Is it possible that you and the dealer are measuring the hot water from two different points?
If the water in the heater is hot, and they are measuring it directly from the heater, via the pressure relief valve (see pic)................and you are measuring it from the inside taps, where it may be mixing in with cold water somehow (via a bad bypass valve, indoor/outdoor shower wands left in the off position while the knobs are in the on position).......then it's possible that the dealer is getting hot water and you are getting no so hot water.
Have you checked the water temp directly from the pressure relief valve?
If the water from the heater direct is hot, but not from the taps....then that let's you know what/where the problem may be.
