Large buildings typically have relatively high heating requirements. This can be met economically and reliably with a low-temperature oil boiler from Viessmann. In addition to condensing boilers for detached and semi-detached houses, Viessmann also offers oil boilers with proven non-condensing technology in the 400 to 2,000 kW range – all in typical Viessmann quality and with high ease of use. Whether it’s a large residential, commercial, or industrial property, a new build or a modernization project: Viessmann has the right low-temperature oil boiler for every application.
Another low-temperature oil boiler for use in buildings with high heating requirements is the Vitorond 200. It features a sectional design and is used in situations where space is limited and installing a storage combi boiler is difficult or even impossible. Thanks to its design, it can be disassembled into individual parts (cast sections) and easily reassembled on-site using a compression tool. The Vitorond 200 is particularly suitable for use in older buildings where space is often at a premium. Despite its sectional design, this low-temperature oil boiler covers output ranges from 440 to 1080 kW and is factory-fitted with a Vitotronic control unit.

Thanks to its multi-layer convective heating surface made of specially folded three-layer tubes, the Vitoplex 300 three-pass boiler ensures particularly economical, clean, and reliable operation. Due to their design, the heat-conducting steel tubes, inserted one inside the other, have a heating surface 2.5 times larger than smooth tubes. Furthermore, they are constructed so that the surface temperature remains above the dew point during heat transfer. This prevents condensation and corrosion.
The Vitoplex 300 also features the integrated Therm-Control startup system. This replaces a shunt pump or continuous return temperature booster, saving installation time and costs. Low-temperature oil boilers with a rated output of over 620 kW are equipped with a boiler cover, simplifying installation and maintenance. The Vitoplex 300 is controlled by the easy-to-use Vitotronic control unit with a color touchscreen.
The Vitoplex 200 can be used as an alternative to the Vitoplex 300. This compact, low-temperature oil-fired boiler made of steel has a rated 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 is also equipped with the Therm-Control start-up system. A boiler cover is available for boilers with an output of 700 kW and above. The Vitoplex 200 achieves a standard seasonal efficiency (DIN) of up to 89 percent when running on oil. It is easy to operate with the Vitotronic digital control system with communication capabilities and allows full integration into building management systems.
Geothermal collectors for brine/water source heat pumps extract heat close to the surface and can be installed without a permit. You can read more about the differences here.
