The system usually heat waters using an element that is commonly known as a heat exchanger. This heat exchanger either works by gas or electricity.

So now that you have an essential prior to how tankless water heater works, let’s jump right into the topic, so why does it need maintenance.

Main reasons why tankless water heater needs regular maintenance

Scale gathers in the tank system much slower than the tankless system. If you live in a hard water zone, you should have been a little bit conscious about this factor named “hard water”.

Now, what is it? Well, hard water is a type of water which contains mineral in it. Predominantly, calcium and magnesium. These minerals build in the heat exchanger, and then they end up blocking the pathway. So water can no longer flow by the passage.

Over the time being, this reduces the lifespan of the heater and increase the energy cost.

In addition to this- the mineral buildup on the heat exchanger can cause immense damage. It also requires the system to be replaced at the end, which is not really worth enough. Moreover, the manufacture will not accept any responsibility for this type of damage.

In a maintenance visit, the professional would descale the whole system, which is also known as sublime. This will make sure that there’s no buildup on your systems passage. You should descale the entire system to a professional at least once a year. But there are some few cases where you have to descale it twice and more than twice a year.

Is it necessary to descale the whole system more than once a year?

You might have to descale the system twice in a year if,

  • The area you live in is a hard water zone: No matter where you live, the water entering your heater is always filled with minerals. Yet, in some places, the water contains much more minerals than the average, which professionals declared as a hard water zone.
  • If you’re living in a hard water zone, your tankless system will require descaling twice a year.
  • Your tankless heater is set to a high temperature: If your water heater temperature is set massively high, it would be very risky and troublesome. In the meantime, the system might get damaged.
  • Many chemicals dissolve much faster with the presence of heat. So the hotter your water is, the faster scale builds around the passage or pathway. To omit this, check the thermostat of your tankless water heater to know what temperature it’s set to.
  • If the thermostat indicates much temperature than 120 degrees Fahrenheit, it’s high time to call a professional, descale the whole system, and clean the mineral build from the passage.

Conclusion

We were talking about “How often to descale tankless water heater” as described above. If you check the heater regularly, there wouldn’t be many problems. Apart from that- as hard water affects the heater, you can also apply some basic home remedies. But, calling a professional is always the best decision.
