What to Expect from a Tankless Water Heater

What Exactly Is a Tankless Water Heater?

Tankless water heaters produce hot water on demand, which saves energy compared to standard storage-tank water heaters. Coldwater goes through the tankless unit and is heated with gas or electricity, resulting in a continuous supply of hot water until the tap is turned off. They’re also known as instantaneous or demand-type water heaters because of this.

To comprehend a tankless water heater, you must first grasp how a traditional water heater works. In a typical heater system, your water is stored and heated in a big tank. The tank continuously warms the water to maintain a steady temperature, ensuring that you have hot water when you need it. Even if you aren’t using hot water, you are consuming (and wasting) electricity. As the title suggests, tankless systems do not have a huge storage tank. Tankless water heaters save energy by heating incoming water “as required” or “on-demand” with high-powered burners that swiftly heat the water as it passes through a heat exchanger.

What Tankless Water Heater Offers

Eco-friendly/Energy Saver

According to U.S. Department of Energy findings, a tankless water heater is 24% to 34% more energy-efficient than storage tank water heaters. Because hot water is supplied on demand, standby heat loss is almost eliminated. Tank-style water on the other hand heaters store water in a tank that is heated and reheated as needed.


Tankless water heaters can be a great way to reduce your home energy costs and heat your water more productively. A tankless water heater will pay for itself in a matter of years, especially if you reside in a region where energy is expensive.

Save Space

As opposed to their traditional counterpart, Tankless Water Heaters are compact and come in a variety of elegant designs. Not having a storage tank allows them to be fit anywhere and thus, are a great option if you’re looking to free up space in your home, or if you have limited room.

Continuous Supply

Because tankless water heaters heat cold water on demand, you can enjoy hot water for as long as the faucet is turned on. A tankless water heater allows you to relish a hot shower for as long as you like, no longer worried about consuming all of your water heater’s storage tank.

Replaceable Parts

Because tankless water heaters are intended to be repaired, their service life is prolonged and can last 20 years up to or longer. If a tank-style water heater starts to leak, the entire unit will most likely need to be replaced. Tankless water heaters, on the other hand, are designed such that practically every component may be replaced with a new one.

Fresh Water

With no storage tank, hot water is never sitting in a tankless water heater that may contain rust and other toxic minerals. When hot water is required, it’s heated on the spot and delivered immediately.

Things to Ponder

Though they last longer and save energy, tankless water heaters have much higher upfront costs. Estimated cost for a typical tankless heater range from $800 to $1,150 per unit—compared to around $450 to $750 for a traditional system. The installation costs of tankless heaters are also more expensive than those of traditional. Moreover, the flow rate of hot water for a tankless water heater is considerably less than a traditional water heater.
