The Rinnai gas boiler is a product of a Japanese company specializing in the production of heating equipment. Given the desire of the Japanese for impeccable quality, their penchant for minimalism, it is not surprising that the boilers manufactured by Rinnai are distinguished by decent performance, compactness and stylish design. The gas equipment of this company easily fits into the most stylish interiors without dissonance in their concept.
About Us
Rinnai was founded in 1920 by Japanese entrepreneurs Rino and Naito. Sells equipment worldwide. The motto of the company is “Absolute Quality Assurance”. The manufactured devices use the latest developments, innovative technologies, digital and electronic control. Of all the variety of products, the company sends only wall-mounted boilers to Russia. 300 thousand boilers are launched annually in the world – this is three times more than the whole of Europe produces.
Design features
The main feature of the Rinay boilers is their technical capabilities. Japanese technology is made in such a way as to replace a person in matters of control and adjustment – everything is done by automation. The air-gas mixture supplied to the burner is controlled by instruments – they monitor its composition and concentration so that the combustion effect is maximum. As a result, productivity and efficiency increase, and gas consumption decreases.
The operating mode is selected automatically – depending on the gas pressure in the pipes. What can we hide – gas suppliers often sin with uneven pressure in gas pipelines. This is especially true in winter. Using automation, the Japanese were able to eliminate the problem of pressure drops – regardless of its value, the device works, saves gas and creates a comfortable temperature in the house.
Advantages and disadvantages
Gas is the most profitable fuel, which is why heaters running on it are so popular. But domestic analogues and some foreign ones have several drawbacks, due to which their operation becomes uncomfortable, causes a lot of trouble and even annoys. What is worth blowing out the burner or the inability to light the wick. The Japanese boiler has a lot of advantages that make it extremely attractive for owners of private houses and apartments:
- Small size and weight.
- Economical fuel consumption – Rinnai costs about twice as much as Luch or Signal, but you will pay less for gas, and there will be no problems with operation.
- External attractiveness.
- Simple construction. Installation usually does not cause problems. Management is intuitive – everyone will master it. Reliable and durable.
- Repairable – any component or element that is out of order must be replaced.
- “Independence” – it is worth programming it once, and you can no longer interfere with its work.
- Service is minimal. For example, in the RB-106 GMF model, a smoke exhauster is installed – it prevents the formation of soot in the chimney.
- adaptation to our conditions.
- Existence of an extensive service network.
But that’s not all, the global advantages of Japanese technology are based on specific technical solutions:
- System of self-diagnostics of malfunctions.
- Operation at low water pressure.
- Control and adjustment of flame intensity.
- Protection system for the control unit.
Disadvantages
There are disadvantages, but they are not significant compared to the above advantages:
- A large temperature adjustment step – it is not always possible to set the desired value.
- Relatively high price – approximately 50 rubles.
- At low pressure, the device smokes – the efficiency drops.
- Can be installed for space heating from 100 sq.m.
- It is necessary to mount automation that monitors gas leaks.
- Installation is simple only for specialists – it is not recommended to install the equipment yourself.
How does gas equipment work?
Boilers “Rinnay” are able to work on any gas – you can always make sure in case of an accident on the gas pipeline. Heat is generated by burning fuel. Special burners are used – their design allows to reduce the amount of nitrogen oxide released during combustion. The features are outstanding and the device is ingeniously simple. Design features:
- Case material – high-strength steel. Top is powder coated.
- All important elements are protected from weathering – foam filling is used.
- Each model is equipped with automatic flame control.
Saving gas is 14%. Harmful emissions – a minimum. There is a troubleshooting system.
Important! For uninterrupted operation of volatile devices and suppression of voltage surges in the network, an uninterruptible power supply is required. You can also provide a stable voltage using a generator or battery.
What series have been released?
Rinnai produces four series, differing in technical parameters – each of them is designed for certain operating conditions. All models are wall-mounted, double-circuit. One – for heating, the second – for heating hot water. Thanks to the company’s own developments, the manufactured equipment saves consumers 20% of gas when it is switched to hot water mode.
RMF
The series appeared in 2013. The previously released EMF series became the basis for its creation – it was improved by adding several innovative automation units. RMF Features:
- They are convenient to manage – the developers have supplemented the design with a color display and even added voice control.
- Automatic equipment is installed that reacts to weather conditions and regulates the temperature.
- The devices are volatile – connected to the mains, so the developers have provided blocks that monitor electricity consumption, as well as taking measures to reduce it.
- Automatic control of water temperature in DHW mode, accuracy – up to a degree. Switching on occurs when water consumption is from 2,5 l/h, and when it is consumed 1,5 l/h, it turns off. The error is 0,3 l/h. The function of operational consumption has also been added – all the fuel goes to heat the coolant in the secondary circuit – this ensures an uninterrupted supply of hot water at a given temperature.
- For greater convenience, the manufacturer has provided a remote control that can answer questions by voice.
- There is a programmer – the operating mode is set for a certain time.
- A novelty is a block that controls and corrects the intensity of the flame. A uniform distribution of fire over the burner is achieved – regardless of the pressure in the gas pipeline.
RMF boilers are available with power from 18 to 600 W. The combustion chamber is closed. Water heating – flowing.
ЕMF
This is the simplest series that formed the basis of other models. But, despite the presence of more advanced versions, EMF models remain a model of Japanese quality. Power range – 12-000 watts. Power adjustment for each device – within 42-000%. Forced ventilation provided. There is a circulation pump with a magnetic clutch that prevents the motor from jamming. The control process is controlled by a microprocessor. Models of this series are made by Korean factories belonging to the Rinnai concern.
FMG
This is the so-called “green series”. The highest level of environmental friendliness. Technical characteristics are similar to the EMF series. Carbon monoxide emissions are reduced to a minimum. A uniform supply of a combustible mixture of air and gas, measured by automation in exact proportions, is ensured. Burner flame adjustment. Power range 12-42 kW.
SMF
For heating 100-400 sq. m. Two heat exchangers. Development of the secondary – 14 l / min. The gas-air mixture is smoothly regulated thanks to the turbocharged burner. Minimal emissions make it possible to virtually eliminate the formation of scale and soot. 18-42 kW.

Consumers like to compare products with similar features. That is why Japanese and Korean boilers are so often compared – Rinnai and Navien, respectively. Having almost the same parameters, they differ in price – Korean products are cheaper. Their estimated cost is 26 – 000 rubles. “Rinnay” – 76-000 rubles. There is no big difference between the devices. The “Koreans” have a refractory coating on the heat exchanger. “Navien” is easier to maintain – users claim that its design is simpler.
Reviews
RB 257 EMF: Timofey Yu., Zhukovka
Works almost silently. The remote control is included in the kit – you do not have to spend an additional 4 thousand. Works for six months without any problems. There is a nuance – it takes air only from a warm room – otherwise the device fills with condensate. It is better to take power, taking into account the correction for a frosty climate – with a margin. Another minus – when it drops to minus 20, there are problems with the chimney, ice freezes and air does not enter the boiler.
RB 366 EMF: Andrey Ts., Kirovsk
For a long time, a single-circuit apparatus was used for heating. Bought “Rinnay” after the reviews of friends. Takes up little space – hangs on the wall. Beautiful design. It copes with the task perfectly – it heats our large house with an area of 350 squares. There are no problems with the supply of hot water either. The heating temperature is adjusted according to the weather.
Boilers of the Rinnai brand are high-performance equipment that is successfully used in residential and industrial premises. By replacing the injectors, liquefied fuel can be used. Problems with trouble-free Japanese technology occur mainly due to improper installation or violations of operating rules.
