Thinking about tackling the descaling process on your Navien tankless water heater yourself? This video is your one-stop shop for a clear and concise walkthrough! We'll guide you through every step, from prepping the unit to flushing the system, ensuring optimal performance for years to come.

But before we dive in, is a tankless water heater right for you? Tankless units offer a multitude of benefits over traditional tank water heaters. They heat water on demand, eliminating standby energy loss and saving you money on your utility bills. Plus, their compact size frees up valuable floor space, making them ideal for smaller homes or those with limited storage.

Now, back to maintenance! Regular descaling is crucial for maintaining your Navien tankless water heater's efficiency. Hard water minerals can build up in the heat exchanger, reducing flow and leading to premature failure. By following the steps in this video, you can effectively remove these mineral deposits and keep your hot water flowing smoothly.

Remember, if you're not comfortable performing the descaling process yourself, it's always best to consult a qualified plumber. But with this detailed guide, you'll have all the information you need to tackle this DIY project and ensure your Navien tankless water heater continues to provide endless hot water for your home.
