CAN YOU USE A FLUE FITTED FOR A GAS FIRE FOR A WOODBURNER? Accounts and book-keeping for builders plus mortgage and remortgage information

[Rita Kirk]

I have a gas fire and a metal flue that was professionally fitted into the chimney in my house some 3 years ago. I am now thinking of replacing the gas fire with a woodburner. It is possible to re-use the existing flue; or will I have to arrange for a new one to be fitted (ie specific for a woodburner)?

Rita Kirk,
Depends on the diameter of the flue liner which was installed, the minimum for wood burners is 125mm.

Hi
It does not depend on the diameter, it does depend on the class of liner. Class one is for solid fuel and class 2 is for class 2 gas (1 has a natural draw the other does not). The older open gas grates used a class one 180mm or 200mm id liner and the class 2 liners were/are mainly 125 or 100mm (occasionally 150mm). Class one is 316 grade and double skinned with w 10 year warranty (you could also use 904 grade with a woodburner which has a 20 year gaurantee). Gas class 2 is single skinned and will burn out straight away if used on solid fuel.
A hetas registered person should install or you could get a builder to do this and have the work signed off by buildiung regs however the liner should be data plated and the stove certificated. You will also need a CO alarm to room.
