Which system should I get?

* Temps are oF rise above ambient after 12 hrs, on our Cherokee 235 with Lyc 0-540. Aircraft was in our unheated hanger, the air inlets were plugged with foam rubber cowl plugs, the cowling was covered with a blanket which laid over the top and hung about halfway down the sides, and the sump had 9 qts of oil. The temperatures were obtained by a calibrated digital thermometer with a remote probe inserted between the top two fins on the center left cylinder, and a second probe dropped down the oil filler tube with the tip suspended at the 4.5 qt level.

Turbo & Turbo XP Systems

These are like the Standard System below but "Turbocharged" with extra power for faster heating and colder climates.

Turbo doubles the wattage on the oil sump  (50 w per cylinder + 200 w on oil)

Turbo XP doubles the wattage on the sump and the cylinders  (100 w per cylinder + 200 w on oil)

Turbo XP is our best system

Oil Cooler Heater Option

Standard System

50 watt band heaters clamp around the cylinders and a 100 watt aluminum HotStrip element epoxies to the oil sump.

Epoxy is included.

Oil Cooler Heater Option

HotBand Cylinder Heater System

50 watt band heaters clamp around the cylinders.  

There is no oil sump heater.

This system may be used alone or with any pre-existing oil sump heater.

HotBand XP System is the same as above except uses 100 watt elements

Oil Cooler Heater Option

HotStrip Oil Sump Heater System

Two 100 watt aluminum heaters epoxy to the oil sump.  

Thermostat limits the oil temp to about 150oF

Oil Cooler Heater Option

Our band heater puts the heat around the cylinder, and does not interfere with the CHT sensor.   The other brand heats the head with a bolt heater in the hole intended for the CHT sensor.
 

What about the other brand's claim that heating the head is best?

 

A big advantage of our system is that it is non-invasive.  All our parts are installed "on" the engine.  Nothing is installed inside the engine, and you do not need to remove any OEM parts or replace any OEM parts with our parts.  For example, one competitor's system replaces the OEM intake manifold bolts with their own heated bolts.  These are simply hollowed out bolts with heating elements epoxied into the hollowed out core.  Or they replace rocker cover gaskets with their own heated gasket.  As a general design philosophy we feel it is safer not to replace parts that were installed by the engine manufacturer, especially critical structural parts like bolts.

 

This is what the system looks like on your engine.  Note the band heaters around the cylinders, plugged into the harness which is clamped to the top center of the crankcase.  The AC plug can be mounted wherever you like but on this engine it is clamped by the front right cylinder so the extension cord can be plugged in through the air inlet.
