TOTAL HOT WATER SUPPLY SYSTEM USING VFBOILERS

VWT-1000

 

 

With Ac-U-Temp,A. O. Smith makes it as easy as possible to install a complete packaged hot water supply system, combininghigh-efficiencyVFboilers with storage tanks up to 10,000 gallons. EachAc-U-Tempsystem iscustom-madeto your specifications for each application and shipped fully assembled,pre-pipedandpre-wired.All the installer has to do is make the flue, gas, electrical and water connections, so installations are easy.

Consult your A. O. Smith representative for more information on the wide range of available boiler/storage tank combinations using the Ac-U-Tempsystem.

VF MODULATING BOILERS

UP TO 88% THERMAL EFFICIENCY

A. O. Smith’s most efficient hot water supply boilers

Available inputs: 500,000, 750,000, 1,000,000 BTUs

Flexible conventional-ventorsealed-combustiondirect-ventoptions

For complete information on VF Hot Water Supply Boilers, consult VF Specification Sheet

GLASS-LINEDSTORAGE TANKS

Standard capacities up to 1,000 gallons

Custom tanks available up to 10,000 gallons

Standard tanks are factory jacketed and insulated – bare uninsulated tanks also available

Optional cement or epoxy-linedtanks available

For complete information on standard and optional tanks, consult tank Specification Sheet

MULTIPLE BOILER SYSTEMS

Ac-U-Tempsystems can be designed with multiple boilers to provide 50% to 100%back-up

Multi-boilersystems can be sequenced to meet changing system demands

Sequenced multi-boilersystems with small storage tanks are ideal for applications with relatively constant hot water demands

Optional sequenced control panel available

MULTIPLE TANK SYSTEMS

Ac-U-Tempsystems can be designed with multiple tanks for applications with low ceiling heights or other unique installation challenges
