IFLYIFR Posted January 31, 2022 Report Posted January 31, 2022 I keep my M20J in an insulated hangar. The hangar is not, however, heated. Outside temperatures have often been below zero (-12 to -5) this month; the temperature in my hangar has usually been between 30 and 35 this month (it was 26 today inside). There is no cell phone coverage at my hangar for a remote on/off power switch. My question is what is the best way to use my Reiff engine heater. Option 1 - leave the engine heater plugged in continuously every day/night, even on days when I’m not flying. Option 2 - drive 30 minutes each way to the airport the day before to plug the heater in overnight (not convenient but doable). Option 3 - connect the heater to a timer that turns on every morning for 5 or 6 hours then turns off (more convenient but the engine would be heated then re-cooled every day). Option 4 - something else. Thanks Sent from my iPhone using Tapatalk
wishboneash Posted February 5, 2022 Report Posted February 5, 2022 I have a temperature controlled fan/heater which sends in warm air from below the cowl flaps. The engine is at a fairly constant temperature of 18-20C. The probe is placed inside the air intake on the top of the engine. I also place a blanket on top of the engine to provide some insulation. The heater only comes on when necessary so there's no unnecessary heating on warm days.
