What should be the ideal water hardness level for the Noritz EZTR40, and how can I test and adjust it?
The ideal water hardness level for the Noritz EZTR40 tankless water heater is generally considered to be within the range of 7 to 10 grains per gallon (gpg) or 120 to 170 parts per million (ppm) as calcium carbonate (CaCO3). However, tankless water heaters like the Noritz EZTR40 can tolerate a wider range of water hardness levels without significant issues. Water hardness levels within the recommended range are less likely to lead to scale buildup, which can affect the heater's performance and efficiency.
Here's how you can test and adjust the water hardness level for your Noritz EZTR40:
Testing Water Hardness:
* Obtain a Water Hardness Test Kit:
You can purchase a water hardness test kit from a local hardware store or online. These kits typically contain test strips or a liquid reagent that can determine the hardness of your water.
* Collect a Water Sample:
Follow the instructions provided with the test kit to collect a water sample. This usually involves dipping a test strip into a sample of your tap water or using a specific container provided with the kit to collect a water sample.
* Perform the Test:
Use the test kit to perform the water hardness test according to the manufacturer's instructions. This typically involves adding the reagent to the water sample or dipping the test strip into the water.
* Read the Results:
Wait for the specified amount of time, and then compare the color change on the test strip or the reading from the liquid reagent to the reference chart provided in the test kit.
The chart will indicate the water hardness level in grains per gallon (gpg) or parts per million (ppm).
* Adjusting Water Hardness:
If the test reveals that your water hardness level is outside the recommended range for the Noritz EZTR40 or if you want to take preventive measures, you can consider the following options to adjust the water hardness:
Water Softener: Install a water softener in your home. A water softener uses ion-exchange resin beads to remove calcium and magnesium ions, which are responsible for water hardness. Softened water is generally easier on appliances, including tankless water heaters, as it reduces the likelihood of scale buildup.
Descaling: Regularly descale the Noritz EZTR40 to remove any scale buildup that may occur due to hard water. Descaling involves using a descaling solution to dissolve and remove mineral deposits from the heat exchanger and other components.
To descale, turn off the unit, isolate it from the water supply, and follow the manufacturer's instructions for flushing the unit with the descaling solution.
The frequency of descaling may vary based on water hardness, but it's generally recommended to perform this task annually or as needed.
Water Treatment Devices: Consider other water treatment devices or filters that can help reduce water hardness. These may include electronic water conditioners, catalytic water conditioners, or specific filters designed to address hardness.
Consult a Professional: If you are unsure about the best approach to adjust water hardness for your specific situation or if you encounter challenges, it's advisable to consult with a water treatment professional. They can assess your water quality and recommend suitable solutions.
Keep in mind that water hardness can vary significantly from one location to another, so it's essential to periodically test your water to ensure you are aware of the hardness level in your area. Adjusting water hardness is a proactive step to help maintain the efficiency and performance of your Noritz EZTR40 tankless water heater and extend its lifespan. Additionally, it can lead to energy savings by reducing the energy required to heat water in areas with extremely hard water.
