New 40x60 garage

[Jeremyvk6]

Building a 40x60x14 garage this summer with infloor heat and fully finished and insulated. I put an exhaust fan on a humidistat in my attached 3 stall fully finished garage with infloor heat for moisture. Am I going to have the same issue with moisture in the shed? Any ideas to exhaust air on a bigger scale? Thanks

Keeping a handle on the Humidity and monitoring it as well as Trying to Control it is important. Air Flow helps a lot to control Humidity and eliminate stagnant air holding moisture. I control and manage mine here in Ohio all 4 seasons and it really helps a lot in every aspect considered. Each case and situation can vary slightly but the humidistat and thermometer's Don't lie!

I'm in Minnesota so yes we get the temp changes and things too. Any recommendations as to what to use? An air exchanger? Wall fan ? Something like that.

I'm also in MN, my shop is heated and cooled and very well insulated, I have never had any problems with condensation except a few times a year when the conditions are just right you can see some dark spots on the floor. I'm sure a dehumidifier would take care of that but it's never caused a real problem. I do sometimes wish I had an exhaust fan and I think that would also take care of the issue. If you do the exhaust fan you also need to have a vent somewhere to allow air in or leave a door or window open. Here is one I have considered.

I'm in MN with a 46x46x14 and in the right conditions maybe have some higher humidity. I have in-floor heat as well. I also have a 9ft ceiling fan in the middle of the ceiling which helps a great deal. My recommendation is to have floor drains for bulk water and just occasionally open a big garage door to let in some dry air if it gets that bad in the winter. My opinion it would be no different than constantly running an exhaust fan sucking heated air out.

I did and 135cfm bath fan in the ceiling of my shop with 6in insulated duct that vents out through a vent in the roof. Its controlled by a humidistat and I have a little 8in fresh air vent with a little servo operated door that opens when the fan turns on and closes when it turns off, its a pretty slick little system and I can turn it on manually also to clear fumes from the workshop too.
