I was told that i am being sent a replacement heater for my ae125. after looking at the unit i do not see how i am to remove the old heater. any help would be of great help.

Let's see, your original question said 'any help.' And you asked for a free answer. And wanted the free expert to go look up your model number at Bosch since you did not say gas or electric. And of course you did not say the brand either. And then complain that you got less than best answer. Let me say something. Your lax attention to detail tells me you should be wary of installing a tankless, which was the main point of the answer. Next time, post a clear and fully disclosed question, and then bring your checkbook and pay for interactive answer from fixya, so experts don't have to guess at your situation, and you get satisfaction of helping the economy.
