Radiator Stelrad RENO COMPACT typ 22 550×400 mm, heat output 646 W (MPN RC22/55/040)

The Stelrad RENO COMPACT radiator type 22, size 550×400 mm, is a panel radiator designed for central heating systems. With a rated heat output of 646 W, this compact unit combines a double convector construction and a flat front panel to deliver efficient heat transfer in limited spaces. It is intended for wall-mounted installation and suits both retrofit projects and new heating schemes where a compact footprint and reliable performance are required.

Advantages

The double convector design increases the surface area for heat exchange, improving warm-air circulation compared with single-panel units. Its compact dimensions make it suitable for rooms with limited wall space while still delivering significant heat output. The flat front panel and clean lines offer a low-profile appearance that integrates with different interior styles. The radiator is factory-finished to resist corrosion and facilitate straightforward installation and maintenance.

Suitable for

• Residential rooms such as living rooms, bedrooms and hallways requiring compact wall-mounted radiators
• Small commercial spaces and offices where a discreet heating unit is needed
• Retrofit projects replacing older radiators with a more compact modern unit
• New build installations with limited wall area or where precise room heating is required

Key specifications

• Type: double convector panel radiator (Type 22)
• Height × Width: 550 × 400 mm
• Rated heat output: 646 W (performance at standard test conditions)
• Wall-mounted configuration with standard inlet/outlet connections
• Flat front panel with integrated convectors for improved heat distribution
• Construction: steel panels and convector fins designed for central heating systems

How to use

Install the radiator on a suitable load-bearing wall using appropriate brackets and fixings, ensuring correct alignment and clearance from floor and furniture for effective convection. Connect to the central heating circuit following local plumbing codes and system layout, observing the correct flow and return pipe positions. Bleed air from the radiator after filling the system to remove trapped air and verify the unit reaches operating temperature. Regularly check valves and pipework connections for leaks and ensure the unit is compatible with the system water treatment and pressure.

Usage recommendations

For consistent performance, balance the heating system after installation and perform periodic bleeding to maintain heat output. Keep the front panel clear of large obstructions to allow free airflow. Use corrosion-inhibiting additives in the system water where recommended by the heating engineer and follow local installation standards for valve selection and mounting height.
