 I have looked at your  heater and it is in principal the same as mine and many others.  That is  taking the warm air off the rear of the water radiator.  Mine is fitted but  not operational (fire wall phenolic is bolted over the outlets of the SCAT  tubes)

  

 The reason for this is  that Francis Donaldson (LAA) insists on a fire stop valve at the point were the  tube passes through the fire wall.  One builder, Mike Parkin, has made  up some very expensive petal valves to achieve this.  See attached.  I  am still looking for a cheaper and simpler solution to these  valves.

  

 Obviously US regulation  is not the same as ours.  What are your thoughts on a) the need for fire  stop valves and b) a simpler cheaper  way of achieving a fire  stop?

 Working on that with better access for fuel tank, controls, mods or  repairs.  The cockpit module is heavy and requires a lot of help to get it  in right and it is very time consuming to build for the novice, and for the  company to construct.

  

 Keep the ideas coming.

 Go to my website and download the heater.  One inch tubes is all you  need really to keep the plane warm.

Here’s my method of maintaining firewall integrity.  The brass colored item hooked between the two tabs is a fusible link (McMaster-Carr part number 1147A14) with a melting point of 100 deg C.  The stainless steel flap employs a hinge with a spring to snap it shut once the fusible link melts.    This takes more space than Mike’s scheme but it is an inexpensive solution.

Hi Guys,  

   

I note your comments on the heater system.   I have to say that my experience with the system has shown it is not as effective as you might imagine.  The problem is that it works fine in the climb when the temperatures are up,  but in the cruise, my 914 will cool right down and then the heater is ineffective.  

   

The cooling system on G-JULZ is just too effective in the cruise and it concerns me that the engine is running for lengthy periods at temperatures well below 100degC.  I have a modification in progress to introduce a cowl flap in the cooling air exit in an effort to control the engine temperatures.  If it is effective I am also developing a micro-processor  temperature control system to make the whole system automatic.  

   

If this mod works then, the heater will hopefully become more efficient.  

   

   

Regards,  

   

Mike

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  I use an expensive and fully lockable cable which holds the flapper shut  because I fear the same problem.  That shuts off the fire inlet at the  duct.  I draw the air from a low risk fire area, but not a perfect  solution.  

  

 If I had regs requiring a stop valve, I would make it from stainless as a  box with a flapper in it.  Aircraft Spruce has a heater valve which I would  use as a guide.  Theirs is made of aluminum.  Let's face it, if the  aluminum melts because of a fire, you're in serious do do.

Spruce supply a stainless valve as well.

 Thanks for the comments,  My thoughts entirely regarding aluminium melting
