40 Gallon Laars-Stor Single-Wall Indirect Water Heater

Laars-Stor single wall commercial models incorporate a super-efficient heat exchanger. Made of 1.5" diameter carbon steel tubing and coated with a glass-lining, it has a total heat surface area of 27.2 square feet. The result is an exceptional first hour delivery and vast hot water reserves.

Features

• Heat Exchanger - Single-Wall 1-1/2" O.D. glass coated (Vitraglas®) 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 Sediment Reducing Inlet Tube - 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.
• Glass-lined Steel Tank - LAARS water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The high silica 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.
