that's fairly expensive and useless, because of poor thermal contact
between the copper pipe and the flue gas and the extra heat exchanger.
better to cast a flat top for the stove with some concrete and wire,
with a flat soft copper coil in the middle. this can also make a nice
temp-controlled cooking surface.
