Basic Functioning of a Water Heater

A water heater is a device that warms and stores water in a building or residence. The water within a tank is heated using electricity, gas, or another fuel. The water will stay hot in the tank until it is needed because of insulation.

A dip tube ensures that cold water enters the tank when a hot water tap is switched on, ensuring that the cold water sinks to the bottom. The heating element, which is powered by gas or electricity, raises the temperature of the water coming out of boiler to the required level. A safety valve releases excess pressure to stop the tank from bursting, and a thermostat regulates the temperature of the water.

The hot water is then sent through a conduit to the faucet. When the tap is closed, the flow of both cold and hot water is cut off. It is an excellent idea to have a backup plan in place in case something goes wrong.

Tips to Prevent Water Heater Issues
