Room Sealed Flue Kit (RSF) – Safe and Efficient Flue Systems by Stainlessflue AU
In today’s world, safety and energy efficiency go hand in hand. When it comes to gas heating appliances, one essential component ensuring both is the Room Sealed Flue Kit (RSF). At Stainlessflue AU, we provide advanced RSF systems that guarantee clean combustion, safety, and superior performance for residential and commercial heating systems across Australia.
What Is a Room Sealed Flue Kit (RSF)?
A Room Sealed Flue Kit RSF, commonly known as an RSF, is a closed flue system designed to safely expel combustion gases from heating appliances—like gas boilers or fireplaces—while drawing in fresh air from outside. Unlike open flue systems, an RSF doesn’t rely on room air, making it far safer and more energy-efficient.
How Does an RSF Work?
The RSF uses a twin-pipe or concentric pipe design—one pipe draws fresh air from outside for combustion, while the other expels waste gases. This sealed system ensures the appliance operates independently from indoor air, preventing harmful gases from entering living spaces.
Importance of Room Sealed Flue Kits for Modern Heating Systems
Modern heating units are designed to be compact and airtight. To complement this, RSF systems provide an airtight connection to the outdoors, reducing the risk of carbon monoxide leaks and improving combustion efficiency. For homes and buildings that prioritise energy efficiency and air quality, RSF kits are the gold standard.
Advantages of Using RSF Systems
1. Safety
RSF kits completely separate indoor air from combustion air, preventing dangerous gases like carbon monoxide from entering your home. It’s the safest option for families and workplaces.
2. Efficiency
Because the combustion air is drawn directly from outside, appliances operate more efficiently without drawing heated air from inside the room.
3. Noise Reduction
Modern RSF kits are designed for quiet operation, minimizing noise from air intake and exhaust flow.
4. Energy Savings
An RSF system helps maintain consistent indoor temperatures by preventing air loss—saving on energy bills over time.

RSF Kit Components Explained
Inner and Outer Pipes
The concentric design features two layers—an inner pipe for exhaust gases and an outer pipe for fresh air intake—ensuring full separation between airflows.
Seals and Termination Points
Specially designed seals and terminals prevent gas leaks and maintain airtight integrity, ensuring total system safety.
Condensate Drain
For condensing boilers, an integrated condensate drain prevents moisture buildup, protecting the system from corrosion and blockage.
Applications of Room Sealed Flue Kits
Domestic Heating Systems
Perfect for gas heaters, water heaters, and boilers, RSF systems ensure safe and efficient operation in homes.
Commercial Boilers
For offices, restaurants, and industrial setups, RSF kits by Stainlessflue AU support large-capacity heating systems with stable airflow and high safety compliance.
Gas Fireplaces
Modern sealed gas fireplaces rely on RSF systems for balanced flue performance—keeping your living area warm and safe without air contamination.
RSF vs Traditional Open Flue Systems
Unlike open flue systems, which draw air from the room, RSF systems are sealed and draw air from outside. This eliminates the risk of back-drafting, carbon monoxide leaks, and energy loss—making RSF the superior, modern solution.
Installation of Room Sealed Flue Kits
Installation must always be done by a qualified technician. Stainlessflue AU provides easy-to-install RSF kits compatible with most gas appliances, along with technical support and installation guides to ensure safety and compliance with Australian standards.
Maintenance and Safety Guidelines
- Regularly check for blockages in air intake and exhaust pipes.
- Clean terminal vents to maintain airflow.
- Have your RSF system serviced annually by a professional.
- Ensure all seals and joints remain tight and corrosion-free.
Energy Efficiency Benefits
Because the RSF system isolates indoor air from the combustion process, it significantly reduces heat loss and ensures consistent heating performance. This leads to lower energy consumption and improved indoor air quality.
Environmental Impact of RSF Systems
Room Sealed Flue Kits help reduce greenhouse emissions by optimizing combustion efficiency. They are an environmentally conscious choice for sustainable heating systems in both homes and commercial buildings.
