FAQs

What is the heat output of this radiator?

This radiator provides a heat output of 360 W, which is equivalent to 1230 BTU.

Does it come with mounting brackets?

Yes, the radiator includes wall fixings, brackets, a bleed valve, and a blanking plug.

Is this radiator suitable for a bathroom?

While it is durable, this radiator is designed for general indoor use. Ensure it is placed away from direct water spray to protect the finish.

How long is the warranty?

Can I install this vertically?

What is the wall-to-centre distance?

The wall-to-centre distance for this unit is 50 mm.

Troubleshooting

Radiator is cold at the top

There is likely trapped air inside the system. Use the provided bleed valve to release trapped air until water flows steadily.

Radiator is cold at the bottom

This often indicates a sludge build-up or a flow restriction. You may need to power-flush the system or check if the valves are fully open.

Radiator is leaking at the connections

Ensure that the valve tails and the blanking plug are properly tightened and that PTFE tape was used correctly during installation.

Setup, Compatibility & Care

Installation should be carried out by a competent person or professional plumber to ensure the unit is correctly integrated into your existing central heating system. The radiator comes with all required wall fixings and brackets to facilitate a secure mount.

Compatibility: This model is compatible with all standard domestic central heating systems. Before installation, confirm that your current pipe spacing matches the wall-to-centre distance of 50 mm.

Care and Maintenance:

  • Regularly bleed the radiator using the supplied bleed valve to ensure optimal water circulation and prevent air pockets.
  • Wipe the surface occasionally with a soft, damp cloth to keep the grey finish looking new.
  • Avoid using abrasive cleaners or harsh chemicals, as these may damage the powder-coated surface.
