This means that energy is not wasted on constantly reheating water in a storage tank, resulting in lower energy bills and reduced environmental impact.

How Does a Tankless Water Heater Work?

To understand how a tankless water heater works, it’s important to know that it heats the water using either a gas burner or an electric element. When a hot water tap is turned on, cold water flows through the unit’s heat exchanger, where it is rapidly heated to the desired temperature. This process allows for an endless supply of hot water, as long as the unit is properly sized for the household’s needs.

Let’s delve deeper into the mechanics of a tankless water heater. When the hot water tap is opened, a flow sensor in the unit detects the water flow and signals the heating element to activate. In a gas-powered tankless water heater, a gas burner ignites and heats the water as it passes through the heat exchanger. On the other hand, an electric tankless water heater uses an electric element to generate heat.

Once the water reaches the desired temperature, it is delivered to the faucet or showerhead. The heating process is instantaneous, ensuring that hot water is available on demand. This is particularly beneficial for households with high hot water usage, as there is no need to wait for a storage tank to refill and reheat the water.

It’s worth noting that the size of the tankless water heater is crucial for its performance. If the unit is undersized, it may struggle to meet the household’s hot water demands, resulting in lukewarm water or fluctuations in temperature.
