A Step-by-Step Guide to Bleeding your Radiators

Your boiler will thank you for it.

Keeping your home toasty throughout winter relies on two key players: your boiler and your radiators. But even the most efficient boiler can struggle if air gets trapped in your radiators. That’s why it’s so important to regularly bleed your radiators.

What does it mean to bleed your radiators?

Bleeding simply means releasing any trapped air bubbles that accumulate within your radiators over time. Air pockets prevent hot water from circulating properly, creating cold spots and forcing your boiler to work harder to maintain warmth.

Why bleed your radiators?

Bleeding your radiators is important for several reasons.

By removing air blockages, hot water flows freely throughout the radiator, allowing your boiler to function more efficiently. This translates to lower energy bills and a potentially longer lifespan for your boiler. Trapped air can also cause uneven heating, leaving some sections of the radiator cooler than others. Bleeding ensures all areas heat up uniformly, providing comfortable warmth throughout your home.

A boiler constantly battling trapped air is under unnecessary stress. Regular bleeding helps your boiler work smoothly and efficiently, potentially extending its lifespan. A well-bled system heats up faster and maintains consistent temperatures, keeping your home cozy and comfortable.

How to bleed your radiators

1. You’ll need a radiator key (available at most hardware stores) and a container to catch any dripping water.
2. Turn off your central heating and wait for your radiators to cool down completely.
3. Locate the bleed valve. This is usually a small valve on the top corner of the radiator, sometimes with a square notch for the radiator key.
4. Place the container under the valve and open the valve slightly by turning the key counter-clockwise. You’ll hear a hissing sound as air escapes.
5. Wait for the hissing to stop. Once only water comes out, close the valve firmly by turning the key clockwise.
6. Repeat for each radiator. Work your way through your home, bleeding each radiator in the system.
7. Check your boiler’s pressure gauge (consult your boiler manual if unsure) and adjust if necessary.

Beware of scalding: Use caution as hot water may come out during bleeding.

By following these simple steps and incorporating regular bleeding into your home maintenance, you can ensure your radiators function optimally, keeping your home warm and cozy while extending the life of your boiler.
