AeroTherm - Aircraft Engine Heater Systems

Heating Times on a cold-soaked engine

32◦F and Above: 90 minutes

32◦F and Below: 3 hours

Heating times are based on AeroTherm use in a closed hangar.

Why should I use an AeroTherm Heater?

The AeroTherm is a whole engine heater, meaning it evenly heats all engine components to the same temperature. Because airplanes utilize cast-iron engine cylinders, it is important to heat the cast-iron to the same temperature as the aluminum pistons. Uneven heating of the pistons results in piston scoring. This occurs when the pistons are hotter than the engine cylinder. This problem is typical of oil heaters which also cause condensation due to uneven heating.

The AeroTherm eliminates condensation and piston scoring thru its patent-pending, heat-circulation technology.

Take-off demands 90-100% of an engine’s horsepower, and for this reason, it’s vitally important to properly warm the engine. Proper pre-heating reduces wear and tear and substantially extends the life of an engine. Idling is not an effective way to warm an engine. When idling, the propeller forces cold air back across and through the engine compartment keeping a cold engine from heating properly.

In short, The AeroTherm is your best option for pre-heating a cold-soaked aircraft engine prior to flight.

Do I need a thermostat?

No, The AeroTherm heater has a built-in thermostat with an auto cold setting of 45 degress

Can the AeroTherm heater be run on a timer?

No timer needed! The AeroTherm Heater has a built-in thermostat which will cycle on and off as needed.

How big is the Deuce?

Fully assmbled: 7" H x 6.5" W x 38.25" L. The Heater: 6.5" H x 6.5" W x 12.75" L.

Every AeroTherm heater ships with a durable nylon suspension band that attaches to the prop of your aircraft.

It also includes a floor stand for heating from the bottom cowl vents. We recommend this for the Cessna 182.

The heater will warm 120 sq. ft. to 120 degrees. Since most engine compartments are substantially smaller, the heater can be used on virtually any small aircraft. To maximize warming, the cowling/engine compartment should be sealed. SEALING IS IMPORTANT! You can cook a pie with the oven door open, but it will take a lot longer. We suggest using a blanket or something as simple as a sleeping bag to help retain the heat. This simple step increases efficiency tenfold.

Will the AeroTherm heater be effective if my plane is parked outside in the wind at extremely cold temperatures?

Yes, if you cover the engine compartment with an insulated blanket and make sure your bottom cowl holes are plugged. (Always remember to remove cowl plugs before flying)
