Understanding Water Heaters
Before we dive into the main topic, it’s essential to understand how water heaters work. A water heater is a tank that stores water and heats it using electricity or gas. The most common types of water heaters are:
- Conventional tank-style water heaters
- Tankless water heaters
- Heat pump water heaters
- Solar water heaters
Conventional tank-style water heaters are the most common type and use a gas burner or electric heating elements to heat the water. Tankless water heaters, on the other hand, heat water only when needed, and heat pump water heaters use heat from the air to heat the water. Solar water heaters use solar panels to heat the water.
How Water Heaters Work
A conventional tank-style water heater works by using a gas burner or electric heating elements to heat the water in the tank. The tank is insulated to keep the water hot, and a thermostat regulates the temperature. When you turn on the faucet, hot water flows out of the tank, and cold water flows in to replace it.
The pilot light is a small flame that burns constantly to ignite the gas burner when the thermostat calls for heat. The pilot light is usually located at the bottom of the tank and is fueled by a small amount of gas.
The Importance of the Pilot Light
The pilot light is an essential component of a gas water heater. It provides a constant source of ignition for the gas burner, allowing the water heater to heat the water efficiently. Without the pilot light, the water heater would not be able to heat the water, and you would not have hot water.
However, the pilot light can also be a source of energy consumption. A pilot light can consume up to 20% of the energy used by the water heater, which can increase your energy bills.

Remember, it’s essential to weigh the pros and cons and consider your specific needs before deciding whether to keep the water heater flame always on.
Should the water heater flame always be on?
The water heater flame should not always be on. It is designed to turn on and off as needed to heat the water in the tank. When the temperature of the water in the tank drops below a certain point, the flame will turn on to heat the water back up to the set temperature. Once the water has reached the desired temperature, the flame will turn off.
This process is controlled by a thermostat that monitors the temperature of the water in the tank. The thermostat is usually set to a specific temperature, and the flame will turn on and off as needed to maintain that temperature. If the flame is always on, it could be a sign of a problem with the thermostat or the heating element.
What are the benefits of having a water heater flame that turns on and off?
Having a water heater flame that turns on and off as needed can help to save energy and reduce your utility bills. When the flame is only on when it needs to be, it uses less energy than if it were always on. This can also help to extend the life of the water heater by reducing the amount of wear and tear on the heating element.
Additionally, a water heater flame that turns on and off can help to ensure that the water in the tank is always at a safe temperature. If the flame were always on, the water could become too hot, which could be a safety hazard. By turning the flame on and off as needed, the thermostat can help to maintain a safe and consistent temperature.
What are some common problems that can cause the water heater flame to stay on?
One common problem that can cause the water heater flame to stay on is a faulty thermostat. If the thermostat is not working properly, it may not be able to turn the flame off, even when the water in the tank has reached the desired temperature. Another common problem is a malfunctioning temperature and pressure relief valve. This valve is designed to release excess pressure and temperature in the tank, but if it becomes stuck or faulty, it can cause the flame to stay on.
Other common problems that can cause the water heater flame to stay on include a faulty heating element, a malfunctioning gas valve, or a problem with the electrical connections. In some cases, the problem may be with the tank itself, such as a leak or a buildup of sediment. If you notice that your water heater flame is staying on, it’s a good idea to have it checked by a professional to determine the cause of the problem.
How can I tell if my water heater flame is working properly?
