Of course, if you could get small 24*7 generators, doing the CHP
thing and putting the exhaust heat into the house, and the low-grade
residum into the heat source, plus using the shaft power to run a
compressor, then that would pretty much beat anything.

Either that or one of these micro CHP sterling engine boilers. If they
are 20% efficient at generating electricity and drives a 600%
efficient heat pump then you'd get 200% efficiency overall (80% +
120%). Should cut gas bills in half which isn't too bad.

cheers,
