Converting A Fireplace To A Wood Stove: Is It Necessary?

A contemporary wood stove is hard to match for rapid, intense heat, outstanding appearance, and energy savings.

When it comes to buying a wood stove, one of the most common worries is how to vent it. Wood stoves, like all other wood-burning home heating systems, require a good ventilation system. Smoke and gas must be able to depart the house through a secure path. Typically, a stove pipe is used to do this.

Some wood stove purchasers question if they can vent a new wood stove through the chimney linked to their existing fireplace. So let’s take a closer look at this concept.

What Are The Advantages Of Using A Wood Burner Instead Of An Open Fireplace?

If you presently use an open fire, converting to a wood burning stove will provide you with several advantages. Burning wood in a fireplace generates more smoke and is less efficient than using an SIA Ecodesign stove (more on this below). Take a look at some of these numbers to understand what I mean.

  • An open fire is only around 30% efficient, but a stove is 70-80% efficient.
  • SIA Ecodesign is a company that specializes in environmental design. Ready stoves emit 90 percent fewer pollutants than an open fire.
  • To provide the same amount of heat as an SIA Ecodesign Ready stove, a fireplace would require 16 logs.
  • In the UK, open fires are used to burn 40% of the wood. The amount of pollution eliminated if this was replaced with wood burners would be enormous!
  • Wood burning stoves use renewable fuel.

What Do I Need To Pay Attention When Making Wood Stove Out of My Open Fireplace?

You may have already determined that changing your fireplace to a wood burner is the best option for you. Fortunately, you will be relieved to learn that the procedure should be pretty simple! A basic idea of how to open a fireplace for a wood burner is as follows:

  • You’ll need to take measurements of your fireplace recess to figure out what size stove would suit the best. It’s also crucial to have a suitable kW heat output; if it’s too tiny, the room won’t heat up adequately, and if it’s too huge, you’ll be too hot! For a simple method to figure out what size is ideal for your space, use our stove kilowatt calculator.
  • Make sure your chimney is in good working order and that it is swept. Determine the type of chimney you have if you don’t already know. For further information, see our guide to stove chimneys.
  • It’s better to have your stove installed by a HETAS-certified technician. This guarantees that it is both safe and compliant with any applicable building codes. Then, when you’re done, you’ll receive a certificate to show that it’s safe.
  • If you don’t hire a HETAS professional to install your stove, it will need to be assessed by building inspectors to verify it is safe. This will be an additional charge.
  • Check to see if your stove is placed on a suitable hearth. If you previously had an open fire, a stove will most likely be absolutely safe. To be sure, make sure it’s at least 12mm thick, composed of non-combustible material, and that it won’t become hotter than 100°C on your stove.

How To Convert A Fireplace To A Wood Stove

Step 1: Remove the damper from the chimney. By simply unhooking the pin that holds the damper in place, you may remove it. Remove the damper.

Step 2: Using the tape measure, measure the inner measurements of your chimney 2 inches above the aperture from the inside.

Step 3: Using the tin snips, cut a piece of sheet metal to these measurements, adding 1 inch to each side. Next, cut a 1-inch deep slit in each corner of the sheet metal with the tin snips so you can fold over the sides to construct a pan.

Step 4: Create a flange on both sides of the metal piece by bending the sides up. Cut a hole the diameter of the stovepipe aperture in the center of the sheet metal using tin snips. Begin by drilling a hole in the metal pan’s center with a screwdriver, then cutting it out using tin snips.

Step 5: Insert the sheet metal pan into the chimney hole, enclosing the stovepipe entirely. Drive masonry nails into the pan’s flanges and the sidewalls of the chimney with the hammer.

Step 6: To prevent leaks, apply silicone caulk to the pan’s edges where it meets the brickwork and the stovepipe.

Step 7: With the assistance of a buddy, install the fireplace insert in the fireplace. Connect the stove piping and caulk the pipe joints with silicone caulk.

How Much Does It Cost To Convert An Open Fire To A Wood Stove?

The stove itself will usually cost between £700 and £1,500, and the costs of preparing the chimney/flue and fitting the stove will be around the same.

Of course, how much this eventually costs depends on the individual circumstances, so I always recommend that you have a chat with professionals first and visit the property to be able to provide you with an accurate/realistic price.
