• Factory installed waterway fittings - for longer water heater life. Easier installation.
• Fully automated controls - Fast acting surface-mount thermostat for automatic temperature control. Factory installed sensitive manual reset energy cut-off for safety to prevent overheating.
• Ultonium™ Lining - NST tanks are protected from corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The NST high silica Ultonium™ lining provides a tough interior surface for our hot water tanks.
• Protective magnesium anode rod - provides added protection against corrosion for long trouble-free service.
• Factory installed turbomix fill pipe - cold inlet sediment reducing device. Helps to minimize sediment build up in the tank. Increases first hour delivery of hot water while minimizing temperature build up at top of tank.
• Stand-by heat loss - less than 1/2°F per hour.
• Heat exchanger - dielectrically isolated, double wall type consisting of a highly conductive material with a, NSF approved cross linked polyethylene (PEX) coating. Also, incorporates two monofilament channels between the walls for leak detection purposes. Leak detection hole is located at top of unit on both heat exchanger connections.
• Brass drain valve.
• T&P relief valve included - all models feature top connection.
• Ten year limited warranty on steel tank and heat exchanger - heavy gauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining.
• 2" Non-CFC foam insulation - covers the sides and top of tank to save energy by retarding loss of heat. Also increases jacket rigidity.
• Six year limited warranty on parts.
