Radiators

designed to heat the air in the room using convection to transfer heat from the radiators to the surrounding air. They do this by drawing cool air in at the bottom, warming the air as it passes over the radiator fins, and discharging the heated air at the top. This sets up convective loops of air movement within a room. If the register is blocked either from above or below, this air movement is prevented, and the heater will not work. Baseboard heating systems are sometimes fitted with moveable covers to allow the resident to fine-tune heating by room, much like air registers in a central air system



Air can become trapped in your central heating system. This is known as an air lock. Common causes of air in the central heating system are incorrect refilling or lack of inhibitor in system

Radiators with airlocks or air in them

Radiator cold at the top because of air
sludge in radiator cause cold spots


Are your radiators cold in the middle or not getting hot this could be the cause by sludge or air in the heating system

What is sludge?


Sludge is a cumulative name for rust and debris found in your central heating system water. The rust comes from you radiators ageing in the water just like a nail would rust in water. The process can be stopped or dramatically slowed down by adding inhibitor which is a chemical you can buy in any DIY or plumbing shop. protect the system against rusting again after it's been cleaned. Always have inhibitor in your system. for more information please contact SM plumbing services



 

A thermostatic radiator valve (TRV) is a self-regulating  valve fitted to hot water heating system radiators, to control the temperature of a room by changing the flow of hot water to the radiator, if the TRV is not working this can also cause the radiator to be cold and can also become noisy the TRV may need replacing
