When you choose a package, you get the premium MediumTinderbox on Log Box, 5kW, ECODesign with single storey extension kit shown on this page plus a complete installation kit, so everything is ready for your installer in one delivery.

For single-storey spaces such as garden rooms, bungalows or extensions, pick the One Storey Kit – it is designed to work without an existing chimney. In two-storey homes, choose the Inside Two-Storey Kit if you want the flue to rise internally and exit through the roof, or the Up & Out Two-Storey Kit if you prefer the flue to run up inside and then outside the wall – both options avoid the need for a chimney.

If you already have a chimney, the Chimney Pack partners MediumTinderbox on Log Box, 5kW, ECODesign with single storey extension kit with a 10m flexible liner and all the adaptors and fixings needed to connect and safely line the chimney. It's our most popular option and usually offers the best overall value when bought with this stove.
