Thanks. I figured we should open at least a vent, didn't think of condensation though.I would open the roof vent a crack and also open a window, more to reduce condensation than other concerns. You'll loose a little heat that way but the buddy is radiant heat. We've only run the Buddy through the night once but don't have to deal with Minnesota temps.
Oh boy. I'm hoping we won't need it, we're getting our controller worked on, actually replaced, it kept burning out the batteries, went through ours, so bought a new one, happened again, bought another, same thing, so we were lucky they let us buy another, so now we know it's the controller, now we should be able to use the furnace.We have 2 Mr Buddy heaters. The biggest problem we have with them is keeping them on! The o2 sensor likes to shut them down.
