Gas boiler "Rinnay" - the products 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 produced by Rinnai are distinguished by worthy operational and technical characteristics, compactness and stylish design. The gas equipment of this company easily fits into the most stylish interiors without introducing a discord into their concept.
About company
Rinnai was founded in 1920. Its creators are Japanese entrepreneurs Rino and Naito. Sells equipment worldwide. The company's motto is “Absolute quality guarantees”. The manufactured devices use the latest developments, innovative technologies, digital and electronic control. Of the variety of products manufactured, the company sends only wall-mounted boilers to Russia. 300 thousand boilers are launched every year in the world - this is three times more than the whole Europe produces.
Design features
The main feature of Rinai boilers is their technical capabilities. Japanese equipment is designed to replace a person in matters of control and regulation - everything is done by automation. The air-gas mixture supplied to the burner is controlled by devices - 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 be hidden - gas suppliers often sin by the uneven pressure in gas pipelines. This is especially true in the 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.
Pros and cons
Gas is the most profitable fuel, that's why the heaters working 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 it worth blowing out the burner or the inability to ignite the wick. The Japanese boiler has many 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 the operation.
- Outward appeal.
- Simple construction. Installation usually does not raise questions. Management is intuitive - everyone will master. Reliable and durable.
- Can be repaired - any unit or element that is out of order must be replaced.
- "Independence" - it should be programmed once, and you can no longer interfere in its work.
- Service is minimal. For example, a smoke exhauster is installed in the RB-106 GMF - it prevents the formation of soot in the chimney.
- Adaptation to our conditions.
- The presence of an extensive service network.
But this is not all, the global advantages of Japanese technology are based on specific technical solutions:
- Self-diagnosis system of malfunctions.
- Work at a low pressure of water.
- 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 big step in adjusting the temperature - it is not always possible to set the desired value.
- The relatively high price is approximately 50,000 rubles.
- At low pressure, the device smokes - the efficiency drops.
- Can be installed for heating rooms from 100 sq. M.
- It is necessary to mount automation that tracks gas leaks.
- Installation is simple only for specialists - it is not recommended to install the equipment yourself.
How does gas equipment work?
Rinnay boilers are able to work on any gas - you can always play it safe 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 nitric oxide released during combustion. The characteristics are outstanding, and the device is brilliantly simple. Design Features:
- Case material - high-strength steel. Powder paint on top.
- All important elements are weatherproof - foam is used.
- Each model is equipped with automatic flame control.
Gas saving is 14%. Harmful emissions - a minimum. There is a fault diagnosis system.
Important! For uninterrupted operation of volatile devices and damping voltage drops in the network, an uninterruptible power supply is required. It is also possible to provide a stable voltage with a generator or battery.
What series are released?
Rinnai produces four series that differ in technical parameters - each of them is designed for specific operating conditions. All models are wall-mounted, dual-circuit. One is for heating, the second is for heating hot water. Thanks to the company's engineers ’own development, the equipment produced saves consumers 20% of gas when it switches 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 components. RMF Features:
- They are convenient to manage - the developers complemented the design with a color display and even added voice control.
- Installed automation that responds to weather conditions and regulates the temperature.
- The devices are volatile - connected to the mains, therefore, the developers have provided blocks that monitor the consumption of electricity, as well as taking measures to reduce it.
- Automatic control of water temperature in hot water mode, accuracy - up to a degree. Turning on occurs when water consumption is from 2.5 l / h, and when consuming 1.5 l / h, it turns off. Accuracy - 0.3 l / h. The function of operational consumption has also been added - all fuel is spent on heating the coolant in the secondary circuit - this ensures uninterrupted supply of hot water of a given temperature.
- For greater convenience, the manufacturer has provided a remote control that can answer in voice with questions.
- There is a programmer - for a certain time the operating mode is set.
- Novelty - 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 in capacities from 18,600 to 41,900 watts. The combustion chamber is closed. Water heating - flowing.
EMF
This is the simplest series that formed the basis of other models. But, despite the availability of more advanced versions, the EMF models remain a model of Japanese quality. The power range is 12,000-42,000 watts. Power adjustment for each device is within 25-100%. Forced ventilation is provided. There is a circulation pump with a magnetic coupling that prevents the motor from jamming. The control process is controlled by a microprocessor. The models in this series are manufactured by Korean factories belonging to the Rinnay concern.
GMF
This is the so-called "green series." The highest level of environmental friendliness. Specifications 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.

Having almost the same parameters, they differ in price - Korean products are cheaper. Their estimated cost is 26,000 - 76,000 rubles. “Rinnay” - 50,000-95,000 rubles. There is no big difference between the operation of the devices. “Koreans” have a fireproof coating on the heat exchanger. Navien is easier to maintain - users claim that its design is simpler.
Reviews
RB 257 EMF: Timofey Yu., Zhukovka
It works almost silently. The remote control is included in the kit - you do not have to spend an additional 4 thousand. It has been working 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 adjustments for a frosty climate - with a margin. Another minus - when lowering to minus 20, there are problems with the chimney, ice freezes and air enters the boiler poorly.
RB 366 EMF: Andrey Ts., Kirovsk
For a long time they used a single-circuit apparatus for heating. Bought "Rinnay" after the reviews of friends. Takes up little space - hanging on the wall. Beautiful design. It perfectly copes with the task - it heats our large house with an area of 350 squares. With the supply of hot water, there are no problems either. The heating temperature is adjusted depending on the weather.
Rinnai boilers are high-performance equipment that has been successfully used in residential and industrial premises. Replacing the nozzles, you can use liquefied fuel. Problems with trouble-free Japanese equipment occur mainly due to improper installation or violation of operating rules.
