Indirect dhw??

Cyclist77 · March 11

We have a Weil-McClain I direct dhw tank. This along with the Weil-McClain CGa3 were installed in November. One thing I seem to be noticing is that it calls for the boiler to respond when not all that much hot water is used. I hope I am being clear.

Advice?

Thanks!

If it is this tank, I'm not thrilled about the control location at the bottom. As soon as you open a faucet cold enters the tank and hits that control turning on the boiler. looks like cold water in #6, blasts right at the thermostat #2, across the tank?

More commonly the sensor is mid point on the tank so you draw 10 gallons or more before the sensor sees cold water and turns on. The HTP example.

The sensor down low starts the boiler sooner for recovery, but may cause the quick cycles you see.

Where is your sensor and control?
