I'm making a system that is going to heat water in a 25 liter tank to a given temperature and keep the water on this temperature with a precision of +/-0.5 degrees Celsius. As I have done some research i have decided to control the heating element with a zero crossing solid state relay and control this relay with an Ardunio. The heating element is 230VAC 3kW.

My question is, for how long can I run constant current through the heating element without overheating it? I mean, if I turn the hot plate on my stove on max, will it run constant current through the element or will this still be pulses and how to determine the pulse width and time between these pulses?
