Show us a picture of your Home made pre Heater

[RV10Pilot]

My hanger mate allows me to borrow his. Way overkill, but it will warm up the engine quickly. I use it on the lowest setting, being careful not to damage the paint. (sure wish I could figure out how to rotate an attachment)

My DIY preheat is shown here. Able to turn heat or AC up or down from an app on my smartphone.

I use a hair dryer in each cowl inlet inserted into a piece of foam - petty simple. I use a cellular switch to turn them on 15-30 minutes before I want to fly (depending on outside air temperature). I've used this setup here in Iowa for 12 years on my 7A, and over 30 years on my other homebuilt. Every ten years or so I need to replace a hair dryer - slide one out, slide one in.

Be careful with milkhouse heaters if they sit on the floor. We had a local guy develop a fuel leak and it was ignited by his milkhouse preheater. It completely destroyed his plane and ruined two others in adjacent t hangars. My hair dryers are well above where fuel vapors would accumulate - plus the hangar is well "ventilated" (not well sealed!!).

No question….a great solution. IF one had internet AND insulation AND air conditioning AND a lot of $$$ to pay the utilities and hangar cost. For the rest of us….it’s whatever we can scrounge up out here in Dogpatch.

For awhile last winter, I had a big (for me) avionics project, and to keep warm I brought in a couple of 120,000 BTU bullet heaters. They did a good job of keeping the hangar warm enough to do a few hours work. The downside, in my un-insulated corrugated-sheet metal T-hangar, is that it melted the snow on my roof and it promptly ran down the front, flooded the front of the hangar, and froze the hangar door to the shut. I ultimately was able to persuade a buddy to swap hangars for a few weeks (his is insulated and heated). After I chipped my door open, I moved my plane out and his in and finished the project basking in the luxury of natural gas while the temps outside routinely plunged to -20F. I shed tears when I had to move out and swap back.

Lesson learned. It was fun to see how the other half lived.

i need to take a pic of my $5 electric frying pan from goodwill.put all the tools you are using in the pan. like someone said cold tools are cold.

Here is my heater, I only use it when I’m at the hangar. I install cowl plugs and it doesn’t take long to warm it up.



I installed a sump heater that I plug into a timer if I want it to come on before I get to the hangar for the Saturday morning Breakfast flights.

I just built a new 3000W version using it on different planes. So the height is adjustable and the heater itself can be swiveled. It works very well and blows into the air outlet heating up the whole engine and battery if installed firewall forward. For the A-models there is probably a different adapter required. My only concern is when the fan fails it could overheat and is then a fire hazard. I might install a second fan just in case.

This is a 900w interior car warmer, metal casing, mounted on an aluminum base. The extra lighter gauge 'flap' clips over the cowl pins to hold the heater in place. Compact size makes it easy to pack, has proven effective in Canadian winter for 10 years.

A ceramic 1500-3000W heater, few cheap ventilation accessories, some soft foam. I just build the composite cone to connect heater and ventilation connection.
