About the manufacturer

Founded in 1920, the company Rinnai has been producing and marketing heating equipment, such as water heaters, gas boilers, pipes, and chimneys, for over a decade. The gas boiler units’ quality is comparable to that of the top German producers, although the main brand models are between 10 and 30 percent less expensive.

The company has been selling its products through dealer networks in the Russian market for over a decade. established itself as a producer of boiler units with superior operational and technical qualities, resource economy, and 24/7 exceptional service. Installers take note of how simple it is to maintain and install.

In 98% of cases, the only automation errors that cause malfunctions are error 99, for example, which can happen when the boiler is not serviced completely or promptly. Less frequently, icing of the chimney occurs when the temperature drops to -15°C or below.

A voltage stabilizer is another essential piece of equipment in the boiler room; without one, Rinnai gas boilers are susceptible to voltage swings, which can quickly cause the electrical board to fail.

There are no complaints regarding this brand’s boilers in accordance with installation and operation guidelines, and the units typically function flawlessly for more than 8 to 10 years.

Reviews of owners about gas boilers Rinnai: advantages and disadvantages

The best and most famous models: characteristics and prices

RB-167 RMF

One of the greatest Rinnai boilers (18,6 kW) for heating a private home between 150 and 180 m³. Highly reliable, stable and quiet operation. With a boiler efficiency of 85.3%, which is optimal but not particularly high, the unit has one of the lowest gas consumption rates in its price range at 2,05 cubic meters per hour. Mechanism of operation: convection; wall mounting; closed combustion chamber.

The presence of a room thermostat, also known as a remote control, in this price range is particularly advantageous since it enables you to control the boiler and adjust the temperature not only from another room but also from a smartphone (if Wi-Fi enabled). Consistent hot water supply: The burner can withstand low gas pressure even with high continuous consumption.

Gives an error (error 99) when the chimney freezes, similar to many boilers. Installing a coaxial chimney at an angle (2–3°) can solve the problem. After five years of installation experience, no additional significant drawbacks have been found.

RB-167 EMF

An earlier iteration of the previously mentioned RB-167 RMF model. It is notable for having an even lower gas consumption of 1.83 cubic meters per hour and an even higher efficiency of 88.2%, despite having an equal power of 18.6 kW. There is a remote control included as well, but it has limited functionality. For example, you cannot program the operating mode to run for a week in advance or switch to weather-dependent mode.

The boiler and room thermostat are not designed in a modern manner, and there is no protection against frost. As a result, the boiler is less expensive.

RB-207 RMF (BR-R24)

The most well-known and rising in popularity as a result of the model’s effective operation. The boiler has an optimal efficiency of 86.3%, a second circuit for domestic hot water, and is designed to fit in an area up to 230 square meters. featuring a programmer, a frost prevention mode, and an overheating protection feature.

Is essentially the more potent and efficient version of the RB-167 RMF, and it is best to select it if the house is larger than 160 m³.

BR-UE30

Wall-mounted gas single-circuit boiler with an indirect boiler connection option and an integrated three-way valve. The primary distinction is a high gas consumption of 29 kW, or 2.87 cubic meters of gas per hour, which is comparable to the reference German models’ efficiency of 91.8%.

The heating boiler’s device, which includes burners with turbocharging and a copper heat exchanger, enables smooth modulation of the boiler output (from 25 to 100%) and maintains complete combustion, which is how the high efficiency is attained. Because of the extra noise insulation in the case, the boiler operates very quietly.

The lack of a second circuit for DHW and increased cost are the drawbacks.

RB-277 CMF

The most cutting-edge, economical, and ecologically responsible two-circuit condensing model available. Few models on the market can match the manufacturer’s 104.6% efficiency and 1.84 cubic meters of gas consumed per hour, even with a heat output of 29.7 kW. The boiler satisfies the highest environmental standards because of its efficient combustion, which lowers nitrogen and carbon monoxide emissions to safe levels (NOx – 22–26 ppm). The standard heating medium has a maximum temperature range of 40-85°C, allowing you to attain 5-40°C in the heated room.

Although the output fan (R.P.M.) has the ability to be precisely adjusted in order to prevent the well-known error 99, it is still advised to take care of the chimney’s insulation and angle of installation.

With such high qualities, the boiler functions flawlessly in practice; major malfunctions are only reported in the event that the operating regulations are broken (e.g., air-logging in the heating system, neglecting annual maintenance).

Official website: where to view all models and operating instructions

The official Rinnai website in Russia can be found at https://www.rinnai-russia.ru.

You can view all of the models that are currently available, along with their technical specifications, by going to the "Gas boilers" section. An original electronic copy of the instruction manual is included with every model. It includes detailed instructions for installation, operation (including how to set the boiler’s flame to the minimum or maximum, temperature, and available modes), and maintenance. It also includes clear schematic images.

Which boiler model is better to choose in the end

The primary factors to consider when choosing a Rinnai are the required minimum power and cost.

In terms of price-performance ratio, the RB-167 RMF, RB-207 RMF (also known as BR-R24), or BR-UE30 models are the best. The first option is preferable for homes up to 150 square meters, and the second is better for homes between 150 and 230 square meters. Depending on heat losses, the third can heat homes as large as 280–300 m³. The models are identical in terms of functionality and usefulness.

If money is tight, you can go with the RB-167 EMF model from the previous generation, which is still useful in the current environment, costs about 10 you rubles less on average, and is not much worse than the new models.

With the RB-277 CMF, the most economical, safest, and eco-friendly model—which also happens to have the least amount of gas consumption—will make the most sense if funds are unrestricted. This will pay off over the boiler’s extended lifespan.

How to figure out how much boiler capacity a private home needs to be heated

The most frequent error codes of gas boilers Rinnai

Malfunctioning ignition. shows an unidentifiable flame that is either nonexistent or extinguishes quickly after being ignited. It is important to check the state of the chimney, the operation of the loads, the gas supply (which may have a closed valve), and the presence of blockages in the heat exchanger.

Unexpectedly putting out a fire. occurs when the burner flame extinguishes itself 20 times or more right after being ignited. can happen at very low gas pressure (the home mains may have this). Verify that the proportional valve fan is in good working order, the flue is installed correctly, and the heat exchanger plate is not clogged.

Temperature fuse malfunction. One disconnected or malfunctioning temperature fuse is the source of the error.

Malfunction of the alert for overheating. letting the boiler know when the heat exchanger’s coolant is low. Verify that there are no leaks in the system, that the thermistor is in good working order, and that the heat exchanger is not experiencing water freezing.

Malfunctioning boiling sensor. occurs when the heating medium’s temperature rises for three seconds above the maximum temperature (more than 95°C). The heating system’s radiators, clogged pipes, or malfunctioning circulation pump could all be to blame for this. Additionally, examine the state of the heating distributor’s opening, the heating thermistor, and the three-way valve.

Thermistor malfunction in the direct water supply temperature. Examine the wiring surrounding the sensor and check the sensor itself for any short circuits.

Low signal from the water level sensor. occurs when there is no water in the reservoir for longer than forty-three seconds. It is necessary to examine the state of the electronic water valve, the water addition switch, and the connections and contacts of the water level electrodes. Verify that there is no blockage in the water separator.

Shut-off of the exhaust. The most common error made when conducting business in Russia during the winter. occurs when combustion products have momentary (less than 90 seconds) exhausting issues. In order to fix the issue, examine the fan and chimney; icing may have built up on the latter.
