a. Bleed the radiator to remove air
Bleeding the radiator is the simplest and most effective way to restore proper heat circulation. Here's how to proceed:
I. Bleeding Steps
Turn off your boiler to avoid burns or splashes.
Wait for the system to cool down.
Get a bleed key or a small screwdriver.
Place a container under the valve (usually at the top of the radiator).
Open the valve slowly: you should hear a hissing sound of air escaping.
As soon as water starts to flow steadily, close the valve.
Then check the boiler pressure. If it is too low (below 1 bar), readjust it to between 1 and 1.5 bar.
b. Cleaning a dirty radiator
If bleeding the radiator isn't enough and the bottom remains cold, sludge has likely accumulated. You'll then need to consider descaling the radiator, either with a cleaning kit or by a professional for a complete system cleaning.
3. Preventing future temperature imbalances
To prevent the problem from recurring:
– Bleed your radiators at least once a year, ideally before the heating season.
– Regularly monitor your boiler pressure.
– Install a sludge separator or a magnetic filter to limit the accumulation of impurities in the system.
By following these simple steps, you can extend the lifespan of your heating equipment while optimizing your thermal comfort.
A radiator that heats evenly means more efficient heating, controlled energy consumption, and a more comfortable home in winter. Take a few minutes to check your heating system and improve its performance without any extra cost.
