  • Reduced humidity: By eliminating excess moisture, the fan helps prevent mold and mildew growth.
  • Enhanced fireplace efficiency: The fan promotes proper airflow, allowing your fireplace to burn more efficiently and produce more heat.
  • Cost savings: Installing a DIY chimney exhaust fan is a cost-effective alternative to professional installation.

Materials Needed

  • A small electric fan
  • Cardboard or plywood
  • Aluminum foil tape
  • Screws
  • Wire cutters
  • Electrical tape
  • Marker
  • Drill
  • Ruler

Step 1: Measuring and Cutting

Measure the dimensions of your chimney opening and cut the cardboard or plywood accordingly. Make sure it fits snugly inside.

Step 2: Preparing the Fan

Position the small electric fan on the cardboard or plywood, ensuring that the blades face towards the chimney opening. Use screws to secure the fan in place.

Step 3: Securing the Fan

Use wire cutters to strip the ends of the fan’s power cord. Connect the fan’s wires to a power source using electrical tape. Make sure the connection is secure.

Step 4: Installing the Fan

Place the cardboard or plywood with the attached fan inside the chimney opening. Use screws to secure it firmly in place.

Step 5: Sealing the Edges
