How To Bleed A Towel Radiator 

Bleeding a towel radiator is a simple DIY task that helps release trapped air from the system, improving its efficiency and heat output. Here's a step-by-step guide you can follow:

🔧 What You’ll Need:

• Radiator bleed key (or flathead screwdriver, depending on your radiator valve)

• Small bowl or cup

• Cloth or towel

🛠️ Step-by-Step: How to Bleed a Towel Radiator

1. Turn Off Heating

   • Ensure the central heating is off and the radiator is cool to avoid burning yourself or releasing hot water.

2. Locate the Bleed Valve

   • Usually found at the top corner of the towel radiator.

   • It looks like a small square-shaped bolt or slotted screw.

3. Place a Bowl or Cloth Under the Valve

   • This will catch any water that comes out during the process.

4. Insert the Bleed Key or Screwdriver

   • Turn it anti-clockwise (left) slowly — about a quarter to half turn.

   • You’ll hear a hissing sound as air escapes. That’s normal.

5. Wait Until Water Flows

   • Once water starts coming out in a steady stream (no air), close the valve by turning it clockwise (right) tightly — but don’t over-tighten.

6. Check the Boiler Pressure

   • After bleeding, your system pressure may drop.

   • Check the boiler pressure gauge (should usually be 1–1.5 bar when cold).

   • If it’s too low, top it up using the filling loop (consult your boiler manual).

7. Turn Heating Back On

   • Let the radiator heat up and check if it's warming evenly from top to bottom.

🔁 Repeat If Needed:

If other radiators are also cold at the top, repeat the process on each one.

⚠️ Tips & Warnings:

• Bleed radiators starting from the lowest one in the house and move upward.

• Do not fully remove the bleed valve — just loosen it.

• If you keep needing to bleed the radiator often, there might be a bigger issue like a leak or trapped sludge.
