Noritz Tankless Water Heaters

Yom Tov are days of celebration on which certain activities are prohibited, such as starting a new fire and refraining from working. If you have a tankless water heater, which creates a flame to heat water on demand, you may wonder if you can use it during Yom Tov. Thanks to recirculation pumps and lines, you can maintain hot water usage while observing Yom Tov.

The instructions for setting up your tankless water heater’s recirculation settings vary from manufacturer to manufacturer. In this article, we’ll show you how to prepare your Noritz tankless water heater so that your home has hot water available and complies with the traditions of Yom Tov.

At Monkey Wrench, our technicians receive specialized training with the top brands in tankless water heaters, such as Noritz. Since 2007, we’ve installed and serviced tankless water heaters throughout Los Angeles and the surrounding areas. For over 15 years, we’ve built special relationships with homeowners who observe Yom Tov but are unsure how to access hot water from their Noritz tankless water heaters.

Let’s get started!

 

Steps to Prepare My Noritz Tankless Water Heater for Yom Tov

Before we proceed with the instructions, we’ll divide them into two categories: Noritz tankless water heaters with external or internal recirculation pumps. 

Recirculation lines help cut down the time it takes for hot water to reach a fixture in your home by circulating hot water throughout your home’s water lines. Whenever you turn on a hot water faucet in your home, it sets off the flow sensor in your tankless water heater. It will then create a flame on demand and heat water as it passes through. 

Because it creates a flame each time hot water is needed, it does not comply in observance with Yom Tov. Recirculation lines bypass the need to create a flame by keeping water warm and available for use with the following benefits.

  • Reduce the wait time for hot water
  • Improve energy efficiency
  • Reduces water waste
  • Complies with Yom Tov

In the next section, we’ll first review how to easily set up your Noritz tankless water heaters with external heat pumps.

 

Setting Up Noritz Tankless Water Heaters With External Recirculation Pumps

The instructions for setting up your Noritz tankless water heater with a recirculation pump are simple. 

Before Yom Tov:

  1. Go to your tankless water heater and locate the external recirculation pump.
  2. Locate the timer on the pump.
    • Not all recirculation pumps look the same, but they should all have a timer.
  3. The timer is usually set to “auto” or “timer.”
  4. You can switch the pump’s setting from “auto” or “timer” to the “ON” position.

After Yom Tov:

  1. Go to your tankless water heater’s recirculation pump timer.
  2. Switch the setting from the “ON” position and put it back to “timer” or “auto.”

These instructions apply to any Noritz tankless water heater model with an external recirculation line pump. This accessory isn’t included with most Noritz tankless water heater installations. Check out our tankless water heater installation page for more information on scheduling an appointment to install a recirculation pump. 

Noritz offers an external recirculation pump accessory, but it also offers the NRCR tankless water heater series, designed with a built-in recirculation pump. The NRCR has instructions for Yom Tov preparation, which we’ll go over in the next section. 

 

Setting Up Noritz Tankless Water Heaters With Internal Recirculation Pumps

The Noritz NRCR111 and NRCR92 are tankless water heaters with internal recirculation pumps. These two units have their own instructions for the recirculation settings in preparation for Yom Tov. 

The settings depend on which remote controller you have for the unit. It’s important to note that neither of these remote controllers is included in a standard installation, but Noritz offers them as additional accessories.

The two remote controllers are the RC-9018 and the RC-7651. If you need help determining which one you have, look for the model number on the front side of the controller. 

 

Instructions for Setting Up the RC-9018 for Yom Tov

Follow the instructions below for setting up the timer on your Noritz tankless water heater using the RC-9018.

Before Yom Tov:

  1. Press the “ON/OFF” button to turn the remote controller on. The green light near the button should light up.
  2. Open the panel underneath the screen and press the “MENU” button. 
  3. Use the arrow keys to go to the “Recirc menu” and press the “ENTER” button.
  4. The next screen should display a “recirc operating on/off.”
  5. Press the “ENTER” button to set the recirculation pump always on.
    • The display screen should now display the following symbol: 🔁

After Yom Tov:

  1. Go to your remote controller and press the “ON/OFF” button.
  2. Open the panel underneath the screen and press the “MENU” button. 
  3. Use the arrow keys to go to the “Recirc menu” and press the “ENTER” button.
  4. From here, you can turn the recirculation mode off or select “recirc menu” to set a timer on the recirculation to kick off at set times, depending on hot water usage. 

If you encounter any issues or have any difficulties setting up the timer, it’s recommended that you contact a technician for further assistance. For homeowners who don’t have the RC-9018, the next section covers instructions on setting up the RC-7651 for Yom Tov.

 

Instructions for Setting Up the RC-7651 for Yom Tov

If your NRCR tankless water heater has an RC-7651, the instructions for setting up the recirculation mode are different. Here’s a step-by-step process for setting the recirculation mode to always on to comply with Yom Tov. You can also watch a video with instructions directly from Noritz as well. 

Before Yom Tov:

  1. Press the “POWER” button to turn the remote control off.
  2. Unplug your Noritz tankless water heater for approximately 10 seconds, then plug it back in.
  3. Press the down arrow button on the remote control and it will show the number “99” flashing. 
  4. Press the up arrow button several times until you reach “22.”
    • Make sure the “priority” light on the screen isn’t flashing.
  5. Press the up arrow button one more time to show the number “23,” and then press and hold the “SETTINGS” button until you see the priority light flashing. 
  6. Press the up arrow button to display the number “24” on the screen and ensure the priority light is no longer flashing.
  7. Press the arrow button a couple of times until you see “3b” appear on the display.
  8. Press and hold the up and down arrow buttons at the same time to save the setting. The display will go blank, and the remote controller will beep a few times. 
  9. After 10 seconds, turn the remote controller on with the “POWER” button. The NRCR recirculation is now set to always on. 

After Yom Tov:

The steps for setting the recirculation mode on your Noritz NRCR tankless water heater back to default are the same as turning it to always on. After following the instructions, the recirculation mode should be set back to default. 

 

Now Your Noritz Tankless Water Heater Is Ready for Yom Tov
