Hot tub room
I have a customer who enclosed his hot tub in a wooden frame room on the patio of his home. 16' by 19' room, 10' high at the peak, 7' sidewalls. Open stud walls, only source of heat is a portable 110 volt propane heater as needed. He does not plan to insulate, just wants to vent the moisture out of the room. When he opens the lid on the hot tub, moisture drips off the joists.
He does not plan to use any other source of heat in the room.
We can purchase a humidistat-controlled fan easily enough.
How do I properly size this fan?
Is it smarter to vent thru the peak or should I place it about 6.5' off the floor near the hot tub?
How do I provide makeup air or is leakage thru the studs & windows going to be sufficient?
