And block up the water heater's combustion air openings and the draft hood
and enclose the generator and water heater in a plastic film room in
the basement depressurized by the generator combustion air supply,
with the water heater flue pipe running outdoors?
And a CO detector.

During the 5 days of terror last year after Charley, hot water was the last
thing on my mind.
In fact, at one point I was ready to murder everybody in order to get some
jeezis it was miserable.
We set (4) 5 gallon buckets of water in the backyard and by 5pm we were
taking makeshift showers, well, in the shower.

I've seen it done with a smaller engine- just a simple heat exchanger with a
larger water pipe welded around about 2 feet of exhaust pipe and plumbed in
to a water tank to form a thermic syphon- after about 3 or 4 hours you have
a tank full of hot water. Simple technology that worked like a charm, and
worked for years with no maintenance.

How about modifying a smallish gas heater, by piping the exhaust through the
I would use a separate heater for this purpose, permanaently removing the
burner, welding a new bell around the bottom of the heater.
Then put the whole thing outdoors for safety, as the others have noted.

Yup, can do. I know a guy who is doing it right now, works excellent for
him. He's running a lyster diesel and he pipes the exhaust into the **top**
of a 40/50 gal gas water heater and vents off the bottom (no burner in it
of course) He has so much hot water that sometimes he needs to drain some
off to cool it down if his demand is not high enough. I think his lyster
is about 6hp or so. I can send you more info (post your munged up email
addr and a note) or his contact info if you like.
