The more hot water you need, the more you need a Vertex water heater.
Through an inspired blend of innovation, efficiency and years of
industry expertise, A. O. Smith has created a family of state-of-the-
art products that provide a long-lasting supply of hot water during
those times when everyone in your home needs it most. Vertex™ power-
vent and power direct-vent gas water heaters take high-demand homes to
the pinnacle of hot water availability. Vertex offers up to 96%
thermal efficiency with performance that rivals much larger water
heaters. With its fully-condensing design, Vertex delivers “continuous
hot water” — shower after shower, hour after hour. Yet it’s easy to
install, with dimensions and installation requirements comparable to
standard power-vent and power direct-vent units.

and ransley you claim having a tankless but now claim you have vertex
high BTU unit. which if either do you really have?

The vertex does not have an EF of 96, its near 80 or even less, spend
some time and fine EF on a Vertex, AO doesnt want you to know it.
