Water heaters are devices that heat water, usually using natural gas or electricity. There are many types of hot water heaters, including the tank-style, which stores heated water, and the tankless, which automatically heats up water as needed. These heaters can run on several fuels, such as natural gas, propane, and electricity.
Tank-style water heaters are available in several models and configurations. Typical features include a metal tank and a glass-lined interior. This design helps prevent rusting. In addition, these models offer a drain valve for easy emptying. However, in some cases, the tank may fill up with sediment. For this reason, it is recommended that homeowners have the tank cleaned annually. The sediment can build up in the tank, preventing it from working efficiently. It is also a good idea to have your water heater inspected and serviced periodically by the plumbers in casa grande professional.
Hot water heaters are made from heavy metal and are covered with an insulating material to help reduce standby losses. They also feature a thermostat to keep the water warm. The temperature ranges between 120 and 140 degrees Fahrenheit, and most manufacturers recommend setting the temperature between these levels. A high temperature can cause the water to run out of hot water fast.
A traditional tank-style gas water heater consists of a pressure-tested water storage tank, a hollow exhaust flue, and a gas burner. A gas regulator assembly is installed on the side of the unit. The assembly includes a thermostat and a pilot light. When the tank is full, the burner is ignited.
The temperature and pressure-relief valve is a key safety feature of a water heater. If the heater becomes too hot or too cold, the valve releases excess pressure and relieves the tank. As the tank reaches a certain temperature, it releases water into an overflow pipe.
Hot water heaters can be a very compact appliance. Some of the smaller, less expensive units are designed with a decorative outer shell. Others have a small amount of exposed steel.
Many newer water heaters feature a thermocouple, a small valve that is used to convert the heat to an electrical impulse. It is also known as a flame sensor. During installation, the heater can be fitted with a heat trap to prevent the rise of hot water up the supply pipe.
In a tank-style water heater, the drain valve is located near the bottom of the exterior housing. When the water is full, this valve allows for easy emptying of the tank.
When purchasing a water heater, look for models that have an Energy Star rating. Higher numbers indicate more efficient units. You will save money in the long run. To ensure that you purchase a model that is best suited for your home, you can ask a plumber to order a model for you. Home improvement experts also recommend that you have a tank-style water heater inspected at least once a year. You can find more information here on water heating services.
Most water heaters are made to last for about 60 years. Several factors can shorten the life of a heater, though. Typically, internal corrosion is the leading cause. Having the drain valve removed and drained periodically is a good way to reduce the risk of premature failure.
