THE WOOD STOVE BOX

We began working on the concrete wood stove box last month. We built the formwork out of 3/4" plywood, welded wire mesh and reinforcing ties made from threaded rods. Within this box we ran 3/8" pex tubes that connect to the backup heating loop in the concrete floor. This loop is separate from the primary heating loop driven by the solar hot water panels. It will serve as a back up heating source at night or on cloudy days.
When complete, this will be a 3 1/2" thick, 3 sided concrete box that will transfer heat from the wood stove into the circulating water and down to the concrete floor. We hope to pour the box in the next few weeks. More details on this to follow....
