What do our customers say?
After researching many other options, I decided the Aerotherm was best for my setup in an unheated hanger. No installation. No change to W&B. Easy to stow for transport or warm weather. My RCS unit is on speed dial and my heater is presently hooked up to my SR-22 awaiting my call.
I want to let you know that the unit is working great. It warmed my dead, cold engine and oil to 80 F in about 2 hours when the air was about 12 degrees. Now I can fly on all those cold, clear days.
The Aerotherm engine heater is exactly what I needed for my Columbia 400. I turn the unit on and it heats all my cylinder heads to about 100F and the oil is kept at a nice 85F. It is easily installed when needed and its simplicity makes it a great addition on to my aircraft.
I could not have got a better heater than your Aerotherm heater. I live in Hamilton Montana and have an unheated hangar. I leave it on all winter and everytime I go out to fly I don't have to pre-heat because its already nice and warm. We had 10 below temperatures here in December and the airplane stayed completely warm. It works great on my Citabria and I can take it to my fly in ranch in the Selway Wilderness of Idaho and run it off the generator back there.
I am a recreational pilot and have a RV-9 in an unheated hangar about 60 miles from my home. In 30 years of light plane ownership and experience with the full spectrum of engine warming techniques; bare light bulb, propane forced air, bolt-on heaters, floor mounted ceramic heaters, etc., I find the The AeroTherm Alien and RCS setup the best warmer available. I especially like the ability to control the unit remotely and use it only when I want to fly. There is no requirement for modifying anything under the cowl or having someone from the airport plug the unit in when I need it heated, or unplug it if I cancel.
