COMMERCIAL WATER HEATING
When a Chili’s Grill & Bar Restaurant in Raynham, MA experienced many store
closures due to failure of their 199,999 BTU, 100 gallon commercial tank unit,
they knew they needed to make a switch to a better alternative. Not only were
they losing business for one or more days with the repairs/replacement to their
water heater, but they also had to incur the expensive repair/replacement
costs. To find a permanent
solution, the Chili’s restaurant
contacted Facilities Resource
Group, who performed a
Chili’s Grill & Bar Restaurant (Raynham, MA) complete testing and assessment
of the site and came up with the Noritz Tankless Water Heater Solution that would fit the Chili’s
restaurant’s needs. The Noritz tankless water heater would offer durability and redundancy,
which the previous commercial tank was unable to provide. Noritz’s high grade, quality
engineered tankless water heaters are built to last and deliver long term performance. Should
any one of the Noritz units in a multi-system setup need any service or repairs, this could be
done without compromising the business. The other units online would continue to provide Before: 199,999 BTU, 100 gal.

Why Chili’s Chose Noritz:

Another advantage of the

• Lower Repair Costs
and heat water using only the
energy necessary, saving the Chili’s restaurant on their water heating costs. Under the
direction of Facilities Resource Group, the recirculation pump line was redone, maximizing
the Noritz systems efficiency and adding even more energy savings. Previously with the
commercial tank water heater installed, the pump would always be on, even during closed

hours when no hot water was being used. Since making the switch to a Facilities Resource
Group system design using Noritz tankless water heaters, the pump can now be set to shut side wall, clearing up space and
making the mechanical room more
off completely during closed hours. To actually show the difference in efficiency, Facilities
