Product detailed description

- 8.9-29.8 kW ecological, fully automatic boiler for pellets only

- is designed for perfect pellet combustion so that a pellet burner is built into the left or right side of the boiler, depending on the customer's needs, which fully automatically draws pellets from the storage tank using a screw conveyor. The fuel storage tank is usually located next to the boiler or in an adjacent room and can be of any size (standard 250, 500 or 1000L). Often a part of the boiler room is also used as a fuel storage tank, which is then sufficient for the whole heating season.

The operation of the pellet burner itself is completely automatic. If the burner receives a start command or if there is a need for heating, the conveyor feeds pellets into the burner nozzle and ignites them itself with a heating element (spiral). After the pellets are sufficiently ignited, the burner runs up to the set output, which it maintains until the system (house) is heated. Then the burner switches off and the pellets in the burner chamber burn out completely. The burner is then ready for a new start. The whole cycle repeats whenever there is further demand.

The boiler output and other burner functions are controlled by an electronic control system, which allows the boiler operation to be adapted to the specific conditions of the whole system. Refilling pellets, cleaning the burner combustion chamber and removing ash is done once every 1 – 30 days, depending on the quality of the pellets and the size of the storage tank.
If needed, the boilers can be equipped with an automatic ash removal system for comfortable heating with minimal maintenance.

Required accessories for the boiler:
burner A45	screw conveyor DRA50 - various lengths	pellet storage tank - various

Frequently Asked Questions

• How to choose the correct output for a solid fuel boiler? Base your choice on the calculated heat loss of the heated building, but for wood/coal boilers also consider that the boiler burns for several hours at essentially constant output during one filling - therefore it is common practice to complement the boiler with a buffer tank, which stores excess heat for later use instead of the boiler having to be inefficiently throttled down.
• What else do I need to install this boiler? In addition to the boiler itself, the system usually requires: a buffer (equalizing) tank of appropriate volume, a circulation pump (often already with a built-in Laddomat or thermoregulatory valve against low-temperature corrosion of the boiler), a safety valve, an expansion vessel, and a flue/chimney with sufficient draft corresponding to the boiler output - exact draft values can be found in the technical parameters above.
• What fuel is suitable and what is not? Use exclusively the fuel recommended by the manufacturer for the given model (usually split wood of defined length and moisture, or brown coal briquettes or coal depending on the boiler type) - unsuitable or too moist fuel reduces efficiency, increases the formation of tar and deposits and can damage the boiler.
• What about chimney inspection and legislation? Before putting the boiler into operation, as well as regularly during its use (usually once a year for solid fuels), a chimney inspection/cleaning by an authorized chimney sweep is required by law - without the relevant inspection document, an insurance claim in the event of a fire may also be disputed.
• How much maintenance does the boiler require? This usually includes regular removal of ash and cleaning of heating surfaces/flue gas passages from soot (interval depending on intensity of use, usually in the order of weeks), and once a year a thorough inspection including seals and the chimney.
• Can I install the boiler myself? The actual placement and connection of the boiler to the heating system, chimney and safety elements should be carried out or at least professionally checked by a heating technician - this is a device with open flame, high temperatures and pressure elements, where a connection error can be a safety risk.
