If a radiator does not heat, first check whether the problem is limited to one radiator, the whole flat or other flats too. This information helps us organise the right help faster.
Check the setting and access to the radiator
Check that the radiator valve is open. Do not cover the radiator and thermostatic head with furniture or heavy curtains. If the valve sticks, do not force it.
Listen for noises and uneven heating
Gurgling or a cold top part of the radiator may indicate air. Bleed the radiator according to the instructions for your heating system. If you are not familiar with the procedure, contact the caretaker or a qualified contractor. Do not let large amounts of water out of radiators.
If the radiator stays cold
The cause must be checked by a qualified contractor. Do not dismantle valves yourself or change the settings of the shared system. If several flats have similar problems, inform the caretaker or the building manager.
When reporting, please state
- The building address, entrance and flat number.
- Which radiators are not heating and since when.
- Whether your neighbours have a similar problem.
- What you have already checked and a contact for an inspection.
Report the problem through the Practic portal (opens in a new window). In buildings with a single-pipe system, do not follow instructions meant for two-pipe systems; for a safe procedure, contact the caretaker or a contractor who knows your building's system.
