If you use water, you could make the bench really short and still extract all the heat and then do a simple vent up the chimney.
However, the biggest problem will be finding a way to keep the water under 200F so as to not turn the water to steam, and cause a BOOM, due to high pressure.
How do we keep the temp under 200F, we could do a open container "bench".
We could do alot of short burns.
We could pump/dump/replace the bench water outside if it get to a "critial" temp of 180F.
We could look for other material other than water. that will turn to gas at a much higher temp like wax.
(or MERCURY, ok I am just kidding please dont try this)
Iterations are fine, we don't have to be perfect
