Advantage of a Tankless Water Heater

Are you thinking of going tankless? Would you love to know some of the advantages of a tankless water heater? If you are a homeowner or considering buying a new home, you definitely want an energy-efficient home. Heating water is inevitable in almost every home. In fact, water heating costs average up to 30 percent of a home’s expenses. This is why many homeowners are concerned about saving energy.

You can keep the energy expenses low when you install a tankless water heater. It will save you up to $100 in a year as compared to the tank models. I will take you through the benefits of installing an on-demand water heater.

How Does a Tankless Water Heater Work?

Before we head to the advantages of a tankless water heater, it is important if you know how the unit works. When your hot tap water is on, the system draws cold water to the unit and it is heated using electric means or gas burner. The main advantage of these water heaters is that they provide a constant hot water supply on demand. This eliminates the need for storage tanks that need to be filled with water.  The systems can deliver up to 5 gallons per minute. However, other gas-fired models provide a high flow rate as compared to the electric units.

The Pros of Having a Tankless Water Heater

If you are wondering whether a tankless water heater system will benefit you, check out some of the advantages of installing such a system at home.

Reduce Energy Cost

This is probably the main advantage of having a tankless water heater. After all, who doesn’t love saving some cash? These types of tanks only work when there is a demand for hot water. The tank counterparts store the heated water and this ends up consuming more energy to keep the water hot. According to various researchers, a tankless water heater can save you up to 35 percent of energy cost. Some models have a high rating of up to 95 energy efficiency.

Although the initial cost of acquiring a tankless water heater is high, it will save you more money long term. A tankless water system used less water which leads to reduced consumption and low bills.

Instant Hot Water

Tankless water heaters do not store water. They provide hot water when it is needed. This is a benefit to a home with a large family. As compared to traditional tanks, when there are more people, the hot water available might not be enough to serve everybody. Going tankless provides everybody in the family with instant hot water that can serve all. So there will be no instances of some people postponing to take a shower.


When it comes to water heaters, you need a unit that you can depend on. No one wants disappointments when it comes to temperature levels or running out of water. Tankless water heaters are reliable and provide homeowners with a continuous supply of water at the set temperature levels. These heaters do not run out of water and they can supply up to 7 gallons of water per minute.


As compared to traditional models, tankless water heaters cost up to 3 times more than other tanks. After spending money, you definitely expect a durable unit, right? Tankless water filters are durable and they can last for more than 20 years as compared to other standard water heaters which last for up to 10 years. If you are considering installing a hot water system that will serve you for many years, I would recommend tankless water heaters. They are a great investment and you will never regret installing the unit.


If you want to save space, installing a tankless water heater will be a great idea. They do not take up much space as compared to the traditional models. Water heaters with tanks hold up to 60 gallons of water and this means that they need to be over 60 inches in height. As a result, they end up talking too much space. Tankless water heaters range up to 28 inches making them very compact. Their design makes it easy to install them in different places hence saving more space.

Long Warranty

Tankless water heaters come with a long warranty as compared to the traditional models. Their warranty can be up to 15 years while their counterparts carry a warranty of up to 6 years. This gives you some peace of mind and you are sure that your purchase is secure. Research also shows that when you install a tankless water heater, you will not have to deal with problems of water on the floor.

Eliminate Standby Heat Loss

With a tankless water heater system, you will not experience energy wastage when the water is in the tank or in the long pipes.


With traditional units, the possibility of raptured tanks and broken tanks is very common. This can lead to floor damages. When you are using a tankless water heater system, there will be no issues of raptured tanks or flooding. This makes them very safe.
