I plan on that because my Onan is air cooled and I use wood for heat.
With a water cooled, I would even think of moving the radiator to the
place the heat can be used so it would be remote and then safer.

Any leaks in the exhaust or head gasket could result in CO problems.

Make sure the crawlspace is blocked off to critters, or it may become the winter
spa.

A water jacket around the exhaust pipe could pick up a lot of useful heat.

I have an air cooled engine so plan on having a CO monitor due to those
issues.  I may not be able to even do it with my old generator.

If mine was watercooled, I would move the radiator to a remote location
so fumes wouldn't be an issue.

I like the waterjacket idea, my 3 battery packs now charge in a 6 hour
cycle, some free hot water is always nice.

We are boxing in the crawlspace well and have two cats that enjoy
critters...for breakfast.

The biggest amount of heat you can recover from an IC engine is from
the exhaust. You would need a stainless steel (or other non corrosive
material) heat exchanger and would heat water.
75% of the energy available from the fuel goes down the exhaust pipe.
Heat from the oil can also be recovered in large setups.

What about a simple coil of 1/2" flexible copper pipe wrapped around the
muffler with some muffler insulation tape or even a stove pipe piece
over it for a heat exchanger?
