What these specs mean

External air

External air allows the stove to take combustion air from outside the room via a flexible tube, rather than just taking air from the room. This can be useful in newer, more airtight homes. Suitability depends on the installation and property.

12mm hearth

A 12mm hearth suitable stove can usually sit on a thinner decorative hearth, rather than needing a constructional hearth, subject to the manufacturer’s instructions.

ClearSkies rating

ClearSkies is an independent emissions and efficiency scheme for modern stoves. A higher rating indicates cleaner burning performance compared with older stove designs.

DEFRA approved

All of the stoves we sell are DEFRA approved. DEFRA approval means the stove can be used to burn wood legally in UK smoke control areas, provided it is installed and used correctly with suitable fuel.

Distance to combustibles

This is the minimum safe gap between the stove and combustible materials such as timber, plasterboard, furniture, shelves, beams or a wooden fireplace surround.

Efficiency

Efficiency shows how much of the fuel’s energy is turned into useful heat for the room. Higher efficiency usually means less heat wasted up the chimney.
