Radiator Stelrad COMPACT 22 model C33/60/120 — 2867 W heat output, 600×1200 mm

Radiator Stelrad COMPACT 22 model C33/60/120 is a panel radiator designed for central heating systems. With a nominal heat output of 2867 W at standard test conditions and dimensions of 600 × 1200 mm, this double-panel, double-convector unit provides a balance of convective and radiant heating suitable for residential and light commercial interiors. The radiator accepts standard side or bottom plumbing connections and is intended to be used as a primary room heat source in living rooms, offices, hallways and similar spaces.

Advantages

The double-panel, double-convector design increases heat output within a compact depth while maintaining a flat, finished front panel that integrates with common interior styles. Its rated output of 2867 W makes it effective for medium-sized rooms when installed according to system flow temperatures and room calculations. Compatibility with standard connection types simplifies installation into existing central heating circuits, and the panel construction offers predictable, uniform heat distribution across the radiator surface.

Suitable for

• Primary heating in living rooms and family areas
• Office rooms and small commercial spaces
• Hallways, corridors and circulation areas
• Replacement of similarly sized panel radiators in central heating systems

When it may not be suitable

This radiator may not be suitable where very high heat output is required beyond its 2867 W rating, such as large open-plan areas or poorly insulated spaces without additional heating. It is not designed for direct use with non-standard heating fluids or for standalone electric heating; it requires a compatible central heating system and appropriate system water temperatures to achieve the stated nominal output.

Key specifications

• Heat output: 2867 W (nominal, standard test conditions)
• Dimensions (HxW): 600 × 1200 mm
• Construction: double-panel, double-convector
• Connection options: standard side or bottom plumbing
• Intended use: central heating systems for residential and light commercial rooms

How to use

Install the Stelrad COMPACT 22 model according to the manufacturer’s mounting instructions and local plumbing codes, ensuring secure wall fixings that support the radiator weight when filled with water. Connect to the central heating circuit using the chosen side or bottom connection points; purge air from the unit after filling and balance the system to achieve correct flow through the radiator. Operate as part of the building’s central heating, controlling room temperature via the system’s thermostat or a thermostatic valve fitted to the radiator.

What to consider before purchase

• Confirm the radiator dimensions (600 × 1200 mm) fit the available wall space and mounting points.
• Verify the 2867 W nominal output aligns with room heat loss calculations for your space.
• Ensure your central heating system plumbing is compatible with standard side or bottom connections.
• Check required wall fixings and support capacity for the filled radiator weight.

Usage recommendations

For reliable performance, install and commission the radiator with proper system balancing and an appropriate thermostat setting. Regularly bleed the radiator to remove trapped air and perform periodic visual inspections for secure mountings and connection integrity. Match the radiator selection to calculated room heat losses and maintain the central heating system to preserve the rated output of 2867 W.
