IT SURE WOULD BE WONDERFUL IF SOMEONE COULD TELL ME HOW TO CHANGE 220V TO 110V ON THIS TITAN I HAVE. I DID IT WITH MY TANK WATER HEATER BUT HAVE NEVER DONE IT ON A TANKLESS. ANY AND ALL HELP IS VERY MUCH APPRECIATED!!!
why would you want to change it over?
well, if the tankless takes 90 amps at 240v, it will take 180 at 120. same power, so therefore you will have to put in a HUGE power cable for it.
