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.
