Floor station 

CAT

Innovation meets reliability

Floor stations are compact appliances that draw hot water from the heating circuit on demand and use it to heat drinking water directly at the draw-off point using a heat exchanger. In general, they provide efficient decentralised heat distribution and hygienic DHW heating. The new WOLF CAT-37/45/55 floor station can be connected to a variety of central heat generators and combines centralised convenience with decentralised DHW heating. Its most appealing feature is hot water at a consistent temperature thanks to the WOLF RatioFlow controller.

CAT37
CAT45
CAT55

The WOLF CAT floor station is available in 10 basic versions with or without a thermal insulation cover for 2-line systems – with extensive standard equipment and optional accessories.

  • CAT-HT version for high-temperature circuits in 3 DHW output ratings
  • CAT-LT with mixing circuit for low-temperature heating circuits including high-temperature connection in 3 DHW output ratings
