Book NowIf you’re reading this, then chances are you’ve gone to turn on the shower on a cold morning only for the hot water to peter out and leave you wanting a bit more heat. While the easiest solution would be to adjust your tankless water heater temperature, it isn’t always advisable.
We know how important a hot shower can be to get your day going, and after 20 years of servicing tankless water heaters, we can tell you that sometimes the simplest solution isn’t the best, and that goes for upping your water temperature.
In this article, we’ll walk you through how to adjust the water temperature on your Noritz tankless water heater but also touch on why you likely won’t want to follow through.
Let’s jump right in with the steps you can take to adjust your water temperature on a Noritz tankless water heater.
How to Adjust Temperature on Noritz Tankless Water Heaters
Adjusting the water temperature on your Noritz tankless water heater is a breeze. While the process is easy, it may not be the best solution to your problem, though.
There are two ways to adjust the temperature on Noritz tankless water heaters: with a remote and without a remote. Let’s touch on how to adjust the temperature with a remote first.
- Turn off the tankless water heater.
- Press and hold the flow alarm key for approximately two seconds until a beep sounds.
- The temperature will blink on the display.
- Adjust the temperature in five-degree increments using the up and down buttons.
- Once you’ve set your ideal temperature, turn the unit back on.
- Unplug the tankless water heater from its power source.
- Remove the four screws holding the front panel in place.
- Remove the front panel.
- Use the labeled dip switches to set the temperature of your tankless water heater.
- Once you’ve set your tankless water heater’s temperature, you can pop on the front panel using the four screws you previously removed.
And that’s it. There’s nothing else to it.
Adjusting Your Noritz Tankless Water Heater Water Temperature isn’t Always Safe
Noritz tankless water heaters ship with a stock water temperature of 120 degrees and can adjust up to 140 degrees. So, any five-degree increment within that range is fair game.
Before you adjust your water temperature, it’s important to know that anything above 125 degrees may cause burns due to scalding. Noritz warns of this danger in its manuals.
If you adjust the water temperature above 125 degrees, the display will flash, and you’ll hear a tone coming from the tankless water heater. Use caution when adjusting your water temperature, especially if there are children or elderly persons in your household, as they are more susceptible to scalding.
If bringing your water temperature up five degrees yields no difference, then there may be other issues. Improper or infrequent maintenance can result in tankless water heaters not performing as well as they did out of the box.
Call a technician to schedule a check-up if your tankless water heater temperature isn’t up to snuff.
Additionally, by raising the temperature, you run the risk of earlier breakdowns, putting more stress on the heat exchanger, and lowering water pressure. Once again, use caution when adjusting your water temperature.
