A.O. Smith introduced its new high-efficiency modulating VF boiler, which replaces the company’s Legend Series, effective April 23. The VF boiler is a totally new design that provides up to 88 percent thermal efficiency while maintaining low NOx emissions that are better for our environment. The vertical tube design allows for a large heat transfer area, maximizing efficiency while maintaining the small footprint ideal for retrofit applications and multiple boiler installations. The VF boiler can be direct vented for up to 70 equivalent feet of intake and exhaust piping, and it can also be sidewall vented for up to 100 equivalent feet when combustion air is taken from the boiler room.
