Quick questions
Is a Kat's heater better than Zerostart?
Neither brand wins every application. Choose the correctly listed fitment, wattage and connector. Where both catalogs agree, either can be a sensible option.
What size Kat's Hot Pad do I need?
Use the smallest pad that meets the manufacturer's oil-capacity guidance and fits fully on a clean, flat surface. More wattage is not automatically better.
Can a Kat's magnetic heater go on an aluminum pan?
No. Magnetic heaters require steel. Use an approved adhesive pad when the pan is aluminum and has a suitable flat area.
