Description
Kratki NBC 10 3-Sided Wood Fireplace
The Kratki NBC 10 is a modern 3-sided built-in wood-burning fireplace designed to provide an expansive view of the fire from multiple angles.
Its three-sided glass configuration makes the fire a prominent feature within the room, while the large rise-and-fall door provides convenient access to the combustion chamber.
The NBC 10 has a 10kW nominal heat output and a heating output range of 5–13kW. Kratki lists 83% thermal efficiency and an A+ energy class.
3-Sided Built-In Fireplace
The defining feature of the Kratki NBC 10 is its three-sided glass design.
Unlike a conventional front-facing fireplace, the NBC 10 3-sided fireplace has glazing on three sides, providing a much wider view of the flames. This makes it particularly suited to contemporary fireplace designs where the fire is intended to remain visible from different areas of the room.
The three-sided configuration can also work well in open-plan interiors, where the fireplace is positioned as an architectural feature rather than simply against a wall.
10kW Wood-Burning Fireplace
The NBC 10 is designed for seasoned wood and uses a closed-combustion system.
Its 10kW nominal output provides substantial heating capacity, with a heating range of 5–13kW.
The NBC 10 has a heating capacity of approximately 220–300m³. Actual heating performance will depend on factors such as insulation, room volume, glazing, building construction and heat loss.
Rise-and-Fall Glass Door
The Kratki NBC 10 features a rise-and-fall glass door with a smooth lift-up mechanism.
The door can be raised when loading wood into the firebox, while the closed glass provides the large viewing area during normal operation.
Three-Sided View of the Fire
The NBC 10’s three-sided glazing is designed to maximise visibility of the flames.
The heat-resistant decorative glass can withstand temperatures of up to 660°C. An air-curtain system helps reduce soot deposition on the viewing glass during operation.
This combination of three-sided glass and a large firebox gives the NBC 10 a strong visual presence within a contemporary interior.
Heat-Intensifying Ceramic Combustion Chamber
The combustion chamber is lined with Kratki’s heat-intensifying ceramic material.
The NBC 10’s ceramic lining helps increase the temperature within the combustion chamber. The Kratki built-in fireplace also incorporates a ceramic drop-in base designed to provide additional space for burning wood coals.
The ceramic lining is designed to support high-temperature combustion while protecting the steel firebox.
Efficient Closed-Combustion Fireplace
The NBC 10 uses primary, secondary and tertiary combustion according to the current Kratki South Africa specification. The manufacturer documentation lists 83% thermal efficiency for the current NBC 800/400 configuration.
Kratki’s technical data also lists:
- 10kW nominal power
- 5–13kW heating power range
- 83% thermal efficiency
- A+ energy class
- 10kW heat output for space heating
Designed for seasoned deciduous wood with moisture content of 20% or less.
Using properly seasoned firewood supports efficient combustion and helps reduce excessive smoke and deposits within the chimney.
Steel Construction
The NBC 10 is constructed from steel designed to withstand the high temperatures generated during wood burning.
The NBC 800/400 configuration is approximately 87.6cm wide, 147cm high and 62.2cm deep, with a weight of approximately 275kg.
The fireplace uses a 200mm flue outlet and a 125mm air intake.
Consider the substantial size and weight of the NBC10 when designing the fireplace enclosure and supporting structure.
3-Sided Fireplace for Open-Plan Interiors
A 3-sided fireplace can provide a strong architectural focal point while allowing the fire to be viewed from different parts of the room.
The Kratki NBC 10 can be incorporated into a purpose-built fireplace wall or used as a central architectural feature within a larger open-plan space.
Its three-sided glass design makes it particularly relevant for installations where visibility of the flames from multiple viewpoints is important.
The final installation must be designed around the manufacturer’s requirements for clearances, ventilation, combustion air and flue installation.
