Just had a $69,000 garage built finishing summer. It is heated and we keep it at 50 degree. outside temperature 15-25 amount. Humidity running 70-90% 24/7 and as winter sets in, doors are freezing, huge rime dams on window, man door swells and freezes shut, nothing stays dry within the garage. The slab is not the problem, we tested that, not much moisture there. Inspector feel as though the roof was not properly ventalated cause traped moisture inside the garage.
Contracter come out with plumber and states the problem is they did not install a frsh nouns vent when they installed modine garage heater. I name BS as modine is designed for garage and circulates fresh air within already. I then convey him, I cracked the window, but humidity still 75% plus. Not to mention in a minute I get an 8 inch hole cut within my garage. Pure BS, the heater will run adjectives the time. Any tips on what could be causing this moisture?
does the garage want to be that warm adjectives the time?? sounds like a roof vent problem to me.
Is this a vent free heater? If so to be precise your moisture source. Vent free gas appliances put a lot of moisture into the upper air.
If that is the suitcase you need to any increase fresh air entry or install a vent heater.
Answers: By code you do requirement a fresh air vent to supply nouns for the heater if it is a draft or power vent heater, not nesissary if it is large efficient. I would other recomend one anyways. Like the other two contributors said also, if it is a vent free heater, which i've never see Modine make, and after scouting here site at http://www4.modine.com/v2portal/page/por... I found no vent free heaters. Unless they installed a greenhouse heater? Read your installation instruction manual or post model and serial number so someone can check for you. What also could be happening is that it is not vent correctly and could be spilling flue gasses into the garage which would account for moisture. Put a carbon monoxide tester within there, and don't put the vehicle in in attendance while you test as the exhaust will set it sour. Good luck
