Smith has created a state-of-the-art family of Vertex™ products that provide a long-lasting supply of hot water. They are easy to install, with dimensions and installation requirements comparable to standard power-vent and power direct-vent units.

    ProMax®

    The ProMax® family of gas water heaters offers a wide range of water heating solutions. The high efficiency, side loop venting, Ultra-Low NOx and high recovery models are ideal for families with high demand for hot water.

    Effex®

    It's a simple fact: our Effex® product line is the most efficient and advanced line of conventional vent gas water heaters on the market. This makes it an ideal choice for the homeowner who wants to replace an older, inefficient water heater without the hassle.

    Conservationist®

    The line of Conservationist® gas water heaters offers maximum energy savings and reliability. Their environmentally friendly Green Choice® gas burners reduce NOx emissions by 33% compared to standard burners and the Blue Diamond® glass coating provides superior corrosion resistance compared to industry-standard glass lining.
