To add a bit of colour to our BioFire Fireplaces we use a special mineral based pain. Keim Paints supplies this universal, easy to use,interior, mineral, silicate based paint. Keim Paint is environmentally safe and harmless to the decorator. It has an anti–condensation coating and does not give off chemical fumes as normal paint would. This paint can withstand high temperates and will not crack when the surface gets hot.

Here are a few important facts about Keim Paint:

Envirometally friendly: it is water based,no plasticiser or biocicides, no solvents and contains mineral ingredients.

Comfortable room climate: it is non flamable, breathable and prevents mould and algal growth.

Practical and cost effective: it is economical, ready to use, longlife and colorfast.

A BioFire fireplace is not only a heating solution, but also an economically friendly fireplace. By using this special mineral base paint, we are adding the extra “green” touch.

After the outer layer of a BioFire fireplace has been completed, it is then plastered with a special heat resistant plaster. This plaster is certified and tested in regards to the absence of any harmful chemicals. This is important as the surface area of a “Masonry Heater” or “Kachelofen” such as a BioFire fireplace reaches a temperature of 60 Degrees Celsius. It is the plastered surface that provides heat for many hours after the fire is gone.

Here are a few facts about the plaster we use:

• 100% biological
• Heat and crack resistant
• Comes out as a pure white
• Plastered in two layers, first rough and then fine
• Does not require painting, but can be painted with mineral based paint.

Ceramic Refractory Bricks

Each BioFire fireplace is built using high quality ceramic refractory bricks . These store the heat for long after the flames are gone and gradually radiate heat to keep your home nice and warm.

A BioFire fireplace weighs anything between 800 and over 2.500kg. The weight very much depends on the amount of ceramic refractory bricks needed to store sufficient energy in order to radiate heat for an extended period of time. While some other fireplaces might have additional weight added to their metal fireboxes in the form of ceramics it is still not possible to provide sufficient radiant heat from a structure weighing in at 250kg.

The patented BioFire refractory brick possesses several unique properties you will not find in any other masonry heater:

High pressure moulded and burned at 1.450° C

The added surface area facilitates long heat retention

The composition allows some moisture from wood to be absorbed

Integrated tongue and groove system ensures perfect adhesion

A BioFire refractory brick will look like new after 10 years of continuous use. Built once to last a lifetime

A masonry heater such as a wood burning BioFire fireplace is always built in two layers. First the ceramic inner core contain the calculated flue passages is constructed. One completed the second layer of outer ceramic refractory bricks is added. This layer ensures that a BioFire is the safest wood burning fireplace with children around. Additionally the comfortable heat is radiated from this surface area. See below how a semi-floating BioFire fireplace is constructed.

Instead of building a podium covering the entire base area of this closed combustion fireplace, a solid steel plate is placed on top of a reduced podium.

On this foundation the combustion chamber of the core is constructed. The special refractory bricks are held together using a fireproof cement and metal brackets. Furthermore the extremely durable bricks use a tongue and groove joining system for a better fit.

The core is finished off by adding the flue passages above the wood combustion chamber.

Before adding the outer layer of refractory bricks a test firing is performed to ensure perfect functioning.

Once satisfied that the fireplace is tight, the passages have been connected correctly and that the flue draws the outer layer is added.

This outer layer is then plastered to provide a clean and modern finish of this environmentally friendly heating solution.

A photo of the completed fireplace will be added to our Facebook page shortly. So make sure to follow us to see our latest projects.

The internal flue passages of a wood burning BioFire Fireplace are spcecially engineered and calculated for each individual fireplace.

The flue passages are designed according to the dimensions of the fireplace. If the dimensions are more narrow and high, the flue passages are located above the fireplace, if the dimensions are more wide, the flue passages are located on the sides of the fireplace.

The design of the flue passages will also determine the draft conditions of chimney.

Strong draft = narrower flue passages to slow down the flow inside the fireplace

Weaker draft = wider channels to speed up flow

Theses specially calculated flue passages allow for as much energy as possible to be absorbed into the core of the fireplace. The heat that is retained in the core of the fireplace provides radiant heat for 12- 24 hours, making a BioFire fireplace an efficient heating solution. Only masonry heaters like a BioFire will provide long lasting heat in this way.

Through its advanced engineering features we can guarantee that there is no smell of smoke and combustion gas inside your living space when using a BioFire fireplace. An important aspect in achieving this is the BioFire glass door which was developed over a decade ago and has been continuously improved ever since. This unique “fire window” is specially designed so that no smoke can escape into the room and will always ensure that no soot or dust can settle on the glass blurring your view of the fire.
