Panel radiator Kermi FKO33 400×2000 mm C33 steel 2631 W with wall brackets

Kermi FKO33 panel radiator with dimensions 400×2000 mm (height × length) is a steel convector radiator engineered for central heating installations. The C33 configuration combines two convector panels and multiple fins to provide a compact external profile while delivering a nominal heat output of 2631 W. The radiator is supplied with wall brackets for secure mounting and is intended for residential and commercial spaces where efficient room heating from a slim panel unit is required.

Advantages

The steel construction ensures stable thermal conductivity and long service life under normal heating system conditions. The C33 panel arrangement increases surface area for effective convective heat transfer without significantly increasing thickness, allowing the unit to fit into tighter spaces compared with bulkier radiators. Supplied wall brackets simplify installation and provide robust support for a radiator of this length. The product’s nominal output of 2631 W makes it suitable for larger rooms or areas with higher heat demand.

Suitable for

• Heating of medium to large living rooms and open-plan spaces
• Heating of office areas, corridors and commercial rooms
• Replacement of older panel radiators in existing central heating systems
• Installations where a slim radiator profile and high output are required

Key specifications

• Construction material: steel panel with convector fins
• Type: C33 (double panel with convector fins)
• Height × length: 400 × 2000 mm
• Nominal heat output: 2631 W (conditions per manufacturer rating)
• Mounting: wall-mounted using supplied brackets

How to use

Connect the radiator to the building’s central heating circuit following the system designer or installer instructions. Ensure correct orientation and secure attachment to the wall using the supplied brackets and appropriate fixings for the wall material. Bleed the radiator after filling the system to remove trapped air and verify correct flow and return connections. Commission the radiator together with the heating system controls and thermostatic valves as required to obtain the rated heat output.

Usage recommendations

Use corrosion-inhibited water and follow local standards for system filling and maintenance. Periodic visual inspection of wall fixings and valve connections is recommended. For accurate sizing and balanced system operation, consult a heating professional to confirm radiator placement, pipework, and control settings.
