Radiator Stelrad COMPACT type 11 600x400 mm — heat output 318 W

Stelrad COMPACT type 11 radiator, dimensions 600 x 400 mm with a rated heat output of 318 W, is a single-panel convector designed for wall-mounted central heating installations. Its compact profile fits installations with limited wall space while delivering reliable room heating. The radiator is compatible with standard pipe connections and can be used with thermostatic or manual valves to regulate room temperature.

Advantages

The single-panel convector construction offers a balance of efficient heat transfer and a slim front profile suited for tight installation spaces. Built from steel with a convector element, the radiator provides consistent heat output across typical domestic and light commercial environments. Compatibility with standard valves and pipework simplifies replacement or retrofit work, and the compact dimensions reduce the visual footprint on the wall.

Suitable for

• Residential rooms such as living rooms, bedrooms, and hallways
• Small commercial spaces and offices with central heating
• Rooms with limited wall depth where a slim radiator is required
• Retrofit projects replacing older radiators with standard connections

How to use

Install the Stelrad COMPACT radiator on a structurally sound wall using appropriate brackets and fixings for the given wall material. Connect to the central heating circuit using compatible pipe fittings and valves, ensuring correct inlet and outlet orientation. Bleed air from the radiator after filling the system to ensure full heat exchange. Adjust the room temperature using a thermostatic valve or the heating system controls according to comfort requirements. Follow local plumbing and heating codes and, if uncertain, use a qualified installer.

Usage recommendations

For optimal performance, size the radiator to the heat loss of the room and maintain clear airflow around the panel by avoiding covering the radiator with curtains or furniture. Periodic bleeding and inspection for leaks or corrosion will prolong service life. When replacing an existing unit, verify pipe centres and valve types to ensure a straightforward installation.
