Radiator Stelrad Novello Type 33 600×400 mm — heat output 771 W

Stelrad Novello Type 33 panel radiator, size 600×400 mm, offers a rated heat output of 771 W. Designed for wall-mounted installation in central heating systems, this Type 33 convector radiator features three panels and three convector fins to increase heat transfer within a compact footprint. Its dimensions make it suitable for standard domestic and light commercial rooms where efficient, even heating and straightforward installation are required.

Advantages

The panel-convector construction provides a higher surface area for convection and improved thermal performance compared with single-panel radiators of similar size. The radiator’s slim depth and compact height allow flexible placement on walls, making it appropriate for retrofit projects and new installations where space is limited. Robust steel construction and factory-applied finish ensure long service life and ease of maintenance.

Suitable for

• Living rooms and bedrooms in residential properties
• Bathrooms and hallways (with appropriate valves and controls)
• Small to medium-sized offices and commercial rooms
• Replacement of existing radiators in retrofit projects

How to use

Install the Stelrad Novello Type 33 on a prepared wall using the manufacturer’s recommended bracket positions and mounting hardware. Connect the radiator to the central heating system using compatible valves and fittings, ensuring correct orientation for side or bottom connections as required. Bleed the radiator after filling the system to remove trapped air and check for leaks. Set the room thermostat or TRV to the desired temperature; the radiator will transfer heat via convection and radiation to maintain ambient warmth.

Usage recommendations

For optimal performance, ensure pipework and system pressure are compatible with the radiator and follow recommended commissioning procedures. Use thermostatic radiator valves to control temperature room by room, regularly bleed the radiator to maintain efficiency, and avoid obstructing the front and top surfaces to allow free airflow around the convector fins.
