4. Setup and Installation
For detailed and specific installation instructions, please refer to the official Hudson Reed Installation Manual PDF available for download or included with your product. Professional installation is highly recommended.
General Installation Steps:
- Unpacking: Carefully remove the radiator and all components from the packaging. Inspect for any damage.
- Location Selection: Choose a suitable wall location, ensuring it can support the weight of the radiator when filled with water. Consider proximity to existing pipework.
- Marking and Drilling: Using the provided technical drawing and mounting brackets, mark the drilling points on the wall. Drill holes and insert rawl plugs.
- Mounting Brackets: Securely attach the wall mounting brackets to the wall using the provided screws.
- Radiator Mounting: Carefully lift and position the radiator onto the mounted brackets. Ensure it is level and secure.
- Pipe Connection: Connect the radiator to your central heating system pipework. Ensure all connections are watertight.
- Blanking Plug & Bleed Valve: Install the blanking plug into one of the top ports and the bleed valve into the other top port.
- System Filling & Bleeding: Slowly fill your heating system, then open the bleed valve on the radiator to release trapped air until water starts to emerge. Close the valve immediately.
- Leak Check: Thoroughly check all connections for leaks.

5. Operating Instructions
Once installed and connected to your central heating system, the radiator operates in conjunction with your boiler and thermostat. There are no direct controls on the radiator itself beyond the bleed valve and any manual or thermostatic radiator valves (TRVs) you may have installed.
- Turning On/Off: The radiator will heat up when your central heating system is active and the radiator valves are open. To turn off heat to a specific radiator, close its manual or thermostatic valve.
- Temperature Control: If you have TRVs installed, you can adjust the heat output of individual radiators by rotating the TRV head to your desired setting.
- Bleeding the Radiator: If the top of the radiator feels cold while the bottom is hot, it likely has trapped air. Use a radiator key (not included) to open the bleed valve slightly until air escapes, followed by water. Close the valve immediately. Perform this annually or as needed.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your radiator.
- Cleaning: Clean the radiator regularly with a soft, damp cloth. For stubborn marks, use a mild, non-abrasive detergent. Avoid harsh chemicals or abrasive cleaning tools, as these can damage the finish. Ensure the radiator is cool before cleaning.
- Annual Bleeding: Bleed your radiators at least once a year, typically before the heating season begins, to remove any trapped air and ensure efficient heating.
- Pressure Check: Periodically check your central heating system's pressure gauge. If the pressure is too low, repressurize the system according to your boiler's instructions.
- Leak Inspection: Regularly inspect all pipe connections and the radiator body for any signs of leaks. Address any leaks immediately to prevent water damage.
7. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator cold at the top, hot at the bottom | Trapped air | Bleed the radiator using a radiator key until water emerges. |
| Radiator completely cold |
