It's interesting that a heat pump can be cheaper than burning natural 
gas these days.

Two other alternatives: a) burn natural gas in a $200 unvented heater 
and use a dehumidifier or an $80 window AC with a humidistat indoors to 
condense water vapor, and b) cogenerate heat and electricity with a $900 
Honda EU2000 generator, which might have a natural gas conversion kit. 
An exhaust hookah can help remove and store heat, and the exhaust can 
depressurize a small enclosure to avoid indoor air pollution, and it 
looks like an EU2000 can be plugged into an active wall socket, 
illegally of course :-)

We might also consider non-recurring costs.
