Water Heater Tankless vs. Traditional: Which is Right for You?

September 20, 2024

Water heaters are essential components of your home. Selecting the perfect water heater for your needs can prove to be quite difficult. Because of the growing popularity of tankless water heaters, you need to know which option is best for you. Both traditional and tankless water heaters bring unique advantages and disadvantages to the mix. You need to know the differences between the two to help you make an informed decision about which one you will settle for.

Traditional Water Heater

If you have a traditional water heater or a storage water heater, it will store a large amount of hot water in a tank. When you turn on a hot water tap, the hot water from the tank flows to the faucet.

Pros of a Traditional Water Heater

The advantages of traditional water heaters are many. They typically have a lower initial cost compared to tankless models. As long as the tank has enough hot water, you can enjoy a consistent supply without worrying about running out. Traditional water heaters have proved to be reliable and long.

Cons of a Traditional Water Heater

There are disadvantages of a traditional heater as well. They can be less energy efficient, especially if you don't use all the hot water in the tank before it cools down. If you have multiple people using hot water simultaneously, you may run out of hot water. The continuous heating of the tank can lead to higher energy bills.

Tankless Water Heater

A tankless water heater, also known as an on-demand water heater, heats water instantly as it flows through the unit. It doesn't store hot water, so you only use the energy needed to heat the water you're using.

Pros of Tankless Water Heaters

People are opting for these water heaters as they are more energy efficient than traditional models, leading to lower energy bills. As long as your unit can handle the demand, you'll have a continuous supply of hot water. Tankless water heaters are smaller and can be installed in various locations, including closets or basements.

Cons of Tankless Water Heaters

The investment required in tankless water heaters is higher than traditional models. Some tankless models have limitations on the flow rate, meaning you may experience reduced water pressure or have to wait for hot water to arrive. Installing a tankless water heater can be more complex than installing a traditional model, requiring professional expertise.

Getting the Right One For Your Property

If you have a large family or frequently use hot water, a tankless water heater may be the better option to ensure a consistent supply. Understand and assess your energy consumption and budget. If you're concerned about energy efficiency and long-term costs, a tankless water heater can be a worthwhile investment. Space is another factor. If you have limited space, a tankless water heater can be a more practical choice. If you live in a colder climate, a tankless water heater may need to work harder to heat water, potentially affecting its efficiency and longevity.


Ultimately, the decision of whether to choose a traditional or tankless water heater depends on what you exactly need and prefer. If you hire an expert, they can also guide you.
