Balanced Flue Gas Fires – Advice

A balanced flue gas fire is a room-sealed gas appliance with a glass front. This design of fireplace uses a sophisticated flue pipe system that uses natural convection to draw the fresh air from outside the building for combustion and expels it back to the outside through a separate compartment of the flue. It is the same system that is used on modern combi boilers. When buying a balanced flue gas fire from us we can supply the flue pipes with the fire to ensure you have everything on site to install the fireplace quickly with minimal cost.

The outer pipe draws in fresh air from outside, the inner pipe is the exhaust from the fireplace to take away the emissions.

All balanced flue gas fires are room sealed as they have a glass front. This means that no additional room ventilation is required as the fire draws fresh air in via the flue pipe. Models are available in various sizes and heat outputs. These appliances are classed as high efficiency gas fires and selecting the correct model for the size of room you have is critical. Please check the heat input and efficiency rating of the appliance. If a large appliance is selected with a high heat input the heat from the fire may be too much for the room and become overpowering meaning you will end up not using the fire. The bigger, or wider, the fire the heat input will be higher. We make models from 400mm wide up to 1300mm as that is the most practical range for installation in the UK. There are larger models on the market however please consider the comments above before buying these large appliances.

The balance flue gas fire pipe routing chart shows the type of flue system possible 100/150 or 130/200 and the maximum vertical and horizontal runs per chosen appliance. So you have a great deal of flexibility when deciding where to locate your fire. We can supply both sizes of pipes with our fires and the appliances are compatible with both sizes.
