Hot Water Supply Systems

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.

Features

Simplifies Installation

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

Eliminates Costly Field Errors

§These complete hot water systems are factoryengineered and assembled to assure proper pipe, pump and wiring sizing

§Systems are pre-piped and wired to guarantee maximum system efficiency

FactorY Tested

§Each Ac-U-Temp system is hydrostatic and fire tested before shipping from the factory

Ac-U-Temp Storage Tanks

§Each Ac-U-Temp storage tank is especially designed with tank opening locations that provide maximum tank draw efficiency and eliminate any unnecessary piping

and connections

§Standard Ac-U-Temp tanks are factory jacketed and insulated (Bare tanks to be insulated by others are also available.)

§The Ac-U-Tanks are 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)

§Many combinations of heaters and tanks are available. Consult your local A. O. Smith Representative for factory assistance.

Multi-Unit Systems

§High recovery systems that can meet any hot water demand

§Systems can be designed to provide 50 to 100% back-up

§Heaters can be on & off fired, or sequenced to meet changing system demands

§Sequenced multi-unit systems 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 operation

§Both, water-to-water, or steam-to-water heat exchangers are available in both single wall and double wall

§Complete control packages can be factory installed for hook-up and run capability

§Electric Back-up - Heavy-duty electric water heater elements and controls can be specified for up to 3,000 KW; 100% electric back-up

§Providescurtailmentshot water even during natural gas
