Why does my gas water heater not stay hot?
Is your gas water heater not hot enough? If you find yourself in this situation, there are usually three common culprits: a broken dip tube, a buildup of sediment in your tank or a malfunctioning heating system.
How to troubleshoot a gas hot water heater?
Gas hot water heater troubleshooting usually leads you to the thermocouple. Go to the article ‘Gas Water Heater Thermocouple Issues’ for information on this common repair. The other less common problem would be the gas valve. A bad gas valve will not allow any gas to go to the burner or pilot light.
How does a gas hot water heater work?
Gas water heaters work because of convection, which essentially means hot water and air rises. When the dip tube pushes cold water to the bottom of the tank, the heating element begins to heat up that cold water. As it warms, it rises to the top of the tank, where it is pulled out by your heat-out pipe.
Can You flush a gas water heater with cold water?
If you have a large amount of sediment, you may need to drain the tank completely and flush the tank with cold water to remove all the sediment. To flush the tank, turn on the cold water spigot to allow cold water to enter the tank.
How long does it take to drain a gas water heater?
Depending on the size of your water tank, this can take 2-3 hours. Enter your home and turn on the hot water to drain the pipes. Turn the hot water on in two points, such as a sink and a tub. That will prevent a vacuum from forming in the water lines while you are draining the water tank.

What do you need to know about gas tank water heaters?
Before purchasing a high-efficiency gas tank water heater, you should understand what type of fuel you currently have in your home, how much hot water you use on a daily basis, and where your current water heater is installed. A condensing water heater generally uses a different type of venting and requires a floor drain to dispose of condensate.
