Radiator side connect Sourcing 33PKKPKP 500x900 — panel radiator, side inlet, model 33

The Sourcing 33PKKPKP 500x900 side connect panel radiator is a double convector heating element designed for central hydronic systems. With its side inlet configuration and model 33 construction, the radiator delivers increased heat output compared with single-panel units while maintaining a compact profile suitable for wall mounting in residential and commercial interiors.

Advantages

This model offers higher thermal performance due to its double convector panel design, providing more efficient heat transfer and faster room warm-up. Side inlet piping allows flexible installation in rooms where floor-level connections are not practical. The panel construction ensures a flat, unobtrusive appearance that integrates with modern interiors and is compatible with standard central heating systems.

Suitable for

• Heating living rooms, bedrooms and offices in residential buildings
• Small to medium-sized commercial spaces such as reception areas or meeting rooms
• Retrofit or new-build projects with side inlet piping arrangements
• Applications requiring higher output from a compact wall-mounted radiator

When it may not be suitable

The side inlet configuration may not be ideal where only bottom-connection piping is available or preferred; in such cases an alternative radiator with bottom connections would be more appropriate. This panel radiator is designed for hydronic central heating and is not suitable for electric-only heating systems without additional equipment.

Key specifications

• Type: Panel radiator with double convector (model 33)
• Connection position: Side inlet
• Dimensions (HxW): 500 x 900 mm
• Mounting: Wall-mounted
• Application: Central hydronic heating systems

How to use

Install the radiator on a suitably reinforced wall using brackets compatible with the 500 x 900 mm panel size, and connect the side inlet to the central heating pipework following local plumbing codes. Bleed the radiator after filling the system to remove trapped air and check for leaks. Set the system controls and thermostatic valves (if fitted) to regulate room temperature; periodic maintenance such as flushing the system and checking for corrosion will help maintain performance.

What to consider before purchase

• Confirm your heating system uses side inlet connections or that piping can be adapted for side connection
• Verify radiator dimensions to ensure fit on the intended wall and clearance for mounting
• Ensure compatibility with your central heating system pressure and flow characteristics
• Decide whether thermostatic valves or additional accessories will be required

Usage recommendations

For optimal performance, install this Sourcing panel radiator at least 10–15 cm above the floor and allow unobstructed airflow around the panel. Use a thermostatic radiator valve to balance comfort and energy efficiency, and perform regular system maintenance including periodic bleeding and water quality checks.
