How Does a Tankless Water Heater Work?

A traditional water heater also called a tank water heater generally utilizes a large storage tank of 30 gallons or more that is constantly heated until the water gets hot. Usually, these tanks hold enough hot water to meet the needs of the entire house. However, we’ve all been victims of the cold shower shock. These traditional heaters can be exhausted and take a long time to refill and reheat.

When you open a hot water tap, cold water enters the heater and triggers the powerful heating elements or burners. The hot water tap acts as an ignition key for the energy used to heat the hot water you need.

The water is heated as it flows through the heating elements or heat exchanger. As the water flow varies, the unit adjusts the heating elements or burner flame to maintain a constant temperature and maximum energy efficiency.

A flow sensor activates the gas burner, which warms the heat exchanger. Incoming cold water encircles the heat exchanger and leaves the heater at its set-point temperature. The combustion gases safely exit through a dedicated, sealed vent system. Tankless Water Heater requires a very minimum electric current to trigger the burner and to release the combusted air with the help of blower.

When the hot water tap is turned off, the heating system also turns off. The energy that is consumed is only for the hot water that is being used.

In case of Gas Tankless Water Heaters, the cold water flows through a water pipe that runs through a chamber that is heated by the flames. For Electric Tankless Water Heaters the heating elements are actually immersed in the water.

There are three primary types of tankless water heaters

  • Gas-powered
  • Propane-powered
  • Electric-powered

This efficient method can save homeowners hundreds in utility bills over the years.
