boiler question

Hello all

I recently purchased a home with radiant heat, last winter the boiler gave me no trouble. I lit the pilot on it today and noticed that there was condensation on one side that beaded up and lasted for about 10 min then went away. I had a company come out to take a look and they shut it down and said i needed to buy a new boiler beacuse it has a "water leak". I spoke to a few other companies over the phone and they explained the condensation is normal and the company that came out just wanted the "sale"

I fired it back up and have been running it all day and its dry as a bone until the boiler fires up then the condensation will last ten min then dry out,can it just be the temperature change causing the condensation or do you really think its leaking?

How do I add photos to a post?

Thanks for any input!

Ive tried to add a photo every way possible and cant seem to get it, but the condensation is building on the what seem to be cast iron sections that live behind the side cover...the boiler is a slant fin 100 series gas boiler

To post pics you need to use a host, like photobucket or others, then let us have the link.

I have a feeling that company A is just trying to drum up business. There is more money to be made selling a new unit.

Run it and if you experience problems look for answers then. BTW, how old is the boiler?

Life expectancy is about 20-25 years, depending on other conditions. Run it until it gives you additional problems, then replace it. Start putting money aside in a special fund for a future replacement. Also have the unit inspected by another company.

Re: boiler question

Congratulations, your old boiler is briefly acting like a new, high efficiency boiler!

You've just demonstrated how a condensing boiler works, and that the heating guy who told you your boiler needed replacement shouldn't be allowed anywhere near any mechanical equipment, especially your heating system.

When fuel (gas or oil) burns it mostly produces carbon dioxide and water - a fair amount of water - in the form of steam. A condensing boiler works by using a heat exchanger in the exhuast flue to "condense" the steam into water. which heats the water in the heat exchanger (saving you some money by lowering fuel bills).

When it's first starting up, the water in your boiler is cool enough to do the same thing, that's where the water comes from.

Re: boiler question

I agree it is normal, just condensation. i would like to know what type of boiler you have, you should have a plate with all the information somewhere on it.
