Justus Usedom 5 W 2.0 Wood Stove 5 kW Steel

Justus Usedom 5 W+ 2.0 Wood-Burning Stove with Integrated Heat Storage

The Justus Usedom 5 W+ 2.0 Wood-Burning Stove combines black steel with cast iron elements and its modern design. With its 5.5 kW nominal output, it can heat up to 88 m³ of room volume and creates a cozy atmosphere. The special feature of this wood-burning stove is the integrated W+ (warmthPLUS) heat storage. With the thermal charging of the storage stones, the stove continues to emit heat energy into the room for many hours after the fire has gone out.

The body is made of high-quality steel, the door and flap are made of solid cast iron, and the combustion chamber is made of vermiculite. The Swedish stove is available in different variants. In addition to the model in purist black steel, you can also get the stove with a soapstone or sandstone cladding. The prism glass gives the fireplace a unique touch.

Features & Benefits

• Heat storage W+ "warmePLUS"
  This special storage material is placed over the combustion chamber into the dome of the stove and, depending on the loading, can continue to release heat into the room for up to 10 hours after the fire has gone out.
• 24-hour continuous operation
  As a special feature for quality and environmental friendliness, the stove was designed to be operated for 24 hours - ideal for continuous heat supply during the heating season.
• Justus Triple Air System
  The special air system always ensures optimally dosed combustion air, making the combustion particularly clean and efficient.
• Integrated Glass Cleaning System
  A specifically guided airflow prevents the condensation and deposition of flue gases on the inner side of the glass - for consistently clear views of the fire.
• Pleasantly Tempered Door Handle
  The air-cooled handle remains pleasantly cool even during operation and allows safe opening of the firebox door.
• Firewood Compartment
  An integrated compartment for neatly storing firewood keeps things organized and always has the wood within reach.
• Multi-point locking
  The multi-point locking prevents the fire door from warping due to high temperatures and ensures stable combustion quality through particularly good tightness.

Application & Area of Use

With a nominal heat output of 5.5 kW, the stove is suitable for rooms up to 88 m³ in volume. The connection is via a 150 mm flue pipe collar, either to the rear or top. The connection height for the rear flue connection is 1080 mm from the bottom edge.

Instead of using the valuable room air, outdoor air can optionally be used for combustion. For this, the stove must be equipped with a connection nozzle for external combustion air can be retrofitted. This is particularly necessary in small or well-sealed rooms, where only a little oxygen is available.

Permitted fuels include wood, wood briquettes, and lignite. The maximum log length is 25 cm. When setting it up, minimum distances to combustible materials must be observed: 200 mm at the back and sides, 800 mm in the front radiation area.

With a weight of 126 kg, the stove requires a stable base and should be installed by two people. Do you still need the appropriate accessories for your Justus fireplace stove, for example, stove pipes for connection to the chimney? No problem, you will of course also find them in our shop.

Approvals & Standards

• Ecodesign Stage 2 - Meets the requirements of Stage 2 of the Federal Immission Control Ordinance for environmentally friendly combustion
• DIN EN 13240 - Tested according to the European standard for room air-dependent appliances for solid fuels
• 15a B-VG for Austria - Approved for the Austrian market according to local building regulations

FAQ: Frequently Asked Questions about the Justus Usedom 5 W+ 2.0 Wood Stove

For what room size is the Justus Usedom 5 W+ 2.0 wood stove suitable?

With a rated heat output of 5.5 kW, the stove heats rooms up to 88 m³ in volume. This corresponds to about 35-40 m² of living space with a standard ceiling height. In well-insulated houses, it can also heat larger areas. The actual heating performance depends on insulation, room height, and desired temperature.

How long does the W+ heat storage continue to release heat after the fire is out?

The integrated W+ heat storage with about 35 kg of storage mass can, depending on the charge, continue to release heat to the room for up to 10 hours after the fire has gone out. The storage stones are heated during the burning process and continuously release the stored energy - providing pleasant residual heat even without an active fire.

Can I install the wood stove myself, or do I need a professional?

The installation is basically possible, but requires expertise and approval by the chimney sweep. With a weight of 126 kg, it should be set up by two people. Important are the minimum distances to combustible materials and a suitable base. The connection to the chimney must be done professionally. More about this in our magazine: Setting up a wood stove yourself: Instructions, Tips & Chimney Sweep Approval

Which firewood is best suited for the Usedom 5 W+ 2.0?

Recommended is oven-dry firewood with a maximum of 20% residual moisture, e.g., beech, oak, or ash. The maximum log length is 25 cm. Wet or treated wood reduces efficiency and increases soot deposition. Alternatively, wood briquettes or lignite briquettes can also be used.

What does the 24-hour continuous operation mean for the Justus Usedom?

The stove is approved for continuous operation over 24 hours - a quality feature for environmental friendliness and safety. Since wood does not hold embers as long as coal, fuel must be added regularly. This allows for a constant heat supply throughout the entire heating period without operating breaks.

Do I need external combustion air for the wood stove?

In modern, airtight houses with controlled ventilation, external combustion air is often necessary to avoid negative pressure. The stove has a standard connection for external air supply with a diameter of 100 mm. The corresponding connection piece must be ordered separately. In older or less airtight buildings, room air is usually sufficient.

Justus - German stove tradition since 1837 Justus is a German wood stove brand with roots dating back to 1837 and today belongs to the Oranier group. The range extends from fireplace stoves to pellet stoves and solid fuel cookers - many models with the optional warmePLUS storage system for up to 13 hours of residual heat. The brand stands for a wide range with optimized combustion technology and a particularly balanced price-performance ratio.
