Should I perform regular flushing and descaling on my Noritz EZ98 to prevent mineral buildup?

Regular flushing and descaling of your Noritz EZ98 tankless water heater is essential to prevent mineral buildup and maintain its efficient operation. Mineral buildup, primarily caused by hard water, can negatively impact the performance and lifespan of your tankless water heater. In this guide, we'll discuss why you should perform these maintenance tasks regularly.

* Hard Water and Mineral Buildup:
Mineral buildup, also known as scale or lime scale, is a common issue in areas with hard water. Hard water contains high levels of minerals, such as calcium and magnesium, which can precipitate out of the water when it's heated. Over time, these minerals accumulate on the heat exchanger and other internal components of your tankless water heater, forming a layer of scale.
* Impact on Efficiency:
The presence of scale on the heat exchanger reduces its ability to transfer heat effectively to the water. As a result, your tankless water heater will need to work harder and longer to heat the water to the desired temperature, leading to decreased efficiency. This can result in higher energy bills as the heater consumes more energy to achieve the same level of hot water output.
* Reduced Flow Rate:
Mineral buildup can also restrict the flow of water through the heat exchanger. This reduction in flow rate can lead to decreased water pressure and flow in your fixtures and appliances, affecting your overall water usage experience.
* Risk of Damage:
If left untreated, severe scale buildup can lead to overheating and damage to the heat exchanger and other components of the tankless water heater. This can result in costly repairs or even the need to replace the unit prematurely.
* Regular Flushing and Descaling:
To prevent these issues, it's crucial to perform regular flushing and descaling of your Noritz EZ98 tankless water heater. Flushing involves removing any loose debris and sediment from the unit, while descaling specifically targets the removal of mineral scale.
1. Flushing: You should flush your tankless water heater every six months to a year, depending on your water quality and usage patterns. Flushing involves using a pump and a descaling solution to circulate through the unit, dislodging and flushing away debris.
2. Descaling: Descaling is typically performed less frequently, about once a year or as needed based on your water quality. It involves using a descaling solution specifically designed to dissolve mineral scale. Follow the manufacturer's recommendations for the appropriate descaling solution and procedure for your Noritz EZ98 model.
* Extended Lifespan:
Regular maintenance not only ensures efficient operation but also extends the lifespan of your tankless water heater. By preventing the accumulation of scale and reducing strain on the components, you can avoid premature wear and tear, leading to a longer-lasting unit.

In conclusion, performing regular flushing and descaling of your Noritz EZ98 tankless water heater is essential to prevent mineral buildup, maintain efficiency, and prolong the appliance's lifespan. Hard water can lead to scale accumulation, which negatively affects performance, energy efficiency, and water flow. By adhering to a maintenance schedule that includes flushing and descaling, you can ensure that your tankless water heater continues to provide reliable hot water and avoids costly repairs or replacements in the future. Be sure to consult your heater's manual for specific maintenance instructions and recommended intervals.
