Do I need a new boiler?

I have a 20 yr old weil mclean boiler. The firebox is coorroded and it need replacing for $400.00. The seals are "looking worn"
The service tech informed me that after 20 yrears it s not good to repair them just replace it for $7500.

The boiler operates at 85% effeciency.

Do you think I should repair it or replace it. And,should I trust the service guy who probably gets a commission if he seels me a boiler?

20 Year Old Boiler

A good boiler, well maintained should last 40 years or more.
I don't know what "seals" he's talking about but the only seals I know of can't be seen without taking the sections of the boiler apart. I think you got yourself a salesman in service man's clothing.

That being said, your boiler is likely WAY oversized. By installing a properly sized, more efficient boiler you could save a good bit on your fuel bill.

What makes you think it is oversized? You dont even know my house.

I dont know what seals he is talking about either. He sees them when cleaning the boiler.

BTW--I have 3800 sq ft house with 4 zones FHW

Oversized

What makes me think your boiler is oversized? Simply the fact than probably 90+% of them are.

Is this an oil or gas fired boiler? A model number might help me find out more about these "seals".

Seals

The only seal which would be visible during a cleaning would be the gas seal between the sections. Unless it is showing some signs of leakage as indicated by soot streaks on the insulation on the inside of the boiler jacket, I wouldn't worry about it. This sealant, as I recall, is a kaowool rope material.
It's not shown, but listed in the parts breakdown here:

Thank you for your time and answers

I am opting for the new combustion chamber.
