Justus Usedom 5 - Cladding wood stove 5.5 kW

Justus Usedom 5 Wood-Burning Stove with Sandstone Cladding and 5.5 kW

The Justus Usedom 5 wood-burning stove combines robust steel technology with the natural heat storage of sandstone - for anyone who values long-lasting warmth and natural appearance. With a nominal output of 5.5 kW, it can heat rooms up to 88 m³ (about 35-40 m² of living space with standard ceiling height) and is, as one of the few stoves in its class, approved for 24-hour continuous operation.

The wood-burning stove is made of high-quality steel, and the combustion chamber is made of vermiculite. The massive cast iron door is very robust and guarantees high tightness and durability. You have the option to customize the stove - in our shop, you can choose between the variants of cast gray steel and black steel with different natural stone claddings. The prism glass gives the Swedish stove an individual touch. The integrated glass cleaning system, a compartment for tidy storage of firewood, and a pleasantly tempered door handle leave nothing to be desired.

Features & Advantages

• Justus Triple-Air System
  This special system always ensures optimally dosed combustion air and improves the efficiency to 80%.
• Continuous operation over 24 hours
  As a special feature for quality and environmental friendliness, Justus designed the beautiful Justus Usedom 5 so that the fireplace can be operated for over 24 hours. Since wood does not maintain embers as long as coal, fuel must be added more regularly.
• Sandstone Cladding
  The natural stone cladding stores heat and continues to release it long after the fire has gone out - for an even room temperature without reheating.
• Prism Glass Viewing Pane
  The special prism glass offers an unobstructed view of the flames and gives the stove an individual appearance.
• Integrated Glass Cleaning System
  Keeps the viewing pane clean and ensures a clear view of the fire - less cleaning effort in daily use.
• Pleasantly Tempered Door Handle
  The air-ventilated handle remains pleasantly cool even during extended use and allows for safe opening of the door.
• Firewood Compartment
  Integrated compartment for neat storage of firewood directly at the stove - practical and visually appealing.

Application & Area of Use

The Justus Usedom 5 wood stove is ideal for living spaces up to 88 m³ and can be operated with wood, wood briquettes, or lignite. The maximum log length is 25 cm. With its weight of 103 kg, it stands firmly but should be installed by two people - a permanent location should be planned in advance.

The flue connection with a diameter of 150 mm can be installed either to the rear or upwards, allowing flexible installation options. Instead of using the valuable room air, air from outside can optionally be used for combustion. For this purpose, the wood stove must be retrofitted with a connection nozzle for external combustion air. This is particularly necessary in small or well-sealed rooms where only little oxygen is available.

The stove is designed as Type 1 for multiple occupancy and requires a draft of 12 Pa at nominal heat output. The minimum distances to combustible materials are 80 cm in front, and 20 cm on the sides and back.

Approvals & Standards

• DIN EN 13240 - European standard for room-air-dependent fireplaces for solid fuels
• Ecodesign emission limits Stage II - Meets the requirements of Stage 2 of the Federal Immission Control Ordinance
• 15a B-VG for Austria - Austrian approval for operation
• VKF for Switzerland - Swiss approval of the Association of Cantonal Fire Insurances

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

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

The stove heats rooms up to 88 m³ with a nominal heat output of 5.5 kW. In well-insulated houses, it can also warm larger open living areas. The sandstone cladding additionally stores heat and releases it evenly.

Can the Justus Usedom 5 really be operated continuously for 24 hours?

Yes, it is approved for continuous operation over 24 hours. Since wood does not maintain embers as long as coal, you need to regularly add fuel. For true continuous burn, the Justus Usedom 5D is recommended, which is specifically designed for longer ember retention.

Which wood is suitable for the Justus Usedom 5 wood stove?

Use 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 and lignite are permitted. More on this in our magazine: Storing firewood correctly: Tips for optimal drying and storage

How do I properly start the Justus Usedom 5?

Start with dry kindling and fire starters, then gradually add larger logs. The triple air system automatically regulates the combustion air optimally. Open the air supply fully at the beginning and reduce it after ignition. The glass cleaning system keeps the view clear. More on this in our magazine:How to Properly Start a Wood Stove - Step by Step

Do I need a professional company to install the Usedom 5?

The installation can be done by yourself, but the initial commissioning and connection to the chimney must be inspected by a chimney sweep. With a weight of 103 kg, you should set up the stove with two people. Plan a fixed installation location with the required minimum distances.

What does external combustion air mean for the Justus Usedom 5?

The stove can draw combustion air directly from the outside via an optional connection nozzle, instead of using the warm room air. This is particularly useful in tight, energy-efficient houses or small rooms where there is little oxygen available. The connection is made to the rear with a 100 mm diameter.
