how long does it take for hot water after lighting water tank its gas?
The question doesn't contain enough information. When you open the hot water facet, does the water come out hot, but cools quickly? If so then you probably need to replace the dip tube. The dip tube insures that the cold water is injected at the bottom of the tank as the hot water is with drawn from the top of the tank. Dip tubes are mounted in the cold water input side at the top of the tank. some times dip tubes break off at the top so when you start drawing hot water from the top of the tank the cold water is injected into the top of the tank and this makes your hot water cool quickly. The water will come out hot, but will cool quickly. Normally when the cold water is injected into the bottom of the tank (through the dip tube) it will displace the entire tank full/column of hot water out through the top of the tank before the cold water gets to the top.
No, a hot water tank heats water by itself.
