Uneven heating of a radiator is a common problem in many houses and apartments, especially at the beginning of the heating season. However, before you decide that you are facing an expensive repair, check the most common causes and simple methods that you can use yourself.
This is one of the most typical symptoms of problems with water circulation in the radiator. When his the upper part is hot and the lower part is completely coldit means that the water is not flowing properly. Most often, two things are to blame: air in the radiator or a contaminated heating system. Under normal conditions, hot water should distribute the temperature evenly over the entire surface of the radiator. However, when there is air or sediment inside, the flow is disturbed and the radiator does not heat as it should.

In most cases this is enough bleeding the radiatorfor the problem to disappear. The air that has entered the installation blocks water circulation and causes the lower part of the radiator to remain cold. This is how you do it step by step:
- Close the radiator valve and wait until it cools down completely.
- Place a dish or towel under the vent valve.
- Gently unscrew the valve using a wrench or screwdriver.
- Wait until air begins to escape from the radiator and then a stream of water appears.
- When only water comes out of the valve, turn it off and turn on the radiator again.
After a few minutes you should notice a difference. The heat spreads over the entire surface of the radiator, not just the top.
If bleeding does not help, the cause may be dirty installation. Over the years, scale, rust and sludge accumulate in pipes and radiators, restricting water flow. This causes the radiator to only partially heat and consumes more energy. Here’s dohmic way to clean the radiator:
- Turn the water tap to maximum flow and leave the heater on for a few hours.
- Then restore the previous settings – this is often enough to improve water flow.
- If the problem persists, call a plumber who will professionally flush the system and remove the accumulated sediment.
