Cabin Heating and Air Vent

Post by glennpretorius »

My Cabin Heat is not very effective, more heat into the cabin would be nice

I have found some fresh air leaks between the NACA scoop air intake pipe and the connection at the back of the Plastic air vent in the panel. This i have resolved and it makes a difference as that air which was leaking at the join effectively mixed with any warm air from the cabin heat and cooled it down.

Unforunatrly air from the standard vent cannot be closed off completely. Even when closed the vent leaks fresh outside air.

Does anyone have advice on another type of vent that can replace the vent.

Hi Glenn,
I just started dealing with this issue in my Sling 2 now that it is cold. I stuffed T-Shirt material into the vents from the outside the best I could. On the left side I needed to get the material behind the OAT. This cut down the leakage from the vents a lot. Make sure on preflight that you check these because I discovered some of the t shirt material sneaking out. I am assuming when spring comes taking these out will be easy with a shirt hangar or long skinny medical clamps.

For the heater I find that it heats the passenger side better than the pilot side. No solution there yet except thicker pants and socks.

Thanks for your info.
I eventually sorted the problem and heater works very well
I removed the right hand vent ( air was leaking behind the panel where the silver ducting attaches to the vent - there are a couple of square cut outs that were not covered by the silver ducting ) you have to carefully pull the air vent out , then just pull the ducting pipe enough to make a snug fit , then re insert the vent . Be careful not to damage the panel or air vent . This solved the outside air from the NACA scoop blowing into the pedal area of the cockpit.

As for the cabin heating problem , there was a connection problem involving the exhaust muffler and air intake for the cabin heat. This was sorted out by the. AMO. The hot cabin heat air is directed more to the right side of the pedal area,
The cabin heat system is now working much better than expected and have found it very effective.

Thanks for that suggestion. I'll have to look into this and see if I have the same or similar issue.
