For preheating, a flexible insulated preheater with integral magnets can be used which is similar to the ceramic heater but with three integrated magnets and a superwool insulation mat encased in stainless steel mesh and a stainless steel backing attached. The preheater can be used on both a flat or curved surface and is attached to the pipe by three built in limpet magnets The these three powerful magnets make a strong connection between the ceramic heater and the pipe quickly and with ease. These FIP‚ are used to preheat up to a temperature of 250 Degrees C.
