The Hubbell J Model line of electric booster heaters are the longest lasting boosters available because they utilize heavy duty ASME Section VIII designed, constructed and stamped all stainless steel tanks which do not require an internal tank lining. Other manufacturers use a non ASME steel tank with an internal lining that can easily erode in high temperature water and eventually leaves the bare steel tank exposed to the corrosive effects of water. Once this occurs, it is only a short time before the steel tank will begin to rust, leak and need replacement.
Our boosters are also equipped (as standard) with the advanced functionality of an electronic temperature controller to provide accurate, reliable, and energy efficient operation while simplifying service work. The Hubbell booster’s closed cell foam insulation also improves operating efficiency and reduces the cost of operation.
