Twin Wall Flue Systems

Bonfire are fully HETAS approved specifically for twin wall flue installations by HETAS (This is a separate qualification) and so can sign off the installation on behalf of the building inspector to fully satisfy the law and of course your house insurers.

Our twin wall flue pipe is a metal tube (flue) insulated with an inch of insulation (two layers of stainless steel with insulation between). Stainless and black powder coated systems are fully interchangeable. 

The insulation is necessary to keep the gases hot. Twin Wall flue still gets hot on the outside, lets us use our experience to ensure you and your family stay safe.

Bonfire can supply any colour required whether to match a paint colour or timber cladding so you can be assured of the best performing and best value solution for your application.
