Wolf NK/NU 20 oil/gas boiler, 17–20 kW

WOLF – premium German heating technology. The manufacturer from Mainburg produces boilers, controllers, and HVAC systems.

NK/NU 20 – 17–20 kW oil/gas boiler body. Identified based on the original data plate, the floor-standing appliance is designed for conventional central heating, with a suitable burner and controls.

• 17–20 kW heat output range: value from the data plate; the actual set output depends on the burner matching.
• 60 liters boiler water capacity: data for the specific version; the water capacity of another NK/NU unit is not applied to it.
• 3 bar permitted operating overpressure: the system pressure must be adapted to this.
• 110 °C permitted flow temperature limit: does not mean that the boiler must be operated continuously at this temperature.
• Oil/gas boiler body: gas operation requires a suitable gas burner; the boiler body designation does not prove the presence of two types of burners.

Documentation: the WOLF 30 43 000 factory steel boiler manual series material found; adaptation to the specific version and burner is required. The factory series manual is available online. The scope of delivery for the burner, controller, pumps, and hot water storage tank is defined in the specific offer.
