It can be done, just not legally. If something where to god forbid go wrong, no insurance company would ever pay out worse yet you could be held accountable depending on the situations.

We should find the guy that hooked that up and ask him what he was thinking. Oh wait, it was me. :oops:

I have spoken about this at length in other threads, but the long and short of it is that there is nothing wrong with multiple appliances per flue, the issue is when one of them is a "solid fuel appliance". When you hook a wood burner into the same flue as an oil or gas unit, and there is a chimney fire, the fire can draw air through the other appliance and its draft control. Anthracite does not create creosote or cause chimney fires, and actually requires a draft control of its own...but the code does not distinguish between wood and anthracite. If it were two oil boilers, the concern would be the size of the piping and flue. This particular chimney handles both boilers firing without issue, but since the video was filmed 3 years ago I have changed the flue piping arrangement and controls so that only one boiler can be used at a time.

Rob's too fast for me.

AFAIK even in the code the issue is not the number of appliances connected to a chimney, but rather the sharing of a flue by appliances that burn different fuels. When we bought our house there were two big boilers that shared a flue by connecting to a single smoke pipe "trunk line". I was assured by a licensed master plumber that this set-up was safe and lawful, as long as both boilers run on the same fuel.

well those clearly don't run the same fuel (one is oil, one is coal)... Im not so sure that can be done in MA. (I'd have to ask a Code enforcement authority).
Either way, that looks like one sweet set up and we all know Rob is well attuned just about everything regarding heating his home and coal burning so I have no doubt it all functions wonderfully ;)

I never said it was code...it definitely is not. Don't bother asking anyone in MA, the chimney gestapo will arrive in minutes and take your stove.

If hooking two appliances to one chimney, wouldn't the inactive appliance feed the chimney draft and ruin the draft for the appliance that is in use? Or must you isolate the inactive appliance so that can't happen?

It depends. In this case the oil burner is a Riello unit with an air shutter that closes when not in use.

In our set-up each appliance has its own baro, so the draft at the appliance can be properly controlled.

What Lightning was pointing out is the loss of draft through the unused appliance.A baro can't compensate for that, only excess draft. Rob stated his oil burner automatically closes it's air intake so would not be effected.

With a decent chimney I doubt there would be excess loss.

We have a decent chimney, so there is plenty of draft for both appliances. If you have low draft conditions to start with, I can see how isolating the unused appliance might be needed.
