I have a dual element heater (lower) 1800w fitted on a Siemens oven. Unfortunately I did not find the exact part, the nearest I got was a grill element from another brand which is rated as 1300/900w. Would it hurt to fit this element please I know it will draw ‘some’ extra current but is that really so bad? Are there any other characteristics in grill elements that make them differ from lower elements that I am not aware of?
