Balanced flue for wood stoves
A balanced flue can be used with our wood pellet stoves which allows the air to be drawn down a concentric flue design from the exit of the chimney instead of from the room.
Our Island Stoves have been designed as a wood stove that can use a balanced flue (a flue like a gas combi boiler). Our novel stove design allows lower flue termination heights or even horizontal wall exits. Something that is unavailable in the traditional wood stove market.
Although our stoves can be fitted with standard single or twin wall flues we promote the use of a balanced flue for our wood pellet stoves as this design offers many advantages:
- Balanced flue means the building does not need air vents to provide combustion air for the wood stove and thus the house can be designed air tight such as Passive Houses
- Balanced flue increases efficiency (as the air is pre-heated from the flue gases leaving the chimney)
- Conventional flues require a minimum permitted chimney height under Building Regulations is 4.5m from the top of the appliance. By using a balanced flue, the flue can terminate lower than the building
- The problems with down-draughts are also eliminated by the balanced flue design.
Under the right conditions, the balanced flue can also terminate horizontally.
As part of our offering we include a Flue Design Report from calculations using KESA software for balanced flues to BS EN 13384. This can be used to accompany the Building Control application for a shorter flue height.
See the following short video for more details of how the balanced flue works:
The Lundy is offered with a novel connection for use with a Balanced Flue system (such as Poujoulat PGI Pellet 100/150) – as shown in the photo below.
