This is some basic information regarding how a storage water heater works so you will fully understand how this appliance manages to provide you with hot water every time you need it. To put it simply, the storage water heater works by transform energy into heat and then transfer it to the water.
The storage connected to the pipe that supplied cold water and delivers hot water out from the hot water pipe or you can say both of the like the system pipes that supply cold water enters the tank and hot water out the reservoir from the faucets. For detailed information, you can read below explanation.
Learn how a storage water heater works
Most of the standard water heater using natural gas as their energy and although electric and propane-fueled water heater can also be used, but natural gas is less expensive than other types of water heater like the two we are mentioned before. The electric water heater works exactly just the same with the gas water heater, and the difference is only no need to use a flue since it does not use gas.
Now, here is how the gas water heater works.
Just like the name suggested, the large tank on the heater works as the water storage which can hold between 20 to 80 gallons of water and the water will be heated for future use. The large volume is supplied through the cold water pipes right when you turn on the hot water tap. Water that holds right on the top of the tank will be removed through the hot water outlet, and then cold water will enter through the cold water inlet. Next, the gas burner which located right under the tank will start to heat the cold water that already replaced the displayed hot water from before.
On the best water heater, there is T&P relief valve or Temperature and Pressure relief valve which going to open when the heating temperature and pressure exceed safe levels. For your information, this valve needs to be tested regularly at the same time when the storage water heater tank is drained off, and this is a basic instruction from most of the manufacturer’s book.
And what about storage water heater that uses electric consumption to heat the water? Just like we already mentioned above, both natural gas and electric heaters have similar work. As for the electric one, there is an electrical cable that delivers the energy to the heating elements.
The good thing is an electric heater does not need vent unlike gas water heater because no combustion gas is created. Electric storage water heater typically works with one 5,500 watts element or two 4,500 watts elements with two separate thermostats which control both of the elements.
Proper maintenance and check-up are needed when you are installing a water heater at home. Especially for storage water heater, you should inspect the T&P relief valve every six months and flush out the water in the storage tank every three months.
