Boilex™ Ultraclean Multi Fuel Stove
Revolutionary stoves that can help improve global health for millions.
An overview of the Ultraclean Multifuel stove
Clean, smoke free, safe cooking is a global challenge:
In the general population, over 3 billion people (c500 million households) cook with smoky fuels on a daily basis, resulting in respiratory diseases such as Pneumonia and Lung Cancer leading to over 4 million deaths per annum; this equates to one death every time you blink or to the population of Ireland, more that HIV/AIDS and Malaria combined. Smoke is also responsible for Cataracts, the largest cause of blindness in the developing world, mainly to women and children as they spend most time in a cooking environment.
In the case of Militaries, they continue to use Hexamine for individual soldiers, which is highly toxic and hazardous to transport. Traditional field kitchens for larger groups of soldiers are predominantly gas powered, which is a potential explosive risk and difficult to resupply.
To meet the challenges of clean cooking in a humanitarian or military situation, Boilex™ have introduced the new Ultraclean Stove for individual and larger group cooking. The Ultraclean stoves will boil 5 litres of water in c11-14 minutes compared with over 30 minutes from comparable stoves and use up to 80% less fuel. This unique stove has a multi-fuel capability, meaning the user can switch between the most readily available fuel from biomass, to liquid, to high energy density fuels from one stove. Made of Stainless Steel, it is robust and guaranteed for up to 5 years (assuming careful daily use).
The Boilex™ Ultraclean stove is ideal for all terrain and all environments and can be modified and tailored to suit specific needs. The Boilex™ Ultraclean stove, accessories and Zip™ Cooking Fuels can be supplied in various formats, from bulk packs to individual stoves, to provide bespoke cooking and water heating solutions.

The core Boilex™ Ultraclean 1 and 2 stoves are designed to work with biomass (wood, wood pellets, wood chips, dung, twigs and crop waste) that can be sourced locally. The fuel is top loaded into the stove using a chute and ideally has a constant 1-2 inches of fuel in the crucible to operate.
The core stoves can be simply modified with the use of specific metal inserts to enable them to operate with alternative fuels such as High Density Fuels or liquids such as Kerosene. The design of the inserts allows the air to circulate in the stove to maximise the performance of the fuel in use.
High Density Fuels
Locally sourced fuels are not always available and that is why Zip™ have developed their cooking fuel blocks. This fuel is based on a naturally derived, sustainable biofuel that is non toxic and burns cleanly with a high calorific value. It is also air transportable so can be parachute dropped into remote locations when required. The smaller Boilex™ Ultraclean 3 stove is designed to operate only using the high energy density Zip™ Cooking Fuel blocks and is significantly lighter than the other Ultraclean stoves. At c1kg, it is designed specifically for military / expeditionary use.
In some situations liquids, such as Kerosene or alcohols, are the preferred or only fuel options readily available. These fuels are highly flammable and less safe to use when cooking. The core Boilex™ Ultraclean 1 and 2 stoves can easily be converted to burn such liquids, again with the use of a robust metal insert and a wicked canister containing the fuel. The design of the insert allows the air to be sucked away from the centre of the stove to produce a flame that is significantly wider and more efficient when transferring heat to a cooking pot or pan. The enclosed nature of the wicked container also ensures the risk of spillage is significantly reduced.
Not only does the Boilex™ Ultraclean range of stoves have profound health benefits, it is also a potential source of income for local communities. The stoves can provide local commerce opportunities for sales, distribution and production of the stoves and wood pellet fuel. The additional service of charging mobile telephones has also proved to be popular. Traditionally in Africa, such micro commerce is adopted by women, who are empowered to create local employment, improve living standards and are able to further support their families with opportunities such as education or commerce.
The advantages of Ultraclean
Clean burn performance.
A Boilex™ Ultraclean stove is categorised as a ‘Forced Air’ or ‘Gasifier’ type of stove. It works by a use of a battery operated ‘fan’ in its base, which is recharged using a solar panel, mains or vehicle battery. The fan blows air up though the sides of the stove cylinder prior to being released into the combustion chamber where it ensures a more complete burn of the fuel. On full power, the stove quickly generates temperatures up to 1000ºc. It is possible to vary the power via a control gauge, which moderates the amount and speed of air flowing into the stove. Being able to control the heat is similar to other cooking methods, such as gas, and is inherently easy to use and more readily culturally accepted. The greater the amount of air, the more powerful the combustion process and the cleaner the fuel burns. The Boilex ™ Ultraclean stoves utilise the latest patented designs to produce a clean burn even at low levels.
This ultra efficient way of burning the fuel results in up to 80% less fuel being needed to cook with (compared to open fires) and up to 40% less fuel than other forced air stoves. This not only saves cost for the user but may also result in significantly less time spent collecting fuel, allowing the user to spend time on more added value tasks.
Unique to Boilex™ is the capability of using many types of fuel, including biomass (wood chips, wood, twigs, dung and pellets), liquids (Kerosene, Methyl Esters and alcohol) and high energy fuels (such as Zip™ Cooking Fuel, alcohol gels and Hexamine), all from one stove. This gives improved convenience to the user and the ability to switch from less efficient or more expensive traditional cooking stove/fuel combinations, many of which are also unsafe, as the table below shows.

How long does the Boilex™ Ultraclean stove take to charge?
About one hour from a standard mains charge and 10 hours from the solar panel. A full charge should be sufficient for a week’s use.
Can I use the stoves indoors?
Ideally no, due to the production of exhaust gases. The stove and fuel should only be used outdoors. The stove can be used for indoor cooking, provided there is adequate ventilation, which means with a ventilation system that carries all fumes and exhaust gases outdoors.
Can I use the stoves inside my tent?
No, the stoves should not be used in an enclosed space. There must be adequate ventilation to carry away the fumes and exhaust gases outdoors.
How long do they take to assemble?
The Boilex™ Ultraclean stove comes fully assembled, though there are different set up options associated with the switch between the chosen fuels. Switching can take up to 1 minute, so not complicated or time consuming.
Can you put the stoves on any surfaces?
Yes, the stoves have rubber corner pieces that ensure they can be placed on any surface without scratching. There will also be no heat damage to any surface since the heat travels upwards.
