The innovative integrated two-stage blue burner concept with speed-controlled fan also optimises comfort - the boiler output is automatically adjusted to the heat requirement via the two load stages. This saves energy, reduces the number of burner starts and minimises noise emissions. The quiet operation is supported by an air exhaust system and internal boiler sound insulation. The blue rim technology enables almost soot-free combustion and thus ensures consistently high efficiency. Thanks to its efficient operation, STRATON® ST promotes economical oil consumption. Its powerful controller also offers the option of efficiently integrating other components - such as a solar thermal system, a domestic hot water heat pump or a buffer cylinder for a wood boiler - into an energy-saving overall control concept. It is suitable for low-sulphur bio heating oil and low-sulphur EL heating oil.
Compact & modern design
A width of 0.5 m and a installation area of 0.4 m² (excl. required maintenance area) enable installation even in small rooms. The pump group design is harmonised with the boiler and fits perfectly into any room design.
Lower energy costs
STRATON® ST is designed to minimise consumption and fully utilise the heat from every drop of oil. The speed-controlled fan also results in significant savings in electricity consumption compared to conventional fans.
Lower emissions
Sustainability is not only achieved by using the latest technologies and saving energy. The possible use of renewable fuels also contributes to the reduction of hazardous emissions.
High-quality materials
Only the highest quality materials are used in all sizes of the STRATON® ST. One example of this is the corrosion-resistant stainless steel boiler shell. The STRATON® ST stands for a long lifespan and maximum reliability.

TO OUR REFERENCESHydraulic connection group
Customised connection groups are available for mounting the heating circuit pumps behind or to the side of the boiler.
Control accessories
A room temperature sensor also enables convenient operation of the control system from the living room.
Boiler pedestal
The boiler platform, consisting of a galvanised steel support plate with PU rigid foam lining (CFC-free), reduces the transmission of structure-borne noise to the foundation and the building.
Silencer
The operating noise of the already quiet STRATON® ST can be further reduced by using a customised exhaust gas silencer or muzzle silencer..
