A water heater is a device that heats water for domestic or commercial use. It is typically a large tank that stores hot water, which is then circulated to faucets and appliances throughout the home. Water heaters can be powered by gas, electricity, or solar energy.
The most common type of water heater is a tank-type water heater. Tank-type water heaters have a large insulated tank that holds hot water. When a hot water tap is turned on, cold water enters the tank at the bottom and displaces the hot water, which is then circulated to the tap. As the hot water is used, the tank refills with cold water and the heating element turns on to heat the water up again.
Another type of water heater is a tankless water heater. Tankless water heaters do not have a storage tank. Instead, they heat water as it is needed. This type of water heater is more efficient than a tank-type water heater, but it is also more expensive to purchase and install.
Water heaters are an important part of any home. They provide hot water for bathing, washing dishes, and laundry. Water heaters can also be used to heat water for pools and spas.
