How to Fill a Towel Radiator?

Published in Plumbing 2 mins read

To fill a towel radiator, you'll need to manually add water (or a water/inhibitor mixture) into the radiator through the top inlet, ensuring you leave an air gap. Here's a step-by-step guide:

  1. Position the Radiator: Ensure the towel radiator is oriented correctly (right-side up).
  2. Access the Top Inlet: Locate the top inlet point on the radiator. This is where you'll introduce the water.
  3. Fill with Water (or Water/Inhibitor Mixture):
    • Carefully pour water into the top inlet. Ideally, use pure water, but you can mix it with an anti-freeze or corrosion inhibitor solution (follow the manufacturer's instructions for the correct ratio). The inhibitor helps prevent rust and corrosion inside the radiator.
  4. Leave an Air Gap: Fill the radiator almost to the top, leaving a 2-3 cm (approximately 1 inch) gap at the top. This air gap is essential for the water to expand when heated, preventing over-pressurization and potential damage.
  5. Check for Leaks: Once filled, thoroughly inspect all connections and the body of the radiator for any signs of leaks. Tighten any loose connections as needed.

Important Considerations:

  • Inhibitor Use: Using a corrosion inhibitor is highly recommended to prolong the life of your towel radiator and maintain its efficiency. Consult a professional if you're unsure about the correct type or concentration to use.
  • Safety: Always take care when working with water and plumbing. Turn off the power supply if it is an electric radiator and make sure any water spillage is cleaned up immediately.
