How Long Do Hot Water Heaters Last Typically?

The expenses are pretty high when you want to install such a device in the bathroom. The units are not available at reasonable rates, but the prices work as a one-time investment. So, the question that arises is whether these heaters are long-lasting. After all, you are putting in your money, which should help you with the benefits for an extended period.

Before discussing the period, you should understand the variation in these devices. It is essential to understand this because different heaters offer different functioning and duration.

So, there are two kinds of water heaters. They are as follows:

  • Tankless water heaters.
  • Water heaters with tanker storage.

The main difference in the variation of their lifespan is that they belong to different operational categories. The latter are subject to continuous heating, and the former begins heating water only when it is required by the person using it.

Longevity Of These Systems


In generic circumstances, the water heaters have been designed by the manufacturers so that they can last for a decade. Both kinds of heaters are designed to last for this period. Some factors are dependent on the longevity of the devices. Some of them are discussed as follows:

  • The kind of heater that you are planning to install.
  • The care that you extend towards the heater.
  • You can identify the issues that can arise during functioning in extreme weather conditions.
  • If you can come up with solutions that can help expand the device’s lifetime.

Life Of The Device For Water Heating


There are options like conventional water heaters. They can last for anything between 8 to 12 years. However, if you take care of the system and go for proper repairs and usage, it can go on for proper functioning for over 15 years. The tanks have an anode rod that helps to attract the corrosive elements that are present in water. It helps protect the interior lining of the system from issues like corrosion.

So, once the tank containing the liquid has completed its use of a decade, the rod begins to give up, and the efficiency is reduced. Corrosion begins to develop on the rod, and the interior begins to deteriorate as time passes. If you don’t get it changed or call a professional to intervene, the tank will start to malfunction. It will start leaking, and no water will be heated after one point.

The rise of technology has been helpful to the functioning of these devices that help to get the desired degree of hot liquids. The advancement in technology has improved the life of tankless ones. They are hence, preferred over the ones with tanks. The average life span of the tankless ones lasts for 2 decades approximately. If maintenance is proper and particular, the life span can be extended to 30 years, too.

Yes, you read that right.

The ability of these machines and systems is immense, no matter the size they belong to. You might think these heaters don’t get exposed to temperature issues like corrosion. The reality is that they are exposed to such issues, but the process is slower.

Signs To Look Whether Your Device Needs A Change Or Repair


You should look for some factors while planning to get your device changed or repaired. They are as follows:

  • The system is deteriorating in functioning and is getting old with time.
  • There have been changes in the water’s color from the heater. If you think the color is strange, you should consider changing it. Also, if there are slight tints in the water, you should call a professional for an inspection. If you want your hot water heater to get checked, you can visit this site and contact some experienced professionals.
  • Your heater begins to make strange noises at night and also begins making popping sounds. These sounds result from hard water that has made it to the heater interiors and requires repair.
  • If you see liquid pooling around the heater or there are chances that water can begin to stand near the unit, it is time for you to let the professionals intervene.

Factors To Consider To Check The Longevity Of The Device


The longevity of a such an electric product is subject to changes owing to the following factors like the following:

  • Quality

If the heater is beginning to heat the hard water frequently, the lifespan will be at stake. It will reduce by 2 years. The main reason behind this is that the hard water has minerals that can build limescale in the heater; hence, efficiency is at stake.

  • Maintenance Activities

You need to go for proper maintenance and repair of the device; otherwise, it will automatically reduce productivity for some time. You can expect a maintained machine to function for more than the expected time frame. Hence, it would help if you never skipped on this process. Also, don’t compromise while choosing the right professionals, as their expertise will take you places.

  • Power Drawn From The Kind Of Source

The next thing that should be noted is the source from which the leather draws its power for functioning. If you are going for an electric heater, it will show better functioning and durability. The life can be extended to 2 years minimum. Also, if it is made of fiberglass, you can expect it to function for a long duration compared to a heater with a steel body.

  • The Place Where You Plan To Install The Heater

The location of the heater is another thing that you should check for its longevity. Believe it or not but this one has an impact on the life of the device. If you install it in a temperature-controlled home, the results will be longer.


Hence, these devices can work for a decade, to say the least. However, any addition or subtraction to this period will be because of human intervention. Hence, you should ensure that you are taking steps that can add to its duration, functioning, and life.
