Description
Big rooms need a heater that can keep pace, and the Sentinel Ottawa Square 12 is built for exactly that. It pairs a strong 12kW output with a neat, square-bodied look that feels more modern than a classic round-shouldered stove. Cast iron and steel construction gives it weight and staying power, and the multi-fuel design gives you choice in what you burn.
Sentinel Ottawa Square 12 Features
Heat for larger spaces
With 12kW on tap and a 75% efficiency rating, the Ottawa Square 12 turns most of its fuel into usable warmth. It is a practical 12kW fireplace for homes where a small stove would run flat out all night and still leave cold corners.
Multi-fuel flexibility
Wood is the usual choice, but a multi-fuel grate means you are not stuck when good firewood runs short. Your installer will advise on which fuels suit your flue and how to keep the glass clean.
Top or rear flue
The 150 mm flue can leave from the top or the back of the unit. A rear exit is handy when you want to run the flue through a wall into an existing chimney, while a top exit suits a straight run up through the ceiling.
Solid build, compact footprint
At 42 x 57 x 61 cm and about 118 kg, it takes up little floor space for the heat it gives. The square shape also lines up neatly against a wall or in an alcove.
Is the Ottawa fireplace right for your home?
Sentinel rates it for a heating area of up to 172 m2, so it is a strong fit for a large lounge, a double volume room or an open-plan living area. For a smaller room, ask us about the Ottawa Square 9. You can compare it with other freestanding fireplaces in our range.
