„Dual-Fire-Technology“ raises the standard:

ORANIER Dual-Fire-Technoloie Holzvergaserofen Hektos Aqua

A wood stove used with a chimney and it’s natural draft achieves peak efficiency of over 90 percent

Dual Fire from ORANIER is convincing in many ways - pioneering technology

Based on the wood gasification principle, ORANIER has developed the "Dual-Fire technology", with a convincing peak efficiency of over 90 percent, and outstanding values of CO and particulate matter emissions. The boiler stove "Hektos Aqua" which already works with this technology, appears surprisingly compact according to its performance of 10kW.  This year’s new edition is “Aeolus" (6 kW), which uses the same technology. Both devices are now available in with either of the attractive soap- or limestone cladding.

The principle of the "Dual-Fire" has been around for some time already, even though it has not been commonly used in wood stoves. Now ORANIER has seized this technology, and of particular interest is the operation principle: firstly, the fire in the upper chamber of the furnace is lit as usual. After the fire has burned down to glowing embers, more wood has to be put in the combustion chamber. About a minute later the fire is ablaze again, at which point it is time to close the combustion slide bar.

 

Highly efficient: two combustion chambers get the most out of the wood

By the natural draw of the chimney, the wood gases that are released are guided into the lower combustion chamber for efficient combustion and low-emissions.

Subsequently, the exhaust gases are directed to the back of the two combustion chambers along the heat exchanger into the chimney. Compared to traditional stoves, ORANIER achieves an increase in efficiency and comfort, using this new technology. With the maximum capacity of 18 kg of wood, it is possible to achieve a burning time of four hours or more.

 


 

Der Kaminofen mit Speichermasse

A wood stove with heat storage is even more capable. After saving the heat of the combustion the stones emit it slowly into the living room.
After the fire burned down, the heat storage provides continuous heat for several hours.

The wood stove with boiler function

The technology of wood stoves with boiler function allows to spread the heat, produced by the wood stove, around the house.

It is based on an easy concept:

A part of the heat produced by combustion is branched off by the heat exchanger. The heated water is led to radiators around the house. Cooled down, the water returns back to the oven and starts over the cycle.

Profilierte Feuerraumauskleidung   

Profiled burning chamber lining

The furnace lining has profiled vermiculite components with high strength and attractive surface. It looks nice and provides the required turbulence of the gases for clean combustion.

Wärmespeicher „wärmePLUS“  

Heat-storage "Heating Plus"

The integrated special-mixture can save heat and emit it to the room up to 13 hours after the fire extinguished.

Automatikregelung  

Automatic control

A special feature of environmental friendliness. The oven can be operated non-stop.

Use only permitted fuels! Check the manual.

24 h Dauerbetrieb   24 h continuous operation

A special feature of quality and enviromental friendliness. 

The Oven can be used temporary unlimited. Use only permissible fuels. Check the manual!

Raumheizvermögen 88 m³   Room heating capability

The room heating capacity is used to select the proper burning stove performance.

Wirkungsgrad >80%  

Efficiency

The efficiency describes the actual usable part of the fuel energy. The residual energy is required for the function of the chimney.

JUSTUS Safe-Verschlusssystem  

ORANIER safe-locking system

The closed door remains permanently tight. The hydraulic system is almost maintenance free and hardwearing. The door is easy to use and provides an extremely low noise level.
Please notice: Stoves with an approval of the DBIT (German Institute for Building Technology) can be operated independent of ambient air in combination with fresh air, flue pipe and firing room without additional safety equipment.

Mehrfachverriegelung  

Multi point locking system

The multi-point locking prevents warping of the fire door caused by high temperatures. In addition the special sealing prevents from unwanted air supply and and keeps the combustion quality stable in the oven.

Externe Verbrennungsluftzufuhr   External combustion air supply
In modern, more dense buildings with controlled ventilation systems, the combustion air must be supplied from the outside so there can not arise a vacuum in the living room. This requires a separate external air supply.

Please notice: The simultaneous operation of a stove with solid fuels and controlled ventilations systems is only permittet, if the stove has an approval under building law as independent of ambient air stove according to DBIT. The stove has to be equiped with a security device e.g. low pressure warning device that has acces to the ventilation systems and is able to turn them off in case a vacuum arises. 

Please find more information about DIBT in the users manual.

Scheibenspülung  


Airwash system

A deliberately conducted airflow prevents condensation and deposition of flue gases at the inside of the glass. This keeps the window clear.

Dreifach-Luftsystem  

Triple-air-system

The special ORANIER triple-air-system provides for the ideally dosed air supply exactly where its needed for the combustion. The desired result is an especially clean and efficient combustion.

Wasser-Wärmetauscher  

Water-heat-exchanger

Water heat exchanger in stoves offer the option to supply a portion of the thermal power produced into the central heating system. As a result a saving in oil and gas and a reduction of CO2 emissions occures.

Brennkammer Länge der Holzscheite 33 cm  

Combustion chamber: length of logs

ORANIER combustion chambers are dimensioned for log length from 25 to 40 cm.

Luftdurchströmter Griff  

Air-flow handle

By air circulation thru the ergonomically shaped handle the temperature at the surface is largely reduced.
