General Features
MOMIJI
Momiji are the red maples typical of the East, whose leaves turn autumn red, a season the Japanese experience as a "comforting" season. Thanks to the mild climate and the returning temperatures (no longer the scorching heat of summer, not yet the freezing cold of winter), taking time out is even more enjoyable.
Enjoying your home, as well as the foliage, creates a sense of well-being. Momiji perfectly combines traditional systems with condensing technology.
In fact, while integrating perfectly with different systems, it is designed to optimize condensation technology on radiator systems, concretely responding to the savings and eco-sustainability needs of this type of heating, which is extremely widespread but often unable to fully exploit the benefits of condensation.
Heating is smart
Momiji offers a standard Wi-Fi chronothermostat (which can also be installed in a room other than the generator) to manage and control the boiler anytime, anywhere, in complete freedom.
Consumption reports, weekly programming, changing settings and managing multiple boilers (such as your own and that of your elderly parents, or that of your mountain home) from the same “My Rinnai” APP, available for Android and iOS smartphones.
All this and much more to offer you totally smart management.
The integrated climate probe is a standard feature of Rinnai heat generators: its internal positioning allows you, who uses it, and you, who installs it, to avoid masonry work and electrical connections.
Thanks to this sensor, you can forget about adjusting the temperature in your home and let the generator take care of everything, intelligently adjusting its operation based on the weather, whether cold or warm. So while the boiler operates in climate control with a sliding temperature, you can enjoy a perfect balance between comfort and savings, without any worries.
Momiji Comfort has never been so simple
Easy, everywhere
Like Rinnai Infinity water heaters, Momiji boilers are specifically designed to make the installer's job easier.
The device is small, lightweight and compact.
It's ready to use and doesn't require any configuration. The flue system is split Ø80/80 and, thanks to the fan's high head, it can reach up to 30 equivalent linear meters.
Heat exchange
Momiji features a copper heat exchanger with a large passage section: this facilitates integration into existing radiator systems and simplifies cleaning operations.
This range of boilers is the perfect solution for traditional systems that are often imperfect.
Can also be installed outdoors
Momiji is IPX5D certified and comes with a standard antifreeze kit down to -20°C. Thanks to these features, it can also be installed outdoors without the need for additional protection.
Integrated condensate neutralizer
The Momiji series features a condensate trap integrated into the generator, already filled with granulate and ready for use. This simplifies installation, even when replacing a traditional high-temperature generator.
The integrated neutralizer, in fact, allows you to eliminate the acidity of the condensation (water with an acidic pH produced by the normal operation of the heat generator, which is corrosive for the pipes) without having to face the costs of purchasing and maintaining an external accessory that performs this function, which would otherwise be indispensable.
