Stef's Confined Element Oil Preheaters

Stef's confined element oil preheaters put an end to any worries of boiling oil, or the separation of suspended minerals, paraffins, and other oil additives. This design isolates the element itself from direct oil contact within a stainless steel housing containing highly heat-conductive material. These heaters will increase the temperature of five quarts of oil by 50 to 60 degrees F (depending on the viscosity and ambient temperature) in 15 minutes. A 3 ft. power cord is included.
