[QUOTE="ProDave, post: 286664, member: 6969"] P = I x V is indeed correct. But more important. P = v2/r (Voltage squared over resistance, can't do superscript on the forum) The resistance of your immersion heater remains the same. So by running the heater on a lower voltage, it will consume less power. Apart from losses, power in = power out on a transformer, so the power in to the transformer will be just a little more than the now reduced power of your immersion heater. So a 1KVA site transformer will be plenty. In my case, I had a 500VA autotransformer. I little under rated but I tried it and it works, and it hasn't melted. yet. [/QUOTE]
