The burners on my gas fired steam boiler were cycling on/off. I took the pigtail apart. Cleaned out the sludge and drained the tank. It seemed to fix the issue. It then happened again a few weeks later. Is there any additive you would recommend that might prevent or reduce the gunk buildup in an older boiler? Or do I simply need to drain it more frequently?

Heavy build up is an indication that you may be taking on excessive amount of replacement water.  If you are aware of any steam leaking from the system, you need to have that addressed.  Also if you have any buried, or hidden pipes they are suspect for leakage until inspection reveals otherwise.  There are boiler water treatment chemicals available through local sellers of heating boilers and repair parts.

Questions related to "Wet Heat". This is heating your home, office etc. with radiators, panels, and convector apparatus. Steam and water heat. I can answer questions about boilers, piping,and associated parts of these systems. Please do not ask for specific information about how I feel about one boiler, etc. over another--These questions should be directed to a licensed contractor that you know of, or that your neighbors and colleagues look to to provide solutions.
