not trying to be a smart butt (a$$), but my bet is the little units are priced very dear indeed.

much like using nife cells and their insane price for what they give you, i can think of at least one way of getting a much higher return in kwe plus heat using currently supplied nat/gas, and do so with a much higher efficiency.

Sounds better than methanol fuel cells, but at that power level you would need well designed venting. Even a small amount of carbon monoxide would be deadly in a home.

http://www.powerstream.com/methanol-fuel-cell.htm  Powerstream sells 25 watt-hour methanol fuel cells for the low low price of only $5,000.
