Stone Oven Kit Ortner HBO 4
Stone oven from Austria
ORTNER offers wood-fired oven kits made from their high-quality cast chamotte in five different size models. The stone ovens made of fire concrete are suitable for private or commercial use; there's something for everyone. A special feature is the inner surface of the baking chamber, which, through its curved design, provides a larger surface area and can therefore radiate more heat.
Versatile Application
Whether as an integrated oven within a kitchen landscape or outdoors in a summery garden atmosphere, the ORTNER wood-fired oven leaves nothing to be desired in terms of versatility and design options. Roasting and baking become an experience again. Anyone who has experienced the wood-fired oven will be thrilled by the distinctive culinary delights and will want to experience the taste of wood fire again and again.
Construction and Materials
In contrast to electric ovens or those made of refractory brick, the ORTNER wood-fired oven is made of so-called fire concrete. The advantage lies in its efficient heat storage capacity. The heat from the fire is absorbed and stored throughout the entire baking chamber. The stored heat is radiated and distributed evenly throughout the oven for several hours. This is the perfect prerequisite for a successful cooking result.
Stone Oven Combustion Chamber Geometry
The special combustion chamber geometry ensures even heat distribution. Initially, the air begins to heat up and circulates evenly throughout the entire baking chamber. At the same time, heat is absorbed by the storage material and, after some time, radiated back inwards. The ceramic base plate also plays a crucial role. It must store heat for as long as possible, as there is direct contact with the food here. If the base plate cools down too quickly, it can negatively affect the baking process.
It Doesn't Get More Natural Than This
If you value nature and sustainability, an ORTNER wood-fired oven is the right choice. Even the durable material from which the oven itself is made – fire concrete – is produced from natural raw materials such as chamotte and clay. In addition, there's what truly defines a stone oven: heating with wood. Heating with wood is environmentally friendly, sustainable, and CO2-neutral.
Suitable for Private and Commercial Use
Whether for private or commercial use, indoors or outdoors, kitchen or garden. The various size models of the ORTNER wood-fired oven allow for a wide range of applications. The ORTNER wood-fired oven models 0 and 1 are perfectly suited for private use:
For commercial use, sizes model 2 to 4 are recommended.
