The Main Parts And What They Are For

The image below shows the main parts of a central heating radiator.

Central heating radiator overview

 

Lockshield valve – A lockshield valve controls the flow of water through a radiator. A lockshield valve can increase or decrease the flow of water that flows through a radiator. A lockshield valve is used to ‘balance a central heating system’.
 
Thermostatic Radiator Valve (TRV) – a TRV controls the flow of water through a radiator depending on the temperature of the surrounding room, i.e. a TRV is temperature sensitive.
 
The main difference between a lockshield valve and a TRV is that a TRV controls the flow of water to a radiator depending on the temperature of the surrounding room. A lockshield valve does not take any account of temperature.
 
Radiator bleed valve – the radiator bleed valve is used to remove air from a central heating radiator.
 
Indents – indents increase the surface area of a radiator, if you increase the surface area of a radiator the amount of heat given off increases.
