Tankless Water Heaters by A.O. Smith
ProLine Electric tankless heaters are available in three sizes with 45 different models of 2.4-32kW and uniform energy factor up to 0.93. The units are available in a variety of voltage options: 120, 208, 240, and 277. All models have true Dry Fire Protection. The element will only turn on when the chamber is full of water, meaning plumbers and electricians have the freedom to work without fear of costly dry fires. All models also have scale-reduction technology, which reduces scale formation on the elements and on the chamber walls.
