Garden Shed in Summer, Sugar Shack in Winter?

[ArnoldGilson]

A steam hood will be effective enough in a sugar hut to remove steam and prevent moisture buildup. In any case, with it, you will have much less moisture in the room than without it. In a sugar bowl, it is better to install a steam hood as low as possible above the evaporator in which the juice is boiled. And if the cap is also equipped with a powerful fan, then dryness and the absence of mold in your shed are guaranteed to you.

Picking up where I left off.

So this is happening. I'm converting the garden shed to a sugar shack.
Once the new Evap arrives I should be able to figure out a stack fairly easily.

I am still thinking about power venting the steam hood out through the gable or sidewall of the shed through I'm guessing 8" or 12" vent pipe. While I understand this fan will see a lot of moisture, what have people used with success?
I've use squirrel cage inline fans in other applications with good success. I'm guessing this fan will need to be fairly powerful the ensure the maximum amount of steam leaves through the hood.

I will also add a fan on the gable vents to keep any steam that escapes the hood vented out.

Any suggestions of experiences to share?

Congratulations! Not a day goes by when I don't appreciate being inside for boils or any other sugaring work. The way you describe the the shack sounds fantastic.

Now, I have to give you some straight advice. Listen to the input you've already gotten from others. You will regret all the planning, work, resources, and power you are going to put into power venting the steam out. I strongly recommend you punch a second hole in your roof and let convection do all your work for you. Adding a steam hood and roof jack is about the simplest and most effective solution for your steam. The second best option is building a cupola - way more work, but also effective.

Very good advice. Thanks.

My personal issue is a loft that does not let me go straight up.
I may be able to use a couple 45's to clear the floor of the loft and then straight up. I'll have to see once I have the evaporator and look at formally mocking up the pipe.

On that note, what is a good pipe for the steam hood, and what is a good pipe for the smoke stack? Single or double wall, stainless, black? Pros/Cons other than price? Source?

Thanks,

Bryan

The steam pipe can be single wall pipe, but if you are dealing with a wood building double wall pipe at least for the chimney and follow all local laws for installation. It is better to go straight up thru the roof for the chimney as you will get a better draft. You will need to be at least above the roof by x the length of the evaporator.

Picked up the evaporator this weekend. I hope to have it in the shed the week after next, after traveling for work.

Steam hoods will vent straight up through the roof.

The chimney will go out the sidewall and up with double walled pipe. The arch is forced draft so I’m thinking it will adequate. I’ll review all fire tolerances and distances to combustibles as I don’t want to burn down the shed.

Very excited to get this started.

Any thoughts on putting the evaporator on a 4x8 of cement board as the floor is wood?

I have mine on a wood floor. The bottom of the evaporator doesn't get very hot but I still have cement board under it. The most important place for the cement board is in front for embers coming out of the fire box when loading wood. I turn the blower off for 10-15 seconds before opening the door to let the fire calm down a bit first.

I built a 10x14 shed (concrete floor), and when I started sugaring (3-4 gallons/year), I cut a hole in the roof for a triple-wall stove pipe. In the off season, I remove the pipe and nail a few shingles over the hole (no illegal sugarhouse here!) I also cut little flaps at the highest point of each gable end and hold those open with a long stick. I also cut a hole in one wall with a piece of plexiglass I can slide open. My evaporator is basically red brick, cinderblocks, some high-temp insulation, a couple pieces of steel plate, etc.
