What's up guys? After a ton of research on this site over the last year, I recently picked up a New Yorker boiler (planning on burning mostly coal) I read in a recent post on the topic of heat storage, Eric noted that adding even a small amount of extra water to a traditional boiler can have some benefits evening out the burning cycle, and acting as a sort of buffer. My new boiler holds just over 20 gallons, and I've thought of adding a water heater tank and circulator, upping the total amount of water in my set-up, maybe to 60 gallons or so. Just wondered what everyone thought, or if anyne had any advice on this. Thanks in advance.
