I replace my boiler

Best reply of the thread so far for me. Everyone's gas consumption will have increased this year and it's not your boiler's fault - it's the crazily cold, long Winter we've endured. .

Quite - I note

And


These two maps are of the year before last, and last.
Over most of england, the year before last, winter was significantly warmer than normal.
Over the average winter temperature of the last 20 years or so, it went from about 1C warmer, to about 1C colder.

The average heating needed is typically about 10C.
2C colder is bang on 20% extra heating needed.

so the consensus is stick with my existing boiler

I think most of the wasted energy of a gas boiler (ignoring a pilot light) goes out the flue.

I'm not sure if incomplete combustion of gas/CO going out the flue would be picked up on any inspection/service (unless it was perhaps really bad)

It should be if the service engineer uses a FGA on it.

I use an FGA on all servicing of boilers that I can access the flue on.

Check out the Glowworm Ultracom 2.

Check out the weather compensation feature, it's a key component to increasing your efficiency.

You must have a return flow filter, as the heat exchanger has a smaller bore compared to old boilers, giving them about 1% improvement in efficiency, but makes them more prone to clogging.

Sounds very expensive/unnecessarily complicated/prone to more expensive upkeep to me. But when it comes to new boilers i accept I'm a bit of a Luddite...

I broadly agree with not replacing a working boiler, with the caveat that if the boiler in question is very inefficient, then I would calculate the likely annual savings a modern boiler would deliver. If this figure is high enough, say over £300 per annum, then I would probably choose to get a new one.

£100-£300 a year savings, avg life of a modern boiler = 10 yrs, avg cost of a new boiler £2k, which is why most of us say unless it's really not cost effective to repair keep it going as long as possible

No..dont change it. My Gloworm boiler is around 34 years old so yours is just a youngster !
