Overview
| The E-Z Heat Engine Preheater system fits the Rotax motors and many other light sport aircraft on the market today. The system consists of two heater pads connected with a common "Light Bright" power cord. Installation is easy by peeling and sticking a pad on both the sump and on the oil tank to assure the engine gets the proper amount of heat. |

Only used twice but works very well. Exterior of pad gets very hot, up to 600F degrees is acceptable per manufacturer. About 2 hours to get oil from 45 to 110F. Manufacturer states it should thermostatically maintain 120-160F.

E-Z Heat Engine Heater 912
Great product , went on easy and really does the job. It was -22 this morning and my oil temp gauge read 95 degrees and the CHT gauge was at 71 degrees. Best heater for the money here. Have a friend with another brand with bands around cylinders and his temps were both below 0 degrees and it would not start. He now has the E-Z Heat system also
works great very easy to put on, excellent product for the price.
Little tough to install on the oil tank. Doesn’t adhere on end edges well. Poor instructions but seems to do the job

It seems to get very hot and keeps the oil very warm. The first one I got was defective and burned up I think the thermostat failed but aircraft spruce was great and replaced it for me . Installation was easy . Instructions are not that great and I think they should have a you tube installation. I had questions like where exactly to place the tab on the oil pan and oil tank. Where should the cords be routed and how much should stick out ? How much sealer to apply? I flew today with a warm engine it was nice.
I've used EZ Heater before on other applications With expected results good. On the 912 applying the pad requires contouring to oil tank which did not go well. As I mentioned before with Lycoming use no problems and experienced years of use.
I used this kind on a Cessna with great results. The Rotax model is hard to install with limited instructions. The stiff pad will not roll onto a cylindrical tank (even when heated by plug in and hot air gun on warm surface), and the one for the bottom of the engine is slightly too wide. Mine smoked when I plugged it in, probably from the crack induced by installing it on the tank, so I removed it. Wasted money - I just ordered the Reiff model. Its worth the extra money to get something that will work. A shame, because flexibility and proper sizing would make it the choice.

Per the supplier: 300 Watts total.
Per Vendor: There are instructions but you can tell him one pad goes on the oil tank (bottom, you can wrap it around the bottom below the oil level) and one goes on the engine case ( also on the bottom ). They just have to be within the oil line. It usually takes 3 to 5 hours to completely warm the engine but it depends on the outdoor temperatures.
Yes, you can as long as you can fly once or twice a week.
There are two pads and they each measure 6" x 1.5"
It would depend on the ambient air temp and the aircraft temp but usually 3 hour or so. 5 hours max if its really cold.
Most are around 2.4 amps. The 2 pad is 2.58 amps.
