Can steam cause water hammer?
A common example of water hammer occurs during the start- up or energizing of a steam system. If the steam line is energized too quickly with out proper warm up time and the condensate created during the startup is not being properly removed; water hammer will be the result.
What causes water hammer in steam heating system?
Water Hammer caused by the sudden condensation of steam When steam loses its heat, it turns into condensate, whose specific volume is more than 1000 times smaller than that of steam. So when steam comes into contact with colder condensate and condenses, its volume is instantly reduced to next to nothing.
Why are my steam radiators banging?
When radiators in a hot-water system develop banging or hammering noises the problem is most often due to trapped air that cannot get out. Air gets into the system from the fresh water that is periodically added to the system (usually automatically) to replace water that evaporates or leaks out.

Knocking radiator sounds are generally a sign of trapped water or air in the system. When either gets stuck, steam is prevented from moving through the pipe into the radiator. This pressure build up can make a loud knocking or banging noise.
