How to Bleed a Radiator: A Step-by-Step Tutorial & Buying Guide
Radiators are a vital part of any home’s heating system, especially in colder months. If your radiator isn’t heating properly — cold at the top and warm at the bottom — chances are it needs bleeding. Air trapped inside the radiator can prevent hot water from circulating properly. The good news? Bleeding a radiator is a simple DIY task that can restore efficiency and comfort in minutes. In this tutorial, we’ll walk you through how to bleed a radiator safely and effectively, and provide a buying guide for radiator products available at Radiator Village.

Part 1: Why You Need to Bleed a Radiator
When air gets into your central heating system, it can rise and collect in your radiators, creating cold spots and reducing heating performance. Common signs you need to bleed your radiator include:
- The top of the radiator is cold while the bottom is hot
- Gurgling or bubbling noises
- Rooms taking longer to heat
- Your boiler or central heating system working harder than usual
Bleeding releases the trapped air, allowing hot water to circulate evenly through the radiator.
Part 2: Tools You’ll Need
Bleeding a radiator requires just a few basic tools:
- Radiator key (you can buy one from most hardware stores or Radiator Village)
- Old towel or cloth
- Container or bowl (to catch any water)
- Gloves (optional, but recommended)

Part 3: Step-by-Step Guide on How to Bleed a Radiator
- Step 1: Turn Off Your Central Heating
Before you begin, turn off your heating system and allow the radiators to cool completely. Bleeding a radiator while it’s hot can be dangerous due to high pressure and hot water.
- Step 2: Locate the Bleed Valve
Find the bleed valve — a small square or slotted screw at the top of the radiator, usually on one end. This is where air is released.
- Step 3: Insert the Radiator Key
Place a towel under the valve to catch any drips. Insert the radiator key into the valve and slowly turn it counterclockwise (anti-clockwise). You’ll hear a hissing sound — that’s the trapped air escaping.
- Step 4: Let the Air Escape
Keep the valve open until the hissing stops and a steady stream of water begins to flow out. That means all the air is gone and it’s time to close the valve.
- Step 5: Close the Valve
Turn the radiator key clockwise to tightly close the valve. Be sure not to overtighten, as this can damage the valve.
- Step 6: Check the Boiler Pressure
Bleeding radiators can lower your boiler’s pressure. Check the pressure gauge (usually on the front of your boiler). If it’s too low (typically under 1 bar), you may need to top up the boiler with water according to the manufacturer’s instructions.
- Step 7: Turn the Heating Back On
Switch your heating back on and allow the radiators to heat up. Check that the previously cold spots are now warm and functioning properly.
Tips for Radiator Maintenance
- Bleed radiators at least once a year, ideally before winter.
- Always start with the radiator closest to the boiler and work your way out.
- If you need to bleed radiators often, there may be a deeper issue — consult a professional.
- After bleeding, keep an eye on water pressure and refill the boiler if necessary.
