Remote Heater Controls: Switchbox a Top Value
In our March 2013 article on external engine heaters, we noted that there is disagreement among pilots regarding keeping a heater plugged in all the time versus using it only in preparation for a flight. While we do not take sides on the matter, we note that a lot of pilots are concerned about engine corrosion caused by running an engine heater constantly, so they only want to use the heater in preparation for flight.
