Our Radiator Not Heating Up Solution for Parliament Hill

How to Diagnose Your Cold Radiator

1

Check Both Valves Are Open

Locate the valves at each end of the radiator. The thermostatic valve (TRV) should be set to a number, not 0. The lockshield valve (covered with a plastic cap) should be open - turn anticlockwise to open.

2

Feel Where It's Cold

Carefully feel the radiator when heating is on. Cold at top = air. Cold at bottom = sludge. Cold throughout = valve or system issue.

3

Check Other Radiators

If all radiators are cold, it's likely a boiler or pump issue. If just one or two, it's radiator-specific.

How to Prevent Cold Radiators

Bleed radiators annually before winter
Add inhibitor to your system (ask during annual boiler service)
Consider a power flush every 5-10 years
Don't let radiators go unused for long periods
Install a magnetic filter (MagnaClean) to catch sludge
Get annual boiler servicing - engineers check system health
