H5 wood boiler
Easy operation
Wood boiler without electronic elements and fan.
Compact boiler size, large hopper
Thanks to the clever design solution, the boiler can be placed even in smaller spaces. The large hopper can hold up to 66 — 83 liters of fuel.
Minimum emissions
5th emission class and minimum harmful emissions.
Saves on heating costs
Up to 30% lower fuel consumption compared to old solid fuel boilers.
H5 is a range of gasification wood boiler. Thanks to its sophisticated design, it burns fuel without electricity and also achieves high combustion quality.
Easy to operate
- The gasification process is achieved without the use of electronically controlled elements and a fan.
- Possibility of operation in gravity systems without the need for a power connection.
- Connection compatibility with U26 boilers.
- The loading door is located at the front of the boiler with a large opening for easy loading.
- Variability of opening the loading and ash door from the right or left.
- Variability of placing the grate lever from the right or left.
- Easily regulate the power using the primary and secondary air dampers.
- Easy maintenance and cleaning of the boiler.
- Undemanding to chimney draft.
Proven design
- The small size of the boiler ensures that it fits into very small spaces without the need for structural modifications.
- The voluminous hopper is from 66 to 83 liters of fuel.
Economical and ecological operation
- Efficiency of almost 90% ensures efficient use of fuel energy.
- Low fuel consumption minimizes operating costs.
- It falls into the 5th emission class and meets the conditions of ecodesign.
- Low wood consumption together with a large hopper reduce the frequency of fuel addition.
- Boilers have up to 30% lower consumption compared to old combustion boilers.
- High-quality combustion results in very low emissions even without the use of a fan or other electrical equipment.
Long service life
- The boiler sheet thickness of 5 mm guarantees a long service life of the boiler.
- Grate made of high-quality cast iron.
- Above-standard 5‑year warranty on the tightness of the weld.
- Long-term proven and customer-tested product reliability.
