How do you build a chimney for a smoke-free fireplace indoors?

Building a chimney for a smoke-free fireplace indoors in Valheim is essential for maintaining a functional and safe base. Smoke buildup can cause health damage to your character, so proper ventilation is critical. To create an effective chimney, you need to understand the game''s smoke mechanics and how to manipulate building pieces to direct smoke outside.\n\nFirst, smoke in Valheim rises naturally and spreads outward in all directions. If smoke cannot escape, it will fill your indoor space, making it hazardous. To prevent this, you must create a vertical chimney that allows smoke to rise and exit through an opening in your roof. Start by placing a fireplace or hearth in your desired location. Ensure it is not too close to walls or other structures, as this can trap smoke.\n\nNext, build a chimney structure above the fireplace. Use wooden or stone walls to create a vertical shaft. The chimney should be at least two tiles high to ensure smoke has enough space to rise and disperse. For a more efficient design, make the chimney three tiles high, as this provides additional clearance and reduces the risk of smoke spilling back into your home.\n\nAt the top of the chimney, leave an open space or use angled roof pieces to create a vent. Angled roofs, such as the thatch roof or wooden roof pieces, are ideal because they allow smoke to escape while protecting the chimney from rain. If you use a flat roof, ensure there is a gap or hole for smoke to exit. Be cautious not to block the chimney''s opening with other structures, as this will trap smoke.\n\nOne common challenge is smoke leaking into the room if the chimney is not tall enough or if the fireplace is too close to walls. To solve this, ensure the chimney extends above the roofline and that the fireplace is centered within the chimney structure. Additionally, avoid placing furniture or other objects near the chimney''s base, as they can obstruct smoke flow.\n\nFor players in the Black Forest or Mountain biomes, stone walls are a durable option for chimneys, as they resist damage from enemies and harsh weather. In the Meadows biome, wooden walls are sufficient and easier to craft. Regardless of the biome, always reinforce your chimney with support beams or pillars to prevent collapse.\n\nFinally, test your chimney by lighting the fireplace and observing the smoke flow. If smoke escapes cleanly, your design is successful. If not, adjust the height or width of the chimney and ensure there are no obstructions. With these steps, you can enjoy a smoke-free indoor fireplace, making your Valheim base cozy and functional.\n\nPractical tips: Use the hoe to level the ground before building to ensure a stable foundation. Always carry extra materials like wood and stone in case adjustments are needed. For advanced players, consider adding decorative elements like banners or torches to enhance the chimney''s appearance while maintaining functionality.
