Thinking of changing my conventional boiler to a condensing boiler

Andyleung

I’m thinking of changing my Potterten Netaheat Profile 40e conventional boiler to a condensing one.
I’ve done some research which says my model is F rated around 71% efficient and the new condensing ones can be 91% efficient, thereby saving 20% per year.
To give you an idea the bills are around £600-£700 per year for a 3 bed terraced house, but as were expecting a baby in the new year the other half will be at home for most of the time, I can see the gas bill shooting up to maybe £1k together with gas price rises.
If so would it make more sense to change it or wait until it breaks again before changing?

P.S the boiler only broke down once in the last 5 years (faulty fan) and at a guess its around 10 years old.

Thanks for your help

tough one, it all depends when it breaks - you won't know

If it breaks in the winter with the baby, could be a problem.
If you replace it now, is it money wasted before the baby arrives?
It has to be a personal choice I think.

Ive just had my conventional boiler replaced with a condensing boiler (pump went on the old one and it was noisy). It cost just over £2000 to have it installed.
I think sooner rather than later as you will get more value from it (and you can go round feeling environtmentally self-riteous lol).

Not sure how current the typical annual costs are but they seem way below yours!

I think i will leave it until it breaks as it does not look like i will save that much money within the next 5 years.
However to improve efficiency i will flush out the central heating system.
I think its a DIY jobby as it is probably a open system.

Thanks for all your advise

I find it a good idea to hover out our boiler once a year and brush any rust from the burners also regularly checking the pressure of the radiator system.

Our Vaillant boiler is around twenty years old and still going strong !
