## Long description

Stelrad Compact C21 600×800 mm is a two-panel, one-convector panel radiator designed for central heating systems. With a nominal heat output of 866 W, this wall-mounted radiator provides steady room heating for residential and commercial spaces. The Compact C21 construction combines a double steel panel with a single convector to balance efficient heat transfer and a compact depth suitable for replacements or new installations where wall space is limited.
Advantages
The radiator offers reliable thermal performance with a clear rated output of 866 W for sizing and energy calculations. Its compact profile reduces projection from the wall, helping to save space without sacrificing heat delivery. Constructed from steel panels with integrated convector fins, the unit provides stable convective and radiative heating and is compatible with standard central heating pipe connections. The design supports straightforward wall mounting and is suitable for typical domestic and light commercial installation environments.
Suitable for
 Heating living rooms, bedrooms and bathrooms in apartments and houses
 Providing space heating in offices, meeting rooms and small commercial spaces
 Replacement of existing panel radiators with similar mounting and connection arrangements
Key specifications
 Dimensions: 600 × 800 mm (height × width)
 Rated heat output: 866 W (nominal output at standard test conditions)
 Construction: two steel panels with one convector (C21)
 Mounting: wall-mounted installation
 Connection: standard central heating pipe connections (side or bottom options depending on installation accessories)
 Finish: factory-coated steel surface suitable for indoor environments
How to use
Install the radiator on a suitably prepared wall using appropriate brackets and fixings. Ensure the central heating system is isolated and drained as required before disconnecting or connecting pipework. Position the unit at the correct height to allow for valves and bleed access. After secure mounting and connection, refill and purge the system to remove air, then check for leaks and confirm correct operation at normal system pressure and temperature.
Usage recommendations
For accurate room sizing, use the stated rated output (866 W) together with room heat loss calculations and consider placement to avoid furniture blocking the radiator. Use compatible valves and fittings, follow local plumbing regulations, and have installation or replacement performed by a qualified technician to ensure safe and efficient operation.
