Al Downs Posted February 20, 2019 Report Share Posted February 20, 2019 Are you in a CTSW or CTLS? On my CTLS's this is what I have done and it is still freezing. Blocked all holes including the large ones behind the seats. New door gaskets and checked for leaks afterward. Retaped the wing with Bolus tape Aligned the intake and replace the rubber around it. Checked to make sure the heat door in the duct is opening and closing fully. Used a smoke machine to find any leaks in the system. Applied rtv to all the leaks around the muffler. There were a lot of leaks there. Checked all the duct hose for leaks. Adjusted the carb heat and heat valves in the air box behind the engine. They were not adjusted very well. Retested the system with the smoke machine. All leaks sealed and the cabin filled with smoke thru the defrost and floor vents. There are no drafts but it is still so cold on cold days that you can only take it for about an hour before you can't fell your feet. Flying with heavy coats, pants and gloves is not fun. Much better on sunny days but with no sun it is miserable. Quote Link to comment Share on other sites More sharing options...
AGLyme Posted February 20, 2019 Report Share Posted February 20, 2019 Al, some of your questions answered: CTLSi model. The large holes behind the seats (access to the Baggage comp) arrived factory blocked with an industrial cloth. Gaskets are new, zero leaks around the doors, zero leaks around the air vents as well. Wings are taped (gaps) Per pre-flight inspections, no gaps in the intake My feet were warm on both flights. I fly with sneakers. Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted February 20, 2019 Report Share Posted February 20, 2019 Al, did you try sliding the vent windows open a little bit. For the heat system to work you need airflow. If you have the cabin sealed tightly you will not have the flow needed to produce heat, because once the pressure in the cabin builds up the flow stops.

Al Downs Posted February 20, 2019 Report Share Posted February 20, 2019 CTLSi is quite a bit newer maybe there is something different. Mine are 2008,2009 and 2010. They are all cold and I have not been able to get heat in any of them Quote Link to comment Share on other sites More sharing options...
Al Downs Posted February 20, 2019 Report Share Posted February 20, 2019 I am not sure if they have had the vent open a little. Will try that on next flight Quote Link to comment Share on other sites More sharing options...

Flying Bozo Posted February 21, 2019 Report Share Posted February 21, 2019 New vent to get the heat out of the mushroom and into the cabin! It is an automotive air conditioner vent. During a longer flight the mushroom gets so hot that the Dynon alarms and I had to turn off the heater to let things cool down. That is a vent near the pilots right shin to let heat out.

Roger Lee Posted February 21, 2019 Report Share Posted February 21, 2019 If the mushroom got that hot then you have a hose off or the feet outlets are misaligned. It leaves the mushroom interior via hose out the top of the mushroom or out the sides by your feet. Quote Link to comment Share on other sites More sharing options...

Flying Bozo Posted February 21, 2019 Report Share Posted February 21, 2019 The picture is a CTSW. Have a Muffin fan put in by Guttman. It blows in according to the design that he said was proper. Larry Quote Link to comment Share on other sites More sharing options...

Hmm...not a bad idea to take the diffuser off the vent, I'm sure the airflow would be greater. I'm sure I'll drop my keys in there at some point if I do it...

Roger Lee Posted February 22, 2019 Report Share Posted February 22, 2019 Like a computer cooling fan. The reason they went to the diffuser was everyone complained about burnt toes. Quote Link to comment Share on other sites More sharing options...

Animosity2k Posted November 11, 2019 Report Share Posted November 11, 2019 Ok! Thats what I thought, just wanted to make sure. Still getting very little air movement out of that w the knob all the way open. Annual is coming up within two weeks so I will have them check the damper on the cabin heat. Also noticed that the intake for the cabin heat does not line up well w/ the cowling at all which could have a lot to do with it. Quote Link to comment Share on other sites More sharing options...

I checked the butterfly valve on the firewall and it was working correctly. When I inspected the air plenum that feeds the heat shroud I noticed that the rubber gasket on the front is made up of individual pieces of rubber and not the one piece that is shown in the parts manual. When installing the bottom cowling, the bottom piece of rubber will more than likely position itself so as to block the airflow into the heat shroud. No air flow = no heat. Its easy enough to tuck this rubber piece under the cowl opening after the cowl is fastened and that fixed the problem of no heat. The guy I bought the airplane from did not know about it either. He said the heater did not work. I believe this could also lead to a lack of carburetor heat as well so its more than just creature comfort. Mike do you know if this rubber piece can be purchased by FDUSA? Mine is all cracked as photo'ed below and I think a culprit of a lot of heat loss?

Al Downs Posted December 29, 2019 Report Share Posted December 29, 2019 I have done all of that as well as sealing all of the leaks all around the muffler heat shroud and still not enough heat. There are a lot of air gaps around the muffler. I even installed new door gaskets. The only place not sealed is the tunnel that goes between the seats and there is leaks there but I haven't tried to seal that because of the cables going thru there.

I won't waste my time replacing this then. I'm thinking about just buying this and running it in the cabin on really cold days https://www.amazon.com/ZYYRSS-Defroster-Windshield-Cigarette-Windscreen/dp/B0818KFST7/ref=sr_1_3?keywords=dashboard+defroster&qid=1577656611&sr=8-3 Quote Link to comment Share on other sites More sharing options...
Al Downs Posted December 29, 2019 Report Share Posted December 29, 2019 If you can wait a few days I can let you know if a heater will work. I have one ordered and it supposed to be here soon. Holidays are delaying it a little. I plan on using it with a small motorcycle type battery Quote Link to comment Share on other sites More sharing options...

I plan on using it with a small motorcycle type battery I can wait, why would you just not run it off the outlet in the plane? Are you talking a much larger heater then I linked? I'd be worried of a fire with anything larger. Quote Link to comment Share on other sites More sharing options...
