Flo-Direct Water Heater
Typical System
Page 3 of 45
Flo-Direct water heaters are highly efficient, low maintenance systems.
Complete thermal exchange technology means no fuel is used for warm-
up or idle time and no energy is lost through conversion or exchange.
Without internal moving parts, there is very little to maintain.
Water conditioning is not required.
Flo-Direct systems are highly customizable at both a system
and component level.
