Radiator Stelrad COMPACT 33/500/1000 — output 2056W, model C33/50/100

Stelrad COMPACT 33/500/1000 is a panel radiator with a nominal heat output of 2056 W (model C33/50/100). It is designed for use in central heating systems and provides a compact profile suitable for residential or commercial interiors. The radiator features a three-panel, three-convector construction that increases heat transfer area while keeping overall depth moderate, and it is supplied with standard connection options to match typical plumbing configurations.

Advantages

The radiator combines a compact footprint with a high nominal output, allowing efficient space heating where wall space is limited. Its panel-and-convector design improves thermal performance compared with single-panel radiators while remaining compatible with conventional central heating systems. The unit’s standardized connection positions facilitate replacement of existing radiators or integration into new installations without requiring special adapters.

Suitable for

• Heating living rooms, bedrooms and hallways in residential properties
• Small to medium-sized offices and commercial rooms
• Replacement of existing panel radiators with similar connection layouts
• New installations requiring a compact radiator with specified heat output

Key specifications

• Nominal heat output: 2056 W (as specified for typical test conditions)
• Panel configuration: three panels with three convectors for enhanced heat transfer
• Height: 500 mm
• Width: 1000 mm
• Depth: compact profile suitable for standard wall mounting
• Connection type: standard central heating connections compatible with common plumbing layouts
• Material and finish: steel panel construction with corrosion-resistant coating (factory-applied finish)

How to use

Install the radiator on a load-bearing wall using appropriate brackets and fixings rated for the radiator size and local wall construction. Connect to the central heating system using the standard inlet and outlet positions; ensure all joints are properly sealed and system pressure is within manufacturer-recommended limits. After filling and venting the system, check for leaks and bleed the radiator to remove trapped air to achieve the stated heat output. Follow national plumbing and heating regulations and, where required, use a qualified installer.

Usage recommendations

Position furniture and coverings to allow unobstructed airflow across the radiator surface for best performance. Regularly bleed the radiator and maintain the central heating system to prevent loss of efficiency. When replacing an existing unit, verify that pipework alignment and bracket positions match the new radiator dimensions to minimise additional adjustments.
