: if there is condensate trapped in the supply lines to the radiators, that will cause the banging sound until it is converted to steam.

: : I live in a 1947 vintage apartment building heated with steam radiators. The boiler operates on an hourly cycle, running for a period of time controlled by the outside temperature. Some radiators make banging noises (7 or 8 times) when steam starts coming in at the start of the heating cycle, then stay quiet for the remainder of the hour. We have changed the steam traps on the radiators and the condensate return lines with no positive results. We have also insulated the pipes leading to the radiators, except where they are in the wall space. Is there a remedy for this problem?


Banging in the pipes is usually a cause of excessive water in the steam lines.
Be sure that the water level in the boiler is not too high. Boilers with Automatic feeders should be flushed once a week. Also, all radiators should be pitched back to the steam supply if it's a one pipe system.
