COMMERCIAL ENERGY SAVER
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.
• Heat Exchanger—Single wall 1
1
⁄2"
glass coated steel.
• Factory Installed Sediment Reduction
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 at top
of tank.
• Three Protective Anode Rods—
Provides added protection against
corrosion for long trouble-free service.
• Glass Lined Tank—Laars Heating
Systems water heater tanks are
protected from the corrosive effects of
hot water by an exclusive ceramic
porcelain-like coating.
• Fully Automatic Controls—Immersed
Honeywell aquastat.
• Factory Installed Nipples—For longer
water heater life, easier installation.
• 2" Non-CFC foam insulation—Covers
the sides and top of tank to save
energy by retarding loss of heat.
• Supply and Return Connections—The
1" NPT female connections are
located on the front for both the boiler
supply and boiler return.
• Stand-by Heat Loss—Less than
1
⁄2°F
per hour.
• Brass Drain Valve.
• T&P Relief Valve Installed—All models
feature opening on side of tank.
• Five 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.
• One Year Limited Warranty on Parts.
