Old wood boiler questions
New guy, non HVAC contractor. I have a wood boiler (oil boiler is primary) that I've never used and would like to. It's probably from the 50's, house was built in 55. Anyone know where I can likely find answers to some questions I have about this duel (oil/wood) system? I had a long time boiler guy come out last year to clean/inspect the oil boiler and he didn't know much about (old) wood boilers. And there's not much online apparently. Any input would be greatly appreciated.
