Description
Glass on three sides turns the Kratki NBU 11 into the focal point of any room it goes into. This is a large built-in fireplace with a rise-and-fall door, so the glass lifts up for loading and then drops back down to give an uninterrupted view of the flames from the front and both ends.
Kratki NBU 11 Built-in Fireplace Features
A 3-sided fireplace for open spaces
Three panes of glass mean the fire is visible from most of the room. It suits peninsula walls, wide chimney breasts and open-plan living areas where you want the fire to feel like part of the space.
Lift-up glass door
The rise-and-fall door slides up vertically. There is no door swinging into the room, and loading is easy even when furniture sits close by.
Ceramic lining and a deep coal bed
The combustion chamber is lined with Kratki’s heat-intensifying ceramics, which hold heat and radiate it back out. The ceramic internals include a drop-in base that leaves extra space for a bed of glowing coals, so the fire keeps going longer between loads.
Air wash and a heavy steel body
An air wash system cuts down soot on the glass. The steel body weighs 299 kg and measures 52 x 105 x 147.1 cm, with a 200 mm top flue.
Is the NBU 11 right for your home?
Kratki rates the NBU 11 at 14kW for spaces of about 220 to 325 cubic metres. That is a large lounge, an open-plan ground floor or a room with a high ceiling. If your space is smaller, look at our other built-in fireplaces or our Kratki buyer’s guide for lighter models.
Installation in Cape Town
A unit this heavy and this open needs careful design. Our team plans the support, the surround, ventilation and the 200 mm flue with a cowl and flashing that stand up to Cape wind and rain. Learn more about our built-in fireplace design and cladding work, or see the wider Kratki fireplace range.
Kratki NBU 11 FAQs
Does a 3-sided fireplace lose heat to the room faster?
More glass means more radiant heat reaches the room quickly, which most owners enjoy. The ceramic lining stores heat too, so warmth carries on after the fire burns down.
Is there a warranty on the Kratki NBU 11?
Kratki wood-burning fireplaces carry a 5-year warranty. A correct, compliant installation by our team helps keep that cover in place.
