I have a rather vexing issue with my hot water recirc loop. When the loop is on there isn’t enough hot water for more than an couple of showers. (50 gallon, Dual element electric). When the loop is off there is plenty of hot water after two showers and little if any decrease in temperature (125 degrees). Check valves are properly installed. Replaced both T-stats, dip tube and both elements have proper resistance and there is proper voltage to both elements. Heater is less than 2 years old. Pump is operating properly and pumping in the correct direction. When the recirc loop is on the overall temperature measures around 125 degrees. When the loop is off the overall temp is 130 degrees. (before someone comments on the temps—its high because I am “fiddling” with it). Also, the return of the loop goes to the cold at the top of the tank as opposed to the bottom of the tank, which as I understand it isn’t supposed to matter. Does anyone have any opinions as to what might be wrong?
It is easier to change direction than it is to forget where one has been.
