Jun 14, 2018 · Steam boilers should never operate without main pipe insulation. The main steam lines should be insulated with a minimum of 1” pipe insulation. Main pipes that are not insulated cause higher fuel bills, more water in the system due to increased condensation in steam mains, slower heating, and possible system noise issues.

Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam. The air surrounding the pipes is also cooler than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.
Sep 01, 2012 · Thanks, Dave. I was under the impression that if the wet returns are above the boiler water line that they, too, become steam-carrying pipes. As it stands now, the wet returns are mostly above the existing boiler water line. They are pitched ever so slightly, as noted in my first post.
2. Steam or Hot Water System. Steam is a highly efficient heat transfer fluid. It has a low mass density and no temperature limitation. It is also fast and has great control possibilities. Even though steam is efficient, hot water systems/boilers are somewhat more efficient than steam boilers.

Dec 12, 2014 · Trapped Water. Water becoming trapped in your boiler is another common cause of loud banging noises.

When water boils into steam, it expands around to around 1700 times its volume.
If this happens, water can no longer drain from the radiator back into the boiler when it condenses. Instead, the water pools in the pipe and blocks the hot steam from reaching the radiator. A clear indicator that water is pooling in the pipes is an excessively loud banging sound coming from the radiator as it turns on.
If you didn’t see any water, shut off the boiler, let it cool down, and then add water.

Jun 18, 2014 · Most two-pipe steam systems are similar to two-pipe, direct-return hot water systems. The big difference is that, unlike a hot water system, the return line doesn't increase much in size as it returns to the boiler. With steam, the lines are picking up condensate, not the much greater flow of water you expect to see in a hot water system.
Modern boiler manufacturers use the piping around the boiler to dry out the steam. Undersized pipes create higher outlet velocities, which can carry water out of the boiler as wet steam. Follow the installation instructions for good performance. For best performance, move up a pipe size, or add a riser to slow steam velocity and distribute
copper steam lines I wouldn't use copper anywhere on the header or any other near boiler piping. Especially it it was soft soldered .
