I see this rectangular plywood box in a crawlspace. Im wondering what is it. After looking into the ends I realize that this guy was inventive but DUMB!!
Its a baseboard heater in an enclosed plywood box. Oh and the wiring was top notch too…
Looks to me like an accident waiting to happen . Thanks for the picture .
I’m seeing more Warm Board used in new construction. Usually covered with hardwood tongue and groove.
