In the event of a central heating failure, you can call the installer responsible for the maintenance and the failure of your individual central heating system or boiler. You will have information on the installer, and you will usually find these details on a sticker on the boiler.
If the hot water supply is included in the rental agreement (this is not automatically the case), you can contact this installer directly.
If you are connected to a joint central heating system (which will be the case if your heating costs are charged via Grouwels Vastgoed), you can contact the building manager. In the case of district heating, you should contact your supplier.
If there is an urgent leak, you can contact this installer.
