It's a lot cheaper and much less complicated to get seat heaters installed into the co/pilots' seats.  Toggle on/off.  Multiple levels, nearly immediate on well before any engine source can deliver.  And no noise.  With an inline fuse, no need for a circuit breaker.  My copilot always loves the near instant on seat heat during early start up and taxi.  Can even preheat off the secondary buss prior to engine start.

LIVP (with seat heaters)


The Lancair Super ES (TSIO 550E) normally takes the cabin heat from the sonic venturi ports on the induction air system.  This does not provide very much heat, it is extremely noisy, and what heat is provided is lost in decent when power is reduced and the turbochargers  are not in demand.  In pressurized airplanes ie. LIVP and Piper  Mirage, the heat is provided through the pressurization system and  these problems are eliminated.

I have contacted Aerospace Welding Minneapolis, manufactures of several exhaust systems for many different GA aircraft, about making a  heat muff system for this engine.  They are willing to look at manufacturing a heat muff shroud that would wrap around the R/H exhaust pipe. We looked at the turbo crossover tube but there is not much clearance between the tube and the firewall.

Is anyone interested in this type of system for their TSIO550 powered  ES?  I am trying to get an idea of how many systems could be produced  at one time if a group order were placed.  Also, would anyone be  willing to part with their r/h exhaust pipe for evaluation purposes?

Thanks,
