Twin Wall Flue Systems
Twin wall flue systems allow you to install a stove safely and efficiently in homes without an existing chimney. Designed with double insulation, these flues ensure that exhaust gases are expelled correctly while keeping the outer pipe cooler, making them ideal for stoves installed outside a traditional chimney.
Why Do You Need a Twin Wall Flue?
- Safe operation – expels fumes safely while maintaining appropriate surface temperatures
- Compliance – meets UK building regulations for wood, multi-fuel, or gas stoves
- Non-chimney installation – allows a stove to be installed in homes without an existing flue
- Flexible setup – can be used for single or multi-storey installations with straight or angled runs
Styles and Components
Our twin wall flue range includes:
- Double insulated pipes – available in multiple diameters for different stove types
- Adapters, bends, and T-pieces – to configure the flue according to your installation
- Top caps and rain cowls – protect the flue from the elements while ensuring proper draft
Before You Choose
Not all stoves require a twin wall flue. These systems are primarily for homes without an existing chimney or for installations outside a standard flue. Check your property layout and stove type carefully to determine if a twin wall system is necessary. Professional installation by a HETAS-qualified engineer is strongly recommended.
