Why is it the Best Choice to Purchase a Tankless Water Heater

Tankless water heaters are a great option to consider if your tank system is starting to become less efficient.

Also called a demand or on-demand water heater, the system supplies your home with a reliable source of hot water that doesn’t become cold throughout the day.

They come in two different models – gas or electric-powered – to help personalize how the system works for you. The overall amount of water flow and capacity can also be changed to suit your needs.

These water systems offer a number of additional benefits that a homeowner can take advantage of. One such benefit is that your energy bills are lowered, saving you money in the long run that you can use for other uses around your home.

Tankless water heaters avoid the energy use that a traditional storage tank water heater has, instead idling while the tank needs to reheat the water.

This article covers some of the main reasons why it’s the best choice to buy a tankless water heater and how it can help your household. If you’re interested in learning about tankless systems, read more on tankless water heaters in Phoenix.

The benefits of a tankless water heater

Saves space

When compared to a traditional storage water heater, a tankless system gives you far more room in your house. The average water storage tank is about two feet wide and five feet tall.

Depending on where the storage tank system was installed, that amount of useful space is instead used up. On the other hand, the average tankless system only uses about 20% of the space that the traditional system does.

Has a longer product life

On average, a tankless water heater can last 20 years. With the proper maintenance, this timespan is increased even further, to approximately 30 years depending on the model and where you might live in the United States. In comparison, a traditional water heater is likely to last between 10 to 15 years.

The nearly doubled lifespan of a tankless system is most likely due to the fact that it only turns on when you use it, wearing down the parts less often. And, if the parts do need to be replaced, the parts are easily replaced and may even prolong the system’s lifespan.

Less damage if your water heater leaks or breaks

If your water heater is old, there’s a chance that the metal inside will break. This may be due to rust weakening the metal or the weather making it bend, yet when the storage water tank gets a crack, the water can result in excessive damage.

Tankless systems avoid that issue due to the fact it doesn’t store water inside the system. By drawing fresher water into its piping as heating is needed, any potential leaks from a tankless water heater are minimal.

Saves you on energy costs

As mentioned earlier, traditional storage-tank water heaters heat the water once it gets too cold.

When taking into consideration the amount of water a tank heater can hold, it means that gallons upon gallons of water are being reheated whenever the water’s temperature drops.

Tankless heaters provide a much more environmentally friendly option that actually saves you money the longer you have it.

Though it is rather costly, depending on the size and model that best suits your home, you’ll be saving more with a tankless system by the time a traditional one breaks down.

Different sizes, models, and types to suit your household

If you aren’t sure whether or not a tankless water heater will provide enough hot water for your entire family’s needs, you can always look into getting a larger capacity water heater.

All that’s needed for many houses is a 5 to 10 gallons per minute – or GPM – tankless water heater. If you tend to run many fixtures at once, you can purchase a tankless system with a higher GPU rate, with the maximum reaching 12 GPM.

On top of having a choice between the GPM and whether the power source is gas or electric, there’s also an option of installing a non-condensing tankless system or a condensing version.

Most tankless water heaters are likely to be of the non-condensing type, which use heat exchangers to heat the water and send the resulting hot exhaust out of your home.

Condensing water heaters, on the other hand, use this exhaust as a second way to heat the water. Though this type is pricier to install, you save even more due to the increase in energy efficiency.

Get access to hot water for as long as you need it

With the water being heated from the moment you turn on the faucet or shower, you get access to hot water as long as you have the tap on.

This means that, as long as you have access to running water, the tankless system can provide the house with hot water.

There is a limit on how many taps and showers can be run at the same time, though. Every tankless system can only heat so much water at a time. Too many taps running means that one of them will be getting cold water.

However, a larger capacity tankless water heater will solve this problem and provide you with the hot water you need.


With how long a tankless water heater lifespan is, the system ends up providing a number of benefits for as long as it lasts. Proper maintenance and checkups can further lengthen the lifespan as well. Depending on the model and the power source the water heater runs on, more energy is saved.

This can not only be used for other needs throughout the home but also pay back the costs gone into purchasing the system and the required parts.

Before making a choice on buying a tankless water heater, consider what your home’s hot water needs are. Tankless systems can be a big improvement for your household.
