Floor standing oil condensing system
Weishaupt Thermo Condens WTC-OW Compact

Efficient, compact and silent

The floor standing Weishaupt Thermo Condens Compact for oil, WTC-OW K, combines modern oil condensing technology with efficient storage technology. Because of its modulating operation, the WTC-OW K is particularly quiet in operation and is very economical in its use of fuel oil. The integrated domestic water tank works as efficiently as a larger one, but requires no additional space.


  • Best energy utilisation: The modulating operation uses very little fuel for high efficiency.
  • Economical and quiet: The innovative premix oil burner ensures quiet and low emission operation.
  • Reliable heat transfer: The heat exchanger made of aluminium/silicium has proven itself as an excellent heat conductor.
  • Simple operation: The WTC-OW K can easily be controlled by a remote control station.
  • Continuously economical: The inbuilt energy reducing pump fitted as standard reduces electrical consumption
  • Less space required: The WTC-OW Compact require little floor space - thanks to the integrated tank.
  • Innovative stratified storage: The new Weishaupt Aqua Power (115 litres) is small and requires little space. However, it offers all the convenience of a larger, 200 litre tank.
  • Economic alternative: The WTC Compact is also available with a proven 100 litre coil heat exchanger, the Weishaupt Aqua Integra.
  • Fuel: The WTC-OW is designed for use with low sulphur fuel oil EL (DIN 51603-1).
