Stoves & cookers

Concept for success: Own patents

Our development engineers in the Haas+Sohn plants in Austria, the Czech Republic and Hungary work on new patents and further development of existing products. Each year around 300,000 euros is invested in the development of new technology.

We also enjoy excellent cooperation with technical universities with the specific aim of developing new standards in combustion technology. As a result, Haas+Sohn can itself become active in implementing its own ideas, testing and taking innovations to the production stage.

Our excellent equipment features are marked on all our stoves and fireplaces.

 

Fully automatic electronic air control

The i-control function controls the stove air inlets with a small electronic motor (only 6 W in operation). The corresponding air inlet is opened or closed depending on the combustion temperature.

Autoair coal

The patented Dual Control Function allows the stove temperature to be set with automatic control in coal operation and ensures a consistent room temperature with constant heat dissipation. Whether wood or coal, the automatic regulation controls the volume of air supplied and thus ensures excellent efficiency. With optimal ease of use, heating cost savings and clean combustion.

Slow coal combustion

Embers from brown coal can provide continuous heat for up to 12 hours. You also enjoy the added benefit of lower fuel consumption and optimal ease of use.

Auto Air

With consistently high efficiency and without a power supply, you make savings in heating costs and time due to cleaner combustion, minimal cleaning required and maximum ease of use.

Easy-Control

All three airflows – primary, secondary and nozzle air – are ergonomically and comfortable controlled with just one lever. You benefit from cleaner combustion that allows you save in heating costs.

Heat Accumulator

Heat storage block – With up to 10 hours of heat radiation, you can enjoy enhanced comfort whilst saving time, money and fuel.

Heat storage block – Made of magnesite stone (density 4) The new Haas+Sohn storage block has the double storage capacity of soapstone!

Heat exchanger

The perfect supplement to central heating utilises part of the heat produced for direct heating. The residual heat is injected into the central heating system. Thus you have an optimal cost and energy-saving heating alternative while the seasons are changing.

External air connection

By predominantly using external air for the combustion, you save heating costs. Enjoy safer and smoother operation, as well as the benefits of cleaner combustion.

Independent from room air

RLU equipment (DIN 18897-certified) is ideal for low energy and passive houses, as well as thermally renovated buildings, as the combustion air is only supplied from outside due to the additional tightness. Thus controlled domestic ventilation without indoor air monitor is possible.

While not heating – lockable supply air connection

The air inlet can be closed while the stove is not in use, which prevents the warm room air from escaping through the fireplace.

Automatic door lock

The door gently closes and locks – elegant and reliable.

Austrian Environment Label UZ 37

Denotes environmentally friendly products with very low emission values (< 20 mg/m³) and renders proof that goods are produced environmentally friendly.
