Refill the Central Heating System

Is the heating not getting warm anymore, and is the boiler showing an error code? Then you may need to refill the central heating boiler. To check if this is the case, look at the pressure gauge in the meter cupboard. If it has dropped below 1 bar, the boiler needs to be refilled. You can easily do this yourself. Energiewacht explains how to do it in a video.
