A fireplace insert can transform your existing fireplace into a more efficient and stylish heat source. These enclosed units—typically made from steel or cast iron—trap heat, reduce smoke, and make maintenance easier. Whether you’re upgrading for warmth, aesthetics, or energy savings, this guide by fireplace distributor will help you choose the right fireplace insert.
What Is a Fireplace Insert?
A fireplace insert is a self-contained unit that fits inside your existing fireplace. Inserts come in electric, gas, and wood-burning options, with various styles to complement your home. Whether you prefer sleek steel for a modern look or classic cast iron for a traditional feel, there’s an insert for every aesthetic.
Benefits of a Fireplace Insert
🔥 Improved Heating Efficiency – Retains and radiates more heat into the room.
🌿 Eco-Friendly – Produces less smoke and improves indoor air quality.
🛠️ Easier Maintenance – Reduces soot, ash, and wear on your firebox.
💰 Lower Energy Costs – Helps cut down on heating bills by preventing heat loss.
How to Measure for a Fireplace Insert
To ensure a proper fit, take these measurements of your fireplace opening:
📌 Width: Measure across both the front and back.
📌 Height: Measure from the firebox floor to the top, both front and back.
📌 Depth: Measure from the fireplace opening to the back wall.
🔹 Pro Tip: Use a laser measuring tool for precise results.
Choosing the Right Heat Output
Fireplace inserts should match both your fireplace size and your room’s heating needs. The heat output is measured in BTUs (British Thermal Units)—the larger the room, the more BTUs you need.
💡 BTU Guide by Room Size:
- Under 150 sq. ft. ➝ ~5,000 BTUs
- 150-450 sq. ft. ➝ 6,000-10,000 BTUs
- 550-1,200 sq. ft. ➝ 12,000-23,000 BTUs
📝 How to Calculate Square Footage:
- Rectangle/Square: Multiply length × width.
- Triangle: Multiply length × width ÷ 2.
- Circle: Square the radius, multiply by 3.1416, then multiply by 20 to get your BTU estimate.
