- Incoloy stainless steel lower element lasts longer than a standard copper element
- Helps reduce lime and sediment build up, maximizes hot water output, made from long-lasting Pex cross linked polymer
- Eco friendly non-CFC foam insulation, heat traps and other features combine to yield a higher energy factor that maximizes savings on operating costs
- Our anode rods have a stainless steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods
- Blue diamond glass coating provides superior corrosion resistance compared to industry standard glass lining
- Our residential water heaters have a solid brass, tamper-resistant, enhanced flow, ball-type, drain valve
- Uses a standard female hose fitting that allows for fast and easy draining during maintenance
- Designed for easy operation, this valve includes an integral screwdriver slot that features a quarter-turn (open/close) radius, which not only permits full straight through water flow but also a quick and positive shut-off
