7.4 HEATING ECONOMICALLY
The most environmentally-friendly and economic way of heating with wood is to have
your fi re hot but calm. The ash should appear to glow a soft red-orange and should not
glow like a blacksmith’s fi re. Fires like that burn quickly and intensely, leaving little time
for complete combustion.
Your fi re is at its most economical when:
• Using dry and clean wood (as described further in section 9).
• Always ensure even combustion. Stoke with the primary air regulator closed.
To do this, place the combustion air supply slider in the centre position.
• The bed of the fi re should be homogeneous, and the fi re must have easy access to
air. Position the blocks of wood (loosely and evenly) horizontally on the bed of ash,
so that they are separate and several centimetres away from the walls.
7.5 CLEANING THE WINDOW
After several burning hours, a light deposit may form on the inner side of the window.
Once the fi re has cooled down, this deposit can be removed using glass cleaner or
ceramic hob cleaner.
