HOT WATER SUPPLY SYSTEM USING GENESIS
®
BOILERS
With Ac-U-Temp, A. O. Smith makes it easy as possible to install a complete packaged hot water
supply system, combining 84% efficient Genesis
®
boilers with storage tanks up to 1,000 gallons.
Each Ac-U-Temp system is custom-made to your specifications for each application and shipped
fully assembled, pre-piped and pre-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-Temp system.
