Micro CoGen.

  Very good deal indeed. I've got a set with that same head. Copper wound and trouble free for 4K hrs or so.

  I've got a 6/1 'roid  that lives on a anti-vibe mount in my basement. (yea, I know, a really bad idea for lots of reasons - perpetual bachelor-hood not the least of them - but it starts real easy when it's frigid outside and I'm getting lots of radiant heat from it too) Exhaust heat is extracted with a heat exchanger and routed to a motorcycle radiator with a fan, and the cooling system feeds a cast iron radiator upstairs. The house is passive solar heated and solar powered so the set-up is a nice addition on cloudy days when the batteries need charging.

Good to see and hear it running Geno.  Funny how these hot screaming deals always get a little more expensive in the long run, huh. Still, a diesel battery charger for around $500 ain't too shabby.   Bill
