Answer 2

Same question as last time, do you want a timer which turns off and on with time, or a thermostat that turns off and on with temperature?

What voltage does it run off?

How many watts?

If you are playing with high voltages like 120 or 240 volts and liquids, this can be very dangerous. You can buy immersion heaters for a few dollars.
