Gents,
You may know that the UK Europa Exhaust suppliers CKT are working on an exhaust-muffler
mounted cabin heater. I helped MD Chris Piper to package it using my
XS-FF/912S installation and made a couple of cardboard prototypes for that purpose.
As a result, a fabricated stainless 'intake box, muffler shroud and firewall
flap-valve that are almost production-ready, now exist at CKT. AFAIK no
(LAA) paperwork supports it yet though - but for our non-UK friends in really
cold climes, it may offer at least some ideas?
BTW some rudimentary calcs of my own showed that the exhaust-muffler mounted solution
really can capture several kW of heat power (=too much heat?).
email me separately if you'd like a few pics of the prototype solution (as for
some reason i cannot add attachments . . .)

Hi David,
I understand your concern.
The cabin heat described in Contrails ! is very simple (1 door, 1
control, 1 duct) and efficient provided that
- Your aircraft has an adequate radiator duct
- The water/oil temperatures are adequately regulated with a cowl flap
If not, (leaky duct or no duct, unregulated temps, oil/water thermostat
leading to low radiator temps, etc.) you'd have to first sort out the
engine cooling system or resort to the heat muff, heated vest or seat, etc.
Please note that to be safe, a heat muff must feature double walls,
otherwise it can lead to direct ingress of deadly fumes into the
cockpit. Also it only works when the engine is delivering considerable
power.
And of course the installation is not as simple : air intake, double
walled heat muff, valve box, hot air duct to the cabin, hot air dump,
control linkage.
In any case, the passage through the firewall must be gas and fireproof.
All the best with your decisions and your project,
--
Best regards,
Gilles

Sure, using a Sky-Tek heat muff and Aviacomp DL-025 cabin heat box.

That doesn't look very simple.
Anyone use an exhaust muff and ducting?
