Expert analysis: Pros and cons of tankless water heaters

Energy Efficiency

Tankless water heaters, also known as on-demand water heaters, have gained popularity in recent years due to their energy-saving benefits. Unlike traditional storage tank water heaters, which constantly heat and store water, tankless water heaters heat water as it is needed. This eliminates standby heat loss, which can account for a significant portion of energy consumption in traditional water heaters.

According to a study by the U.S. Department of Energy, tankless water heaters can be up to 34% more energy efficient than conventional storage tank heaters. This translates to lower utility bills and reduced environmental impact.

Endless Hot Water Supply

One of the key advantages of tankless water heaters is their ability to provide a continuous supply of hot water. Traditional water heaters have a limited storage capacity, which can lead to running out of hot water during peak usage times or when multiple hot water outlets are being used simultaneously. With a tankless water heater, hot water is provided on-demand, ensuring a consistent supply for all your needs.

Space Savings

Another benefit of tankless water heaters is their compact size. Traditional water heaters with storage tanks can take up a significant amount of space in a utility room or basement. In contrast, tankless water heaters are much smaller and can be mounted on a wall. This frees up valuable space and allows for more flexible installation options.

Higher Initial Cost

While tankless water heaters offer many advantages, they do come with a higher initial cost compared to traditional water heaters. The price of a tankless system, including installation, can be two to three times higher. However, it’s important to consider the long-term savings in energy costs and the extended lifespan of tankless water heaters.

Installation Considerations

Installing a tankless water heater may require adjustments to your home’s plumbing and electrical systems. Because tankless heaters require a higher power supply, you may need to upgrade your electrical panel or install additional wiring. Additionally, depending on your hot water demand, you may need more than one tankless water heater to meet your needs. It’s essential to consult with a professional plumber or heating contractor to determine the right size and capacity for your home.

Maintenance Requirements

Proper maintenance is crucial to ensure the longevity and efficiency of a tankless water heater. Regular flushing of the system is necessary to remove any mineral deposits that can build up over time. It’s recommended to hire a professional to perform this maintenance task annually. Neglecting proper maintenance can lead to decreased performance and potential issues, such as reduced hot water flow or temperature fluctuations.


Tankless water heaters offer several advantages, including energy efficiency, endless hot water supply, and space savings. However, they come with a higher upfront cost and may require additional installation considerations. Regular maintenance is essential to keep them operating at peak performance. Considering these pros and cons can help you make an informed decision about whether a tankless water heater is the right choice for your home. Looking to dive deeper into the subject matter?
