It often happens that despite the increase in temperature on the thermostat, the house is still cold. There can be many reasons, but the most common is an aerated radiator. This problem should not be underestimated. Find out how to vent your radiator so you don’t have to worry about the temperature and your bills later.
Outside temperatures are getting lower every day and snow has already fallen in many parts of the country. It can be said that the heating season has started for good in Slovakia. Although many of us have already turned on the radiators, some are still cold. Why are radiators not working as they should? They probably need to be vented.
Why is the radiator cold at the bottom? Check that the radiator is vented
Experts have been appealing to Slovaks for several weeks to prepare their homes for the heating season. Before raising the temperature, it was important to check that all radiators in the home were working properly and that they did not need to be vented. Air often collects in the central heating system, so the radiators cannot fully transfer heat. This process occurs for several reasons. Among them are, for example:
- incorrect filling of the system,
- insufficient ventilation before the heating season,
- low-quality execution of individual components of the system (plastic surfaces can cause leaks in the entire system),
- type of installation (open installations are more likely to vent).
If the radiator does not work properly again during the heating season, it is worth venting it again. Only after the accumulated gases are removed, the water fills the pipes over the entire surface of the radiator, which improves the efficiency of the system.
How to vent the radiator in the bathroom? Step by step instructions
Bleeding the radiator is not difficult. You don’t need to call an expert because you can easily do it yourself. Before you start, however, protect the area around the radiator from water that will escape from the pipes. Place a large bowl or thick cloths so that moisture does not damage the floor.
- To begin, turn off the thermostatic valve and check that the control is set to 0 or points to the star symbol.
- Then, using a screwdriver or a special key, unscrew the valve. First, carefully loosen the screw and then slowly unscrew it above the bowl.
- At this point, you will hear a characteristic hissing sound water starts to flow from the pipe. This is a sign that the radiator has been properly bled.
- After the air has escaped, dry the breather with a cloth and screw it well.
- Finally, unscrew the thermostat and check that the heat spreads over the entire surface of the radiator.
