Looks pretty cool...I mean Hot!

Scuba raider I still like yours but could not find it....it looks like it wouldn't be that hard to build...j

I have a heater core with 2 computer fans blowing through it that works pretty well but it is nowhere 10 lbs. I couldn't stand to add 10 lbs for a heater.

Found this oil cooler with fan, going to use it for cabin heat in my rotary engine RV7. Weighs 1.9lbs with fan, measures 4"w x 6"l x 4"d, cost about $145 shipped to your door. I was very happy with the quality of the product as well.

Best,

Seat Heater

Postby GDS » Mon Jan 09, 2012 11:12 am

I brought this topic back because I've got the heater kit for my Highlander but not sure if it will be enough.

Does anyone have any experience with electric seat heaters like these? http://www.checkcorp.com/seat-heater/seat-heaters.asp

An obvious concern is power. I pulled this from the FAQs on their website:
"HOW MUCH POWER DOES THE AVERAGE CHECK SEAT HEATER SYSTEM CONSUME?

3 to 5 Amps. At 13.8 VDC or 41 to 69 Watts
."

Electrical systems are my weakest skill, but it seems like it would be manageable with a Rotax 912 electrical system, although may have to be selective if both seat heaters were cranked to full power.

Thanks, GDS

I don't know if it is good-bad helpful or etc., but the local mechanic said these were used with good results on Rotax-fitted birds: http://www.vintageair.com/catalog11/pg51wc.pdf

OK I'm really going back to the past now but I've hit another crossroad and I need some help from my friends. My Highlander is a tricycle with a Rotax 912 and a Toucan exhaust system. The Toucan system has two mufflers. Each has a Muff to provide cabin heat. I have several ways to go here and need your recommendations.
My options include:
1. Since I already have a Just aircraft heater kit I could just install it on one muffler .. Incidentally thanks for your great pictures.
2.Or I could run both muffs into a Tee and into a single duct ...or would the muffs more or less cancel each other out at the tee. Maybe a blower would help.
3 Or I could get another airflow director , some more scat tubing, and run the muffs independently to either side of the aircraft
(I thought "Scat" was a trail of animal poop)
4. Or if you don't like the system that much I could go with a radiator core, antifreeze from the engine, blower, etc. ...the expensive solution.

So...Thoughts?

P.S. iIn former posts there was discussion about stuffing the muffs with stainless steel scrub pads to improve heat transfer.
In his book "Firewall Forward" Tony Bengalis, a kit builder God, recommends wrapping the mufflers with screen door spring. Hot idea!
Plan not to be the first at the scene of the accident!

I went the radiator core with a blower route. Never, never regret it during winter flying. Especially when taking my wife up. I get the awwwwwww statement when I turn it on. :mrgreen:

What parts did you choose (heater, fan, tees, valve, switch)? How did you plumb it? Any pictures?

Hmmm... Dennis, no disrespect intended but does winter flying in Georgia really count as winter flying?
I live in Minnesota and I'm considering installing a wood burning stove in my Highlander. Or maybe I should just spend Nov - April with you in the south.

Dan,
You beat me to it LOL

I find the stock heater OK down to about 15F or so. I do have a heated vest, that helps a lot. Michigan winters can be cold and snowy, especially by the lake. Should be able to put the skis on in another month or so. The biggest cold air leak I found was near the rear spar and flap closeout. Made some plugs and its 90% better.

HAHAHAHAHAHA....yep it is all relative. I do live in the North Georgia Mountains so elevation does play a part but NO comparison to what you guys deal with. :shock:
I will have to go back and look to see if I have some clear pictures. I remember I got it off of Barnstormers as one fan unit. I put a switch on the panel and just flip the fan on. Was a bit tricky plumbing it to the radiator though. I mounted the fan under the panel inside. It will slap run you out even with the many air leaks around the doors. :mrgreen:

Found a link to the heater Dennis has installed in his aircraft. No price listed on the page, you'll have to give them a call.

Because I live in Wisconsin where it gets cold enough to drive your car on frozen lakes, and I really enjoy ski flying, my new Highlander will have both 2 heat muffs off exhaust, a large heater core with fans, and will be well insulated along with an insulated cover that closes off the baggage / tail area. I flew an Avid on skis once where the guy had bofh exhaust muff heaters and a heater core (he used the heat muff pressurized air through the heater core rather than using fans). It made so much heat it had to be turned down any time the oat was above zeo Faherenheit. It was so impressive that I decided on my next plane I'm going to have both heat systems like his, but with additional insulation. My wife will want to go along more.

Also worth mentioning, I discovered on E Bay a variety of ready to install coolant type heater kits are available for recreational vehicle UTVs like Ranger, Mules, Razors, etc.

Weight addition? Who cares, I'll go on a small diet to offset it :mrgreen:

Hi Guys

Well,it must be getting cold again since some of us seem to think we should be warm like lying in front of a fireplace with a few logs burning and a glass of our favorite beverage at hand. But the bad news is it ain't going to happen in a Highlander. The first thing to do is look around you and you will notice an acre of lexan and VERY thin fabric between you and the outside. So much for dipping myself into this conversation. Now I will tell you just from my own observation how I have stayed warm. First I have spent 15 years flying in interior Alaska freezing in a Super Cub counting moose at -35 to being toasty warm at 250 in a King Air at who knows what temperature since I was warm and comfy. There are some pictures of my setup in page one of this thread. I have found my dual Toucan setup more than adequate for my feet. If I can keep my feet warm the rest is keeping the air leaks to a minimum and proper clothing. For air leaks I take a half inch roll of weather stripping and use as needed. When it warms up just peal it off and your ready for Spring. I know some of you have some very nicely fitted doors and windows. Mine are probably not as tight as they could be but I'm not going to re-engineer them when weather stripping is so cheap. By the time its down to the single digits we're talking snow pants, insulated everything and preheating and a bunch more stuff. Now I know why old people move to Arizona. So much for my comments for the day. Just remember KISS.
