ProMax residential electric water heaters has industry leading glass-lining with superior corrosion resistance. Provides quality hotel-like hot water unmatched by instant water heaters.


How It Works

Cold water enters the water heater through an internal “dip tube” which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection. This arrangement provides the hottest water for the given tank size.

The heater is equipped with upper and lower heating elements operating alternately to provide evenly distributed hot water in the water heater.

The heater is equipped with a double throw thermostat and lower thermostat with high limit protection that detect water temperature and turn on and off heating as needed.

The temperature and pressure relief valve is a safety device designed to open if the internal temperature or pressure of the tank exceeds certain limits. Water heaters should be large enough to provide adequate hot water even when temperatures are cold and household demand is at its peak.




Why Choose Our Product



  • Blue Diamond® Glass Coating

    Provides superior corrosion resistance compared to industry standard glass lining. Blue Diamond® Glass coating blend is formulated in the same lab that creates the protection for our industry-leading commercial product line.


  • Enhanced-Flow Brass Drain Valve

    Our residential water heaters have a solid brass, tamper-resistant, enhanced-flow, ball type, drain valve. They use a standard female hose fitting that allows for fast and easy draining during maintenance.

  • CSA Certified and ASME Rated T&P Relief Valve

    Protects the tank from excess pressure and temperature.

  • Diffuser Dip Tube

    PEX cross-linked polymer dip tube ensures incoming cold water enters at the bottom of the tank to prevent mixing with the hot water at the top.

    Helps reduce lime and sediment buildup while maximizing hot water output.

  • Coregard Sacrificial Anode Rod

    Aluminum anode rod with stainless steel core protects the tank from corrosion.

  • Tank Construction

    Heavy duty carbon steel tested at 300 psi and rated for 150 psi working pressure.

  • Heat Traps

    Equipped with factory installed heat traps on the inlet and outlet connections, improving energy efficiency.

  • Temperature Controls

    Surface mounted control thermostats with a temperature range from 43°C /110°F to maximum 71°C /160°F and hi-limit factory fixed setting at 83°C /180°F.

    Thermostats accurate to ± 2.5°C/ 5°F.

  • Code Compliance

    Complies with UL 174, SASO, GSO, PAI, and IEC 60335-2-21 certifications

    Meets US DOE and ASHRAE/IES 90.1 thermal efficiency and standby heat loss requirements.
