Скачать или смотреть How to Bleed Your Radiators |

Bleeding a heat pump radiator is similar to bleeding a traditional radiator. It involves releasing trapped air that can prevent the radiator from heating up properly. Here’s how you can bleed a radiator connected to a heat pump:

Tools Required:

• A radiator bleed key (or a flathead screwdriver, depending on the type of valve)
• A cloth or towel
• A container to catch any water

Step-by-Step Process:

1. Turn Off the Heat Pump:
Before bleeding the radiator, turn off the heat pump system. This prevents any water from circulating while you are releasing the air, ensuring the process is safe and effective.
2. Locate the Bleed Valve:
Find the bleed valve at the top of the radiator. It’s usually a small valve that can be opened with a radiator key, a screwdriver, or in some cases, a special tool provided by the manufacturer.
3. Position a Container and Cloth:
Place a container or a bowl under the bleed valve to catch any water that may come out. Use a cloth to protect your hands and the area around the radiator from any drips.
4. Open the Bleed Valve:
Using the radiator bleed key or screwdriver, slowly turn the valve counterclockwise. You’ll hear a hissing sound as the trapped air escapes.
5. Wait for Water to Flow:
Keep the valve open until the hissing stops, and a steady stream of water starts to flow out. Once you see water, it means all the air has been released.
6. Close the Valve:
Turn the valve clockwise to close it tightly, but don’t overtighten. Just ensure it’s closed enough to prevent any water from leaking.
7. Check System Pressure (if applicable):
If your heat pump system has a pressure gauge, check it after bleeding the radiator. Releasing air can sometimes lower the pressure. If necessary, you might need to top up the system with water to bring it back to the correct pressure.
8. Turn On the Heat Pump:
Turn the heat pump system back on and check that the radiator is heating properly. The trapped air should now be gone, allowing the radiator to heat up efficiently.

Final Checks:

• Inspect the radiator and valve for leaks.
• Repeat the process for other radiators in the system if needed. If multiple radiators are cold, it might be necessary to bleed them all.

Regularly bleeding radiators ensures efficient heating and can prevent issues with your heat pump system.
