Bleeding Your Radiator from the Consumer's Perspective
When Should You Bleed Your Radiator?
- When the surface of a radiator is not uniformly warm.
- When you hear a gurgling or flowing noise in the radiator.
- After refilling the system with water.
Follow These Instructions:
If you need to bleed multiple radiators, start from the lowest floor and work your way up.
- Turn on all radiators in the house and let your central heating run for at least 10 minutes. This allows air to collect at the bleeding valves.
- Set the thermostat to the lowest setting so the boiler stops heating.
- Turn off the central heating. Wait until the radiators have cooled down.
- Start bleeding:
- Have a bleeding key, an absorbent cloth, and a collection container ready. The water in the central heating system may be dark brown to black and could cause stains.
- Locate the bleeding valve. This is always found at the top of the radiator, on the opposite side from the thermostat head.
- Slowly turn the bleeding valve counter-clockwise until you hear a hissing sound. After a short while, water will also come out. Close the bleeding valve again as soon as the water stream becomes even. If the water continues to drip, it is recommended to replace the bleeding valve.
Note: For ECO radiators with 2 openings, the radiator is only fully bled when water emerges from both openings.
Important: If the ECO radiator has 2 openings, the radiator is only bled when water comes out of both openings.

- Turn the central heating back on.
Ensure Sufficient Pressure and Avoid Leaks
After bleeding the radiators, the system pressure may be too low. You can increase the pressure by filling the system to a working pressure of 1.5 to 2 bar (refer to your boiler's specifications). The shut-off valve is usually located near the boiler. Open the shut-off valve and observe the pressure gauge on the boiler. Close the shut-off valve once the boiler shows the ideal pressure.
What is an ECO Radiator?
The ECO radiator concept is unique. Warm water flows directly into the front panel, giving it a higher temperature. This creates more radiant heat, enhancing your comfort. Due to the higher radiant temperature on the front, less radiant heat is lost through the wall on the back of the radiator. This means increased comfort and efficiency, a lower energy bill, and reduced CO2 emissions for you.
How to Identify an ECO Radiator?

An ECO radiator can be identified by the type of bleeder and a marking on the side.
