Yes, you should seal and cap an unused chimney to protect it from damage. Sealing the structure helps prevent moisture damage, which can lead to issues like cracks, spalling, efflorescence, and damaged mortar joints. Capping the chimney is also crucial to prevent blockages, damage from invasive critters, and downdrafts, while still allowing for proper air ventilation to manage moisture. For the best results, consult a chimney professional to select the right type of chimney or flue cap for your home. It's also wise to continue with annual chimney inspections to maintain the structure's integrity.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

While wood stove fans are effective for improving heat distribution, they rely on the stove reaching a certain temperature to operate efficiently. If the stove does not generate enough heat, the fan may not start or may not move air effectively. Additionally, like any fan, wood stove fans cannot cool a stove or reduce its heat output—they only redistribute existing warmth.
