Tankless Water Heater vs Tank: Which is Right for You?

If you're in the market for a new water heater, you may be wondering which is better: tankless water heater vs tank. Both types of water heaters have advantages and disadvantages, so it's important to understand the differences between them before making a decision.

Tankless water heaters, also known as on-demand water heaters, heat water as it flows through the unit rather than storing hot water in a tank. On the other hand, storage tank water heaters store hot water in a large tank, ready for use whenever needed.

In this article we will compare the two options to help you determine the best choice for your home!

Key Takeaways

• Tankless water heaters are more energy-efficient and provide endless hot water, but can be more expensive upfront and may require significant upgrades to your home's electrical or gas systems.
• Storage tank water heaters are less expensive and easier to install, but take up more space, may run out of hot water, and are less energy-efficient.
• When choosing between a tankless water heater and a storage tank model, consider factors such as your hot water usage, energy efficiency goals, and budget.

Understanding Water Heaters

If you're in the market for a new water heater, you have two primary choices: tankless water heater vs tank. Both types have their pros and cons, so it's important to understand how they work and what they offer before making a decision.

How Tank Heaters Work

Tank water heaters are the traditional choice for most homes. They work by heating water and storing it in a tank until it's needed. When you turn on a hot water tap, the water flows out of the tank and through your pipes.

One of the most significant advantages of tank water heaters is their affordability. They typically cost less than tankless models, and installation is often more straightforward and less expensive.

 However, they do have some downsides. For one, they can take up a lot of space, especially if you have a large family or high hot water demands. Additionally, tankless heaters are less energy-efficient than they are, which can lead to higher utility bills over time.

How Tankless Heaters Work

You may be wondering, are tankless water heaters good? Tankless water heaters work differently than tank heaters:

• They heat water on demand as it flows through your pipes. When you turn on a hot water tap, the tankless heater kicks on and heats the water as it passes through.
• Tankless water heaters are energy efficient. Because they only heat water as needed, they use less energy than tank heaters. This can lead to significant cost savings, especially if you have a large family or high hot water demands.
• They can be more expensive to purchase and install than tank heaters.
• They may be unable to keep up with high hot water demands, so if you have a large family or frequently use multiple hot water sources at once, there may be better choices than a tankless heater.

In summary, both tank and tankless water heaters have advantages and disadvantages. Before making a decision, consider your hot water needs, budget, and space constraints.

Comparing Costs

When it comes to water heaters, the cost is an important factor to consider. In this section, we will compare the initial cost and installation, as well as the cost efficiency over time, of tankless vs tank water heater.

Initial Cost and Installation

The initial cost of a tankless water heater is generally higher than that of a tank storage water heater. According to Forbes, the average installation cost for a water heater is between $825 and $1,700. You can expect to pay about $1,500 for parts and labor.

Tankless heaters are much more expensive than traditional tank water heaters, with on-demand water heaters coming with a much higher installation cost.

Electric tankless water heaters can have even higher installation costs due to the need for larger electrical service and wiring. However, tankless water heaters are generally more compact and can be hung on the wall or stowed away in a small closet or cabinet to save floor space.

Cost Efficiency Over Time

Due to their higher initial cost a common question homeowners ponder over is are tankless water heaters worth it?

Despite their high cost they can be more cost-efficient:

• Tankless water heaters heat water on demand, which means they only use energy when hot water is needed. This can lead to significant energy savings over time, especially if you have a large family or use hot water.
• According to a Drinking Water comparison, tankless water heaters can be up to 34% more energy-efficient than tank storage water heaters. This can result in lower energy bills and a lower overall cost of ownership over time.
• Tankless water heaters generally have a longer lifespan than tank storage water heaters, so you may have to replace them less often. This can also lead to cost savings over time.

In summary, while the initial cost and installation of a tankless water heater may be higher than that of a tank storage water heater, the cost efficiency over time can make up for the difference.

A tankless water heater may be the way to go if you are looking for a more energy-efficient and cost-effective option.

Evaluating Energy and Efficiency

When it comes to evaluating energy and efficiency, tankless water heaters have some advantages over traditional tank models. Here are some things to consider when comparing the two.

Energy Efficiency of Tankless Units

One of the primary benefits of tankless water heaters is that they are more energy-efficient than traditional tank models. This is because they only heat water as it is needed, rather than constantly heating and storing a large volume of water.

According to the Department of Energy, tankless water heaters can be up to 34% more energy-efficient than traditional tank models for homes that use 41 gallons or less of hot water per day. For homes that use more hot water, the energy savings may be less, but still significant.

Efficiency Comparison of Tank Models

While tankless water heaters are generally more energy-efficient than traditional tank models, it's important to note that not all tank models are created equal. Some newer tank models are designed to be more energy efficient than older models and may offer similar energy savings to tankless models.

When comparing tank models, look for thicker insulation, improved heating elements, and better temperature control. These features can improve traditional tank models' efficiency, making them a more cost-effective option for some homeowners.

Overall, tankless water heaters have some clear advantages over traditional tank models when it comes to energy and efficiency. However, it's essential to consider all the factors involved, including environmental impact and utility bills, when deciding which type of water heater to choose.

Installation and Space Considerations

When considering a new water heater, installation and space requirements are important factors to consider. Here are some things to keep in mind for both tankless and tank water heaters.

Space Requirements

One of the main advantages of tankless water heaters is that they are much smaller than traditional tank heaters. This means they can be installed in smaller spaces, freeing up valuable real estate in your home. Tankless heaters can be mounted on a wall, while traditional tanks require a dedicated floor space.

However, it is important to note that tankless heaters still require access to a gas line or electrical outlet, so installation in certain areas of your home may still be limited.

Installation Complexity

Regarding installation complexity, tankless water heaters can be more challenging than traditional tanks. Tankless heaters require specialized venting, which can add to the installation cost.

Additionally, if you are upgrading from a traditional tank to a tankless heater, you may need to upgrade your gas line or electrical service to accommodate the new unit.
