More about Tankless Water Heaters

Although the first tankless water heater was used in Europe, today, it is widely used in almost every part of the globe. Such a heating unit heats up water almost instantaneously without the need to store water in a storage tank. It is good to know that tankless water heaters work only when you need hot water. As the tap for the cold water is turned on, it rushes through a pipe and enters the heater. There is a special device in the main unit of the heater, which is known as the heat exchanger. As cold water enters, the heat exchanger activates, resulting in heating the incoming cold water.

Heat inside a tankless water heater gets shifted from one source to another due to the heat exchanger. Many other household appliances, such as the refrigerator and air conditioner also have a heat exchanger inside the main unit. In a tankless water heater, the heat generated by gas-fired burners or electric coils is transferred to warm incoming cold water. Incoming cold water circulates in the activated heat exchanger, which allows it to heat the cold water to the set temperature as per your need.
