Why Are My Radiators Not Heating Up Properly?

Common Reasons Radiators Aren’t Heating Properly

There are several common causes:

• Air trapped in the system
• Sludge build-up in radiators
• Faulty or stuck valves
• Circulation issues
• Balancing problems

These are all issues I regularly come across when carrying out heating repairs in East Grinstead and surrounding areas.

How To Fix It

1. Bleed Your Radiators
Removes trapped air and improves heat output.

2. Check the Valves
Ensure both sides of the radiator are open and working.

3. Check Boiler Pressure
Low pressure can affect circulation.

When To Call a Heating Engineer

If the problem continues, it may require:

• System flush
• Valve replacement
• Pump or zone valve repair
