depends what your cooking? pasta=good. boiled egg=bad. (to the above answer. Only in terms of saving cooking time but it does not come without a large trade off)....And its bad tradeoff, Heres why......... The insides of a hot water heater contain metals that can, and do corrode. Some of the pipes in your older homes that are not made of PVC may have lead soldering. Hot water will dissolve metals, especially lead, much quicker than cold water will. Not to mention that over the years of daily use of drawing gallons throughout the day in cycles causes the water from the local utility, with all of it's impurities to collect and precipitate in the bottom of the hot water heater. This is a prime breeding ground for bacteria. Perhaps they cannot survive in an environment where the water is around 140°, but as soon as the water cools down enough due to a power outage or extended leave (if you turn off your water heater), all the necessary nutrients are there in an 80 gallon soup. hope that deters you from cooking in hot tap water.

How hot does an electric stove element get?

Maximum temperature of water is the boil temperature. But the boil temperature depends on atmospheric pressure and on salt content of the water. The more atmospheric pressure the more temperature. Boil temperature in mountain can be 60 centigrade. At normal (not high) land it usually 100 centigrade. But, as I said, temperature also depends on salt content (amount of salt) in the water. The more salt the less boil temperature. This way to take high grade boil when you cooking put the salt in to the water at the last moment of cooking.
