How to Choose Between Tankless and Conventional Water Heaters

When it comes to water heaters, the two main types you'll encounter are tankless and conventional water heaters. Both have their own unique advantages and disadvantages, leaving many homeowners confused about which type is the best fit for their needs.

In this blog post, we'll discuss the key differences between tankless and conventional water heaters, as well as the factors you should consider when making your decision.

How Tankless and Conventional Water Heaters Work

Before diving into the pros and cons of each type, it's important to understand how each water heater works. Tankless water heaters, also known as on-demand or instantaneous water heaters, heat water directly without the use of a storage tank.

When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by either a gas burner or an electric element. This means that you'll have a continuous supply of hot water, as long as you don't exceed the heater's flow rate.

On the other hand, conventional water heaters store and heat a large volume of water in a tank. The hot water is released from the top of the tank when you turn on a tap, and cold water enters the bottom of the tank to replace the hot water.

This process can be less efficient, as heat is lost through the walls of the tank and energy is consumed to keep the stored water hot.

Energy Efficiency

One of the main advantages of tankless water heaters is their energy efficiency. According to the U.S. Department of Energy, tankless water heaters can be up to 34% more energy efficient than conventional water heaters for homes that use 41 gallons or less of hot water per day.

This is because they only heat water when it's needed, eliminating the standby energy losses associated with storage tank water heaters. However, it's important to note that the energy savings can vary depending on your household's hot water usage and the efficiency of the specific water heater model you choose. In some cases, the energy savings may not be significant enough to offset the higher upfront cost of a tankless water heater.

Cost and Installation

Tankless water heaters generally have a higher upfront cost compared to conventional water heaters. They can also be more expensive to install, as they may require additional venting and gas line upgrades.

However, they tend to have a longer lifespan (20-30 years) compared to conventional water heaters (10-15 years), and their lower operating costs can help offset the initial investment over time.

Conventional water heaters are typically less expensive to purchase and install, but their shorter lifespan and lower energy efficiency may result in higher long-term costs.

Space Considerations

Another factor to consider when choosing between tankless and conventional water heaters is the amount of space you have available for installation.

Tankless water heaters are compact and can be mounted on a wall, making them ideal for smaller homes or tight spaces. Conventional water heaters, on the other hand, require a larger footprint to accommodate the storage tank.

Choosing the Right Water Heater for Your Needs

Ultimately, the decision between a tankless and conventional water heater will depend on your individual needs and preferences.

Here are some factors to consider when making your decision:

  • Energy efficiency: If reducing your energy consumption and utility bills is a priority, a tankless water heater may be a better fit for your home.
  • Upfront cost: If you're working with a tight budget, a conventional water heater may be more affordable initially.
  • Space: If you have limited space for installation, a tankless water heater's compact design may be more suitable.
  • Hot water demand: Consider your household's hot water usage patterns and choose a water heater that can meet your needs without exceeding its capacity.
