ENGINE PRE-HEATERS
 

Hello Gents

I just bought a Switchbox and I will need to install a Preheater Pad on the sump on my RV-4 and was wondering which one do you guys would recommend...

I don't fly the aircraft in the winter so one for Fall temperature will be good enough

I'm leaning toward the Reiffs or the E-Z Heat....

Thank you for your advise

E-Z heat for me
 

I live in MN and have the E-Z heat sump heater on my IO-360 A1A. My oil temp was always in the 90's even down to 10 degrees Fahrenheit. Sump heater was easy to install. I also use the switch box and turn the heater on the night before I plan to go flying. I also cover the cowl with two moving blankets and have cowl plugs.

When I was up north I loved my Reiff heater!

Cyl, oil cool and sump for the cold NY winters.

Still got it installed....but it just doesn't get that cold anymore :D

EZ-heat ... works sitting on the ramp down to -10 ... oil temp was 50

I installed Reiff due to its temp limiting feature. Also got the cylinder bands. Nice construction and instructions. It is not flying yet, but fully expect to meet website reported performance.

I have a Reiff also. It works great in MI. Tim

EZ Heater
 

I use the EZ Heat Engine Preheater from Aircraft Spruce on my engine with the cell phone SwitchBox. I turn it on 2-hours before I want to fly and typically have 80 degree oil temp in the runup area before takeoff.

NAPA makes a cheaper version but some are without the 3-wire ground plug.

I believe that the EZ Heat I have is 200W so something similar that is 200W should work.

I am using a oil pan heater for a tractor on my oil sump, same as the E-Z heat set up. Works great, purchased from Amazon. I use a simple timer that turns it on 3 hrs before I want to go. if you cover the cowling with a blanket the whole engine will be warm and happy.

I am using an oil pan heater off amazon and a cell phone switch similar to the switchbox but 1/4 the price and has 3 individually controlled outlets. Total cost $70 and works flawlessly
