Are Tankless Water Heaters Worth It? Pros & Cons

A tankless water heater is an updated version in the world of heating systems. It is highly energy-efficient, and the water only gets heated up when you need it.

This means that during the time you turn on the faucet, the internal heating component heats the incoming water on your demand, and after you are done with it, the water won’t be heated further.

If you are planning to buy one, it is obvious that you are taking information from various sources because you don’t want your investment to go to waste. Some might inform you of the positive sides, and who knows, you might also get some negativity from the critics. This can turn out to be a confusing situation for you.

To solve your problem, the following article is written for you. With the knowledge of this heater’s pros and cons, you will be able to narrow your search and make a final decision about your choice. So, let’s check it out.


Down below are a few of the pros for you to look at. Without farther due let’s dive in and enlighten ourselves.

  • Flexible to Use

You can use it very easily with a simple turn on the faucet. The flow rate will be continuous, and it can provide you hot water of around 2 to 5 gallons per minute. It depends on the kind of heater that you are going to install because the size and quality will determine the water flow rate.

The size of this heating system is small, and you can easily install it anywhere inside your home, whether it is inside a cabinet or even a closet. If you prefer to fix it in the outdoor area, you are most welcome. This modern version is immune to any weather condition so, you don’t have to worry.

  • Saves Money

The heater doesn’t heat the water continuously throughout the day, and this saves a lot of energy. As a result, your electricity or gas bill will be lower than usual. If you use the gas heater instead of the electric one, you will be able to save an additional amount of money.

  • Environmentally Friendly

There will be less emission of gases into the atmosphere because the burner inside the heater won’t be activated 24/7. So, there will be less burning of gas or the consumption of electricity, and the overall process will be healthier for the environment.

  • Highly Reliable

You will be able to use it for around two decades (20 years) or more if you can maintain it properly. There will be no rust issues, and this quality makes the heater very reliable for everyone.

  • Consists of a Built-in Safety Mechanism

The majority of the heater comes with a built-in flame sensor, anti-freezing mechanism, cut-off fuse (overheat), and many more. If a situation comes where there is a chance of flame, the sensor will detect it and will shield the heater.

In colder climates, the heater won’t get frozen due to the anti-freezing circuit. In case there is a huge rise in temperature that can happen out of the blue, the cut-off fuse will shut down the heater from operating further.

  • Parts Are Easily Replaceable

If you are facing some problems with the heater, you don’t have to replace the whole system. You just need to find out the malfunctioning parts and replace them.


But, like every other product out there this too has its fair share of disadvantages. Let’s have a look at them.

  • Expensive

You must have a good budget in order to get this. Initially, you might feel a bit negative, but with time, you will be happy with the fact that your electricity or gas bills are decreasing. This will neutralize the whole situation.

  • Need Home Modification

If you are using the gas tankless water heater, there must be a dedicated gas line, or else it won’t operate properly. This installation will cost you some additional money. In the case of the electric one, you need to upgrade your home electrical system.

  • Flow Rate Barriers

There can be a time when you have to use the shower, kitchen tap, washing machine, and other home appliances at the same time.

Sure, you will get hot water supply, but the flow rate won’t be as fast as the time when you are using only a single appliance. This can turn out to be a headache for you if you are in a hurry or emergency. To overcome this, you will need more than one heater to avoid this scenario.
