Plumber checking on a tankless water heater

What is a Tankless Water Heater?

A tankless water heater varies from a traditional water heater in that it lacks a storage tank where water is continually kept, heated, and recirculated. Tankless water heaters are around the size of a medium suitcase and can be used both inside and outside the house. They have a heat exchanger and coils that heat the water as it goes through the water heater before being transferred to the home's water supply.

The significant advantage of tankless water heaters, according to many homeowners, is that the water is only heated as needed, saving a lot of energy.

Tankless water heaters are similar to conventional heaters in that they have water lines running to and from the heater unit and can run on gas or electricity. Order a Plumber Inc., on the other hand, only recommends tankless water heaters if you have a gas source.

Tankless water heaters are commonly thought to provide instant hot water, although this is inaccurate. Tankless water heaters continue to heat the water as it goes through the heat exchanger before delivering it to the taps of the residence. The distance between you and the tap will impact how quickly you get hot water. There are ways to speed up this process, such as installing recirculation systems that allow hot water to reach the taps quickly.

Tankless Water Heaters Advantages

Endless Hot Water

Unlimited hot water is one of the greatest tankless water heater benefits. Running out of hot water in the middle of a shower can be aggravating for homeowners with large families or who entertain frequently. With a tankless water heater, the water is heated and delivered to the tap as long as it is running.

Energy Efficiency

Tankless water heaters are incredibly energy efficient, with most models ranging from 85 to 98 percent efficiency. Unlike conventional tank water heaters, tankless water heaters do not run continually. The burners only turn on when water is needed (by turning on a faucet, dishwasher, washing machine, or shower), and they stay on for as long as the water is on.

There is no time wasted heating 40+ gallons of water with tankless water heaters, and the amount of hot water lost is negligible.


Tankless water heaters have a significant advantage over conventional water heaters in terms of standard warranties. Quality tankless water heaters come with 10- to 12-year warranties as usual, and most feature parts can be replaced, so the entire system does not have to be replaced all at once if something goes wrong. While the upfront cost is higher than a standard water heater, when you consider the benefits, warranties, and the cost of replacing a tank water heater every six or so years, tankless water heaters more than pay for themselves.

Space Saving

Tankless water heaters are popular because they give unlimited hot water and are energy efficient, but they also save space. Conventional water heaters are commonly found in garages and closets inside homes. Water heaters can take up a lot of space, depending on their size. Some water heaters are more than 5 feet tall and wide.

Tankless water heaters are around the size of a medium box or suitcase, and they can be mounted on the inside or outside of a building. They're ideal for smaller homes or those with limited space for a water heater and residences where the water heater can only be installed indoors.

Because tankless water heaters are compact and only heat water as required, homeowners can rest easy, knowing that their homes will not flood if the water heater breaks. At any given time, tankless water heaters only contain roughly 1 cup of water.
