Ecostove Top Exit 4″ Flue Kit For Summer House
The Summer House Twin Wall Flue Kit provides all the essential components required to safely install a small wood burning stove in a summer house, garden retreat or outdoor building. Designed as a complete installation package, this kit makes it simple to create a secure, efficient and weather-resistant flue system.
The kit combines single wall flue pipe inside the summer house with insulated 125mm (5″) twin wall flue as the chimney passes through the roof. This helps maintain safe operating temperatures while providing a reliable and durable solution for compact timber structures.
The included 0–30° adjustable roof flashing allows for installation on a range of roof pitches, creating a secure and watertight seal around the flue. A storm collar and rain cap cowl help protect the chimney from the elements, while the wall band provides additional support for the external flue section.
Supplied with both fire cement and heatproof silicone sealant, this kit includes everything needed for a professional installation, making it an ideal choice for adding cosy, efficient heating to your summer house.
