Mouse got into the hot water heater thru the exhaust, now we are told that the fan bearings are bad - we have hot water, but when at the shower, it cannot produce enough hot water to keep up with the amount of water, thus a cold shower! Does this should right?

Theoretically possible-----a mouse can get in, but most exhaust fan bearings are permanently sealed and are expected to run perfect for their designed life, without any need for lubrication---if a mouse got in, i can only assume that it was chewed up (or it's **** /urine) and was pulled into the motor/bearing shaft and caused some slow in revolutions due to animal parts grinding in the smooth bearings ---it could happen--it depends on how the bearings are sealed around the exhaust motor shaft....orrr, the mouse was killed by the spinning exhaust fan blade, and then "pasted" to the fan blades(ironically called a squirrel cage) and this caused extra weight and an unbalanced exhaust fan which would rapidly cause wear and burnout of bearings due to tremendous speed of exhaust fan---i have seen many a dead rodent inside "squirrel cages" (furnace and water heater exhaust fans and their housings)...in fact i chose to even scrape some of them out for refurbishment!
