Need a complete stove & installation kit?
Choose your package - each includes the premium stove and the complete installation kit in the price. For single-storey builds (garden rooms, extensions), pick the Single Storey Kit - no existing chimney needed. In two-storey homes, choose the Internal Two-Storey Kit (flue routes inside and out through the roof) or the External Two-Storey Kit (flue runs up the outside) - neither requires a chimney. If you already have a chimney, the Chimney Pack includes a 10 m liner and everything to connect and safely line it. Need a tweak or a custom layout? Our experts offer a free design service - call 01670 206 999.
