Guys guys guys

WHAT IS THE FLOW RATE.

Like I said already, if the flow is partially blocked, it can run
forever and still be luke warm. BTUs delivered is by temp x volume.
If volume is low from a blockage it will never heat up.

If the flow rate has been tested I will drop this theory, but has it
been????
