How does a steam radiator air valve work?

As the radiator fills with steam it pushes the air out through the open vent. This release of air pulls steam into the vent. The Radiator air valve is heat-sensitive, and ultimately the valve closes trapping the steam in the radiator to heat the radiator.

How much does it cost to bleed radiators?

Baird warns that letting out too much water is likely to introduce fresh water into the system, which can make the situation worse as fresh water contains a lot of air. He adds: “Some people also think if a radiator is cold on the bottom but hot at the top then it needs to be bled.

Why is radiator hot at top and cold at bottom?

If you have a radiator that is getting hot at the top but cold at the bottom, it isn’t a problem with air being trapped in that rad.
