i want to replace a bosch gws 715 es water heater with a bosch

Paul,

The two heaters use the same frame but the 715 is non-condensing while the 940 is a condensing machine.

Paul,

I stand corrected. the 940 as well as the 715 is the same machine. Both are non condensing machines. The 940 is a later version which incorporates an externally accessible inlet water filter screen. The 715 had the option for this externally accessible inlet water filter screen.
I must again ask the question, why do you want to “upgrade” to essentially the same heater?
Thanks,Bill
