Electronic Gas Control

Intelligent control logic provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance.

Powered Anode Rod

Powered anodes are non-sacrificial, so they do not deplete over time. Additionally, they provide exceptional performance in all water conditions.

Brass Drain Valve

• Solid brass, tamper resistant, enhanced-flow, ball type, valve.

• Uses a standard female hose fitting that allows for fast and easy draining during maintenance.

• Screwdriver slot features a 1/4 turn radius, for straight-through water flow and a quick and positive shut off.

DynaClean™ Dip Tube

Helps reduce lime and sediment buildup, maximizes hot water output. Made from long-lasting PEX cross-linked polymer.

The high efficiency performance of the Effex® model is possible thanks to its patented air intake system. Air is pushed into the combustion chamber creating a pressurized environment. Due to this “turbo charge” effect, tighter baffling is incorporated in the flue design to slow down the hot gas as it travels through the water heater. This results in more heat transferred to the water and less energy wasted.

Rebate and incentive programs provide cash-back to consumers for the purchase of appliances that meet certain energy efficiency standards. Often, these standards are tied to the ENERGY STAR® certification program.

Cash for Appliances is designed to encourage the purchase of energy efficient appliances. Consumers who purchase ENERGY STAR® certified or CEE qualified appliances can receive cash rebates. Most states are offering rebates in the $50 to $250 range.
