I’m new to this, so be patient.  We are building in ski country and I want to build into a closet a ski boot drier using PVC pipe mounted on a wall with an air space behind it.  Any suggestions on a low heat, heater with a fan?  We have in floor radient heat, if that’s any help.  I figure that if the heat source is on the floor, it will rise and enter the tubes and the fan would help distribute  the warm air, thus drying the boots.
