Hello r/DIY. Long time reader, first time poster.I've got a house built in 1927 that is heated by steam radiators. Interestingly, the original coal furnace (refitted for natural gas in the 30s) still heats the place through the old radiators. It's a wonderful heat system that's remarkably effective and efficient compared to other plaves I've lived.Over the last two years, however, 2 of the radiators have stopped "working". They don't get hot and thus the rooms get very cold. Is there a known issue that can cause the steam pipes on these old systems to clog up? Anything i can try to get them cooking again?I appreciate any insight! via /r/DIY https://ift.tt/2Qhi4sA
