Boiler repair or replace?

David_8 Member Posts: 2
In my 75 year old house in Michigan, I have a Weil-McLain boiler (for radiator steam heat), 250,000 BTU, that is about 15-20 years old. I have lived here 7 years and just learned that the boiler should be flushed every year. It now leaks, and the seals in one of the eight cells (right word?) need re-sealing. It still produces heat but does not hold a vacuum, so the burner is on way too long and I had to turn off the automatic water feed to avoid flooding the boiler. Repair is $2100 with no warranty. Replacing boiler is $6000 with warranty, installed, though I still will shop around for better prices. Has anyone had a repair like this done? I hate to spend $6K when I can spend $2K and get it working right, but if other seals go bad I will lose the value of my $2K repair. I understand that if I had it flushed every year I probably could have avoided this, but it's too late now, though if I had it repaired I would flush each year afterward. I would appreciate any thoughts from someone experienced with this. Thanks.

    at that age

    At that age, I'd replace it. The fuel savings could pay for the 6K over time. Get a heat loss done, you're probably oversized to boot. A smaller more efficient boiler could cut your fuel bill in 1/2, and well worth the investment
