Benefits
LOG INDOOR UNIT
The high grade log module with stainless steel hopper is suitable for logs up to 0.5 m in length. Its innovative wood gasification technology lets it operate with high efficiency and extremely low emissions. This results in particularly low heating bills, even with high flow temperatures – and when it gets really cold. Logs are amongst the most favourably priced and crisis-resistant fuels available.
AIR SOURCE OUTDOOR UNIT
The combination with the air source outdoor unit makes heating with logs even more attractive. The automatic selection between economical log operation when temperatures drop and utilising the air source heat pump in milder weather, when lower flow temperatures are required, makes this system particularly efficient. The automatic holiday mode, dual mode fail-safe assurance and the utilisation of power generated on site offer a unique level of log heating convenience previously unseen.
EFFICIENCY AND CLEANLINESS
The unique combustion concept, with lateral rotating combustion chamber, is clearly superior to conventional combustion systems when it comes to efficiency, flexibility and protection of the environment. It enables very long periods of extremely clean combustion.
INCREDIBLE CONVENIENCE
Optional automatic ignition offers the highest level of convenience in log burning mode – not forgetting the highly useful ash separation/ash box, and robust, semi-automatic, cleaning operation. Logs can be ignited subject to time and temperature. The ignition can also be used to provide a useful heat-up function. Naturally, operation can also be continued automatically by means of the air source outdoor unit.
Heating without energy ties
Energy costs, consumption and availability are issues that will continue to increase in importance in the years ahead. This hybrid system already offers persuasive solutions and makes feasible standalone values of up to 90 % and higher, even in older buildings. To achieve this, an energy supply system for a private home requires a photovoltaic system with the ability to utilise generated power on site (EV), a small battery storage unit and the utilisation of residual power by the air source heat pump, combined with a highly efficient pellet heating system for cold and sunless winter days.
HIGH GRADE COMPONENTS
To safeguard unsurpassed reliability, our BMK systems are made exclusively in Austria, from high grade materials. The perfectly made and acid resistant stainless steel hopper, the resilient silicon combustion chamber, the internally air cooled induction fan, the robust lambda probe and the high grade air servomotor achieve previously unattainable longevity and low maintenance costs.
Highest level
of convenience
It's all a matter of technology
Hopper
The stainless steel hopper is resistant to acid and therefore optimally protected against corrosive gases. The additional lining also prevents possible damage from metallic foreign objects. Consequently, BMK means durability.
Lower box (with ash box)
The unique separation of ember bed and combustion chamber, in conjunction with the special air preheating, ensures the highest gasification temperatures. As a result, the BMK also sets new benchmarks when it comes to the combustion of wood with varying qualities, such as hardwood, softwood or wood remnants.
Display
The integral recharge indicator keeps you informed at all times of the current status of the buffer cylinder, so you'll know when to recharge.
A++ heat pump technology
These quiet air source heat pumps operate with inverter technology. As part of the process, the refrigerant is initially evaporated by the environmental energy in the outdoor unit. It is then compressed using highly efficient technologies. The heat is then transferred to the heating system inside the condenser. The high level of efficiency to A++ rating is ensured by the large heat exchanger. Finally, the refrigerant is relaxed again under controlled conditions, and the refrigerant temperature reduced to the required base level.

Wood is a sustainable fuel with excellent combustion values. It grows locally, is available in almost unlimited amounts, and offers short transportation routes.
Air is available anywhere and at any time, in practically limitless amounts. The highly developed and extremely efficient hybrid systems from Guntamatic utilise air as a source of heat only when outside temperatures are warm/mild, that is when its use is at its most advantageous.
