Obviously, it is much more difficult to manufacture tile stove inserts from cast iron, the most durable material used in heating technology. Its main advantage is the almost strainless and torsion-free combustion chamber construction, which is able to withstand the highest thermal loads, but it's also a long-lasting solution, ensuring decades of safe operation. Problems caused by scaling, which is typical for ordinary steel, and the resulting limitation of lifetime is unknown for iron castings.
Design highlights of modern tile stoves (HKD series)
Combustion quality:
BRUNNER is considered as the pioneer of low-emission combustion of wood in tile stoves and fireplaces. The basic principles, developed since 1989:
* closed firebox without grate
* deflecting element with flame channel
* isolated afterburning chamber
are continuously improved and maintained until now. This low-emission technology is described as the 'ISO combustion chamber'. In combination with electronic control systems it is possible to prevent faulty operation and ensure unmatched combustion quality and a maximum of convenience during use. HKD inserts are suitable for heat storage solutions with attached or top-mount accumulation blocks, and come with a self-closing door provided for multiple connection with a single chimney only.
Design highlights of traditional tile stoves (HBO series)
During combustion of wood hot gases are produced. These gases are not led away straight to the atmosphere, but instead they are streaming through attached heat collectors (for example a ceramic duct) while giving the heat off. The HBO series is intended for use with ceramic heat storage, which is keeping the stove warm for many hours. This internal "core" is giving off heat to the external shell of stove, which in turn makes the room warm. Individual characteristics of the heat collector and the external stove shell decide finally about the specific heat output of a tile stove.
