Scaling and Descaling Tankless Water Heaters


Tankless water heaters have gained popularity among homeowners, thanks to their energy-efficient operation and continuous hot water supply. However, like any complex appliance, tankless water heaters require regular maintenance to ensure their smooth operation. 

One common issue that can plague tankless water heaters is scaling, which is caused by the buildup of mineral deposits. In this post, we’ll discuss what scaling is, why it poses problems, and why it’s crucial to enlist the help of a professional to descale your tankless water heater. When dealing with scaling issues, we advise you to contact our technicians to arrange for the professional service that will get the job done right.

What Is Scaling?

Scaling is the accumulation of mineral deposits, primarily calcium and magnesium, on the internal components of a tankless water heater. These minerals are naturally present in most water sources, and when the water is heated, these deposits can precipitate and form solid buildups. Over time, this scaling can accumulate on the heat exchanger and other critical parts of a tankless water heater, resulting in decreased efficiency.

Why Is Scaling a Problem?

Scaling can lead to a range of issues with a tankless water heater:

  • Reduced Efficiency: Scaling acts as an insulating layer on the heat exchanger, diminishing its ability to transfer heat from the burner to the water effectively. As a result, the water heater must work harder and for longer periods to produce the same amount of hot water, leading to increased energy consumption.
  • Hot Water Supply Problems: Scaling can restrict water flow within the unit, causing uneven heating and fluctuations in the hot water supply. This can be inconvenient and frustrating for you and your family.
  • Shortened Lifespan: Left unaddressed, scaling can lead to overheating and damage to critical components of a tankless water heater. This can significantly reduce its expected lifespan and result in costly repairs.

Why You Should Call a Professional for Descaling

Descaling a tankless water heater is a complex process that requires expertise and specialized equipment. Here’s why it’s important to hire a professional for this task:

  • Safety: Descaling involves handling potentially corrosive chemicals and working with high-temperature components. Professionals are trained to perform this task safely, reducing the risk of accidents or injuries.
  • Proper Equipment: Professionals have access to the necessary tools and equipment, such as pumps and hoses, to descale a tankless water heater effectively.
  • Knowledge and Experience: Certified technicians have the knowledge and experience to assess the extent of scaling and choose the appropriate descaling solution for your specific unit.
  • Minimizing Damage: Professionals can minimize the risk of damage to your tankless water heater during the descaling process, ensuring its continued functionality.
  • Preventive Maintenance: A professional can also perform a thorough inspection of your tankless water heater, identifying and addressing any potential issues before they escalate.

Regular maintenance and timely attention to scaling issues can help you avoid more significant problems in the future with your tankless water heater. When it comes to descaling, trust the expertise of a qualified technician to get the job done right.
