palmettoinspect Posted March 22, 2016 Report Share Posted March 22, 2016 I ran across these three tank electric water heaters in what looks to be an attempted parallel install. In this set up the most demand is put on the center water heater with the shortest run as the path of friction is not equal between the three units. I wanted to see if most here would agree that LIFO (reverse return) would be the best option for multiple water heaters, or is there a different set up y'all would prefer.
