"I'm very happy with my Aerotherm Ryan, easy to use and silent. Hook it up, do my walk around and prep and in half an hour, 45 minutes it starts like a Summer day. Preparation and proper procedures are so important with a Radial Engine. Living in Canada with colder winters I feel confident I'm doing one of the best things I can do for my ship."
After doing a lot of research on aircraft engine heaters, I came to the conclusion that the AeroTherm heater was my best choice and the only unit that met all of my purchase criteria: effective, lightweight, portable and inexpensive. I had decided that I wanted an electric heater and, since I fly a variety of aircraft, I needed a unit that was not permanently installed. I like the fact that the AeroTherm re-circulates heated air throughout the engine compartment, ensuring that the entire engine is heated evenly, including the oil. And with three different temperature settings and a built in thermostat, I can tailor the heater output to my specific needs on any given day.
It is 2 degrees today. I checked on my plane in the unheated hangar. The aerotherm was working great. I had it set at 65 degrees. It was cycling the heat on and off, ever so slowly. I'm very pleased with the aerotherm.
Absolutely delighted with my new Alien heater. Hooked it up last night and when we got to the hangar today the engine was warm as a summer day and it fired right off with no strain despite an unheated hangar and ambient temp of zero degrees F (-18C). Goes on and off the airplane in less than 20 seconds. Custom hoses fit perfectly. Excellent concept, design and execution! Great product; worth every penny in reduced engine wear and convenience. Thanks!
We’ve used the heaters 3-4 nights a week since we’ve gotten them. They allow us to leave the planes in the storage hangar regardless of the temperature. In the past we tried to get at least one plane into the heated maintenance hangar the night before a cold morning flight. This was always a complication and didn’t always work. Now, all we do is hang the heaters on the plane after the last flight and plug them in before we go home. The pressure carburetors on the Helio Couriers don’t like cold starts and it wasn’t unusual to have to pump the primer to keep them running initially on a cold morning. Now, we pull the plane out and turn the master on and see 70 – 80 degrees on the CHTs with the thermostat set at 70. The oil temps are 65 to 70. We will probably buy two more for the 206s before next winter. Thanks for a great product.
