good thermal performance, a smooth surface and a high degree of strength which guarantees a long service life. The JAcobus is of such high quality that we give you a lifetime guarantee on this wood stove.


Friendly for the environment A comfortable way of life is largely determined by a pleasant temperature. One of the most environmentally friendly ways to heat a home is with a Jacobus wood stove, certainly when the stove is operated correctly. Wood is a nonfossil natural product which makes it an eco-friendly source of energy. Wood burning is carbon neutral. Moreover, the JAcobus meets the strictest European environmental standards. In short: if you want to combine comfort with dealing responsibly with the environment, you have made a sensible choice with a JAcobus wood stove.


The JAcobus summarized • The JAcobus is an ultra-clean stove with a revolutionary, patented combustion technology. • The JAcobus combustion chamber is made of heat-resistant corten steel and ensures proper heat conduction and a long service life. • The supply of heat is easily managed, so the stove is suitable for small or large spaces. • As standard, the JAcobus provides the option of being able to conduct the combustion air from outside and this is why it is also suitable for (well-insulated) newly-built homes. • The stove features a handy one-button control that maintains the correct balance among the primary, secondary and tertiary (combustion) air being supplied. • Thanks to its unique combustion system, the emission of particles is extremely low and the glass pane remains clean.

JAcobus Versatile The JAcobus is a convection stove. This means that the stove optimally distributes warmth throughout a space. Furthermore, the JAcobus is available in three versions with different capacities. You can customise the output according to your wishes. For example, the JAcobus 6 can produce a yield ranging from 3.5 to 7 kW, the JAcobus 9 from 5 to 10 kW and the JAcobus 12 from 7 to 14 kW. Each model is equipped with an upper and a rear connection. Moreover, the JAcobus has the option for external air supply, which makes the stove ideal for well-insulated, (newly built) homes. As standard, the stove is sand blasted and painted with anthracite black heat resistant enamel. A JAcobus wood stove with a self-closing door is also available upon request.


JAcobus 6 The smallest JAcobus has a capacity ranging from 3.5 kW to 7 kW and heats spaces to approximately 120 m3. The mini not only delivers comfort and cosiness, but also enough heat output for most (living) rooms.

JAcobus 9 The JAcobus 9 is the middle model with regards to capacity that will fit in almost every living room. The output can easily be determined and varies from 5 to 10 kW. This means that the JAcobus 9 is suitable for rooms up to 160m3.

JAcobus 12 The largest JAcobus is ideally suited to burn large blocks of wood. With a capacity range from 7 to 14 kW, the JAcobus 12 is perfect for heating a larger than average living room or other spaces up to 250m3.

JAcobus cook Cooking the old-fashioned way A good wood burning stove gives off so much heat that it seems a shame to use it purely for heating your home. That is why Janco de Jong has developed a special cooking stove: a JAcobus wood-burning stove with three stainless steel cooking plates plus an extra protective rim around the stove. You can even mount the JAstoof, an oven, on the stove pipe, meaning you can bake as well as cook and fry. Inside or in a covered courtyard. The JAcobus cook is (just like the JAcobus) available in three capacities and all three models are equipped with an upper or rear connection.


JAcobus see-through View from two sides The latest version of the durable JAcobus wood stove is specially designed at the request of our clients: the JAcobus see-through. This stove has the same characteristics as the other JAcobus models but features a glass window on both sides. This enables you to place the stove in the middle of a space where you can optimally enjoy the flaming spectacle inside the stove. The JAcobus see-


through is (just like the JAcobus) available in three capacities.


JAcobus concrete Warm even longer The JAcobus concrete is a unique looking stove with excellent heat conduction and optimal heat storage. The heart of the JAcobus concrete has the same combustion chamber as the other JAcobus stoves. Surrounding it, is a coat of light grey cast concrete. The stove does not only provide heat by way of convection but also by radiating. That ensures a constant and long-lasting supply of heat. Twice as effective and comfortable too! The concrete on the outside has also been treated in such a way that the surface is smooth and most importantly, maintenance-free. The JAcobus concrete is available in capacities of 6, 9 and 12 kW and is equipped with an upper and rear connection.
