Heating unvented crawlspace/no insulation
I have a crawlspace that is 18'x25' by 2-3' high. Very low. I plan to have "Cleanspace" encapsulation system installed on the dirt floor and up the walls next week. Foundation is lose stone with a concrete block cap, sill on the blocks. I have recently closed the one vent in the foundation and have been spraying foam insualtion (Great Stuff) between the lose rocks and cracks.
Would it be beneficial to hang a baseboard type radiator (ie slantfin)in the crawlspace if I do not put XPS insulation on the ground under the Vapor Barrier or along the walls? Would I just be wasting money?
