Opening up a fireplace for Inset Woodburner

[Gammy leg]

Hi,

I currently have an working open fireplace which I'm looking to upgrade to accept an Inset woodburning stove ( less mess, more efficient ).
The reason why i'm opting for an inset stove is that I shouldn't need to install a flue liner which would significantly add to the cost of the project.

The fireplace is a standard 600 x 400mm opening with a concrete fireback installed. Because of the tapered profile of the fireback, it will need to be removed to accept the woodburner.

Once the fireback is removed, would I need to line the exposed brickwork before installing the woodburner, or could I leave it as-is?

Thanks

I'm no expert at all, but I'm a little confused as to why you have the idea that a stove being inset would make a difference to the need for a flue liner.

Stephen,

Inset stoves are designed to work with or without a chimney liner. They don't need flue liners if the chimney is in good condition and doesn't leak fumes into the house.

I live and learn, cheers, Stephen

Really ???

I don't think so!

Terry,

After reading the all the spiel online, with an Inset stove there is a choice depending on the condition of the existing chimney and on whether it passes the smoke & draw tests, in which case it is a recommendation rather than mandatory.
Many Inset stoves are designed specifically to fit inside the existing chair brick and which marry up with the throat of the chimney.

Yes - though it's not generally recommended, and is also true with other woodburners (we've recently had one installed with a flue, one without, by the same hetas burnergeezerman)

Liners are not mandatory if the stack is in good condition, if it's in poor condition you have no choice.

A liner can improve the efficiency of the stove by improving the draw of the flue and reducing heat lost to the stack itself especially if the stack is insulated around the liner.
