With 20 degree temps in 2 hours I am showing 85 degree oil temp at start up.With a moving blanket on top of cowl the entire engine is warm to touch and it fires right up. I am very pleased with the dual pads and thermostat and would recommend that set up. I need to look into the cell phone switch. Thanks Ron

We will soon offer a similar cell switch for about half what others sell them for. Maybe less if purchased with a preheat system. I've been testing a prototype and it works very well, for $3 a month T-Mobile service cost. It makes a preheat system much more convenient to use.
Ron, we are now offering a cellular remote control switch. It's ready to use, no wiring or assembly required except for installing your SIM card. We are selling it only to our preheat customers, at our cost ($89).

I recently pulled two ECI Titan cylinders with 300 hours on them for an unrelated problem on 55BC but I was startled to find significant pitting on the cylinder walls directly under the Reiff cylinder band heaters. I think the Reiff cylinder band heaters are excellent however I am now never going to leave it plugged in for any extended time period.

Default Personal opinion

Reiff is overkill for temperate climates at least.. We don't very often below freezing here in Western Oregon (Vans country) but I simply bought 2*45W stick on sump heaters for the ears of my forward facing sump.

With colw plugs this is enough to raise the oil temp 30F and the whole ingine gets warms even around freezing... They were pretty cheap too and I've had them since 2006 running pretty much all the time.

Can previous customers of your Reiff preheat systems get this deal? I've got two of them installed now, one on the 172 and another on my 9A.

I bought a 1500W ceramic heater from Home Depot + some ducting and used pop rivets & screws to mate it all together. $40 total.

On the high setting, this heater soaks everything under the cowl nicely. Oil temps are 100F+ and cyl head temps are 120-130F.

The heater is on 24/7 and is put on right after shutting down the engine. The airplane is in a unheated hangar less than a mile from the Pacific Ocean, and it has really cut down on the external corrosion. The air often gets really wet here and this heater keeps the dew point spread large to keep any moisture from condensing inside the cowl. It's so hot you can't leave your hand on a cyl for more than a few seconds.

As for the internals, there have been a couple good articles already posted in the thread regarding the validity of keeping the entire engine (not just the oil) warm to combat internal moisture and corrosion. I'm happy with the results I'm seeing.

Here is the heater with ducting bent up and riveted:


Just put the outlet in the lower cowl opening and point it towards the sump.


Oil temp is ~110F


Cyl head temp. Don't pay any attention to the labels, they are just for fun.
