Hey Al;
I have had that same suggestion made
to me, but to make sure there is a valve, readily accessible to shut it off if
it leaks, makes sense.

We've been
looking at the same things with our install. We talked to our exhaust
guy, and he feels that with the exhaust temps that these rotaries have, that
it might not be a good idea, (the muff). Next step was hot water,
plumbing, and a heater core inside some where, which was sort of a negative
idea. We kept all of our cooling lines exterior, so that a coolant leak
wouldn't happen inside at about 10K feet, and 200+ knots, not a good
scenario. J.C. Whitney has a small electric heater that has some
possibilities, so we are looking into that and some other
ideas.

Greg;
Having studied that
option in the past; I’d suggest you save your time – unless you want to add
another alternator. For effective heating you’re going to need more than
1000 watts. For a 14 volt system that’s over 70+ amps.
I don’t consider it
a risk to run some relatively small diameter, high quality, heater hose (5/8”)
into the cabin to a small heater core. I have a 7” x 7” heater core, and
it puts out at least 1500 watts, or more. See Mcmaster-Carr silicone hose,
part #5296K12. Pressure test your system each annual to about 35
psi.
