It would be a great investment! The heater is just gonna warm the air.With the heater running and humidity high.You are only creating condensation on the walls and ceiling.You need to have some type of exhaust as well.Put a theromstat on small fan.Set it at about 68 or 70.That will help draw some of the moisture out of the room and decrease the chances of fungus and the dreaded black mold! Hope all goes well!
