The new VF Series Boiler from A. O. Smith provides up to 88% thermal efficiency by utilizing a vertical tube design.
new VF Series Boiler is yet another testament to the innovative tradition of A.
O. Smith. This boiler provides up to 88% thermal efficiency by utilizing a
vertical tube design-allowing a large heat transfer area while maintaining the
small footprint ideal for retrofit applications. The unit’s modulating capabilities with 4 to 1 turndown ratio
prevents energy-stealing short-cycling, smoother system operation and higher
overall system efficiencies.
