Boilers manufacturers say boilers last upto ten years but saying that if it is a good make ie Vaillant then it could last longer I have Vaillants on my service round that are over 15 years old. The only problem with old boilers is the efficiency will not be as good as with a new condensing boiler so I would bite the bullet and change the boiler make sure you use a heating engineer with a power flush machine and get a powerflush and a magnaclean magnetic filter fitted to the return of the boiler hope this helps cheers Ray
