The Hubbell J Model is the longest lasting booster heater available because it utilizes a heavy duty ASME Section VIII designed, constructed and stamped all stainless steel tank which does 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.
Hubbell did not just improve tank design - Our booster is 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.
