96% Efficiency – For Life.
With 96% thermal efficiency, the Lochinvar SHIELD
™
is one of
the most energy-saving “green” commercial water heaters on
the market. But what does that mean to you in terms of the
cost of running your business. It’s easy to understand if you
compare dollars and cents!
Standard Efficiency: 80%
From every dollar spent on energy…
80¢ actually heats water.
20¢ is lost through
exhaust gases.
Sustained thermal efficiency brings
years to your hot water systems.
Lochinvar innovation makes SHIELD different and better than other com-
mercial water heaters, simply because there are no flue tubes or other heat
exchanger components inside the tank. The advanced stainless steel SHIELD
heat exchanger is completely separate from the glass-lined tank.
This unique design eliminates the energy-robbing effects of lime scale build-
up on the heat transfer surfaces. SHIELD is 96% efficient, and designed to
stay that way throughout its life cycle!
The SHIELD Smart Control
™
System features temperature setback and a time
clock, so you can set schedules to reduce energy consumption when hot
water is not needed.
And unlike water heaters with noisy combustion systems, SHIELD is also
whisper quiet, so it will never disturb your guests or employees.
Compare SHIELD efficiency to compet-
itive water heaters over 5 years…
The estimated comparisons below show the effects of lime
scale buildup on thermal efficiency and yearly operating cost
for the 96% efficient SHIELD versus a standard 80% efficient
tank-type water heater.
Bottom line, because of its 96% efficiency and
immunity to lime scale, SHIELD will pay back the initial cost difference in
energy savings alone in just 1.43 years!
Comparison based on 200,000 Btu/hr units delivering 2,000 gallons of hot water per day, 365 days/year, at an 80°F temperature rise, with a natural gas rate of $1.58/therm.
High-Efficiency SHIELD: 96%
From every dollar spent on energy…
96¢ actually heats water.
Only 4¢ on the dollar is
lost through exhaust gases.
SHIELD saves you 16¢ on
every heating dollar you spend!
