Another one bits the dust. (Stroman)

Another boiler fails prematurely. This was a copper tube boiler that was connected to a high mass cast iron radiator system with no boiler protection, no lined brick chimney, and way over sized. Lasted about 15 years and looked better inside than I expected. It "worked" fine except for the fact that it set off the CO detectors on the 2nd floor and would "whistle" from a leak in the header whenever the pressure hit about 60 lbs. due to a water logged expansions tank. Hmmm, relief valved never blew.

    Yikes!

    Thanks for the graphic illustration of why boilers that are not designed to deal with low return water temperatures need to be protected from them. Do you suppose that a buffer tank and a thermic valve could have made this system happier?

    We have been using the Taco I Control 2 Way Mixing valve. It is so simple to use and will protect the boiler and give outdoor reset if you want.

    I have had such good luck the the Trinity condensing boilers that I usually recommend them for the radiator jobs we do. That is what we replaced this one with. Photos when the job is complete.
