Radiator Stelrad Accord VK Type 20 600 x 600 mm — 499 W heat output (AV20/60/060)

The Stelrad Accord VK Type 20 radiator in size 600 x 600 mm delivers a rated heat output of 499 W and is designed for use in central heating systems. This double-panel, convector-style panel radiator combines a flat front plate with internal convector fins to transfer heat efficiently into living spaces. It is suitable for standard domestic and light-commercial installations where a compact, wall-mounted heating unit is required.

Advantages

The radiator provides a reliable heat output of 499 W at the stated dimensions, offering stable room temperature control without occupying significant space. Its double-panel construction with convector elements increases the heat exchange surface compared with a single panel, improving energy transfer. The unit is compatible with common connection positions and with modern central heating systems, making installation and replacement straightforward in many homes and offices.

Suitable for

• Heating living rooms and bedrooms in apartments or houses
• Small to medium-sized office spaces and meeting rooms
• Renovation projects replacing standard panel radiators
• Applications where a compact wall-mounted radiator with moderate heat output is needed

When it may not be suitable

This radiator may not be adequate as the sole heat source for large or poorly insulated rooms, where higher output or additional heating units would be required. It is a panel radiator designed for central heating systems and is not suitable for electric-only heating or off-grid installations without an appropriate boiler and distribution system.

Key specifications

• Type: Double-panel convector (Type 20)
• Dimensions (HxW): 600 x 600 mm
• Heat output: 499 W (rated output at standard test conditions)
• Mounting: Wall-mounted
• Material: Steel panel with convector fins
• Connection: Standard pipe connection positions for central heating

How to use

Install the radiator on a prepared wall using appropriate brackets and fixings rated for the unit weight and wall material. Connect to the central heating pipework using the standard inlet and outlet positions, ensuring system isolation before making connections. After mounting and hydraulic connections, bleed trapped air from the radiator using the bleed valve, and check for leaks. Adjust the room thermostat or radiator valve to achieve the required room temperature. Periodic maintenance includes bleeding air when necessary and checking for corrosion or paint damage.

What to consider before purchase

• Measure the available wall area and the radiator connections to confirm compatibility with 600 x 600 mm dimensions
• Verify that a 499 W output meets the room heat load calculated for the specific space and insulation levels
• Confirm that your central heating system uses compatible connection positions and supply temperatures
• Check wall strength and mounting options for safe installation

Usage recommendations

For best performance, size radiators to room heat loss and use thermostatic radiator valves and a properly balanced heating system to maintain consistent temperature and optimize energy use.
