It sounds like air is in the water heater. It happens when your city water is shut down for repair sometimes and you get air in your pipes when the water flow is continued. You didn't open the valve enough or you may not have an air trap pipe.

Hot water is simply water that is hot, regardless of where it comes from.
yes it is. depending on your tests, though. i tested it, and it turned out to be tap water. test it for yourself! :)

Instantanoous multipoint water heaters : These provide hot water to multiple taps or appliances at the same time. when the hot tap is turned on, a powerful gas burner in the heater ignites. The incoming cold water is heated as it flows through a large heat exchanger located above the gas burner. The heat ecchanger heats up a large volume of water very rapidly. They do not supply hot water to a cental heating system. Combination boiler : These provide hot water to the central heating system and instantanious hot water to the tap. when the hot water tap is turned on all the heat is diverted to the heat exchanger to give a rapid responce. hope this is of some use. austin mod 6

It is mainly insulating of the hot water pipe that will save you water and money. You know how you turn on the hot water tap and let it run until the hot water comes out. This water is wasted just going down the drain. When the pipe is insulated the water that is left in the pipe when the tap is turned off will not cool off as fast. Then when the tap is turned on again, it won't take as long for the hot water to get to a temperature that you want. Insulating the cold water pipe also has an advantage, it stops condensation from dripping from the pipe.I completely agree with the answer given. Water conservation is very important as drinking water shortage is a growing problem in many parts of the world. Given below are some simple and inexpensive tips to save water. Check them out.
