Proven and reliable technology.
Ecient · 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.
