★Maintenance Information★
Please check the Noritz website for maintenance information regarding the Wakasu App.


Convenient and tailored to each individual's lifestyle.

●Remote Control
You can operate your water heater with your smartphone.

When you want to take a bath immediately after returning home from leisure activities or dropping off your children at lessons, you can remotely operate the water filling function from outside the home.

Also, even if you forget to set the bath's temperature retention or turn off the underfloor heating, you can operate it from outside the home, or even from your bed before going to sleep at night.

You can connect to and operate the bath from anywhere without having to go near the remote control, reducing the burden of housework.

●Monitoring Function
You can see the status of the bathroom, so you can check on your family's bathing status even when you are out, providing peace of mind.

To address the issue of extended bathing times among family members living together, the app displays the bathing status and sounds an alarm on your smartphone when the set bathing time has elapsed.
You can also call the bathroom remote control from the app.

Furthermore, you can check the "hot water usage status" of family members living separately using the app.
The app will notify you of hot water usage the next morning, providing peace of mind even when you're far away.
*Available functions may vary depending on the equipment installation.
*You will need to install a water heater and remote control compatible with this app at the home of your family member living separately, and connect your smartphone.

●Error Confirmation Screen
Even in the event of a sudden water heater malfunction or error, you can use the app for peace of mind.
The cause of the error is immediately clear, and you can inquire, request maintenance, or repairs on the spot.

＜Enjoying Bath Time＞
Discover new ways to enjoy bathing and learn new knowledge, expanding the enjoyment of your daily bath time.

● Voice Customization Feature "Bath Encyclopedia"
Customize the bath filling completion voice and have your favorite animal character announce when the bath is ready.
"Bath Encyclopedia" is full of unique animals who love baths. New characters voiced by popular voice actors may appear for a limited time.
Change to your favorite character and enjoy bath time even more!

● Voice Customization Feature "My Voice"
"My Voice" allows you to record your favorite voice, such as your child's voice, and use it as the "one-of-a-kind" bath filling announcement voice for your kitchen remote. You can even record the voices of family members living far away to feel closer to them.
Set "My Voice" and enjoy a fun bath!
*The "My Voice" function is only compatible with the "RC-K100W series" remote.

● Warm Sleep Support Mode
Set your planned bedtime in the app, and the app will notify you of the recommended bath start time. Furthermore, by recommending a suitable time to leave the bath based on your bath temperature setting and bathroom temperature, it supports your bedtime bathing routine.
*Turning off your smartphone will cancel the bedtime setting for "Warm Sleep Support Mode."


You can check your bathing habits at home using data.
You can check the amount of hot water used, bathroom temperature, etc., by time of day, day, and month, and reviewing your usage can help you save water.
