What Makes Radiators Bang So Loudly

The video explains why radiators make loud noises, particularly banging sounds. It describes the mechanics of steam radiators, where steam expands and moves through pipes, and how air vents can cause whistling noises. Banging sounds occur when condensed water is trapped and thrown against the radiator walls, often due to improper radiator positioning or partially open intake valves. The video advises checking for physical obstructions and suggests calling a plumber if the noise persists.

What is the primary function of the central boiler in a steam radiator system?

• To condense steam back into water

• To boil water and generate steam

• To cool down the steam

• To filter minerals from the water

What might cause a whistling sound in a radiator?

• Limescale buildup in the air vent

• A partially open intake valve

• A tilted radiator

• Condensed water hitting the walls

Why does banging occur when steam condenses quickly in a radiator?

• The air vent is clogged

• The radiator is tilted

• A vacuum is created, pulling water into metal

• The steam expands rapidly

What can cause a radiator to make hammer-like sounds?

• The radiator is perfectly level

• The intake valve is fully open

• Stuck liquid water cooling steam quickly

• The boiler is malfunctioning

What should you do if your radiator is making loud noises?

• Contact the Ghostbusters

• Call a plumber

• Ignore it and hope it stops

• Turn off the central boiler
