Oven Builders:

I've created an excel spreadsheet that will calculate the time it will take for the oven you are building to reach a desired temperature. All you do is enter the internal oven dimensions, the starting room temperature, the desired curing temperature and the total element wattage into the yellow boxes. The spreadsheet will then display the time to reach that temperature in the green box. It also displays how many amps an oven of that wattage will draw.

This calculator is based on an oven built with metal interior and exterior walls and 2" of mineral wool insulation.

This should help everone to have realistic expectations on how quickly their oven will reach working temperature.
