How Do Tankless Water Heaters Work?

Last updated 5 years ago

Tankless water heaters offer homeowners a convenient, cost-effective, and space-saving way to provide hot water throughout the home. By creating hot water on demand, tankless water heaters are more energy-efficient and cost-effective than traditional water heaters. Let’s take a closer look at how tankless water heaters work:

Water Flow

When you turn on your hot water faucet, water will flow through the tankless water heater before it reaches your faucet. Depending on the type of water fixtures you have and the amount of hot water you will use, you can adjust the flow rate of the tankless water heater to provide just the right amount of hot water. Larger houses or houses with more hot water fixtures should choose a heater with a higher flow than smaller homes so that the right amount of hot water will be created.

Heat Transfer

In order to heat the water before it heads to your faucet, the tankless heater contains a powerful heat exchanger. These heat exchangers can contain electric coils or natural gas burners to heat the water. Once your faucet is turned on, the heat exchanger is activated by the oncoming flow of water. As the water passes through the tankless heater, it flows through the heat exchanger. The water is at the perfect, heated temperature once it reaches the tap.

Unlimited Hot Water

With a traditional hot water heater, a large quantity of water is slowly heated and then stored in a tank. When you choose a tankless heater, there is never a need to wait for the hot water to heat up. Instead, the heat exchanger creates an unlimited amount of hot water, whenever you need it.
