I am installing a Leisure Line Pocono.
I am building a jacket to tie into the heating system via the cold air return. My design is based on this idea:
I have remove the "Lid" so the top of the burn box is very accessable.
This allows me to easily place a copper coil on top of the burn box. I plan to use 5/8 soft copper pipe to make the coil, and for the send and return from my existing 40 gallon hotwater tank.
The outlet in the existing tank will be the drain, the inlet will be at the pressure relief valve entry. The pressure relief valve is about 1 inch higher that the top of the stove where the coil will be placed.
I will try natural convection for the water transport, but will add a circulating pump if necessary.
Now, if the above doesn't make alarms go off in your head, my question is, how many feet of the copper tubing should be used for the loop.
