NORRA PF stove fireplace

Think a fireplace only heats when a fire is burning? Discover NORRA – a grateless fireplace insert with dedicated modular heat-storing caps and heat-storing brackets. Designed for maximum efficiency.

Storage power without compromise

The NORRA insert is, above all, advanced thermal engineering. This model is truly distinguished by its proprietary modular heat-storing system. Special heat-storing brackets are mounted on the sides and rear of the unit, ensuring even heat distribution. But that's just the beginning. The NORRA insert's additional power lies in its superstructure. On a special stabilizing base (purchased separately) around the flue and outlet pipe, you can arrange up to 5 layers of modular heat-storing caps (ready-made sets of 1, 3, or 5 layers of heat-storing caps are also available). The modularity of the entire structure means that by setting the appropriate number of layers of storage caps, you can adjust the height of the entire structure to the building conditions.

Modular storage caps are arranged in layers without the need for separators. This solution guarantees a monolithic structure and maximum heat storage density. The storage modules in NORRA inserts are characterized by a high density of approximately 2.7 t/m³. The storage modules increase the device's operating efficiency by storing thermal energy generated during the combustion process – during use, they absorb thermal energy from the device body and the flue pipe. After combustion, the stored energy is gradually released.

The effect? The fireplace radiates pleasant warmth into the room for up to 4 hours after the fire has been extinguished. The gradual release of stored heat improves the comfort of everyday use, stabilizes the room temperature, and minimizes energy loss. This solution also translates into more economical and efficient use of the energy generated by the device.

Intuitive operation and personalization

The NORRA fireplace was designed with the user who values comfort in mind. The interior of the insert, lined with TERMOTEC material (with a choice of light or dark combustion chamber lining), not only looks elegant but also ensures greater heating efficiency and longer temperature retention inside the fireplace. Furthermore, thanks to the use of a vermiculite deflector, the fireplace reaches its optimal operating temperature faster.

Operation is extremely simple – you control the entire air supply with a single, smooth regulator. The NORRA is a grateless insert – the wood burns on the ash, minimizing waste and maximizing energy utilization. In practice, this means that the fuel burns to fine ash, leaving only a small amount in the fireplace. The resulting thermal energy from the wood is utilized to its full potential. The fireplace boasts a high efficiency of 86%.

Particularly noteworthy is its universal design, which aligns with the latest interior design trends. The base with 5-step height adjustment is an integral part of the stove. Furthermore, the NORRA insert is available in several configurations: models with a straight front or corner models. All models are available in traditional and stove-mounted versions, facilitating the design of a custom tiled installation while maintaining high heating parameters.

Ecology and the highest quality of the PRO series

The NORRA insert is a responsible choice. The device meets strict Ecodesign standards and the German BImSchV 2 standard, as well as Flamme Verte, Wallonair (BE), 4 Stelle Certificato ambiental (IT), DIN+, and 15a B-VG. It has also been tested to the new, more stringent EN 16510 standard. This guarantees clean combustion, low emissions, and the highest energy efficiency. Thanks to its sealed combustion chamber and external air intake, the stove works perfectly with heat recovery systems, making it the perfect heart of modern, energy-efficient homes.

As part of the prestigious Kratka PRO line, NORRA guarantees craftsmanship from the finest materials, confirmed by a 10-year warranty.

Why choose a NORRA insert:

■ Maximum storage power: A modular set of caps and storage hangers on the sides, back, and top of the insert, dedicated to the NORRA model, stores heat from the device's body.
■ Modular cap set: The height of the storage layers can be adjusted to suit the building's requirements. A choice of 3 or 5 layers of storage modules placed on the top of the insert around the flue to extend heat release time.
■ Insert body: made of 4 mm thick boiler sheet metal.
■ Maximum energy utilization: storage slings recover energy from the body. Depending on the version, there is the option of adding 7 (straight insert) or 5 (corner insert) storage slings. Temperature from the body is recovered by the storage mass, which releases energy for up to 4 hours.
■ High efficiency: a deflector system that lowers exhaust gas temperature while maintaining low wood consumption. The NORRA insert is characterized by a high efficiency of 86%.
■ Available versions: Choose a model with a straight front or the attractive BS corner version.
■ Grateless combustion: The wood burns on the ash - less fuel loss, minimizes fuel waste, and maximizes energy utilization.
■ TERMOTEC lining: Available in light or dark versions, it has accumulative properties - it releases energy into the environment. Soot particles are burned after reaching an operating temperature of 350 °C. This ensures that even light TERMOTEC remains clean when it reaches its operating temperature.
■ Three deflector system: effectively extends the exhaust gas path. The solution increases combustion efficiency and allows for better use of thermal energy.
■ Full control over the combustion process: Control is via a single, intuitive regulator, guaranteeing precise control of the device's operation. The use of a rotary damper with a Teflon washer mounted on a bronze sleeve ensures exceptionally smooth, light, and silent operation of the mechanism.
■ Perforated handle: An ergonomic handle with a modern texture ensures comfortable opening and slower heating.
■ Heat-resistant glass: with temperature resistance up to 660°C.
■ Clean glass system: An air curtain that reduces soot buildup.
■ Triple air supply system: Primary air, secondary air, and an air curtain to optimize the combustion process.
■ Stability and flexible installation: adjustable legs and a 360° movable exhaust outlet adapt the device to any interior. The standard integrated base with 5-step height adjustment up to 110 mm ensures high insert stability.
■ Ideal for heat recovery: a sealed combustion chamber designed for modern, energy-efficient construction.
■ meets the standards: Ecodesign, BImSchV 2, Flamme Verte, Wallonair (BE), 4 Stelle Certificato ambiental (IT), DIN+ and 15a B-VG.
■ 10-year warranty: the highest quality confirmed by belonging to the Kratki PRO line.
■ energy safety: the fireplace is a heating solution independent of other heat sources - it means safety and reliability in every situation and an alternative source of heating in the event of a power or gas outage.
