A. O. Smith has added depth to its diverse product portfolio with the introduction of the ProLine Electric Tankless family for commercial, residential and point-of-use applications. The ProLine Electric Tankless is available in three sizes, with 45 different models ranging from 2.4kW to 32kW and Uniform Energy Factor up to 0.93. The units are available in a variety of voltage options: 120V, 208V, 240V, and 277V. The product line is equipped with innovative features and benefits previously unavailable in the electric tankless market. With built-in Dry Fire Protection and Scale Reduction Technology that helps to reduce failures and service requirements, the single-chamber design is compact enough to be mounted under a sink, in a remote bathroom or other hard-to-plumb area.
