Steam Draft

[BradWilson]

Morning all,

Two years ago we insulated the sugarhouse and covered the walls. We have an oil fired arch. Now, unless we open the door a few inches, we have little to no steam draft. We heat the sugarhouse with a wood stove but even when it's all warmed up, we still have lots of steam. Anyone else have this issue? What did you do to increase your draft? I hate keeping the door open, it makes my feet cold!

do you have a cupola or do you have a good with a steam stack? if you have a hood and stack, you can try adding another length or two to your steam stack? More stack should increase your draft?!

I have the same problem and i have a huge cupola with no steam hood i have to do the same thing leave my side door open a few inches which makes it cold my cupola is like 4X4 i have tried fans and the only thing that works is the door being open. So good luck trying to figure it out and i really dont want to get a hood

Evening,

Been out in the woods chasing leaks. We have a cupola and the opening is bigger than the evaporator. The evap is a 2x6 and the opening is directly above, approx 3.5'x7'. There are four door on the cupola approx 2'x2' each (friggin thing is big). That's why I can't believe that it won't draft. Thinking about putting in a "dog door" or something I can adjust to let some air in.

You need to replace all of the combustion air for the evaporator and your wood stove or you will create a negative pressure in the building. To get a good draft you need a supply of air to replace what is leaving.

I was just thinking the same thing. Creat an outside air intake using some ductwork. Draw in at floor level and dump it out in the rafters to a oid feeling the cold.

I usually boil with the front door open to the sugarhouse. Most of the time I like it that way. When it is cold or the wind isn't favorable for that, I close it most of the way or if all the way - then I have to play with my windows to get the right combination so the steam will get of the building. Sometimes it takes longer to get it right than other times.
