I have two different steam systems in my home (formerly a duplex-each side had a system. I live in 3/4 and rent out 1/4).
we have lived in our original half for 14 years have a natural gas boiler (Currently 3 year old burnham) and quiet steam that fills all radiators quickly.
When we bought the other half we inherited an oil boiler (maybe ten years old now). The steam in this half seems very wet- it’s loud and spit-y.
some of the piping is buried in exterior walls- I don’t know if that cools it and makes it wet? In my original half all pipes are visible.
I replaced all the radiator valve within the last two years. Mostly varivalves and a few Danfoss thermostatic valves to help balance the oil system which I don’t believe was well balanced, but probably not helped by us dividing the house in half.
I’m in Concord, NH and having a hard time finding anyone who knows steam. Last year I had a new company service both boilers, but they wouldn’t discuss or touch my radiators. This year they no longer service oil burners and I worry I will need to use Irving for my service.
Any advice? NH contractors?
