I just have a small 15,000 BTU natural gas un-powered "wall furnace",

swear by natural gas or propane radiant heat.

Is that a vented furnace? I've used torpedo and kerosene heaters but they
dump at least a gallon of water for gallon of fuel or near that into
atmosphere. Navy blimps burning diesel actually got heavier as fuel burned
out. Just a bit of trivia. The collected the water vapor from exhaust and
sent it to ballast tanks. Saved venting helium to adjust buoyancy.
