Water heaters are essential appliances in every home. They provide hot water to wash dishes, clean clothes, or even take a shower. In addition to providing hot water, they also save energy, reduce carbon emissions, and improve indoor air quality.

There are two types of water heaters: electric and gas. Electric water heaters run off electricity from the power grid. Gas water heaters burn natural gas.

Pilot valves are installed in the main line of the water supply pipe. When the temperature reaches a certain level, the pilot valve opens and allows cold water into the system. This helps to prevent damage to pipes and appliances.
