TOTAL HOT WATER SUPPLY SYSTEM USING VF™BOILERS
With Ac-U-Temp, A. O. Smith makes it as easy as possible to install a complete packaged hot
water supply system, combining high-efficiency VF™boilers with storage tanks up to 10,000
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.
