Tankless water heaters, also known as on-demand water heaters are often marketed as low maintenance water heaters. However, just because they are low maintenance does not mean that they are no maintenance. In actuality the level of maintenance will depend on several factors: A) the hardness of the water where you live and B) how hot the temperature is set. Just like their tank storage counterparts, it is ideal for a tankless water heater to be serviced at least once a year. Regular maintenance on any water heater is proven to extend the life of the water heater. The same holds true for tankless water heaters. In fact, tankless water heaters can last 20 years with proper maintenance. That is double the amount of traditional tank storage water heaters. This is what routine maintenance for your tankless water heaters looks like.
The Effects of Hard Water
Hard water is one of the main reasons why a water heater will fail, both tankless and storage tank types. That is because hard water contains mineral deposits, like calcium and magnesium that can
build up over time. With tankless water heaters, excessive mineral deposits can restrict the flow of water. As a result, your water heater has to work harder to keep up with demand. This requires more energy, and unfortunately leads to more wear and tear on the mechanical parts of the water heater. In the case of tank storage water heaters, excessive mineral deposits can also cause physical damage to the tank itself. Cracks and leaks are often the results of too many mineral deposits.
When the temperature is set too high, it can result in a limescale buildup on the heating exchange. Limescale develops faster in hotter temperatures. For areas that are prone to hard water, temperature settings are really important. If the temperature is set over 120° F, then you may want to schedule some routine maintenance for your tankless water heater.
Routine maintenance for tankless water heaters is just and important as maintenance for tank storage water heaters. A professional should always perform routine maintenance for tankless water heaters to ensure the job is done correctly, the water heater performs at optimum efficiency, and the warranty hasn’t defaulted. Many plumbing companies offer service agreements. This is a great way to stay on top of your maintenance to do’s.
