You rely on your water heater every day. When you need hot water for showers, dishwashing, or laundry, your water heater helps with the job. These systems come in two varieties: tank water heaters and tankless water heaters. While they both serve the same purpose, they work in different ways. Here’s what you need to know about the differences between these two types of water heaters.
Get to Know a Tank and a Tankless Water Heater
When you think of a traditional water heater, the tank version comes to mind. This style has been used in homes for decades. It is designed to store a large amount of water, which is between 30 to 80 gallons. That water will remain hot in the tank until you are ready for it. All the water will stay at a set temperature. You will have it immediately available whenever you turn on the hot water.
This system uses electricity, gas, or propane to heat the water. As the water is used, the tank will refill and heat more water for your home. While you will usually have a consistent hot water supply, you could run out if you use too much in your home at one time.
A tankless water heater works a little differently. Unlike tank water heaters, these models do not store hot water. Instead, they heat the water on demand. The water will run through the unit when you turn on the faucet. It is heated by an electric or gas element to provide warm water. You have access to a continuous flow of hot water without storing it in a tank.
What Are the Differences Between Tank and Tankless Water Heaters?
Obviously, the biggest difference is that a tank water heater stores hot water in a large tank, while a tankless water heater heats water only when you need it.
Since a tank water heater needs to be constantly working to keep a large amount of water hot, it uses more energy. As a result, that can lead to higher utility bills. On the other hand, a tankless water heater only heats water when it’s needed. In that match-up, it is the more energy-efficient option.
Size is also an issue. Tank water heaters are large and bulky. You will need to find a space with plenty of room to install them. For that reason, you can find many of them in a basement, utility room, or closet. However, tankless water heaters are compact. These units can be mounted on a wall. In turn, that can save space. Plus, you have more options as to where you want to install them.
Speaking of installation, the initial cost of a tankless water heater is higher than that of a tank water heater. Tankless models need special installation. You might need to upgrade the gas lines or add venting to accommodate them. Tank models are pretty easy to install if you have enough space in your home.
Longevity is another difference between these two. The average lifespan of a tankless water heater is around 20 years, while it is 10 to 15 years for a tank water heater. Also, tankless systems require less maintenance because of the lack of a tank. With the tank heater, the metal tank can rust or corrode without proper maintenance.
Which Is the Better Choice?
Both of these options have their benefits and disadvantages. When it comes time to choose one, that will depend on the specific needs of your home.
A tank water heater may be the better option if you have a large household that needs a lot of hot water at one time. Since it can store a large amount of water, you will never worry about running out of water and getting stuck with a cold shower again.
A tankless water heater is the better choice for those who want to save on utility bills. While the initial cost is higher, you can enjoy long-term savings on your energy bills.
The tankless water heater can save valuable square footage in your home if you are limited in space. This system is smaller and can be mounted almost anywhere, such as a wall.
Should you switch your current water heater? That depends. Upgrading the water heater will depend on your household’s hot water usage, budget, and energy efficiency goals.
