Hubbell Tankless Features
How It Works
The Hubbell tankless electric water heater contains high powered heating elements that heat water
only when there is demand for hot water. When hot water is needed, a built in ow sensor measures
the exact ow rate, and that data combined with temperature readings at the heater’s inlet and outlet
are processed by the electronic temperature controller. This data is continuously transmitted to the
temperature controller, which constantly calculates the precise amount of power (kW) needed to achieve
the desired temperature. A zero cross over ring signal is sent to the fast acting triacs in order to
modulate the heating elements to the precise level needed to meet demand. The Hubbell tankless heater
uses only as much power as is needed, while delivering accurate and consistent hot water temperature.
