Hot Water Supply Systems

The "TOTAL SYSTEM" Concept- We have taken our highly efficient equipment and created a convenient package; a complete domestic hot water system.

Simplifies Installation- The installer simply connects the flue, gas, electric supply, cold watermake-up,and hot water supply (Building return loops connect to cold watermake-up.)

Eliminates Costly Field Errors- These complete hot water systems are factory-engineered and assembled to assure proper pipe, pump and wiring sizing. Systems are pre-piped and wired to guarantee maximum system efficiency.

Factory Tested- EachAc-U-Tempsystem is hydrostatic and fire tested before shipping from the factory.

Ac-U-Temp Storage Tanks- EachAc-U-Tempstorage tank is especially designed with tank opening locations, that provide maximum tank draw efficiency and eliminate any unnecessary piping and connections. StandardAc-U-Temptanks are factory jacketed and insulated (Bare tanks to be insulated by others are also available.) TheAc-U-Tanksare factory standard with the same superior glass lining that has set new standards for the tank industry. Standard tank capacities range from 80 gallons to 1,000 gallons (Custom tanks to 10,000 gallons are available).

Other Features

ASME Temperatures and Pressure Relief Valve 125# - Tank Temperature SensorTank ThermometerIsolation Valves (Reliable Ball Valves) - Superior I-BeamSkid - 125 psi Tank Construction - CI Bronze Fitted Pump.

Options- All Bronze Circulating Pump - Sequencing Control Panel (ForMulti-Boilersystems) - 150 and 160 psi Tank Construction - 11" x 15" ManholesCement and Epoxy Tanks Linings.

Custom Ac-U-TempSystems-All Ac-U-Temp Systems are built to order, and can be precisely designed to specifically meet your specifications. Many combinations of boilers and tanks are available. Consult your local A.O. Smith Representative for factory assistance.

Multi-Boiler SystemS- High recovery systems that can meet any hot water demand. Systems can be designed to provide 50 to 100%back-up.Boilers can be on & off fired, or sequenced to meet changing system demands. Sequencedmulti-boilersystems that employ relatively small storage tanks are ideal for applications with constant, yet fluctuating hot water demands.

Multi-Tank Systems- For applications with low ceiling heights or unique installation challenges.

Optional Dual Energy Source Capability - Ac-U-Temp storage tanks can be specified with heat exchangers; allows winter/ summer heating boiler operation. Both, water to water, or steam to water exchangers are available in both single wall and double wall. Complete control packages can be factory installed for hookup and run capability.

Electric Back-up - Heavy - duty electric water heater elements and controls can be specified for up to 3,000 KW; 100% electricback-up.Provides hot water even during natural gas curtailments.

LIMITED WARRANTY OUTLINE

If the heat exchanger modules should fail within 5 years, under the terms of the warranty, A.O. Smith will furnish a replacement part; installation, labor, handling and local delivery extra. If the tank should leak any time during the first 5 years, under terms of the warranty, A.O. Smith will repair or replace the tank; installation, labor , handling and local delivery extra. THIS OUTLINE IS NOT THE WARRANTY. For complete information, consult the boiler and tank warranties or information, consult the boiler and tank warranties or A.O Smith Water Products Company.
