Does an indirect HW heater make sense with steam boiler?

I have a gas fired atmospheric HW heater that needs replacement. I know that indirect tanks are the most efficient during the heating season. But during the summer, my sense is that the large mass of boiler water in the WM SGO3 boiler will waste fuel and heat my house. My inclination is to stay with the 10-year gas HW heater.

Any thoughts?
