How it works:

In ordinary stoves the air enters below the fuel, so that smoke is carried upwards.

The Yorkshire Stove uses the Downburning system where air comes in at the top, the smoke is pulled downwards, so that the smoke [which is tiny particles of unburned fuel] is forced through the very hottest part of the fire and so burns away
as air is introduced through the afterburn
air inlets at the rear of the fire - giving
more heat for less fuel therefore much cleaner combustion.

When burning wood The Yorkshire is clean enough for even the strictest smokeless zone - it's even cleaner than 'smokeless' fuels.

Technical Specification:

Construction: The 'Yorkshire' develops
very much higher temperatures than ordinary fires so the very highest quality
of materials have been used throughout.

 The body of the Yorkshire is made from tough steel plate and cast iron. The
firebars are not of ordinary iron but of chromium alloy for durability. The window
is not glass, but transparent ceramic first developed for the space shuttle. The firebrick lining is manufactured from high temperature heat reflecting material, pressure cast to meet the special design and requirements of the 'Yorkshire'.

Control: Output can be adjusted from
12kW (at approximately 3-hourly
refuelling) down to 2kW (at approximately 10-hourly refuelling). Hard fuels, such anthracite, are recommended for extended burning.
