steam radiator

peter petruzzi_2

I have one radiator on the second floor that spits a lot of water out of one radiator. One pipe system, pressure set at about 1 lb. or less. Mains are pitched away from boiler. returns are tied in below water line. Header is 14 in. from water line to bottom of header. Weil Mclane boiler, 1 year old. Scimed boiler many times, added squick, Flush out boiler base and hartford loop regularly. One radiator in kitchen sonds like a pot boiling on a stove. It does not spit water from the vent. System was put in in 1927.Boiler was sized properly. Is header that critical? Worked on high pressure steam,did plumbing,and hot water. these old steam systems are a different Animal!! Thank You

14 inches?

Yike. Weil-McClain generally specifies 24 inches minimum to the header (check your boiler installation manual). And that assumes that all the oulets are used...

14 inches could produce some serious wet steam problems.

It really is important to regard the manufacturer's piping as minimum requirements to be met.

pot boiling on a stove

even though your pressuretrol is set to 1 psi, it sounds like you have more pressure than that. you need:

1.a good low pressure gauge [0-15 oz. gaugestore.com]

2.maybe a vaporstat [the standard pressuretrols are VERY inaccurate], and your system will work best under 12 oz.]

3.the downloaded installation manual for your boiler.

4. a copy of "the lost art of steam heating"

how is your venting?--nbc
