Setting thermostat on water heater Wilton, CT

Water heaters are a crucial part of our daily lives, providing hot water for showers, laundry, and dishwashing. Understanding how they work can help you appreciate their role in providing comfort and convenience, as well as maintain them better. JNR Plumbing, trusted in water heater repair in Wilton, CT, explains how water heaters work below:

Heating Element

Water heaters rely on a heating element to warm up the water. In electric water heaters, this heating element consists of one or two coils that heat up when electricity is applied. As the water flows into the tank, the heating element warms it to the desired temperature. For gas water heaters, a burner is the source of heat. A gas flame is ignited underneath the tank, and the heat is transferred to the water through a heat exchanger. To keep the heating element of your unit in great condition, be sure to schedule routine water heater services.

The Thermostat

The thermostat is a crucial component of your water heater. It allows you to set and control the water temperature to suit your needs. Thermostats are typically located on the side of the tank for easy access. When the water temperature drops below the set level, the thermostat signals the heating element or burner to kick in and start heating the water. After water heater installation, we recommend testing the thermostat to determine if it is working properly.

The Dip Tube

The dip tube is a long tube that directs cold water to the bottom of the tank. As the heating element warms the water, hot water naturally rises to the top of the tank, ready for use. Without the dip tube, incoming cold water would mix with the heated water at the top, resulting in lukewarm water coming out of your faucets. That said, if you have a tankless water heater or a traditional heater with a water inlet at the bottom, there will be no dip tube on your unit.

Understanding how your water heater works is valuable not only for everyday use but also for troubleshooting any issues that may arise. With regular maintenance, you can keep your water heater running efficiently. If you encounter any problems, turn to JNR Plumbing for professional water heater replacement and repairs.
