Just to be clear, that 143F isn't the setpoint we are using.
That's how hot the Tee connection got during a run cycle.
(The Tee is where the HX loop enters the tank).
However, on the 16th, we turned up the setpoint to 130F. It was at 120F.
My wife really likes the 130F setting for hand washing dishes.
I'm thinking of moving it down to 120 or 125 during the cold months.. For efficiency.
