That's how hot the Tee connection got during a run cycle.

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.  |
Based upon your reports, apparently the A7 is capable of supplying normal residential DHW requirements.
However, in the winter cold season my DHWH, thru a HX, also supplies my in floor radiant system, a substantially greater demand. During this short cold period my thought is to use the propane fired DHWH as a low set point pre heater and the A7 as the secondary top off heater. Relative set points to be determined.
