Which Flue Liner Works Best for Gas or Oil Heating Systems?

Flue liners are essential for venting smoke and gases safely away from your home, but when it comes to gas or oil heating systems, the type of liner you choose is crucial for both safety and efficiency.

Aluminium vs. Stainless Steel

For gas and oil heating systems, stainless steel flue liners are generally the best choice. They are durable, resistant to corrosion, and suitable for high temperatures, making them ideal for venting gases safely. Aluminium liners, while cheaper, are not recommended for oil or gas as they’re more prone to degradation over time, especially in acidic conditions.

Flexibility and Durability

Stainless steel liners come in flexible and rigid versions. A rigid stainless steel liner offers superior strength and longevity, while a flexible one is easier to install, especially if your chimney has bends. If your home uses a multi-fuel stove or you anticipate needing repairs, a flexible liner is a great choice.

Installation Considerations

When installing a flue liner, it’s essential to hire a qualified technician to ensure it’s done to building code specifications. Poor installation can lead to dangerous gas leaks or improper venting. Proper sizing is also critical. Too small a liner can result in poor ventilation, while a liner that’s too large may reduce the efficiency of your heating system.

Conclusion

For gas and oil heating, stainless steel is the safest and most reliable option. Always consult a professional to ensure you’re choosing the right liner for your system and installation conditions.
