    • Advanced electronic control with LCD display for easy temperature adjustments and diagnostics
    • Ease of installation in replacement applications—can use existing venting connections

  • Ideal Replacement Model

    It’s a simple fact: the Effex is the most efficient and advanced conventional vent gas water heater on the market. This makes it an ideal choice for homeowners who want to replace their older, inefficient water heater without the hassle. This ENERGY STAR® qualified water heater also comes with another irresistible benefit: significant savings on utility bills.

  • High Efficiency, Big Savings

    Thanks to its low operating costs, the Effex can translate into significant savings for the homeowner over the course of its lifespan. In fact, with its .70 EF (compared to an average .53 EF of a ten-year-old gas product), the Effex can generate savings of up to 25% of annual operating cost.

  • Easy Installation

    Weary of hassles involved in a high efficiency water heater installation? With the Effex, there’s not much to worry about. For starters, it uses standard water and gas connections. It easily connects to existing B-vent on replacements, and it can be common vented. No wonder it is known as effortless.
