I am routing my cabin heat hoses and the follwoing was braought to my
attention.

Presently I take the pressured air from my plenum, than to the heat
exchanger mounted on the exhaust and routing the heated air to the valve
which I can open for cabin heat or close it. If I close it, the air gets
blocked at the valve as I thought it is better to block it rather to dump
the heated air to the cowling. Reason for that is that I get the air from
the plenum and dumping it to the plenum reduces the available air to cool
the engine and reduces the pressure difference between the plenum and the
cowling.

Now a friend mentioned that I might get a heat blocking at the heat
exchanger with undefined consequences. So to say better dump the air to the
cowling rather than getting a cracked exhaust.

What is your experience / opinion ?

Thanks in advance,

Peter
