    More details, please?

    How was the added-on living space heated?



    Was the boiler upsized to accommodate the additional load? (Better yet, what is the total EDR of the connected radiation? Ditto for the boiler.)



    Is the downstairs 10° warmer than the upstairs or vice-versa?



    What parts are plumbed in copper?



    Got any pictures?

    steam eadache

    will check on those

    questions asap! upstairs is colder & room that used to be the garage is colder. boiler was there they just added radiators with no thought that the boiler may be to small my bigger concern is the 160 degree water coming from the side arm water heater which i dont think is ever a good idea to add to a steam system.

    If the boiler is constantly trying to make steam then it's always going to be hot. Odds are they have the aquastat wired to shut off the pump when the boiler water is too cool to heat the water, but not when the DHW in the indirect reaches 135° (or whatever it should be set to). No one would have noticed that there was a problem until they overloaded he boiler and then the weather got cold.



    Check the wiring against the IOM if you have it. If not, what make/model of indirect are we dealing with, and what boiler?
