I have heard that you need to remove the fireplace before using the Eldfast Lining system, surely not?
When quoting we look at which chimney lining system is best, the Eldfast system is used when there is a fireplace fitted on the chimney breast, this is why the Eldfast lining system is used a lot in stately homes where there are listed fireplaces which cannot be removed. We install it in all properties, even when the fireplace is not there, as it is the best lining system available.
Here is a link to an animation we commissioned to show how the system works…

Eldfast lining is particularly good to the help the draw of fireplaces. Chimney stacks can get cold easily, for example an end of terrace or a detached property often has problem drawing and smoke spillage is common. Because the Ceramic material heats up and retains heat, it actually increases the draw of the fire too.
It is an amazing material. It is a ceramic slurry that had a fixing bonding resin, which can withstand a chimney fire, and has been tested to 2000 degrees centigrade and it does not break down, but gets harder.
It has no acidic content, which means that it will not break down over time. Unlike Thermocrete, which is only allowed for gas fireplaces, Eldfast lining is for solid fuel installations as well as gas.
It is expected to last a very long time and is the only cast-in-situ chimney lining system approved by HETAS for use with an open solid fuel fireplace. It can also be used to line a chimney that will be used with wood burning stoves or gas fires.
It does cost slightly more than a flexible liner installation, but sometimes it is the only system that will work. For example a standard 9" x 9" brick flue will often be hard to line with an 8" flexible lining system.
We normally complete a chimney CCTV survey prior to lining a chimney to make sure that we can see which system is more suitable for lining a chimney with an open fire.
When lining chimneys with a stove and a flexible liner (which is best to help the draw of the fire), the chimney does not normally need a chimney CCTV survey, as a 6" flexible liner will almost always go through the smallest 9" x 9" square chimney.
