Long burning pyrolysis boiler Prometheus Eco
Our review is completed by a story about the Prometheus Eco pyrolysis combustion boiler. The plant produces only one standard size of this model with a capacity of 30 kW. Unlike previous devices that use the traditional method of burning fuel, the Prometheus Eco wood-burning boiler is based on the method of wood pyrolysis.
As is known, in the process of pyrolysis, the combustion of solid fuel occurs in two stages. At the first stage, firewood smolders in the loading chamber with a lack of oxygen, releasing wood gas. By means of a fan, pyrolysis gas is forced into the combustion chamber, where it is burned at a high temperature. Thus, a significantly higher fuel efficiency is achieved than with conventional combustion.
The main requirement for fuel for pyrolysis combustion is its dryness. It is permissible to use firewood with a moisture content of at least 20%. When laying more damp firewood, the boiler will smoke and its efficiency will drop. This is true for all gas generators. For example, a household double-circuit pyrolysis combustion boiler Bourgeois K has the same fuel requirements.
Pyrolysis boilers "Prometheus Eco" are available in two versions Comfort and Optima. "Eco Comfort" is controlled automatically, while "Eco Optima" has manual control.
Let's take a quick look at their advantages:
- The duration of combustion during pyrolysis is significantly higher than during classical combustion. The boiler will have to be loaded less often than usual.
- The almost complete combustion of the fuel, with minimal formation of ash and gaseous wastes, allows them to meet the highest environmental standards.
- Maximum heat removal allows achieving high efficiency values up to 93%.
The main technical characteristics of the Prometheus Eco series:
And finally, the owner's review:
For a long time I chose a pyrolysis machine for giving, in the end I settled on Prometheus Eco. Prices of course bite, but the characteristics impressed me. They installed it quickly with no problems. I have been using it for almost a month now, it burns firewood almost completely. There is almost no ash as such, and there is no smoke from the chimney, but slightly steam. I won’t tell you about the consumption of firewood, next month I’ll try to measure how much it eats.
For more information about installing, piping and connecting the Prometheus boiler, see the following:
The Sibenergoterm plant produces solid fuel boilers for a wide variety of heating systems, which is not difficult to get confused. We hope our review helped you navigate among the variety of Prometheus boilers and you were able to choose the most suitable heater for your home.

Connection and operation
As a coolant, you can choose antifreeze, it will be especially useful if the system freezes. Solid fuel boiler Prometheus is filled to the required pressure in a cold state. Air is bled off at the same time. To melt the cauldron, paper and wood are used.
After the flame is good, load the main fuel. Then regulate the level of the flame with the help of air supply. To clean the grate from ash, it is moved with a lever. The ash pan must be cleaned in a timely manner. It is worth seeking specialized help annually to inspect boiler equipment and check its operation.

Automatic boiler on coal Prometheus Automatic
The line of household coal-fired boilers "Prometheus Avtomat" is represented by one model with a capacity of 40 kW. The manufacturer also produces more powerful devices up to 800 kW, but they are already essentially industrial.
Consider the features of this heater:
- "Prometheus Avtomat" is a long-burning boiler.It is equipped with a bunker for storing coal reserves, and a system for its automatic supply to the combustion chamber. The whole process is controlled by automation and does not require the presence of a person. When the bunker is fully loaded, the solid fuel boiler is able to work autonomously for up to 5 days.
- Automation of the feeding process places special demands on the size of the coal. The main fuel for "Prometheus Avtomat" is brown long-flame coal with fractions from 5 to 60 mm. The use of lower quality coal, although possible, is not desirable.
- The work process is quite simple. Coal is loaded into the bunker and the boiler is melted through a specially designed hole. Further, automation comes into play, which, as necessary, with the help of a stepper motor, supplies new portions of fuel and rotates the grate for uniform combustion. The intensity of combustion is regulated by a smoke exhauster. For the operation of automation and a smoke exhauster, power supply is required.
The official website presents the following characteristics of the 40 kW model:
Let's hear what the owners have to say about them:
Installed "Prometheus Avtomat" in his country cottage. It is very convenient in operation - I threw coal and forgot. True, you need to monitor the size of the coal, large will not work. The only negative is the dependence on the power supply. With constant interruptions in electricity, I think such a boiler is not an option.
For those who prioritize autonomy and duration of burning, this is an ideal option. True, the prices for models bite, and in order to buy a Prometheus Avtomat boiler, you will have to invest a lot.
Product range
Solid fuel boilers for long burning Prometheus are characterized by a different principle of operation, as well as a power difference from 12 to 800 kW. They are intended for heating country houses and facilities for production. The range includes the following models.
TT boilers with different power from 12 to 60 kW, which are designed for 8-12 hours of burning, have a capacious loading chamber. Manufactured from heat-resistant steel 4 mm thick. Productivity ranges from 78 to 84%. For work, coal of different grades is used (an exception is anthracite), sometimes logs. If desired, tubular electric heaters can be installed for additional heating of the liquid. You can see the main technical characteristics in the table.
