10-year warranty against severe corrosion

A completely new boiler technology was developed for the ROTEX A1 boiler unit. In doing so, we consistently used modern high performance materials and avoided corrosive materials such as black steel or cast iron.

The boiler unit itself is executed in die-cast aluminium. Stainless steel corrosion-resistant pipes in which the heating water flows are also directly cast into the unit.

The patented spherical shape of the boiler unit enables a compact design, unrestricted use of the condensing technology directly in the boiler without an additional heat exchanger as well as easy cleaning. Furthermore, the spherical structure allows good metal contact between the stainless steel combustion chamber and the cooling ribs of the boiler unit. This defines the combustion chamber's cooling process. This directly cooled combustion chamber is very effective in reducing the formation of nitrogen oxide (NOX).
