Water from a hot water heater is not considered 'potable'. It should not
be used for cooking or drinking.
The reason is this. The danger zone for most bacteria is 40 degrees F to
140 degrees F. There are several harmful bacteria that can live in your
water heater, including legionella, if the temperature is maintained
below 140 degrees F.
The danger increases with less frequent use of the heater, meaning that
freshly treated water is not being introduced regularly to kill or knock
down these bacterial populations.
The bacteria can be introduced several ways; when installing any new
water line, breach in city main, native to well water, new water heater,
etc.

All,
I've got a Raritan heater. When I run my Yanmar 30GM the hot water
out of the tap is certainly cooler than I would get from my home water
heater. When used to make instant coffee the coffee can be drunk
right away without cooling.
How hot should the water get?
Do I need to flush the water heater?
