Tankless water heaters are very popular. They are power efficient and supply hot water on demand. However, many people often ask: “how long do tankless water heaters last?”
We give you all the information you need on that subject here. Once you know how long they last, you can make better decisions for your space.h
Why Do I Need Tankless Water Heaters?
Also named on-demand water heaters, tankless water heaters supply hot water when required. They do not need a storage tank for hot water since the water is heated as it goes through the system. It eliminates the need for heating the water and holding it for later.
Unlike tank-based – or traditional – water heaters, the tankless system offers many advantages. Some of them are more space, energy savings, unlimited hot water, no waiting time, and more. Let’s take a closer look at the benefits.

The Lifespan of Tankless Water Heaters
The average lifespan of a tankless water heatervaries from 15-20 years. However, many factors affect its durability. Regular maintenance, quality of materials, routine service, and water quality are some factors. Once you know these factors, you can care for your tankless water heater and increase its lifespan.
Factors Affecting the Lifespan of Tankless Water Heaters
Water Quality and Hardness
The water quality greatly impacts the lifespan of these units. Hard water has a great number of minerals like magnesium. These minerals build up inside the unit over time. It impacts the heater’s efficiency, performance, and longevity. Utilize a water softener or set up a water treatment system for removing hard water. This will lessen the build-up of minerals and extend the unit’s lifespan.
Usage Patterns and Demand
The demand for hot water in your house and usage patterns also affect its longevity. Tankless water heaters will wear out quicker if the heater is running to meet the high demands. Similarly, if the unit turns on and off due to low demand, it puts extra strain on its components. Practice water conservation and use the heater only when needed to optimize its lifespan.
Installation Quality
Correct installation of the heater is critical to optimize its performance and longevity. Improper installation, such as faulty connections, incorrect sizes, or inadequate ventilation cause malfunctions. The unit’s efficiency decreases and results in complete failure. Hire a trained professional for installing the unit. Heed the manufacturer’s guidelines to avoid any accidents.
Environmental Factors
The environment plays a vital role since it directly affects the heater. For example, the system can get damaged if the unit runs in freezing temperatures without proper protection or insulation. Extremely hot weather will affect the heater similarly. Moreover, corrosive environments or exposure to chemicals can accelerate the deterioration of components. Consider environmental conditions before installing a tankless water heater. So, find out how to insulate water heaters with protective covers or other insulation to increase longevity.
Tips For Increasing the Lifespan of Tankless Water Heaters
Schedule regular maintenance and service to ensure it is in optimal condition.
Flush the unit periodically to remove any minerals inside – this will increase its efficiency.
Ensure the water pressure is within the recommended range. Avoid putting extra strain on the system.
Allow sufficient space around the unit so it gets good ventilation. This will prevent the system from overheating and preventing damage.
Find out if you have a gas or electric heater and ensure that those connections are not loose or faulty – call a professional for inspection or repair the system if needed.
Use water filters and softeners to reduce the impact of hard water and lessen mineral buildup.
Consult experts for complex issues such as malfunctioning problems or servicing and repairing.
Is Your Tankless Water Heater Is Failing
Many signs indicate a heater is failing or not working. Some of these are:
insufficient or inconsistent hot water supply
unusual noises
frequent code errors or malfunctions
a decrease in water temperature
We recommend you consult a skilled technician also if you face these problems.
Before You Replace a Failing Tankless Water Heater
It is crucial to weigh the advantages and disadvantages of replacing a failing tankless water heater. Purchasing a new system involves an upfront investment. But it gives long-term energy savings and improves efficiency.
Replacing it is cost-effective if it is nearing the end of its life or you have to repair it often. This will help save cash in the bigger picture. You can always consult a professional and discuss factors such as utility costs, energy efficiency ratings, and other things so you make an informed decision.
Tankless Water Heaters and Warranties
Always get a warranty when you buy such a system. Most reputable companies offer warranties that cover repairs and more. Some manufacturers give your money back if the unit is defective or if the components are not working.
Read the terms and details carefully because the terms of the warranty vary for each manufacturer. Check the duration of the warranty and additional conditions or requirements. A warranty gives monetary protection as well in case you face unexpected issues with your tankless water heater.
People Also Ask
Can I increase the lifespan of my tankless water heater with proper care?
Yes, proper care and upkeep can increase the lifespan of a tankless water heater. Regular maintenance includes annual inspections and servicing. It helps in keeping the heater in top-notch condition. Moreover, flushing the system periodically removes minerals. It ensures good water pressure, thus, increasing the lifespan. Use water softeners and filters also. Each unit comes with manufacturer’s guidelines explaining proper care of the heater. Consult professional technicians for any difficulty or issue with your tankless water heater.
Do traditional tank-based water heaters last longer than tankless ones?
The tankless water heaters have a longer lifespan than traditional tank-based water heaters. On average, you can use your well-maintained tankless water heater for up to 20 years. However, it is also crucial to note that the lifespan of each unit varies and depends on factors like – unit quality, regular service, water quality, and usage patterns.
Are Tankless Water Heaters More Prone to Failure Than Traditional Heaters?
Tankless water heaters are more durable and reliable than tank-based water heaters. However, they can have issues over time. Regular service and maintenance are the keys to increasing its lifespan and reducing the chances of failure. This will help identify potential problems in the system and save it from failing. Another way of lowering failure risks is following the manufacturer’s guidelines.
Conclusion
Tankless water heaters are efficient and reliable. They meet your hot water needs and save energy as well. They last for almost 20 years. You can increase the lifespan through regular maintenance and service. Moreover, ensure proper ventilation, flush the system, and seek professional help. These steps are crucial for increasing the lifespan of your heater. Now you know how long a tankless water heater lasts; so you can care for it properly and enjoy the benefits for a long time.
