Defining Features
Through use of a homeothermic burner (patent acquired), our boilers deliver NOx emission values that drop substantially below the Tokyo Prefecture NOx emission standard of 60 ppm.

These boilers have a remarkably high heat efficiency rate of 105% due to their restricting as much as possible unnecessary heat exhaust and collecting latent heat in exhaust gas and then further increasing the water temperature. This means that fuel is conserved by up to as much as 30% when compared to predecessors.

As our boilers are once-through models, they are capable of bringing water to boil in as little as one minute after being switched on. Furthermore, they can be used with water head pressures of up to 20 m (0.196 MPa). They are also equipped with special thermostats that keep water warm at a regular temperature.

Our boilers can be installed for both indoor and outdoor use and have excellent durability against corrosion because of their stainless steel make.

These boilers can be turned on and off at the simple touch of a button, and are also operable by remote control.

We also stock many other hot-water boilers which can be used in various settings. These include once-through and storage-tank, outdoor and indoor, hot-water supply and spacial-heating types, in a host of different sizes. The latest edition of our boiler catalog is also readily available.
