Goat Stove Connection: Chimney-free Summer House - Selecting Pipes, Wall Pass-through & Isolation

The safest and most sensible solution is to use a proper prefabricated chimney system with an inner flue liner and keep it away from all combustible parts; do not run exhaust through wood/chipboard or solve the penetration with a larger hole and silicone [#13934157] [#13953151] [#14018674] A brick or hollow-block shaft is only a load-bearing outer structure, so the flue gases must go through a ceramic or steel insert inside it, not through the blocks themselves [#14018674] [#14017967] If the wall is brick, the brick itself does not need extra insulation, but anywhere the chimney passes near wood or other combustible materials you must maintain safe distances and use non-combustible insulation; long uninsulated sections make draft worse and increase soot/tar buildup [#13955716] [#13934157] Avoid tees and sharp bends if you can, because they make cleaning harder and raise the soot-fire risk; if you must offset the pipe, a gentler 45°/segmented bend is better and the chimney should remain cleanable from above [#14023126] [#14028431] If part of the chimney will be outside, insulate it rather than leaving a long cold section, because cold pipes soot up quickly and weaken draft [#13934157] [#13955716] [#14028431]
