From: "clivesutton" 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 . . .) https://www.lightaircraftassociation.co.uk/engineering/TechnicalLeaflets/Mods%20and%20Repairs/TL%203.17%20List%20of%20approved%20Prototype%20mods.pdf Read this topic online here: http://forums.matronics.com/viewtopic.php?p=477894#477894 ________________________________ Message 2 _____________________________________ Time: 06:53:04 AM PST US Subject: Re: Europa-List: Re: Europa Cabin heater.

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 http://contrails.free.fr http://lapierre.skunkworks.free.fr ________________________________ Message 3 _____________________________________ Time: 11:39:57 AM PST US From: "Greg Fuchs " Subject: RE: Europa-List: Re: Europa Cabin heater.
