Overview of low temperature boilers for oil with more than 400 kW

Large buildings usually have a comparatively high heat demand. This can be covered economically and reliably with a low temperature oil boiler from Viessmann. In addition to oil condensing boilers for detached and two-family houses, Viessmann also offers oil boilers with proven non-condensing technology in the output range from 400 to 2000 kW –– in the usual Viessmann quality with high operating convenience. Whether for a large residential, commercial or industrial property; new build or a modernisation project: the Viessmann portfolio has the right low temperature oil boiler for every application. 

Vitorond 200: flexible construction thanks to sectional design

Another low temperature oil boiler for use in buildings with large heat demands is the Vitorond 200. It has a sectional design and is used when the available space makes it difficult or even impossible to install a storage combi boiler. Due to its design, it can be disassembled into individual parts (cast sections) and easily assembled on site using a compression tool. The Vitorond 200 is particularly suitable for use in older buildings, where space is often tight. Despite the sectional design, this low temperature oil boiler covers output ranges from 440 to 1080 kW and also comes factory-fitted with the Vitotronic control unit.

With its multi layered convection heating surfaces made from specially folded triplex pipes, the Vitoplex 300 three-pass boiler offers particularly economical, clean and reliable operation. Thanks to their design, the heat conducting steel pipes that are inserted one inside the other have a heating surface that is 2.5 times larger than that of smooth pipes. They are also constructed in such a way that the surface temperature remains above dew point during heat transfer. This prevents condensate formation and corrosion damage.

Easy handling for installation and maintenance

The Vitoplex 300 also features the integral Therm-Control start-up system. This replaces the shunt pump or continuous return temperature raising facility, which saves installation time and costs. Low temperature oil boilers with a rated heating output of more than 620 kW are equipped with a walk-on boiler cover to facilitate installation and maintenance. The Vitoplex 300 is controlled via the easy to use Vitotronic control unit with colour touchscreen.

Vitoplex 200: non-condensing oil boilers for different requirements 

The Vitoplex 200 can be used as an alternative to the Vitoplex 300. This compact low temperature oil boiler made of steel has a rated heating output of 440 to 1950 kW and can be used with a wide range of burners. In versions up to 560 kW, the Vitoplex 200 also has the Therm-Control start-up system. A walk-on boiler cover is provided for 700 kW boilers and above. The Vitoplex 200 achieves a standard seasonal efficiency [to DIN] of up to 89 percent with fuel oil. It is easy to operate via the Vitotronic digital control system with communication capability and enables complete integration into building management systems.
