Heating radiator Purmo C33 model F063305009010300 — 500x900 mm, 1832 W output

Purmo C33 model F063305009010300 is a convective panel radiator designed for efficient heat delivery in residential and light commercial interiors. The unit has a double steel panel construction with three convector fins (C33), producing a rated output of 1832 W at standard test conditions. The radiator measures 500 x 900 mm and is intended for wall-mounted installation within central heating systems, offering compatibility with standard pipe connections and conventional thermostatic or manual valves.

Advantages

The C33 design combines two flat panels and three convector elements to increase heat transfer surface area while maintaining a compact depth. Its steel construction provides consistent thermal performance and reliable mechanical strength. The radiator's size and output make it suitable for rooms that require a moderate to high heat output in a relatively small footprint. Compatibility with standard mounting brackets and valve fittings simplifies installation and integration into existing heating circuits.

Suitable for

• Living rooms, bedrooms and hallways in apartments and houses
• Offices, small commercial spaces and consultation rooms
• Rooms requiring wall-mounted, space-saving heating solutions
• Replacement of older panel radiators with similar connection and mounting arrangements

When it may not be suitable

This radiator may not be suitable for very large or industrial spaces where much higher outputs or specialized heating solutions (e.g., fan-assisted or radiant panels) are required. It is also not intended for use outside of closed central heating systems or in installations where alternative fuels or heat sources incompatible with standard steel radiators are used.

Key specifications

• Type: double panel with triple convector (C33)
• Nominal heat output: 1832 W (at standard test conditions)
• Dimensions (HxW): 500 x 900 mm
• Mounting: wall-mounted with standard brackets
• Connection: standard pipe connections suitable for central heating valves
• Material: steel panels with convector fins

How to use

Install the radiator on a load-bearing wall using the appropriate brackets and fixings, ensuring correct alignment and sufficient clearance from the floor and surrounding objects. Connect to the central heating circuit using compatible inlet and outlet valves, bleed the unit to remove trapped air, and check for leaks. Adjust the room temperature with a thermostatic or manual valve according to the system design. Routine operation requires periodic venting and occasional surface cleaning to maintain heat transfer efficiency.

What to consider before purchase

• Confirm the required heat output for the room using heat loss calculations or professional advice
• Verify wall strength and available mounting space for a 500 x 900 mm unit
• Check compatibility with existing valve type and pipe spacing
• Consider finish, paint color, and any cover or grille if aesthetic integration is important

Usage recommendations

For optimal performance, install the radiator at the recommended height above the floor, avoid obstructing the front panel with furniture or curtains, and use a thermostatic valve to maintain stable room temperatures while saving energy. Regularly bleed the radiator after the heating season start and keep the convector fins clear of dust to preserve rated output.
