About us

Innovation is our tradition – since 1854.

Since 1854

In 1854, Wilhelm Ernst Haas Senior and his son Wilhelm Ernst Haas Junior took over the iron foundry in the Neuhoffnungshütten in Hesse – the foundation stone for today's company HAAS+SOHN. Even then, they showed foresight and innovative power.

Today, HAAS+SOHN is a full-range provider in the industry and specializes in modern stoves and cookers. The range extends from fireplace kits to wood and pellet stoves and cookers.

Since the beginning, our goal has been to provide our customers with a good time. Our extensive knowledge and know-how has been recognized through numerous awards. This claim forms the basis that makes HAAS+SOHN a unique brand of high quality – characterized by design, innovation and excellence. Our success on the European market confirms this path.

HAAS+SOHN fleet – Europe-wide availability

Today, HAAS+SOHN is one of the most successful suppliers of stoves and cookers. A dense network of distribution partners throughout Europe ensures the rapid availability and high visibility of our products, making HAAS+SOHN one of the leading suppliers in Europe.

Innovation is our tradition

For over 170 years, we have been rethinking heat. We develop and manufacture in Austria – and combine the craftsmanship of the founding years with the technology of tomorrow. Here is an excerpt of what modern HAAS+SOHN stoves can do today:

Top technology

Our HSP 4.0 pellet stoves bundle what is technically possible: fully automatic room temperature control, ember bed level control for constantly efficient combustion, and permanently monitored combustion for maximum safety. Operated via color touch display, weekly program, or app – plus DoubleAir for a second room, Eco mode, and XL tank for up to four days of warmth without refilling.

Control

WLAN Local & Global with App

Control your stove comfortably from the sofa or worldwide on the go. The HAAS+SOHN app regulates temperature and programs, sends push notifications for cleaning and status, and connects up to five stoves for the whole family – secured via SSL encryption.

Operation

Why water-carrying pellet stoves from Haas+Sohn?

The turbos for your central heating! Clever heating: central heating with a pellet stove while protecting the environment. Water-carrying stoves combine the cosy warm ambience and high operating comfort of a pellet stove with the efficiency of a central heating system. They intelligently use all of the energy, optimise the efficiency of a central heating system and prevent radiation losses. So you can comfortably enjoy the warming fire of your pellet stove, heat in an eco-friendly way and save heating costs with a clear conscience!

The perfect addition to your central heating – hot water generation via heat exchanger

Automatic adjustment to different pellet qualities guarantees clean, cost-efficient combustion as well as safe, trouble-free operation. Cleaning effort is also minimised.

Easy, clean heat exchanger cleaning – ensures the longevity of your stove

Easy and clean cleaning of the heat exchanger using a patented cleaning system – for a long service life of your water-carrying pellet stove. Operation without a water connection and buffer tank is not possible. Please have the water connection carried out by qualified professionals.

Hydraulic module

The optional module can be installed in the stove to save space. It consists of: circulation pump, safety valve, venting, return flow boost, and controls the stove's water circuit. Connection optionally to the rear or downwards into the floor.

How it works

Part of the heat is used for direct room heating. The rest is absorbed by a buffer tank, which is also fed by other energy sources such as a solar system or boiler. As required, the heat from the buffer is used to feed the central heating or for domestic hot water heating.

Clever heating – at a glance

  • energy-saving heating
  • direct room heating
  • indirect heating of other rooms
  • the perfect heating alternative in the transitional seasons
  • the optimum in efficiency and operating comfort with WLAN control, conveniently via your smartphone
Why wood stoves from Haas+Sohn?

In every detail, Haas+Sohn stoves stand for reliability, easy operation and modern heating technology. Our appliances are tested under the EN 16510 standard.

01 RLU – the safest choice for modern homes

The appliance draws the air required for combustion entirely from outside. This ensures safe operation in today's highly airtight buildings, where ventilation systems or negative pressure could impair conventional stoves. The appliances are fully airtight, feature a self-closing door and take no air from the room. This represents the highest safety level in modern new builds. Why is an RLU appliance the better choice?

  • Safety in every situation: no backflow of flue gases into the room, no CO risk – even under negative pressure.
  • Worry-free use with ventilation systems: fully compatible with domestic ventilation with heat recovery – no additional components or special permits required.
  • Stable, clean combustion: thanks to the external air supply, combustion remains constant – regardless of the air pressure in the room.
  • Recommended by chimney sweeps: in many new builds, appliances with RLU certification are explicitly required – avoiding later approval problems.
  • Future-proof technology: with ever stricter energy requirements, this design is increasingly becoming the standard.

02 Automatic primary air control

The integrated sensor reacts to the temperature in the combustion chamber and regulates the primary air supply automatically. More air is provided during lighting; as the combustion-chamber temperature rises, the air volume is reduced automatically. Result: more even combustion, less soot, longer burn time and lower wood consumption – entirely without electricity and maintenance-free.

03 Easy Control air regulation

The intuitive one-hand operation ensures an optimum air supply at all times. The stove works more efficiently, delivers more warmth from less wood and remains simple and comfortable to operate.

04 Snap lock door latch

The precise, self-closing door mechanism ensures a perfect seal of the combustion chamber. This leads to stable combustion, greater safety and clean operation – with every heating cycle.

05 External air supply (external air connection)

The stove draws its combustion air from outside, so the room air remains untouched. Particularly advantageous in modern, well-insulated houses where a controlled fresh-air supply is essential.

06 Heat storage block

The special storage elements release the heat evenly over a long period. The room stays pleasantly warm even after the flame has gone out – for a natural, lasting feeling of comfort.

07 Continuous-burning function

The stove can be operated over longer periods with stable heat output. Ideal for anyone who wants constant, reliable warmth with minimal refuelling.

08 Combustion chamber materials – durability and efficiency

  • Fire concrete – the premium class: the light, homogeneous fire concrete meets the highest demands on temperature resistance and durability. Its solid structure ensures dimensional stability and excellent heat emission for many years – and gives the combustion chamber an elegant, high-quality appearance. The ideal solution for intensively used, heavily demanded fireplaces.
  • Chamotte – the robust heat-storage classic: proven for decades, chamotte convinces with high heat-storage capacity: slow cooling, long-lasting heat emission, high mechanical strength, excellent resistance to thermal stress. Chamotte ensures stable, reliable operation.
  • Vermiculite – light, fast-reacting combustion chamber lining: a modern, lightweight material with outstanding heat-insulating properties: fast heat-up, quickly reached optimum combustion temperature, low weight that reduces the overall mass of the appliance.

Haas+Sohn Energiespar-Zugregler
The original from Haas+Sohn – patented innovative

The draft regulator in motion

Explainer animation: how the pendulum flap automatically balances the chimney draft — just press play.

How the energy-saving draft regulator works

Funktionsprinzip
  1. Draft increasesIf the draft in the chimney becomes too high due to weather conditions (e.g. in wind), the pendulum flap opens.
  2. Air flows inAir from the boiler room flows into the chimney and balances the negative pressure.
  3. Optimal combustionThe chimney draft at the boiler remains constant – fully automatically and precisely, entirely without electricity.

Even when idle, the pendulum flap opens, ventilating the chimney and keeping the heat in the boiler. Permanent chimney ventilation also prevents soot formation in the chimney.

The explosion flap (ZugEx design) In addition to draft regulation, the explosion flap opens in the event of deflagrations that can occasionally occur in the boiler. The short-term overpressure is relieved immediately – damage to the heating system is effectively prevented. Mandatory for wood gasifier, pellet, and oil boilers (pressure atomizers).

Your advantages at a glance

Save energy immediately and permanently

  • Increase efficiency
  • Reduce boiler idle losses

Longer service life of the heating system

  • Prevention of chimney soot
  • Immediate pressure relief for deflagrations (explosion flap version)

Quick and easy to implement

  • Easy and space-saving installation
  • Absolutely maintenance-free system

Savings year after year

Incredibly fast amortization: With oil heating, the energy-saving draft regulator saves several hundred euros per year depending on consumption – the acquisition is usually amortized within a year.

      Frequently Asked Questions

      Answers to all aspects of planning, installation, operation and service of your fireplace. Technical terms are explained in our glossary.

      Planning & Purchase

      What heating output (kW) do I need for my room?
      This depends mainly on the living area, room height, and the building's insulation standard. As a rough guide for average insulation, you need about 1 kW per 10 to 15 m² of living space – well-insulated new builds require significantly less. Our output calculator on the website calculates a more precise recommendation for your situation. Please clarify the dimensioning bindingly with your specialist dealer or chimney sweep, as an oversized stove runs continuously in unfavorable low-load operation.
      Wood stove or pellet stove – which suits me better?
      A wood-burning stove for log wood offers the classic fire experience, is loaded by hand, and functions without electricity – ideal if you value the ritual of heating or want an electricity-independent heat source. A pellet stove ignites and regulates automatically, maintains the desired temperature via thermostat or app (e.g., our SmartLine), and is suitable for anyone who prefers convenience and constant heat; it only requires a power connection.
      Can my stove heat automatically according to a schedule?
      Yes – our HSP series pellet stoves have a weekly program: up to three heating times can be programmed for each day of the week, so that the living room is already warm in the morning when you get up or in the evening after work. Many models – such as the HSP 8 Lucca II or the Pelletto IV Grande – are additionally equipped with a WLAN module and can be controlled via the HAAS+SOHN app at any time, even on the go.
      Which stove heats even during a power outage?
      All our wood stoves and cookers for log wood function completely without electricity and reliably keep your home warm even during a power outage. The HS 40 cooker makes you particularly independent: it not only heats, but also offers a full cooking area with its hotplate – cooking and heating work even during a longer power outage. Pellet stoves, on the other hand, require an electricity connection for ignition and pellet feeding.
      What does "water-carrying" mean and when is it worth it?
      A water-carrying stove has an integrated water exchanger (water pocket) that transfers part of the heat to the central heating system or buffer tank of the house. Thus, the stove not only heats the installation room, but also supports the central heating and lowers its consumption. This is particularly worthwhile in combination with a heat pump or solar thermal system. The integration into the heating system is planned and installed by a heating technician.
      Can a stove support my central heating?
      Yes – with a water-carrying device: The HSP 6 WT pellet stove delivers up to 10 kW, of which up to 6.8 kW flows into your heating circuit or buffer storage via the integrated water pocket – automatically controlled and room-air independent. If you heat with log wood, you can achieve the same with the AQUA water-carrying fireplace insert (17 kW, of which 11 kW is water output). The integration into the heating system is planned and installed by a heating technician.
      Which stove is suitable for a new build with a ventilation system?
      In airtight buildings with controlled domestic ventilation, you need a room-air independent (RLU) stove that draws its combustion air directly from outside. For wood stoves, the Waleria HSC RLU is suitable, for example; for pellet stoves, the HSP 4.0 series, the Pelletto IV RLU, and the HSP 8 Lucca II RLU, among others, are suitable. Whether your building requires an RLU device should be clarified with your chimney sweep.
      Which stove stores heat even when the fire is out?
      Models with natural stone cladding – such as the UPPSALA IV HSC with Serpentino, the MONTEGROTTO, or the HSP 2.STONE with soapstone – absorb the heat of the fire and release it gently into the room for hours. Wood stoves with the suffix HSC like the INZELL easy or the SALZBURG.l easy can additionally be equipped with an optional heat storage block, which increases the storage effect. This keeps it comfortably warm long after the fire has burned out.
      Can I also cook and bake with the stove?
      Yes – our wood cookers combine heating and cooking: the compact HS 40 add-on cooker offers a steel hotplate with different temperature zones, and the HSH 81 wood cooker additionally features an oven compartment for bread, roasts, and casseroles. And the ELLMAU COOK easy wood stove comes with an adjustable glass-ceramic hob, which – like all our log wood appliances – functions completely independently of the power grid.
      Which stove fits in small or well-insulated rooms?
      For small or well-insulated rooms, a pellet stove is often the best choice: the HSP series models automatically modulate their output down to 2.4 kW and thus avoid overheating. For wood stoves, compact models starting at 5.5 kW like the LUMO S or the VARO S are suitable. What output your room actually needs can be determined by our output calculator on the website.
      Can I control my stove via app?
      Yes – many of our pellet stoves are equipped with a WLAN module and can be controlled via the HAAS+SOHN app: adjust temperature, program heating times, and check the operating status – at home in the WLAN or on the go. These include the HSP 2 models CUBE and STONE, the HSP 7 Diana, the HSP 8 Lucca II and Volterra II, as well as the Pelletto IV Grande. This means the apartment is already warm before you walk through the door.

      Installation & Safety

      What safety distances do I need to keep?
      The binding safety distances are model-dependent and are stated in the operating manual and on the type plate of your device – in particular the distances to combustible materials such as furniture, wooden walls, or curtains. On our product pages, you can find a 3D view of the distances according to EN 16510 for many models. Compliance is checked by the chimney sweep during final inspection.
      Do I need a permit for my stove?
      The connection of a fireplace is subject to notification and acceptance: before first startup, the responsible chimney sweep must inspect and approve the system. It is best to involve them in the planning phase – they will also assess whether your chimney is suitable for the desired device. The exact requirements differ depending on the country and region.
      What does "room-air independent" (RLU) mean and when do I need it?
      A room-air independent device draws its combustion air directly from outside via its own duct instead of from the living room. This is important in modern, airtight buildings – especially with controlled domestic ventilation – because otherwise negative pressure can develop, drawing flue gases into the room. Many of our models therefore carry the suffix RLU. Whether your building requires a room-sealed device should be clarified with your chimney sweep.

      Operation & Fuel

      Which wood can I burn?
      Only natural, dry log wood with a residual moisture below 20% – wood achieves this after about two years of dry, airy storage. Painted, coated, or impregnated wood, chipboards, and waste must not be burned: they damage the appliance, chimney, and environment and are prohibited by law. The maximum log length of your model can be found in the technical data on the product page.
      Which pellets should I use?
      Use certified quality pellets according to ENplus A1 (Ø 6 mm). Inferior pellets cause more ash and slag, contaminate the burner pot, and can lead to malfunctions – damage caused by unsuitable fuel is also excluded from the warranty. Always store pellets dry, as damp pellets swell up and become unusable.
      Why does the viewing window get covered in soot and what helps against it?
      The most common causes are too damp wood, too little combustion air (air regulator closed too early), or continuous operation with too small a flame. Many of our devices have an airwash system that sweeps the pane with preheated air and significantly reduces soot deposits. Pay attention to dry wood, the recommended reload quantity, and operation according to the manual – then the view of the fire remains largely clear.

      Service & Maintenance

      Where can I get spare parts and service for my device?
      Our service partners in your region will help with maintenance, repair, and spare parts – you can find them via the service partner map in the service area. You can also easily order spare parts in our online shop. Alternatively, you can reach us directly via the service form. Please have the article number of your device ready; it is printed on the type plate and in the documents.
      How often must my stove be serviced and cleaned?
      Empty the ash drawer regularly and clean the combustion chamber or burner pot according to the operating manual – for pellet stoves, this is particularly important for trouble-free operation. A thorough maintenance is recommended once a year, ideally before the heating season. Chimney sweeping is regulated by law; the intervals are determined by the responsible chimney sweep.
