Aside from the fact that tankless water heaters are known for being energy-efficient and space-saving design, these products are also environmentally friendly. The products are popular models mostly used in Asian and European countries. Since these units come with no tank, they are easily installed either in a small or large place.
They use a lot of energy to heat the water for an extended period. Do you know what? These models supply water simultaneously, even when not in use. One of the popular brands that produce tankless water is Navien. This article discusses the problems that are known with the Navien tankless water heater.
Navien Tankless Water Heater
When it comes to the production of durable, water-efficient, and reliable water heaters, Navien is one of the best brands on the shelves. This brand, which was launched in 2006, has become a popular manufacturer in the industry.
Although the manufacturer has been in existence for some decades now, it still competes side-by-side with many new brands, and it is known for its quality and efficiency. Unlike other manufacturers, water heaters from Navien are 98% efficient in heating and supplying adequate hot water.
How Navien Tankless Water Heater Works?
Navien tankless water heaters work in a way in which you would spend less money to enjoy adequate hot water supply. This product begins by opening the hot water tap, which detects the flow. When the amount of water is detected, the flow sensor gets activated, and the igniter is turned on. Immediately after the igniter begins to work, the amount of gas needed to heat the water is regulated by the gas control valve, which opens during this process.
To further support the gas, the vents and fan provide the flame to heat. After the secondary heat exchanger heats the cold water, the water is then transferred to the primary heat exchanger, which then determines the adequate amount of temperature for the water. Lastly, the water is transferred to the faucet for use!
Problems of Navien tankless water heater
Like other tankless water on the market today, Navien tankless water heaters also have different issues that they experience. Let’s consider the following problems of these tankless water heaters.
1. Flow Sensor
One of the major problems common to Navien tankless water heaters is a quick erosion of the flow sensor. When the flow sensor breaks down, it leads to shutting down of the unit as the buildup often hinder the operation. Poor flow sensor leads to little or no supply of hot water. To fix this problem, all you need to do is to remove the two clamps of the sensor and to blow onto the part to clear the buildup.
Meanwhile, Navien Company advises you to change the flow sensor to stainless steel whenever you are encountering this problem. Likewise, the other parts of these water heaters that can cause the machine to stop working can also be changed as you would get these parts easily on the market. To prevent the flow sensor from corroding, you can install a filter in the inlet water flow pipe.
2. Control Board
Another problem that is known with Navien tankless water heaters is the failure of the control board. Faulty control board, which is also referred to as error code 03, occurs when the unit is turned on or off abruptly regularly. Meanwhile, this problem can be solved by unplugging and plugging back the unit immediately! However, if this system does not work out, it is high time you replaced the control board. These you can get quickly on the market.
3. Heat Exchanger
Unlike other problems of Navien tankless water heaters, the heat exchanger issue is a rare case. This device can either get decay or dry within a limited time. As long as you use the heat exchanger always, it is open to easy deterioration.
Although the heat exchangers can be repaired like other parts of the water heater, it is better to change it without delay. This is because the decayed heat exchanger can allow the exhaust gases to enter your home. These exhaust gases can be unhealthy for you and your family. However, this part of the water heater is covered under the warranty if the Navien company.
