As you can see by my post it's the new year and I must be bored this morning.
The weather is cold and time to talk about keeping warm in the cockpit. I can fly in 25F temps with only a pair of bluejeans (501's of course) and a short sleeve shirt. Here's how to maximize your cabin heating.
First you need to make sure that your cabin heat is opening all the way. This and air leaks is the major cause for you not getting a good heat delivery to the cabin. Pull the cowl off, pull the cabin heat knob all the way out and from the right side of the plane look and feel to see if the little diverter door to the cabin heat is opening all the way. If not adjust the cable a tad shorter. If your diverter door isn't opening all the way the cold air is mixing with the hot air and you are loosing a lot of heating capability.
Second take some 2"- 3" wide clear plastic tape and tape over the holes up above your head in the cabin on both sides. I mean all the holes including where the wing pin handles are too. All these holes need to be sealed. Sealing only a few will only force cold air out of another hole. Make sure that you have the wing root gaps on the outside of the plane taped over with your white bolus tape , too. Most of us already have this done.
If you don't already know many of your cabin doors do leak some air, some more than others, but either way they allow cold air in. Go to the hardware store and get some 3/8" soft weather strip foam (not the harder black rubber). Apply this to theedge all the way around each door up against the black door molding all ready there. Now that you have no cold air entering the cabin the heater works very well.
These few little procedures will keep you nice and toasty for the cold weather flying.
If you want to take sealing the cabin one step further you can get a 2' square piece of 2" thick soft foam and cut it out to the shape that fits right behind each seat that is open to the baggage compartment and fill/seal this area off, too..
