Fireplace and Chimney
Do you have an existing fireplace or chimney?
An easy question if you are using your fireplace currently. However in older properties, the fireplace may have been bricked up and therefore will require opening up again to accommodate your new stove. Normally a stove needs a gap of at least 150mm either side, 75mm behind and 300mm above.
If you have an existing fireplace, it is highly likely that you will have a working chimney. However to make sure your stove burns efficiently and correctly, the chimney is lined with a stainless steel flexible liner.
What’s the difference between a chimney and a flue: if the chimney is a polo mint then the flue is the hole.
Don’t have a fireplace or chimney?
Not to worry – you have a couple of options.
Firstly you can build a new chimney, which is fine if you are at the planning stage of a new build or extension.
However most new stoves will go into existing properties and that’s where the second option is used – a twin wall flue system. This is 2 metal metal tubes protected with about an inch of insulation.
A flue system ideally needs to finish above the highest point of your ridge on the roof. It also need to get thereby taking the simplest vertical route with no bends greater than 45 degrees.
