i want to replace a bosch gws 715 es water heater with a bosch
940es. all the lines – water gas and vents are in the same
place on both heaters. anybody have any experience in doing this?
The two heaters use the same frame but the 715 is non-condensing while the 940 is a condensing machine.
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?
