The invention discloses a condensing gas water heater, a condensing heat exchanger as well as heat exchanger plates. The condensing heat exchanger comprises: a housing and at least one heat exchanger plate disposed in the housing; the heat exchanger plate comprises a first metal board and a second metal board butting each other, wherein a surface of the first metal board and a surface of the second metal board which butt each other are butting surfaces, and two outer surfaces opposite to the butting surfaces are a first surface and a second surface, respectively; at least one of the first metal board and the second metal board is formed with a convex flow guide portion along a direction away from the butting surface; the first metal board and the second metal board form a fluid passage via the flow guide portion.
