I came across a video of a barrel stove with heat exchanger pipes over the flames. I was curious if it could be redesigned into a rocket heater keeping the pipes, yet given the rocket stove benefit of not using to much wood. And if so, what is the best design? I thought since the hottest part besides the firebox, would be the heat riser core. Maybe integrate the pipes within somehow.
I’ve got a shop that I plan to heat up using the heat exchanger pipe method, with a blower pushing air through the pipes. Trying to push the heat off the unit much better.
I was wondering what kind of pipe material would be sufficient to withstand the extreme temps?
