Tankless Water Heaters


What is a tankless water heater?

Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only when you need it. Unlike the traditional storage water heaters, they don’t produce standby energy losses, and can save you money.

  • Tankless water heaters are able to provide your home with the hot water you need, without the bills you do not.
    Tankless water heaters provide hot water only as it is needed.

How it works

Tankless (a.k.a. “demand”) water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water.

Do I only need one tankless heater?

The hot water output for a tankless water heater is typically 2-5 gallons per minute. Installing multiple heaters is an option, but may not be required. A tankless water heater’s output does limit the flow rate. You can install a dedicated tankless water heater for appliances — such as a clothes washer or dishwater — that use a lot of hot water in your home.

When would I start seeing my money back from switching to tankless?

The initial cost of a tankless water heater is greater than that of a conventional storage water heater, but tankless water heaters will typically last longer and have lower operating and energy costs, which could offset its higher purchase price.

Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that extend their life by many more years. In contrast, storage water heaters last 10–15 years.
