FAQ

Do I need a descaler with my tankless water heater?

If the mineral content in your water is high, it will result in a higher set water temperature and increased consumption of hot water in your home. As a result, you may need to descale your tankless water heater more frequently. This maintenance task can be carried out either by a professional or by yourself, provided you have the necessary equipment, materials, and skills.

Why does my tankless water heater turn blue when I flush with vinegar?

Don’t worry if you notice a slight blue color in the vinegar. It’s caused by small traces of copper corrosion from the heater’s tubes. The copper is responsible for giving it that blue hue, but there’s no need for concern.

What happens if you don t descale your tankless water heater?

If you neglect to flush your tankless water heater regularly, it can result in the accumulation of minerals and sediment within the filter and hose. This build-up can significantly impact the flow of water, ultimately leading to a lack of hot water. Unlike some plumbing issues that gradually worsen over time, the negative effects of a clogged tankless water heater can be sudden and noticeable.
