Review of the Prometheus gas boiler
Gas boilers Prometheus 12/16 G are manufactured on the basis of an efficient plate heat exchanger and equipped with modern European SIT automatic equipment with piezoelectric ignition and micro-flare burners.
Prometheus gas fuel boilers are used for heating cottages, residential buildings, apartments, offices, and special premises with a total heating area of 110 to 270 sq. m. meters.
Requirements for installation of gas boilers Prometheus 12/16
The room in which the gas appliance is installed must meet the following requirements:
– Volume of at least 7.5 m³, door or window that opens from the street side. The entrance door should open in the direction of movement from the boiler room. The light switch is installed outside. Ceiling height is at least 2.2m.
– Supply and exhaust ventilation must provide the boiler room with a sufficient amount of air for stable operation of the burner (approximately 15 m³ of air per 1 m³ of burned gas) and 3 times the air exchange of the boiler room in one hour.
– Installation of the Prometheus 12/16 G boiler and chimney is carried out in compliance with fire safety measures. The distance from the boiler unit to combustible parts of the building is at least 250mm, to non-combustible parts is at least 50mm.
The distance from the chimney to combustible parts of the building is at least 400mm, to non-combustible parts is at least 150mm. The boiler is installed on a flat, fireproof base without slopes.
It is advisable to make the chimney from stainless steel with cleaning hatches at each turn of more than 45° and condensate drainage, with cleaning and a pocket for deposits in the lower part. The chimney is insulated from the outside.
When installing a chimney on the outside of the building, measures are taken to protect the insulation from precipitation on the outside and condensation on the inside (that is, the insulation must be ventilated in case it gets wet).
The diameter of the chimney is selected 20-30mm larger than the outlet pipe of the chimney of the Prometheus gas boiler.
The chimney is installed in the receiving plate of the condensate trap in such a way that condensate from the chimney does not enter the inside of the boiler unit and is removed through a special pipe of the trap plate, the drain from which must be drained outside using a flexible hose.
The chimney height is at least 5m. At the same time, ensure that the pipe cut does not fall into the wind pressure zone.
An atmospheric expansion tank is installed at the highest point of the system (preferably indoors) and is reliably insulated. The overflow and supply pipelines of the tank Ø25 and Ø20, respectively, are made of a straight steel pipe along the shortest distance with a slope from the tank and are reliably insulated.
When installing a membrane expansion tank, a pressure reducing valve is installed on the filling line. An air separator is installed at the highest point of the system.
A thermometer and a safety group are installed on the boiler supply pipe.
It is not recommended to install the device in openings, walls and niches.
Prometheus boiler range
Long-burning Prometheus boilers are adapted for coal, the amount of which lasts for a day.
The plant produces a wide range of heating equipment. It is used in various industries and has many modifications.
Floor-standing solid fuel steel boiler on coal
Presented in several models with power from 12 to 60 kW. The devices are made of 4 mm thick steel, which has anti-corrosion properties. The instructions recommend coal as fuel, but firewood can also be used. However, this reduces heating efficiency.
The series is distinguished by a large loading chamber volume, which ensures continuous autonomous operation for 12 hours. The device has a three-pass heat exchanger that increases heating efficiency. The service life of the grate bars has been increased, because They are made of especially durable cast iron. To prevent overheating of the equipment, a mechanism for completely discharging coal into the ash pit has been implemented. The device is equipped with convenient vertical fuel loading and a built-in draft regulator, which provides the necessary heating throughout the entire heating system.
Automatic brown coal boiler Prometheus Automatic
Brown coal burns faster in the firebox because it has a softer structure.
There are two options:
- household power 40 kW;
- industrial – up to 800 kW.
The device is equipped with a reservoir for storing coal reserves. The automatic fuel supply system ensures its loading from the container into the combustion chamber without operator intervention. When the bunker is fully loaded, the Prometheus automatic boiler is capable of operating uninterruptedly for 5 days.
The disadvantage of this equipment may be its demands on fuel quality. For proper autonomous operation, brown coal with fractions from 5 to 60 mm is required. Electricity is required for the operation of the automatic fuel supply system, the rotation of the grate bars and the functioning of the smoke exhauster.
The advantage is ease of use - just load coal into the tank and heat the device through a special hole, then the automation will do everything.
Universal boiler Prometheus Combi
Combination boilers are capable of operating on solid and liquid fuels when changing burners.
They are able to operate equally efficiently on gas, coal, diesel and wood. The ability to use different types of fuel is provided by replaceable burners. The main raw materials for such a device are fuel granules - pellets. They are gaining increasing popularity due to their environmental friendliness. When burned, the granules release smoke into the air, which contains almost no harmful substances. The automation of the device ensures the efficiency of using pellets up to 90%.
The advantage of a pellet boiler is its complete autonomy of operation. The user just needs to open the lid and pour fuel pellets into a special hopper as needed.
The range of models is represented by boilers with a capacity of 32 kW and 45 kW. They are designed to use pellets, but can also run on wood as a backup fuel.
Pyrolysis boiler Prometheus Eco
The pyrolysis operating scheme has a beneficial effect on fuel consumption for the boiler.
Power is 30 kW. Its operation, unlike the traditional method of burning fuel, is based on the method of pyrolysis - heating wood to high temperatures without access to oxygen. With this method, at the first stage, the firewood is very hot in the loading chamber and wood gas is released. Using a built-in fan, pyrolysis gas is drawn into the combustion chamber. Here it is burned at elevated temperatures. This method allows for more efficient use of fuel than traditional combustion.
The plant produces 2 types of pyrolysis boilers:
- Eco Optima with manual control;
- automatic Eco Comfort.
The disadvantage of this type of devices is that the wood for them must first be dried to a moisture content of no more than 20%. If the moisture content is higher, the boiler will produce excessive amounts of smoke and its efficiency will be significantly reduced.
The advantages of Eco boilers include almost complete combustion of fuel and the formation of a minimal amount of waste. These devices are environmentally friendly, the duration of fuel combustion is much longer than in conventional ones. The efficiency value reaches 93%.
Double-circuit gas boilers Prometheus
Floor-standing gas boiler Prometheus single-circuit for a private home
Manufactured on the basis of an efficient plate heat exchanger. Equipped with modern European automation with piezoelectric ignition and micro-torch burners. This equipment is effective for heating residential premises with a total area of 110 sq. m. m. up to 270 sq. m. Double-circuit wall-mounted boilers Prometheus are almost completely autonomous and do not require constant maintenance. They are compact, making them fit perfectly into the interior. The device does not overheat and can be placed near furniture and other devices. At the same time, such boilers are quite effective for heating a private home.
However, there are also disadvantages. This type of equipment is sensitive to the quality of the coolant and requires the installation of additional filters.
The Sibenergotherm plant produces many models of heating equipment for domestic and industrial use. Prometheus boilers are able to satisfy a wide variety of heating system needs. The choice of the most suitable device is up to the user.
Good boiler.
They staged Prometheus 16. The boiler has been running for three seasons now. Burns great, warms up the whole house within 40 minutes.
Before this, all the relatives put it up. Initially I doubted whether it was worth taking it. The price was confusing. After watching the combustion process with relatives, I finally decided to do it.
Three times more economical than the old one. In the morning the coal fell asleep and was forgotten until the evening. The temperature in the house is 26 degrees around the clock.
Subsequently, friends and acquaintances also installed me after me. The only thing that’s a little annoying about the boiler is the cleaning process. And it was annoying at first, until through trial and error I came up with my own device for cleaning a cat.
Now everything is fine. By the way, the boiler needs a constant flow of air, it loves it very much, so I installed a ventilation window for it. And a pipe 150 mm 9 meters.
Prometheus 45 – a large and practical boiler
The house has an area of 230 m2, the husband purchased a Prometheus 45 boiler, installed 2 years ago. The height of the pipe is slightly more than 15 m. The boiler is huge, the ignition valve is terribly inconvenient, it begins to warp all over while moving. But they fixed it, asked the welder to weld small plates and the problem was solved.
The only thing I still can’t figure out is how to properly clean it of resin. Previously, I burned it with a blowtorch and scraped it off while the resin was hot, but nothing really worked out; the cleaning process was difficult.
Operating the boiler is not difficult, I figured it out without difficulty, although the instructions were written in a language that was not entirely understandable. Another integral advantage of the Prometheus 45 boiler is its efficiency; compared to the previous one, the benefit is 2 times. I would recommend it, not a bad option for your home or garden.
Overview inside the module.
Advantages of a coal boiler.
An 80 kW Prometheus automatic coal boiler is installed on the front side.
Fig. 17. (coal boiler)
The loading hopper here is standard, with a volume of about 350 kg. In more expensive models it goes into the ceiling, thus significantly increasing the volume to 3.5 m3.
The operating time of this boiler room from one load is approximately 3-5 days continuously, this is in the off-season or when it is relatively warm outside. Which, in principle, is very convenient, since you don’t have to approach her at all for up to 5 days. Of course, in very frosty weather -35 - -40°C, this volume will be enough for about 1 day of work, that is, the bunker will need to be reloaded every day.
In Russia, the use of coal is one of the most inexpensive types of heating. And with the correct calculation, heating rooms of 800 m2 will cost about 50 thousand. rubles, this is very, very good economical heating.
The only thing is that you just need to reload the bunker and remove the ash as needed. And the heat exchanger itself needs to be cleaned quite rarely. The most common is about 1 time every 3 days. And perhaps once every 2 months, if the temperature regime is observed, as employees at the plant say.
Chimney.
The modular boiler room package includes a special rack made of a tetrahedral pipe. It is screwed on the side, a smoke exhauster is installed on one of its mounts, and the chimney trunk is placed on the other.
Fig. 18. (chimney stand)
Usually the height of the chimney is small in this boiler room, about 3 m, and in other models too, due to the fact that the smoke exhauster forcibly pushes out house gases. Its diameter is approximately 115mm. It is well insulated, with an insulation thickness of about 80mm.
Fig. 19. (chimney insulation)
The top is covered with galvanized steel, since this boiler room is economy class. You can, of course, cover it with stainless steel, but I think that this is not entirely advisable.
Smoke exhauster.
It has a special motor designed for a thermal load of approximately 300°C. It is asynchronous, made in Russia, St. Petersburg.
Electric motor power 0.37 kW. Consumption 370W – very economical consumption. These engines, as I was told at the factory, are very reliable. The company checked many manufacturers and chose the best. You can be sure that your boiler room will operate stably, without failures. The complaint rate is extremely low.
Since these smoke exhausters are made in Russia, they are very inexpensive to replace, about 14-16 thousand. rubles If you wish, you can immediately take a backup one. produces them independently. They are made quite well. Here you can see semi-automatic welding. By the way, welding at the plant is also performed by robots. Not every company can boast of this.

Boiler Prometheus-24 – average
Last October I installed a solid-heated boiler from the manufacturer Prometheus-24, its grates are of a flat type. At first, the heating was not at full capacity, since heating radiators were not installed everywhere in the house. But even in such conditions the heating was good. At first there were problems with the smell in the boiler room, I contacted the service center, where they told me that it was necessary to clean the boiler at least once a week. Now I clean the boiler every weekend and the problem has resolved itself, there is no smell.
As a hassle, I noticed that every time I reheat the boiler starts to boil. Overall, I’m pleased with the quality of the boiler’s work, I recommend it.
Boiler "Prometheus" 12M5 has excellent characteristics, but the design is a little lame
It took us a long time to choose a boiler for our cottage. Since there were problems with the gas connection, a bunker unit (long burning) with solid fuel was needed. Moreover, we are not at home for a long time, so we paid special attention to safety. In terms of price and equipment with automatic safety equipment, the PROMETHEUS 12M5 was the most suitable. It is initially equipped with an explosion valve and a valve for relieving excess pressure in the network, and has a reliable combustion regulator. I also liked the automatic traction control. Based on experience of use, I can say that I was not mistaken in my choice. The boiler is quite economical (especially compared to the simple unit we had before).
One download is enough for more than half a day. The regulators also work great, the temperature in the house remains constant, without sudden changes. I used to think that only electric or gas boilers could do this. True, I didn’t really like the appearance, but this is not important for the boiler.
