Home Distiller

I have a heater I got from a hot water system, it is 3600 watt and I intend installing it in a 40 litre keg. How do I go about adapting a temp control to it? would a dimmer switch do the job?

Dimmer switch for the correct amps and handling that wattage will cost you some $$$.

Do a search on "triac". There is plenty of info.
