Light Duty Commercial Electric Water Heater


A long lasting, trouble-free water heater

The Hubbell Endurance E water heater incorporates a number of features, not found in other conventional heaters, that make it better suited to resist the highly corrosive effects of hot water. The heart of a Hubbell water heater is a superior storage vessel which utilizes a specially formulated HydraStone cement lining, solid copper-silicon threaded tank openings and a built-in heat trap device, all of which ensure a longer lasting and energy efficient water heater.
