My water heater died, so I ripped it out, and decided to install a tankless heater. Both run off 240AC. Got everything hooked up, turn it on, and....pop the breaker. Ok, turn down the heat some, turn it back on, yay hot water, pop the breaker.
Right now I have the heater turned all the way down, and it will run for about a minute (with the lights flickering) before it goes pop. It is running off the same power line that was feeding the old heater tank, and it never had a problem. Could this little thing be drawing too much current for the double breaker its on to handle? If so, what should I do to get more power to it?
