    Well every inch of elevation reduces the pressure of the water, not to mention any additional restrictions that might be added upon the conversion, so I would not be surprised that you might notice a reduction in water out the back. I would bet that the t-stat will more then compensate for it and will most likely be nothing to worry about.
