Passive Solar Air-Heating Panel 48"W x 72"H x 6"D
The parts for this panel were produced during validation of CNC part program software and were machined from clear pine rather than the normal hardwood.
Rather than toss the parts, this time I've glued 'em up and am offering the panel for sale at a reduced price.
Needs to go in a south-facing wall. A four-foot panel won't heat most workshops but this one will definitely help to warm it on cold winter days. Does not increase humidity, create a hot spot, make noise, or require electricity.
