Benefits Of Having a Tankless Water System

Tankless water heaters, also known as demand-type or instantaneous water heaters, normally provide hot water only as it’s needed.

Unlike the storage water heaters, tankless water heaters don’t usually produce standby energy losses, and this is quite a cost-saving measure.

But beyond, cost-efficiency, there’re other numerous benefits of tankless water heaters, which we shall look at below.

However, before we look at the benefits of a tankless water system, it would be prudent that we have a rudimentary understanding of how tankless water systems function.

How A Tankless System Functions

Tankless heaters normally heat water directly.

They don't need a storage tank

 But instead heat the water as it travels through the system.

It’s from here that the water is heated either through a gas burner or electric elements.

Either way, this water system helps to deliver a constant supply of hot water.

With a tankless system, there's no need to wait for the water to heat up before using it.

Now that we have an idea of how tankless water systems work, now let’s dive in and look at some of the benefits of using this water system.

Provide Hot Water On-Demand

As we've just mentioned above, a tankless water system operates on-demand, or rather when your hot water.

Now, the on-demand water provision is beneficial in several ways.

One major benefit of on-demand is the reduction of energy costs. Generally, the on-demand water system will save your energy costs as much as 35% a year.

The second major benefit of the on-demand water system is energy efficiency. A report by Energy Star indicates that some of the tankless units have an extremely high energy factor peaking up to 95.

Again, this will further enhance the reduction in energy costs while at the same time.


Generally, tankless water systems are more reliable than the storage system.

If the tankless water system is properly sized, then it can efficiently deliver a continuous flow of water at the desired temperature levels.

A tankless system can deliver anywhere between 5 to 7 gallons of water per minute.

Even better, depending on your source of water, a tankless hot water system can never run out of hot water.

Energy Efficient

A majority of the water systems do not need the water to remain hot when not in use. This means that you won't need energy input to maintain high temperatures of the stored water. 

More so, hot water systems consume less energy in heating water, which implies less waiting time for taking showers or even cleaning dishes. 

In a hot water system, the water goes hot in five to ten seconds, which will save you a lot of time that you would otherwise use while waiting for the water to warm up. 

Water Upkeep 

Hot water systems help you to conserve water. If you select a tank hot water system, getting the right size tank for your home's hot water consumption will help you to conserve water. On the other hand, if you go for the tankless hot water system, it also saves water because it delivers hot water in seconds on demand. You should compare hot water systems to find the most efficient water-conserving model in your home. This will help save some money for your water bills every month.


Another striking benefit of the tankless water system is a longer life expectancy.

Tankless systems last longer, and while they have a higher purchase price than the conventional storage tanks, they normally offset the initial purchase price.

In generally, a majority of these heaters have a generous life expectancy of 20 years.

Additionally, they’ve easily replicable parts, and this helps to enhance their life by many more years.

This is in contrast to the conventional water storage heaters with a life expectancy of 10 to 15 years.


Tankless water heaters do not need a space for holding water.

So, in their very nature, they're compact, and they normally take less space compared to the conventional tanks.

Their compactness also means they're versatile and can be used or even fixed anywhere in the house.


Tankless water systems normally score high on the safety aspect.

The safety of the tankless water systems is promoted by the fact that they only operate when warm water is required.

This is contrary to the conventional storage units that have to stay permanently on.

Also, the modern tankless water systems are fitted with a plethora of innovative feature that helps to bolster the overall safety.

For instance, some of the models include monitoring systems that provide accurate details on the water pressure and flow, and in case of system failure, the machine automatically turns off the heater instantly.


While there're numerous benefits to the tankless water system, proper installation is always of the essence.

Installing a water system is not a simple Do-it-yourself unless you've pro-level skills.
