If your home is poorly heated, it may be time to bleed your radiators. Essential to the proper functioning of your installation, this bleed will allow you to improve the performance of your heating, and to make visible savings on your energy bill.Fioulmarket.fr explains how to bleed a radiator.
How to increase heating performance through purging?
To ensure the durability of your heating system and to heat without wasting energy, remember to bleed your radiators regularly, preferably before winter.
Why bleed a radiator
Over time, air can enter the heating ducts. Your radiators become noisy and lose efficiency. The bleed of the heater is intended to remove the air accumulated in the connector so that the water therein can again circulate freely. If it is recommended to purge the radiators of a house at least once a year, those located upstairs need to be emptied more frequently.
The bleed of the radiator should ideally take place before winter, before starting the heating. However, this maintenance can be performed at any time to increase the performance of its heating, especially if it heats little or not in its upper part.
Warning: if the connector does not heat well in its lower part, the bleed is often useless because it is a different problem. Then consult a specialized technician to diagnose the breakdown and repairs to consider.
How to drain its radiators safely?
Before purging your radiators, read the safety rules to proceed without taking unnecessary risks and burn yourself. Here are our tips for purging a heater safely :
- Make sure the boiler pump is not in working order. To do this, set the boiler to the summer position.
- Wait for the radiator to cool down, as water will drain during purging: if the heater is still hot, you may get scalded.
- Put on gloves to protect your hands if the radiator is not cold.
How to bleed a radiator?
Before emptying your radiators, take a small container and a bleed key. This tool is essential to loosen the trap (a small screw) to perform the bleed. Then it would help if you did the following:
- Insert the bleed wrench into the bleed screw usually located at the top of the radiator, on one of the sides;
- Place the container under the screw;
- Loosen the bleeder screw slowly until a hissing sound is heard: it is the air that starts to come out of the radiator;
- Listen to the whistling and let the water flow into the container if there is any;
- Tighten the bleed screw without forcing too much when the whistling stops and water starts to come out in regular net;
- Turn on the water supply system.
Once the bleed of your radiators is finished, you can add some water in the circuit to restore normal pressure.
