How Do Tankless Water Heaters Work?

A tankless water heater is a compact water heating system that does not require a conventional tank because, instead of storing hot water, it heats the water on demand as you use it in your household. As soon as you turn on any hot water tap in your home, a tankless water heater will take cold water and heat it immediately through a heat exchanger, then send it through your home’s plumbing system to wherever hot water is desired.

What are the Benefits of a Tankless Water Heater?


Tankless water heaters are wall mounted and very small compared to conventional tanks, which are large and freestanding. The size of tankless water heaters is attractive to both small-home dwellers and those with larger houses because it allows you to use your space more effectively and is not an eyesore. Tankless water heaters are typically more fuel efficient as well. 

No More Waiting Around for Hot Water

Because tankless units heat water on demand, you will never run out of hot water. No more waiting for a tank to heat up after running cold. 

Environmentally Friendly

Because tankless water heaters are so much more efficient than regular hot water tanks, you can feel good about saving energy and leaving a smaller footprint.

Longer Lasting

Tankless water heaters are much more durable than hot water tanks. Generally, they last more than double the lifespan of a conventional hot water tank.

Monthly Fuel Savings 

Although purchasing and installing a tankless water heater is more expensive up front than a hot water tank, it will save you money on your monthly fuel bills and is better for the environment. 

Is a Tankless Water Heater Right for Me?

Because of the benefits listed above, more and more people are upgrading to tankless water heaters in their homes. Generally speaking, these units are preferable to hot water tanks. If you have a smaller up-front budget, a conventional tank is the more affordable option, however a tankless model will pay for itself over time.
