Calculating the wattage requirements to heat a system is a straightforward process as long as all the possibilities of heat energy flowing in and out of the system are considered. Heat requirements that must be considered are:
* Initial heat for startup of the system, usually from an ambient temperature to a desired processing temperature.
* Losses due to materials changing phase, either during initial heatup or while processing (melting a solid to a liquid or boiling a liquid to a gas).
* Heating of material being processed during operation.
* Heating of material flowing through the process such as a liquid that will be heated and ...
