A cold radiator is a big problem, especially during cold season. An emergency Plumber (with experience in radiator and heating problems) is able to test and repair the defective radiator. A cold radiator may have several causes, not directly linked with the actual radiator, so it is important to inspect and detect all the issues with the heating installation.

A cold radiator can be repaired by inspecting the heating installation, detecting leaks, other plumbing/heating-specific procedures (pipes, boiler, connectors, valves).

You may have only one cold radiator or several cold radiators - or partial cold radiators.
Depending on the problem, a professional plumber will be able to detect the defective part of the heating/radiator installation and perform the repairs - including changing parts if necessary - in order to restore your comfort and avoid future radiator problems.
If you see wet spots under the radiators, see reduced pressure in the heating installation or if you have one or several cold - or partially cold radiators, give us a call as soon as possible in order to avoid a future emergency.

DIY: How to detect if you have a cold radiator problem
With the heating on, inspect each radiator in all the 4 corners. If the entire radiator is cold, verify if the valve of the radiator is open. If the radiator is only partially cold, contact a 112 plumber using the following form.
Next, verify if you have any visible leaks under the radiator. You can use some paper to see if there is a wet spot - but please remember that even if you do not see drops of water, the radiator may still have a leak.
