Webster Groves & Kirkwood steam heat questions
Is it worth keeping radiator heat in an older Webster Groves or Kirkwood house?
Many owners keep it because the radiators and piping are already there and the heat is quiet and even when the system is set up well. The cost of keeping it depends mostly on the boiler's condition. Get options from someone who works on steam and hot water before deciding.
Our boiler runs constantly but the house never gets warm. Why?
Common causes are failed main vents, a boiler sized wrong for the radiators, dirty boiler water, a pressure control set incorrectly, or on hot water systems air in the lines or a failing circulator. It's worth a diagnosis before replacing anything.
General steam heat questions
Why do my steam radiators bang?
Loud banging (water hammer) almost always means water is trapped where steam is trying to pass, usually in a pipe or radiator that has lost its pitch, or because the boiler water is surging. Steam condenses back to water and has to drain back to the boiler. If a radiator tilts the wrong way, a pipe has sagged, a one-pipe radiator valve is half closed, or the boiler water level is too high, the water pools and the next rush of steam slams into it. Common fixes are re-pitching radiators (a shim under the legs), re-pitching or re-hanging sagging pipe, opening one-pipe valves fully, correcting the water level, and skimming or cleaning dirty boiler water. Light ticking as metal warms up is normal; loud bangs are not.
Why are some of my radiators cold while others get hot?
Most uneven steam heat comes from air that can't get out: a stuck or undersized radiator air vent, missing or failed main vents in the basement, or on two-pipe systems a failed steam trap. Steam can only fill a radiator as fast as the air inside it escapes. Radiators far from the boiler need the air pushed out of the main pipes first, which is the job of the main vents near the end of each steam main. Other causes are a closed valve, a radiator tilted so water sits in it, or the pressure set too high, which makes vents close early. On a two-pipe system, one failed trap can let steam into the return and leave other radiators cold.
Should I repair or replace my old steam boiler?
Repair it if the boiler itself is sound and the trouble is controls, vents, water level or piping; consider replacement if the cast-iron sections are cracked or leaking, repairs keep piling up, or parts are no longer available. Age alone isn't the deciding factor: many old cast-iron steam boilers keep running for decades with basic care. Signs that point toward replacement are water leaking from the boiler sections, a firebox or heat exchanger that is rusted through, unsafe combustion or venting, and repeated major repairs. A new boiler has to be sized to the radiators you have, not to the old boiler, and piped correctly, or it can run worse than the one it replaced.
