Features of solid fuel boilers Stropuva
The extended burning time of Stropuva units is their primary distinction. It is accomplished by fusing the product’s design elements with the top layer combustion theory.
Device
A shaft of two steel cylinders, one inside the other, makes up the boiler design. Water, the coolant, is circulating between them.
The air heating zone and the combustion chamber are located inside the smaller cylinder. A telescopic pipe with an air distributor at the end is used to feed a heated air stream into the furnace from above. As the fuel burns out, the air duct settles on top of it and descends with it.
Thermal insulation lines the inside of the casing. The loading chamber and ash pan doors are located on the front panel.
Operating principle
The top-to-bottom burning principle is realized by the apparatus. By allowing the fuel to burn more slowly, it ensures that heat energy is used more effectively. From above, the tab is ignited. The fuel material only burns on its surface. As it burns through, the hearth gradually descends to the lower layers. This guarantees the unit’s consistency and length of operation on a single fuel portion.
This video provides more details about how the Stropuva boiler works.
Advantages
Purchasing such a heating device makes sense because it offers numerous benefits, which we will go over in more detail.
Stropuva boiler advantages:
- Cost-effectiveness. The method of layer-by-layer combustion from the top, unlike the traditional one, does not create "extra heat" that is thrown into the chimney. Heat energy is released evenly and has time to be almost completely transferred to heating the heat carrier, not the street. The boiler does not waste fuel resource in vain.
- Energy independence. The basic version of the heating device does not require connection to the power grid to operate. It is completely self-contained.
- Safety. Absence of electric and gas components reduces the risk of accidents. In case of improper operation, the unit can fail and deform, without causing harm to surrounding objects and people.
- Long burning cycle. The firebox works for up to 30 hours on one load of wood. On coal and pellets – even longer life. The device will have to be serviced less often than once a day. Ideal for those who value their time.
- Low-waste. It is sufficient to clean the ash chamber a couple of times a month. Due to complete combustion there are practically no combustion residues and tars left.
- Efficiency. Efficiency of 85% – much higher compared to traditional water heating devices.
- Design and dimensions. The device has a modern appearance and does not take up much space in the room.
- Wide palette of 7 body colors. Harmonious solution can be chosen for any interior.
Disadvantages
It’s important to consider some of these boilers’ drawbacks as well.
Stropuva device minuses:
- Cyclicality. The boiler goes through stages of firing, combustion and the end of operation regardless of the cycle length. Periodically have to reload a fresh fuel portion, remove ash, and rekindle the furnace.
- Uncomfortable loading window. It is inconvenient to put in and distribute firewood through the small door.
- Cost. To buy a Stropuva boiler, you will have to spend an amount comparable to the cost of a gas boiler.
- High requirements to the quality of fuel. It is allowed to burn material with a moisture content of no more than 20%. Otherwise tar and soot will form on the inner walls.
Types of Stropuva equipment
Depending on the model, Stropuva heating devices can operate on a single or multiple fuel types.
Wood
Hardwood logs, wood briquettes, and peat are the fuel sources for wood boilers.
Pellet
Fuel pellets composed of wood and agricultural residues are burned by the pellet appliance to produce heat energy. The boiler has a specially designed air distributor, grate, and blower.
Universal
In addition to firewood and pellets, models of the universal type also use anthracite and coal. outfitted with specialized components to handle loose raw materials.

What kind of fuel is suitable
There are various fuel types that are appropriate.
Units of Stropuva are excited:
- Hardwood. Logs are stacked evenly over the volume of the furnace. Long ones in the middle, short ones on the edges. The stoking should be completed with large firewood and approximately 0.5 kg of wood chips or shavings for kindling. Wood fuel leaves a lot of ash, which must be removed regularly.
- Wood briquettes. Briquetted material burns longer and more evenly than firewood. It is laid horizontally. Small dry wood chips are used for heating.
- Peat and its briquettes. When burning, the material emits a characteristic sour odor. Working on peat raw material, the boiler emits more harmful substances into the atmosphere than on wood. Do not use this type of fuel in urban conditions.
- Coarse anthracite. It is used only together with wood, otherwise it burns badly. It is recommended to remove unused pieces of ash from the ash and add them to the furnace at the next laying.
- Hard coal. Combine with wood for kindling. The low-quality coal is laid in layers, alternating with logs.
The table shows recommendations for each type of fuel.
Step-by-step instructions for starting the boiler
Pull the rope by the ring on the front panel to raise the distributor before adding fuel, then secure it with a hook. Slide the flap open.
When fully loaded, the fuel resource is utilized as efficiently as possible. Using the upper door, laying is done.
- Wood is placed on the floor of the boiler in layers horizontally as tightly as possible to each other. It is desirable to cover the gaps between the logs with sawdust, chips or shavings.
- A grate is used with coal. Wood is stacked at the bottom so that the grate does not burn through. A thin layer of wood on top – for kindling.
- Peat is stacked in such a sequence: directly on the grate, large briquettes, then smaller ones.
To start a fire, place paper, wood waste, and small firewood on top. Light a fire and allow the hearth to flare. There is a few centimeters of space left when the chamber is covered. Close the door and take the rope off the hook once the temperature reaches 40 to 50°C.
- the lower chamber must not be opened during the boiler operation, otherwise the air coming from below will disturb its operation;
- It is forbidden to top up the fuel until the previous portion burns through, so as not to violate the principle of overhead combustion;
- in order to avoid burns, loading should be done when the temperature drops to 40°C.
The video that follows provides heating instructions.
Recommendations on installation and operation
Select a secluded space with an opening window or supply ventilation before installing the appliance. The boiler room’s ceilings should be at least 2.5 meters high and 4 square meters in size. м. The installation process is completed precisely as instructed.
- The boiler is installed on a concrete foundation 10 cm high from the floor or on a non-combustible base;
- the bottom is covered with concrete mortar, the joint is sealed with heat-resistant sealant;
- keep intervals: in front – at least 1 m of free space, behind – 0.6 m, on the side to the wall – 0.6 m;
- places of connection of the appliance with the chimney and heating system are carefully sealed.
There is more risk because of the heat generator. A sand container for emergency fireplace extinguishment and fire extinguishing tools must be present in the boiler room.
Additional functionalities of the OS:
- fuel and other combustible materials must not be stored near the heater;
- once a month it is necessary to check the condition of the chimney with the help of a mirror, if necessary to clean it from soot accumulation;
- Do not operate in forced circulation systems in case of pump failure or power failure;
- in case of wood heating, the ashes must be cleaned as necessary;
- when using peat or coal, the ash pan must be cleaned every time before a new laying;
- the distributor lifting cable should be oiled to prevent wear and tear;
- it is necessary to inspect the doors for tightness of closing.
Redundancy of work
The possibility of one boiler failing justifies the use of two or more boilers in the heating system. If needed, the plan is also utilized to swiftly expand the capacity.
The heating system’s dependability is increased by the simple assembly of Stropuva units in a cascade.
Benefits of installing a cascade:
- continuity (if one device fails, the other will continue to work);
- Increased capacity (one unit can be used in the off-season, two units in winter);
- Convenience of repair and maintenance;
- space saving in height (for limited spaces – attics, basements).
The drawback of a parallel connection is that you need to connect a separate chimney unit and pipe for every appliance. Study of the circulating pump by Grundfos can be found here.
