Tankless Water Heaters – Are They Worth Investing In?

Taking a hot shower in the morning is not only a part of most people’s morning routine but it is also one of the joys of living. It gives you time to reflect, get clean and ready for the day.

When it comes to how you get your hot shower, there are essentially only two options. You can either heat the water in a tank or use a tankless water heater.

The tank heater is the traditional form of heating water in a house. However, they have several drawbacks the foremost being that you have to wait for the water in the tank to be heated to use it.

On the other hand, a tankless heater offers the chance of endless hot water supply. The question is are tankless water heaters worth the investment? The following points should answer that question:


1. Less Energy Costs

The major benefit of a tankless water heater is that you will save a lot on energy bills. The reason is that a tankless water heater uses a lot less energy to heat water than a tanked one. A tankless water heater heats the water only when necessary whereas a tanked one always has to heat a tank full of water to keep it hot. The result is that you can save a tremendous amount by using a tankless heater.

2. Durability

When you invest in a tankless water heater, then you can expect it to have a longer lifespan than a tanked heater. A tankless water heater only heats water on demand so the constituent parts are used less often than a tanked heater.

Moreover, storing water in a tank continually erodes it, especially hot water. A tankless water heater should give you at least two decades of service if well maintained.

3. Environmentally Friendly

When using a tanked water heater, you will use a lot of energy to repeatedly heat up a lot of water even when you are not home. It can add up to a substantial amount of energy consumption. The professionals behind waterheaterleakinginfo.com/best-electric-tankless point out that tankless water heaters will have varying levels of energy consumption. Some tankless water heaters use up to 95% less energy than tanked ones. We mostly burn fossil fuels to generate the electricity available in most homes. Therefore, tankless water heaters are much better for the environment than the alternative.

4. Clean and Secure

Heating water in a large and storing it there usually leaves the water with a lot of impurities. A tankless water heater is cleaner because water is heated at the point of usage. Moreover, a tanked water heater will typically be located outside your home which is a large security risk. A tankless water heater will be installed inside your home hence it is safer.


1. Expensive

An electric or gas tankless water heater is a technological marvel and a quite recent invention. They are also much more efficient at heating water than tanked water heaters.

For those and other reasons, tankless water heaters cost a lot more than regular tanked water heaters. The margin of difference in the price tag can be very significant in some cases.                                

2. Installation Costs

In addition to being expensive to buy, tankless water heaters are also dear to install. The initial purchase plus the installation costs can add up to a tidy sum. One of the reasons why it is so expensive to install tankless water heaters is that they need a water softener to work properly. These costs might offset the energy costs of having a tankless water heater in your home.

When you install a tankless water heater, you should have a qualified and registered plumber to do so. You need to ensure that the tankless water heater is installed safely and efficiently.

3. Limited Hot Water Supply

There are those who argue tankless water heaters are not really able to supply a continuous flow of hot water. To be more accurate, they say that a tankless water heater is unable to provide enough hot water for a home with a family.

A tankless water heater may be unable to provide hot water in some situations for example if two showers are running simultaneously. Therefore, a tankless water heater might be better for a home with fewer inhabitants than one with more.

In summary, there are pros and cons to using a tankless water heater. You can see some of them outlined above. 

The benefits of a tankless water heater far outweigh the drawbacks and are hence a worthy investment to make. It is especially so in the long run despite a tankless water having a much larger initial capital outlay than traditional heaters. It is up to you to decide if the investment is worth it to you.
