Floor-standing heating systems for gas and oil
Weishaupt Thermo Unit

Oil condensing equipment

Economic, quiet, environmentally-friendly: Weishaupt oil condensing systems for steel and cast iron boilers take the heat energy contained in the combustion flue gases and feed it to the heating circuit. The effect is that your heating oil requirement drops noticeably. At the same time, emissions are significantly reduced. The flue gas condenses and is drained into the waste water system. The remaining flue gas can escape via inexpensive plastic pipes.


  • Excellent nominal efficiency: The energy utilisation is approx. 102 percent Hi (96.2 % Hs).
  • Lower energy consumption: You will save heating energy and thus cash thanks to the improved fuel utilisation.
  • Lower emissions: The emissions are also lower thanks to the reduced energy consumption.
  • Silent operation: The Weishaupt condensing module reduces the noise output of the heating system.
  • Easy installation: The condensing module fits all Weishaupt oil boilers thanks to Weishaupt system engineering.
  • Inexpensive flue cleaning: Low-cost plastic rods are sufficient due to the low flue gas temperatures.
  • Long life: High-quality materials, such as the ceramic heat exchanger in the condensing module, guarantee long system life.
  • Fuel: Weishaupt oil and dual fuel burners are suitable for use with fuel oil EL and low sulphur fuel oil EL to DIN 51603-1, as well as fuel oil EL with additives of up to 10 % bio components to DIN 51603-6, fuel oil EL A Bio 5 and 10.
