Hey does anybody know what a water heater thermocouple generates ac or dc power. I think its ac but just want to be sure.

    DC millivolts

    amount depends upon whether it is a generator or a thermocouple.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    thermocouple voltage

    Standard thermocouples when new will register about 20 mv D.C A pilot generator such as a PG9 will register around 750 mv D.C. The larger are generally referred to as powerpiles or self generating controls. Powerpiles provide enough power to open a larger valve. In older systems it was the only electricity available. They used a thermostat with gold contacts to improve conductivity and work in harmony with the valve.Polarity on these systems were critical
    In a world of compromise , some men don't !
