If you’re looking for a water heater that can save you money, space, and energy, you might want to consider a tankless water heater. Unlike traditional water heaters that store hot water in a tank, tankless water heaters heat water only when you need it. This means you never run out of hot water, and you don’t waste energy keeping water hot when you don’t use it.

Noritz is a leading manufacturer of tankless water heaters that use natural gas or propane to heat water on demand, eliminating the need for a bulky storage tank and saving you money on your energy bills.

How long can you expect your Noritz tankless water heater to last, and what factors affect its life span? Below, we’ll answer these questions and give you some tips on how to extend the life of your Noritz tankless water heater.

The Average Life Span of a Noritz Tankless Water Heater

According to Noritz, their tankless gas water heaters can last up to 20 years. This is double the life span of a conventional water heater, which typically lasts 10 to 15 years. However, this isn’t a guarantee, as there are many factors that can influence how long a tankless water heater will last. Some of these factors include:

  • Water quality – Hard water, which contains high levels of minerals such as calcium and magnesium, can cause scale buildup inside a tankless on-demand water heater. This can reduce its efficiency and performance and eventually damage its components. To prevent this, you should install a water softener or a scale inhibitor in your plumbing system.
  • Frequency of maintenance – Like any appliance, a tankless water heater needs regular maintenance to keep it in good shape. You should flush your tankless water heater at least once a year to remove any sediment or debris that may have accumulated inside it. You should also replace the filter and check the venting system for any blockages or leaks.
  • Usage and demand – The more hot water you use, the more wear and tear your tankless water heater will experience. If you have a large household or multiple appliances that use hot water simultaneously, you may need a larger or more powerful tankless water heater to meet your needs. Otherwise, you may overload your unit and shorten its life span.

Maximizing the Life Span of Your Noritz Tankless Water Heater

Now that you know the factors that affect the life span of your Noritz tankless water heater, here are some tips on how to maximize its longevity:

  • Schedule regular maintenance – Regular maintenance, including flushing the unit and inspecting the heat exchanger, can prevent mineral buildup and extend the life span of your Noritz tankless water heater.
  • Use soft water – If you live in an area with hard water, consider using a water softener to reduce mineral buildup inside the Noritz tankless water heater.
  • Ensure proper installation – Hire a professional to install your Noritz tankless water heater to ensure it’s installed correctly and will last as long as possible.
  • Keep the area around the heater clean and clear – Make sure the area around your Noritz tankless water heater is clean and free of debris. This will ensure it’s getting enough air and won’t overheat, which can shorten its life span.

How to Tell if Your Noritz Tankless Water Heater Needs Replacement

If you follow the manufacturer’s recommendations and perform regular maintenance on your tankless water heater, you can expect it to last up to 20 years or more. However, even with proper care, your Noritz tankless water heater will eventually reach the end of its service life and need replacement. Some signs that indicate your tankless water heater is failing include:

  • Reduced hot water output or inconsistent temperature
  • Frequent error codes or system shutdowns
  • Leaks or cracks in the unit or its components
  • Loud noises or strange smells from the unit
  • Increased energy bills or gas consumption

If you notice any of these signs, you should contact a qualified technician to inspect your tankless water heater and determine if it can be repaired or if it needs replacement.
