Large Volume Electric Power Water Heaters

Built for outstanding performance and efficiency, our large-volume electric water heaters can offer you significant savings. With capacities of up to 2500 gallons, your first step is choosing the appropriate size for your application with our Rightspec® Sizing Guide.

  • Energy-Saving Performance – High-density closed cell foam insulation is used to meet the demanding ASHRAE 90.1b current standard for minimizing heat loss. This requirement, allowing a maximum 4 watts per square foot of tank surface energy loss, offers big savings and operating efficiency.

  • Magnetic Contactors with Immersion Thermostats – 120 volt control circuit with built in transformer. Elements are thermostatically controlled in 54kW (max) increments.
  • 12′′ x 16′′ manway on models 250 gallons and larger.
  • Low Watt Density Incoloy Elements – A smart choice for superior characteristics to copper-sheathed elements in rigorous water heating applications. This tough alloy successfully resists the effects of prolonged high operating temperatures, hard water, acids, corrosion and thermal shock. Their nominally higher initial cost is more than off-set by much longer life expediencies and reduced service and replacement costs. Incoloy elements are designed to “burn in air” to prevent failures caused by water void.
  • Internal Fusing – All elements and circuits are fused in 48-amp increments, providing complete electrical protection. Cartridge type fuses are rated at 200,000 ampere interrupting capacity.
  • Ultonium® Glass Lining with Microban® – Applied to the interior surface of the steel for superior protection against corrosion. Microban® antimicrobial technology helps prevent the growth of bacteria, mold and mildew on the surface of the tank lining.
  • Magnesium Anode Protection – Provides anodic protection against corrosion of the tank due to electrolysis.
  • Painted Steel Jacket – Coated on both sides and beautifully finished in durable finish with an attractive appearance.
  • Hinged Door with Key Lock – Quality requires full length hinged doors for ease of inspection and maintenance. Keyed door lock provides additional safety and security at no charge.
  • Digital Temperature Display – Easy to read digital temperature display.
  • Temperature and Pressure Relief Valve – Factory provided ASME rated relief valve protects against excessive temperature and/ or pressure build up within the tank.
  • Terminal Block Connections – Offers easy and safe wiring connections.
