Featuring Burley's 'Fireball' technology, the Hollywell 9105-C offers astonishing efficiency of up to 90.4% thanks to the stoves three part combustion process.
Primary combustion
Primary combustion is the initial burning of the wood at relatively low temperatures. During primary burn, water is evaporated and large amounts of creosote gas are produced. this creosote holds 60% of the potential energy of the wood, but is often just deposited on the inside of the stove and the lining of the flue,which causes chimney fires.
Secondary combustion
If, however, the combustion chamber is designed correctly by having sufficient insulation to raise the core temperature to 400ºC, and the correct amount of air is introduced, this creosote spontaneously combusts. This creates a chain reaction which increases the temperature inside the stove from 400ºC to 600ºC with no extra use of fuel. This is the secondary burn.
Introducing the air
The Burley Hollywell 9105-C has a unique and patented system of introducing air for combustion, this is called the Fireball. A tubular framework channels air from the intake at the rear, around the fuel bed where it is preheated. The framework extends up each corner of the combustion chamber where the hot air is injected horizontally along the inside of the stove. This creates a vortex which spins anticlockwise and ensures every area of the firebox receives exactly the correct amount of oxygen.
Tertiary combustion
Tertiary combustion occurs by fully burning the carbon, charcoal and ash which is left behind. These contain a huge amount of energy and provide a long rate of heat. Anyone who has barbecued will be aware of how much heat is present in semi-combusted wood. Blacksmith smelt steel on it. The vortex created by the Fireball technology also envelops the entire fuel bed, burning it so completely that there is no need for an ash pan.100kg of wood can be reduced to 1 pint of ash (a ratio of 350:1) which is simply scooped out. No more carrying bucket loads of ash through the house every time you want a fire!
Quaternary combustion
To create even more heat for your room and less soot for your chimney, Burley’s stoves have a unique quaternary (fourth) combustion process. As the hot gases exit the combustion chamber they pass through a mesh filter. The mesh is heated to such a high temperature that when any particles of soot or creosote which have escaped the secondary combustion touch it, they are ignited on contact.
Results
Making a stove which will burn wood is very simple and cheap. Producing and designing a top quality stove which will burn wood efficiently and cleanly is very difficult and is expensive. During product approval, when the European test house was measuring the emissions from the Burley stove, the combustion was so clean they assumed that their gas analyser had broken and sent it away for recalibration!
The catalytic converter included in this model also aids complete combustion, turning carbon monoxide into carbon dioxide, releasing more energy in the process, therefore the stove with catalytic converter will generally have lower CO and higher efficiency than the stove without.
Burley’s research and design has ensured the catalytic converters are working in the perfect temperature band, therefore with normal use they are rated for over 10,000 hours use. Unlike many other catalytic stoves, with average use Burley’s cat’s will never need replacing.
The timeless design of the Hollywell 9105-C is finished in matt black with stylish wooden door handle and easy to use air control lever located at the base of the appliance. With a nominal heat output of 5kW, the Burley Hollywell is a perfect choice to heat standard sized rooms.
The modern, portrait scale of the Hollywell 9105-C can be increased further with the addition of an optional Logstore Plinth which sits at the base of the appliance lifting the height by an extra 183mm (7¼"). This highly advanced stove is made in Burley's headquarters in Oakham, East Midlands using locally sourced materials whilst being as environmentally responsibly as they can.
Simple and modern in design, the Hollywell 9105-C is constructed from steel. The plate steel sections are 5mm and 8mm thick and are welded by robots with the welds applied in exactly the right place and in exactly the right thickness resulting in the steel sections being melted and fused together to make a virtually indestructible construction. Weighing in at 95kg, you can be assured that this cutting-edge stove is built to last giving years of dependable service.
Not only is the Hollywell 9105-C a DEFRA exempt stove and approved for burning wood in smokeless areas, it has passed the tests for the upcoming EcoDesign directive. Ecodesign Compliant stoves have been third party independently verified as meeting the maximum emission limits for particulate matter (PM), organic gaseous compounds (OGC), carbon monoxide (CO), nitrogen oxides (NOx), as well as the minimum limits for seasonal efficiency.
For homes built before 2010, an Air Vent is not normally required when fitting the Hollywell. For homes built after 2010, an optional Outside Air Kit can also be purchased as a Standard Room Seal Kit or Angled Room Seal Kit. The Standard Kit connects directly from the rear of the fire to the back wall. The Angled Kit exits at 900 from the rear of the fire. This can then be connected to standard ducts (available from builders’ merchants), to create a path to an outside wall. A maximum of five 900 angles may be used.
Included free with the Hollywell 9105-C is Burley's 'Thank You' pack which typically contains:
- Spanner to attach and adjust the tension of the air control lever
- Coaster to protect the top of your stove
- Moisture Meter to ensure your wood is dry
- Stove Paint in case you prefer black handles or ever need to touch up any paint work
- Heat Resistant Glove
- Scoop for removing ash
- Allen Key should you wish to adjust the door handle
- A Mug to enjoy a cup of tea whilst admiring the fantastic flame picture
The contents of the kits vary from model to model, so not all the items listed or shown above may be included with your stove.
