Both are nice

I will have to build the three I need in the field. These prefabs are rated at 125psi maximum working pressure. The system they are going on is rated at 160psi heating hot water. I called Slant-Fin about the heat exchanger in their unit and it's rating and they gave me the answer of 125psi based on the pumped side. Taco also says 125 psi. I am not concerned about the pumped side pressure. The Combi Cat was looking real nice.
