E-Z Heat Aircraft Engine heater for the Model 440- 4"X 4" X 1/32" pad.

Note: Please see "Engine Application Guide" Click Here for the correct EZ Heat model number for your application.

Preheating engines for winter operations is at best a miserable chore and at worst can be a disaster for the plane, the pilot & flight operations - until the development of the E-Z Heat Aircraft Engine Heater. The E-Z Heat was designed to provide very efficient engine heating for virtually all propeller driven aircraft. The heaters consist of a flexible synthetic pad that easily conforms to the contours of the oil pan. This pad will heat 12 qts of oil from -40 to +60F in an hour while using approximately 300 watts of electricity. The heater is 1/32" thick. which enables the immediate heat transfer from heater to engine.

The heaters are thermostatically controlled, so leaving them plugged in overnight means the plane will be ready to go in the morning. Normally, complete pre-heating takes only 3-5 hours for the entire engine to be nice and warm. With this new lighted plug (110V models only, 220V models include no plug to allow for European outlet variance), the owner simply needs to look out the window or peek in the hangar to see if they remembered to plug in their E-Z Heat engine pre-heater. Molded into the male plug end is a newly designed light emitting diode (LED). This LED allows the operator to visually recognize if there is electrical power to the preheat system even from a distance. FAA approved for certificated aircraft.

End your cold weather starting problems and reduce premature engine wear.


The adhesive is already on the pad. All you need to do is peel and stick it on.

Preheat Time:
3 to 5 hours on cold soaked engine, although, since unit is thermostatically controlled, it may be left on overnight or all the time. Cowl covers and prop covers are recommended for extreme cold weather, they also reduce preheat time.

Lite Brite Plug:
With this new lighted plug, the owner simply has to look out the window or peek in the hangar to see if they remembered to plug in their E-Z Heat engine pre-heater.

Heat Transfer:
Convection/conduction, the safest way of heat transfer available. No flames or glowing elements are potential fire hazards.

    Installed on O-320-B2B. Make sure you have it lined up perfectly before you stick it on. I installed this when ambient was around 35 degrees. Have not tried leaving it constantly plugged in, but works very well. Plenty of cord to run it either way around the block to a convenient location.

    Q: Can I install your electric oil pan pad heater myself? Or do I need an A & P install it?

    You can install this yourself as long as you enter the installation in your log book. As this is not used during flight.
