Model #1325 measures 5"x7"x.075" and consumes 500watts. It is best suited for larger capacity oiling systems holding 3-6 gallons. The Duramax oil pan does not have enough flat surface area to mount this unit.
PROHEAT pads consume less electricity than frost plug/block heater counterparts. Frost plug/block heaters take hours to install with a variety of tools -- PROHEAT pads install in minutes without any tools and are permanent. A typical frost plug heater consumes 600watts while a 6.6l Duramax heater consumes 1000watts. Most applications can be covered by a Pro Heat Model # 512 which only consumes 250watts. PROHEAT pads are SMART, SIMPLE and COST-EFFECTIVE.
