How do I bleed the radiators, step by step?
First of all, don't panic. Anyone can do it and it is a fairly simple process in which you basically have to be careful with 3 little things:
- he boiler pressure
- The water temperature
- The bleed valve
Now, let's move onto the steps:
- Check the system.
Turn on the heating and run your hand over the top of the radiator. Then do it from the bottom. If they are at different temperatures (the bottom hot and the top cold), you need to bleed it. The air rises to the top and therefore it stays cold (not being in contact with hot water, but with air).
- Wait by the first radiator.
Go to the radiator closest to the boiler. You need to know the route the water takes and bleed the radiators starting with the one closest to the boiler, ending with the one furthest away. In this way, we ensure they're all bled properly.
- Bleed the radiator.
You need a container (a large glass will do), and a screwdriver. You can also use a cloth in case some water spills.
Next, find the valve at the top of the radiator and follow these steps:
- Place a container under the valve. Hold a bowl or glass and place it under the valve. If you look closely, there is a small spout where the air will come out followed by the water, so make sure the container is right below it. This will prevent the floor from getting wet when the water starts to come out through the valve.
- Open the valve with a screwdriver. You can also use a coin to open the valve tap. The valve opens and air begins to “hiss” until water begins to come out. The jet will not be uniform so you must wait until it is fluid to close the valve.
- Repeat the operation on all radiators. Remember to follow the flow of the water, radiator by radiator.
- Reset the boiler pressure.
When you have bled all the radiators, you should check the pressure on the boiler. You should follow the manufacturer's recommendations, but boilers are usually set between 1 and 1.5 bars. The most common setting is to leave it at 1.5 bars.
- Enjoy the comfort of the optimal temperature.
Now, the only thing left to do is to check that the system works efficiently and observe the improvement in your home's heating
