Things Are Heating Up: Gas Hot Water Heater
However, if that flow of hot water stopped it would be a different story. This is because having hot water is a convenience that not many people think about until it is no longer available.
Therefore, it may prove beneficial to have a little knowledge regarding a gas hot water heater. Specifically, how a gas hot water heater works and what are some things that could go wrong to make this type of heater inoperable.
How A Gas Hot Water Heater Works
A gas hot water heater is a modern day appliance that quietly functions in some remote place within the building. Specifically, the holding tank for the water comes in different sizes. Some of those different sizes could include a 10, 20, 30 or 40 gallon hot water tank. The tank is connected to two water lines. The one line leads into the tank and allows the flow of water. The other pipe leads away from the tank and carries the hot water throughout the facility.
In addition, this type of tank utilizes natural gas as the main energy source to heat up the water in the tank. The temperature of the hot water is controlled by a thermostat. When the water in the tank falls below the setting of the thermostat, the thermostat sends a signal to the gas burner to engage. This process then heats up the water in the tank until that temperature setting is reached. Once the temperature setting is reached the thermostat then sends another electrical signal to deactivate the gas burner.
When there is a demand for hot water within the facility the water then flows from the outgoing pipe to where the hot water is required. Once there is an outflow of hot water from the tank there's a corresponding flow of new water into the tank which then repeats the thermostat process of heating up the water to the required temperature.
Things That Could Go Wrong
As with any modern day convenience, there are a number of things that can go wrong with the natural gas water heater. One of the primary things that can cause a disruption in the hot water service is for the thermostat to malfunction.
Another item that could go wrong, but is less costly concerns the pilot light. The pilot light is that particular part of the natural gas water heater that constantly is aflame. Once the thermostat signals to the heating unit that the water needs to be heated the gas then begins to flow and the flame ignites the gas that flows throughout the burner system. Therefore, one of the less costlier things that can happen to stop the flow of hot water is for the pilot light to go out.
