View specifications

  • Heat Exchanger-Single-Wall 1½" O.D. glass coated (Ultonium®) carbon steel coil. The coil has a heat transfer area of 14.2 sq. ft. and a stored water volume of 2.7 Gal. Maximum supply temperature from the boiler must not exceed 250°F.
  • Factory Installed Sparge Tube System-Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
  • Ultonium® Lining-Niles Steel Tank water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The Niles Steel Tank high silica Ultonium® lining provides a tough interior surface for our hot water tanks.
  • Immersed Adjustable Honeywell Aquastat-Fast acting immersion aquastat for automatic temperature control (adjustable from 80°F to 160°F).
  • Supply and Return Connections-1" NPT female connections are located on the front for both the boiler collector supply and return.
  • 2" Non-CFC Foam Insulation-Covers the side and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Potable Water Connections-3/4" NPT factory installed true dielectric fittings extend water heater life and eases installation.
  • Three Protective Aluminum Anode Rods-Provide added protection against corrosion for long trouble-free service.
  • Steel Tank-Heavy gauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining.
  • T&P Relief Valve-Included.
  • Brass Drain Valve.
  • I=B=R Certified-These water heaters are rated by the Institute of Boiler and Radiation Manufacturers (I=B=R) to provide accurate performance data within the standards of the certification. The I=B=R rating is issued by the Hydronics Institute Division of GAMA and provide a recognized standard for proper comparison of hydronic appliances.
