Radiator Stelrad COMPACT Type 22 600×400 mm — heat output 558 W

Stelrad COMPACT Type 22 panel radiator, size 600×400 mm, provides a rated heat output of 558 W for central heating systems. This double-panel radiator with two convectors is designed for wall-mounted installation in residential and commercial interiors. The construction offers a compact profile while delivering consistent convective and radiative heat suitable for retrofit or new-build installations, and it is compatible with standard pipe connections and common mounting accessories.

Advantages

The double-panel, two-convector design increases surface area for improved heat transfer while maintaining a slim depth for limited-space installations. Steel panel construction ensures even temperature distribution and stable performance over time. The radiator is finished for straightforward wall mounting and selectable connection orientations, making it adaptable to typical heating layouts. Its rated output of 558 W at standard test conditions provides a clear performance reference for sizing and room-heat calculations.

Suitable for

• Heating living rooms, bedrooms and small to medium-sized commercial spaces
• Retrofit projects replacing older radiators with a compact panel solution
• New-build installations where a slim profile and reliable output are required
• Standard central heating systems with common pipe connection arrangements

How to use

Install the radiator on a suitably reinforced wall using compatible brackets and fasteners. Ensure pipework is prepared for the chosen connection orientation and that system pressure and water quality meet heating system recommendations. After mechanical mounting and hydraulic connections, bleed any trapped air from the radiator and balance the system according to the installer’s procedure. Set thermostatic or manual valves as required to achieve desired room temperatures.

Usage recommendations

For reliable operation, follow professional installation practices: use appropriate wall fixings, verify system compatibility, carry out flushing and inhibitor dosing if required, and commission the system with correct balancing and venting. Regularly bleed radiators and check valves to maintain efficient heat output.
