A plumber warns of a serious mistake when bleeding heating radiators: they will not heat well all winter

Winter is coming, and with it comes the coldest days of the year. As temperatures drop, it is essential to ensure that your heating system is working properly to keep your home warm and cozy.

If it is not in perfect condition, you could experience radiators that do not heat properlycold spaces and an unnecessary increase in energy consumption, which will affect both your comfort and your pocket, due to the increase in the electricity bill.

To avoid these problems, one of the essential steps is bleed the radiatorswhich allows the air accumulated in the circuit to be eliminated, favoring the efficient circulation of hot water and ensuring that the radiators are heated evenly.

If you do not perform this maintenance, it is likely that certain areas of the radiator will remain coldmaking it difficult for the heating to reach the ideal temperature. However, there is one mistake that many people make when purging, and that is that they do not adjust the system pressure after doing so.

This carelessness can cause the equipment to not function as it should throughout the winter, since heating needs adequate pressure to distribute heat evenly, it is for this reason that radiators must be bled correctly.

The correct process to bleed heating radiators

When you bleed radiators, you release trapped air, but you may also lose a small amount of water from the circuit. Loss of fluid can cause a drop in pressure in the heating system.

This way, if the pressure is too low, it may not work properly or even shut down for safety, which means that your radiators will not heat properly. To avoid this problem, do the following:

1. Before you start, make sure the heating is off and the radiators are cool to the touch. Next, you will need a petcock and a container to catch any water that may come out.
2. Starting with the nearest radiator, place the container under the radiator bleed valve and, using the wrench, slowly open it. You will hear a hiss, which indicates that the air is coming out.
3. When water starts to come out continuously, close the valve.
4. Follow the same procedure with all the heating radiators, moving from the closest to the furthest.
5. Once you have bled all the radiators, check the pressure on the gauge. The ideal is usually between 1 and 1.5 bars. If necessary, adjust using the fill cock or drain valve.

Remember that in addition to bleeding your radiators, it’s important to perform other checks to prepare your system to perform at its best all winter long. Make sure it is on heating mode and check for leaks in the system.

Avoid the common mistake of not checking the pressure after bleeding. With these simple steps, you will ensure a warm and cozy home, optimize heating performance and avoid surprises when you need to heat your home most.
