I'm by no means any sort of expert on boilers. That said, I'm familiar with how my home system operates, and am comfortable enough to do basic maintenance.
I'm trying to help out a friend of my mom's. He recently bought an older home next to hers, and called me tonight asking about his boiler. I walked through the place 2 weeks ago with him, just to look around. The boiler is a Weil McLain NG fired hot water unit, about the same age as mine (mine is a VHE direct vent, his is *I think* a CG series? With a natural draft. It's much narrower physically than mine. I'll verify all the model info next time I get over there, tomorrow or Thursday.
He had a plumber over to look at it, walk him thru basic knowledge stuff, and the plumber also replaced the Backflow Preventer and Pressure regulator/auto fill valve, bled the system, cleaned the boiler, etc, pronounced it all good. No issues with any of his work. It's a similar piping setup to mine, 2 main trunks with branches off to cast iron radiators.
His question to me was this: the water pressure is correct for a 2 story system, but he says the radiators don't get hot, like my house and my mom's house do (she has a WM 80% boiler and a 3 story house/system). His tridicator never tops 120 degrees F. And I noticed when I was there too that the thing *cycles on and off constantly*. As in pump starts, boiler fires, runs from 2 to 8 minutes, then shuts down. He took the panel off and said that what I think is the 'high limit' is set to 180. The pump is circulating.
Any ideas? I'd like to help him out, he's a long time family friend (and an attorney whose services I may need someday - haha).
Sorry for the long post, once I get going, ain't no stopping me.
Thanks,
Andy
