My point is that the outlet and the vacuum are both allowed and are common. If you must raise the electric water heater to get out of the "zone" then logic would say these other items would have to get out of that same zone. 
That is the logic that some AHJ's use to require outlets at least 18" above a residential garage floor using general intent provisions, but I think the logic is flawed.
I don't think we are talking about explosions, but fires starting. I understand investigations have shown that appliances (oil, gas, and electric) have been the cause of fires starting in garages, and so restrictions were added to the model codes. Apparently outlets do not pose the same risk ... perhaps because people are generally using them at the time, and can see if something ignites.

Question:
My 40 gallon water heater is located in my garage.
It measures 53" from the floor to the top of the tank, the hot water control (ignition source) measures 25" from the floor. Would you write it up, even if it exceeds the 18" rule?

Since the 18" rule is a minimum ... that WH exceeds the minimum requirement, and therefore meets the model code provisions ... as a guide ...  .
P.S. A "receptacle" is also not an "appliance", which is what that 18" rule applies to.

25" from the floor to the bottom element? That is strange. That places the element at about the halfway point in the tank, and I've never seen that before.
When you said "the hot water control" do you mean a temperature adjustment control? Or the element? I've seen a couple of electric water heaters which had a temperature control knob (lower thermostat setting) sticking through to the outside of the tank - I think they were Sears tanks. However, the element will be below that, where the bottom cover is.
