How Does The Hubbell Tankless Water Heater Work?
Hubbell has applied its 88 years of water heating experience and engineered a tankless electric water heater
that will provide many years of reliable service in your home. The cold water enters the unit and passes
through a flow meter and inlet thermistor which measure the precise flow rate and temperature of the
incoming water. The control system uses advanced logic with solid state switching devices to fully
modulate the power to the heating elements from 0-100% to provide the most accurate and consistent hot
water temperatures in the industry. As the water flows out of the unit a second thermistor makes any
necessary adjustments to ensure the Hubbell Tankless delivers accurate and consistent hot water. With
numerous control features including the ability to track kW hours consumed, operating cost and hot water
usage, the Hubbell Tankless allows the homeowner to maximize their savings and gain the most benefit from
their investment.

To solve for flow rate using a derated kW use the formula:
kW x 6.824 ÷ °FΔT = GPM
°FΔT = Change in Temperature (Hot - Cold)
If actual supply voltage is less than 240V, the kW
will be reduced, see de-rating factors below:
If 230 Volt multiply kW by 0.92
If 220 Volt multiply kW by 0.84
If 208 Volt multiply kW by 0.75

Efficient · Reliable · Energy Saving
The Hubbell Tankless Electric Water Heater is 99% efficient making it your best option for water heating.
Unlike storage tanks which are constantly working to maintain a tank full of 140°F water which is then
mixed with cold water when delivered to your fixture, the Hubbell Tankless unit heats water on demand
and precisely to your desired temperature (typically 105°F or 40°C). When you replace a tank water heater
with a Hubbell Tankless you eliminate 365 days of “stand by heat loss” and save energy by delivering hot
water more efficiently to the point of use. The end result is a savings of up to 40% on the water heating
portion of your utility bill.
Why Hubbell Tankless?
Gain valuable space when you replace your
conventional tank water heater with a Hubbell
ElectricTanklessWater Heater .
Enjoy unlimited hot water. Simply setThe Hubbell
ElectricTankless Heater to your comfort temperature
setting (typically 105°F or 40°C) and get consistent
and endless hot water.
No more inefficient mixing of cold water.
