Questions about this item

How hot will the water actually get at the tap when the heater is set to its maximum?

The maximum delivered temperature is 160 degrees F, so water leaving the unit can reach that level under normal operation.

What electrical supply does the 277 V rating require in practice?

It operates on 277 V AC single-phase power and draws 20 A, so a dedicated circuit at that voltage is needed.

Will the 6.25 in height and 2.75 in depth fit under a standard bathroom sink cabinet?

The unit measures 6.25 in high, 9.63 in wide and 2.75 in deep, making it compact enough for most undersink installations.
