Overview of heating gas boilers Rinnai

Peculiarities

Rinnai is one of the most famous Japanese corporations producing high-level equipment at affordable prices. She appeared back in 1920. In the process of producing their products, the concern's specialists use the most interesting author's ideas and the latest technologies, which allows them to create the most productive and economical devices for heating systems.

Characteristic features of devices from the eminent Japanese brand:

• heat exchangers are made of high quality copper;
• high environmental parameters;
• the ability to control the unit remotely from a mobile phone;
• convenient control panels;
• compact dimensions;
• efficient performance even at a reduced level of gas pressure;
• regulation of the fuel combustion process;
• increased efficiency;
• quiet operation and no vibration.

Any product from the brand Rinnai will be distinguished by excellent functionality, 100% reliability, simplified management. If there is a sudden power failure or a low fuel pressure level, the sensor of the device will immediately alert about this, and the device will automatically switch to economy mode to avoid subsequent problems.

Products from Rinnai can easily operate on any type of gas - it does not matter if it is natural or liquefied. Heat will be generated by burning gas through burners of a special technical design, which will generate a small amount of nitrogen oxide during their operation.

At the same time, consumers should be aware that despite the fact that Japanese units have the most outstanding characteristics, their device and operation are quite simple. The body of the product is made of durable steel, which is coated with a special powder paint. The main elements of the devices are protected from various impacts by foam filling. All popular models of the manufacturer have an automatic flame adjustment system.

Rules for safe operation

Any gas boiler is used for the processing of fuel that is dangerous to the life and health of consumers in the event of its leakage, the release of its utilization products and the leakage of the coolant heated by it.

Boilers of the Japanese manufacturer Rinnai are known for their highest reliability and excellent performance. Basically, factory defects are extremely rare on these devices and technical errors are associated with improper operation and untimely preventive inspections.

All work on the repair and replacement of gas-using equipment should be carried out by specialists from the service department or GRO. Otherwise, you may be threatened with shutting off the gas supply at best, and at worst - a threat to health and life.

Moreover, the cost of such devices, especially from well-known manufacturers, is not always budgetary, and the warranty is long. An intrusion into the gas boiler system can be regarded as a violation of the warranty immunity and, accordingly, it is not worth waiting for free repair and replacement of individual elements from the service department.

But again, it is quite possible to eliminate some points in boiler malfunctions on your own, or knowing them, you can determine what work to call the master and ask how much the repair will cost.

Rinnay boiler series

4 series of equipment designed to work under certain conditions

Each series is produced to work in certain conditions. All types of Rinnai boilers from the Japanese manufacturer have similar technical properties, the difference lies in the complexity of the control systems and the power of the units.

The best and most famous models features and prices

The range of Rinnai wall-mounted gas boilers is quite wide and varied. There are models designed for heating rooms of different sizes. They differ in performance, set of built-in functions and price. Therefore, when choosing a boiler, it is necessary to understand exactly for what purposes it will be used. Below are descriptions of some of the popular models of Rinnai gas equipment.

rb 167 rmf

This model is suitable for use in heating systems for houses up to 180 square meters. m. This boiler is characterized by low noise and stable operation. With not the highest efficiency, the rb 167 rmf model is one of the most economical units in its price category. Additional features include the presence of a remote control and the possibility of synchronizing it with a smartphone via a wireless interface. Which is a rarity for budget models.

rb 167 emf

This boiler is the forerunner of the model described above. It has less functionality, but it is much cheaper. The kit also has a remote control, but there is no way to control the operation of the boiler from a mobile device. There is also no function of long-term programming of the device operation. The main differences of this model are greater efficiency and higher efficiency than the next generation model.

rb 207 rmf br r24

One of the most popular models of gas boilers manufactured by Rinnai. This boiler has more power and is able to effectively heat a room up to 230 square meters. m. Like most models of the brand, the boiler is equipped with a remote control, which greatly simplifies the control of the device. It is possible to program the operating modes of the boiler for several days. The ratio of fuel consumption and performance is considered close to optimal. The design of the boiler provides protection against freezing and overheating.

br ue30

More powerful, efficient, but at the same time an expensive model. The efficiency of the br ue30 boiler exceeds 91%, which is close to the efficiency of boilers from leading European manufacturers. The design of the boiler ensures complete combustion of fuel at any level of installed power.Smooth power adjustment is possible in the range from 25% to 100%. The presence of an additional protective casing ensures almost silent operation of the device. The disadvantages of this model include the lack of an additional circuit for circulating hot water in the water supply system.

rb 277 cmf

One of the most efficient and high-tech boilers on the world market. Rinnai's unique developments allow the device to provide over 104% efficiency. With a maximum power of almost 30 kW, gas consumption is only 1.84 cubic meters. m/hour. The device provides these parameters without failures. In addition, this model meets all modern parameters of environmental friendliness.

The best and most famous models: features and prices

RB-167RMF

One of the best Rinnai boilers for heating a private house with an area of ​​150-180 m2 (power 18.6 kW). It features high reliability, stability and quiet operation. The boiler efficiency is optimal, but not high - 85.3%, but at the same time the unit has one of the lowest gas consumption indicators in the price category - 2.05 cubic meters. m/hour. The principle of operation is convection, wall mounting, closed combustion chamber.

A special advantage in this price category is the presence of a remote control in the kit, it is also a room thermostat that allows you to control the operation of the boiler and adjust the temperature not only from another room, but also from a smartphone (if Wi-Fi is available). The hot water supply is stable, even with a large constant consumption, the burner copes with low gas pressure. The average cost is 49,000 rubles.

RB-167EMF

An earlier version of the RB-167 RMF described above.With an equal power of 18.6 kW, it differs, oddly enough, in a higher efficiency - 88.2%, and an even lower gas consumption - 1.83 cubic meters. m/hour. Everything still has a remote control in the kit, but with less functionality: there is no possibility of programming the operating mode for a week ahead, weather-dependent mode, etc.

There is also no frost protection, not so modern design of both the boiler and the room thermostat. Accordingly, the cost of the boiler is lower - an average of 39,000 rubles.

RB-207 RMF (BR-R24)

The most famous and increasingly gaining popularity due to the successful operation of the model. The boiler is designed for an area of ​​​​up to 230 square meters. m., has a second circuit for hot water supply and an optimal efficiency of 86.3%. Equipped with overheating protection, frost prevention mode, programmer.

In fact, it is not much different from the RB-167 RMF and is its more powerful and efficient version, it is better to choose if the area of ​​\u200b\u200bthe house exceeds 160 m2. Cost - 52,000 rubles.

BR-UE30

Gas wall-mounted single-circuit boiler with a built-in three-way valve and the ability to connect an indirect heating boiler. The main difference is the high efficiency of 91.8%, comparable with the reference German models, gas consumption at a power of 29 kW - 2.87 cubic meters. m/hour.

The device of the heating boiler consists of a copper heat exchanger and turbocharged burners, which make it possible to smoothly modulate the boiler power (from 25 to 100%) and maintain complete combustion, due to which a high efficiency is achieved. The body is equipped with additional noise insulation, making the operation of the boiler very quiet.

Among the shortcomings - the lack of a secondary circuit for hot water supply and a higher cost - an average of 56 thousand rubles.

RB-277 CMF

The most technologically advanced, efficient and environmentally friendly double-circuit condensing model.With a thermal power of 29.7 kW, the manufacturer managed to achieve 104.6% efficiency and gas consumption of only 1.84 cubic meters. m / h, which only a few models on the market can boast of. Due to efficient combustion, the boiler meets the highest environmental standards, carbon monoxide and nitrogen emissions are reduced to safe standards (NOx - 22-26 ppm). The maximum temperature of the heat carrier is standard - 40-85°C, which allows reaching 5-40°C in a heated room.

To prevent the well-known error 99, there is a function for fine adjustment of the exhaust fan (R.P.M), however, it is still recommended to take care of installing the chimney at an angle and insulating it.

In practice, with such high performance, the boiler operates smoothly and without problems, serious malfunctions were registered only in cases of violations of the operating rules (lack of annual maintenance, air in the heating system). Cost - 74,000 rubles.

The device of Rinnai gas boilers

A typical device of double-circuit devices of this company, for all its functionality, is quite simple. If you are at least a little versed in the design of heating boilers, it will not be difficult for you to find one or another element for diagnosing it.

So, 2 branches depart from the upper part of the device case. One pipe is exhaust, and the second is air intake. Both elements go to the coaxial type chimney. Accordingly, both oxygen intake for combustion and the removal of combustion products take place through it.

2 pipes also come out of the lower part - gas and water supply.

There is nothing superfluous in gas boilers of this Japanese company. Simple, yet reliable device and high quality parts, and the availability of spare parts in stores, provide an easy repair

The closed type combustion chamber has a three-stage type burner.

Above the nozzle is the main heat exchanger with copper plates. The secondary, consisting of copper and stainless plates, is located below, it is used to heat the hot water supply system, and a three-way valve is connected to it.

At the top is an expansion tank, and at the bottom is a circulation pump, which usually works universally for open and sealed systems.

And now the most interesting. This is a remote control with a display. Thanks to this technological device, the temperature regime is adjusted both for heating and for hot water supply. In addition, self-diagnosis indicators are displayed on its high-contrast display.

How is the error output?

As already mentioned, the error identification occurs with the display of the remote control panel.

The first and second digits are the error code. For example, 16. The third digit (stands with a space from the first two) is the power of the boiler.

Denoted by numbers from 2 to 6, and read something like this:

• 2 = 167;
• 3 = 207;
• 4 = 257;
• 5 = 307;
• 6 = 367.

And the last, fourth digit, the type of chimney: 2 - ME, 3 - MF.

If an error occurs on the display with a characteristic sound signal, you must immediately start troubleshooting. It is strongly not recommended to repeatedly try to start the boiler again, no matter what the digital indicator is. A single reboot is usually enough to rule out a temporary failure of the control module.

In the event of a malfunction, the remote control starts signaling (beeping) to the owner about difficulties in the system and displays an error code on the screen.

We will now consider the most common errors of the RB RMF series devices, but we will start with prevention so that you encounter such problems less often.

Troubleshooting and preventative diagnostics

If you have any problems with your Rinnai heating and DHW boilers or want to check the operation of this system, you will need to perform a few diagnostic steps.

Here is a brief overview of the general work involved in this procedure:

It is necessary to inspect the gas valve - GSA VALVE and the state of its operability

Usually, with such problems, error 11 is displayed.
Check the opening status of electronic valves 1 and 2.
Measure the voltage at the piezo source (AC 220V).
Pay attention to the connection of the proportional valve. This produces error 52

Another valve to look at is for warm water. By the way, its minimum working amount is approximately 1.7 l / min and this parameter is also recommended to be checked.

Diagnostics of the gas boiler operation system is the prerogative of the masters from the service organization. If a malfunction is suspected or during preventive maintenance, a complete inspection and control of the operation of each element is carried out.

In Errors 15 and 16, we will look at boil and overheat faults.

To diagnose these problems, you need to:

inspect for operability of the electronic valve and for water supply

Their operating voltage is 220 volts, when stopped it is zero;
pay attention to the pump. It can stop due to pollution, also in the case of this element, a breakdown of the relay and the contact of the capacitor wires can be considered;
check the heat exchanger for blockages and flush it if necessary;
in the event of a sudden increase in temperature, pay attention for a faulty thermistor.

It should be noted that these recommendations do not apply to those owners of boilers who have a very poor understanding of the design and principles of operation of gas-using equipment.

And now we will analyze the most common error codes and options for their elimination.

Advantages and disadvantages

The equipment has a program of additional savings and a multi-level protective system (10 degrees). The Renay boiler is produced with an original design, it is controlled simply, using a remote control. The unit provides a uniform, stable temperature of hot water, the degree of heating of the energy carrier is regulated by the environment. It has a long life without changing the efficiency, thanks to quality control at release and an effective control unit in the boiler.

The disadvantages include a large step on the temperature adjustment scale, which sometimes does not allow you to set the required value.

“The boilers from the Rinnai company are considered one of the best and most modernized, so I decided to buy an EMF RB-107 series appliance for an apartment. It has a reasonable price, excellent technical characteristics. Despite the fact that it heats the premises and supplies hot water, the savings are significant. Thanks to the many sensors, it is possible to correct the work even at low pressure. Automation protects equipment from freezing and overheating. For 5 years of operation, I had to contact the service department for repair once.Incorrect coding of the control system led to a failure. After debugging, this Rinnai model functions perfectly.”

Sergey, St. Petersburg.

“We decided to buy Rinnai equipment, taking advantage of the positive feedback from our friends. They installed a boiler in the house three years ago, we purchased last winter. Excellent design, smooth operation, fine adjustment system - a small list of advantages of the unit. It does a good job of heating the building and supplying hot water. Adjusts the temperature depending on the climatic conditions. With proper handling and maintenance, there are no problems with the operation of Rinnai equipment. Our brand is GMF RB-366.”

Valentine, Moscow.

“We have been using a boiler from the Japanese manufacturer Rinnai for two years now. Installed model SMF RB-266 for heating and hot water. The house is always warm in winter, and the device independently regulates the temperature, depending on weather conditions, so that it is not too hot or cold. DHW is supplied almost instantly, thanks to periodic heating. You can control it remotely, as there is a remote control, it is also convenient to set the program in case of a long absence of family members. For us, the advantage is the fact that there is no need to install a traditional chimney, we managed with a coaxial pipe. It doesn't make any difference."

Mark, Almaty.

The lineup

Currently, the Japanese company offers several models that are divided into series:

• RMF;
• EMF;
• G.M.F.

How do they differ from each other? Of course, quality characteristics and additional functions.

Green Series Features

RMF series boilers

Let's start with the fact that this series was released in 2013, that is, quite recently. Their designs were based on the EMF series boilers, but they were improved through the use of the latest automation devices. What underlies the novelties of this series:

• First of all, the developers have introduced the convenience of its operation into the design of the device. For this, a control panel with a color screen was installed, voice control appeared.
• Weather-dependent automatic control and regulation of temperature was installed.
• Since these are volatile gas boilers, special blocks have been installed in them that monitor the consumption of electricity and, as far as possible, reduce its consumption.
• Since all Rinnai gas boilers are double-circuit wall-mounted units, the company's engineers developed schemes and devices for operating the device, which helped save gas consumption by 20% when the boiler switched the fuel supply to the DHW system.
• Installation of automation that monitors the operation of the unit in the mode of hot water supply. That is, the mode is as follows: the heater turns on when the hot water consumption starts from 2.5 l / h, and turns off when the consumption is 1.5 l / h. There is a small error here - 0.3 l / h. The designers also added a quick consumption feature. In this case, all gas is redirected to heating the secondary coolant.
• As an addition to ease of use, the company offers a remote control that can answer your voice requests.
• Installed programmer.
• A novelty is used, which was developed and patented by the specialists of the RINNAY company. This is a special unit that controls and regulates the size of the flame on the burners. This allows you to evenly distribute the fire throughout the burner, regardless of the gas pressure in the pipeline.

Note that this series offers boilers with a capacity of 18.6 kW to 41.9 kW. This model uses a closed combustion chamber, a flow mode for heating hot water.

EMF

This is a simpler model, which is the basis of other series. But even boilers from this series are of high Japanese quality.

• Power within: 12-42 kW.
• The ability to regulate each model in terms of power in the range of 25-100%.
• Installed fan with different modes of rotation of the blades.
• Built-in circulation pump, which has no glands and has a special magnetic coupling that prevents the pump from jamming.
• The whole boiler control process is looped on the microprocessor.

Gas boilers of this series are today produced at the company's factories, which are located in South Korea.

Rinnay boilers from the green series

GMF

Wall-mounted gas boilers "Rinnay" of the GMF series are representatives of the "green series". The environmental friendliness of this model is at the highest level. According to all their technical characteristics, they exactly repeat the EMF series.

But, as mentioned above, the environmental friendliness of these boilers is their distinguishing feature. Let's just say that carbon monoxide emissions, especially nitrogen dioxide, are reduced to the lowest levels.No other boilers from different manufacturers can boast of this. We add that this type of boilers combustion of gas ensures its uniform supply to the burner and precise mixing of air and gas into one combustible mixture.

And another important distinguishing feature is the remote control of the coolant temperature. This is not the case for other models.
