Does anyone have experience with the AO Smith Vertex water heater? My plumbing supply house only carries AO Smith and I am trying to decide between the Vertex and a standard powervent unit. There is about a $450 diffence with the Vertex being around $1450.
I will be using it for my DHW and radiant heating (isolated thru a heat exchanger).
Here is some info on the Vertex for those who have not heard about it. http://www.hotwater.com/lit/spec/res...RG-SS01306.pdf
