... a multi-fuel spaceheater, evolved from the Little Devil design.
again,
the advantages of re-shaping the traditional box are numerous: tilting the square shape at 45 degrees allows for much fuller
loading, while the angled front makes for easier and safer access. The fuel charge is always collapsing to the centre of the
stove.
The biggest innovation with the Wedge is the 'split baffle'.
This works the flame path harder for a more complete burn, and by 'splitting' or opening the baffle to the room we
gain another 20% of surface area to the room. It also means the plates won't burn out, as they would if enclosed
completely in the firebox. We also take the opportunity of perforating the bottom of the baffle, to introduce extra air for
re-combustion (i.e. secondary burn).
WEDGE BOILER
....this sturdy fellow designed and built for Alan Dawson's beautifully engineered 'Adaptahaus'; featured
on Cannel 4's 'Grand Designs' in October 2010

... the boiler version of the WEDGE.
The fire chamber is basically a tilted box, double-skinned as a water jacket; the open baffle is replaced with a connecting
baffle boiler. The stove performs a similar function to the SUMO boiler, but is slightly more compact. It provides
an exceptionally high proportion of heat to water (approximately 80%)
We offer this boiler in various sizes: 20, 25, 40 and even
80kws.
the 80kw version is powerful enough to heat a swimming pool!

the base of the stove
echoes the firebox, which makes the ash drawer more accessible, as well as making a sculptural feature of the stove.
The flue can be taken of either horizontally, or vertically

....an early attempt with two split baffles, to send the flame in an S shape round them both;
but perhaps more complications than are really economical ... just the single baffle does most of the work, and no extra
flaps are required. As usual, the simple solution wins out!
