If your central heating is not working, it could be down to a loss of water pressure. The water pressure indicator on the front of your boiler should read between one and two bars of atmospheric pressure. If it is below one, then your boiler pressure is too low.
To top up your system and increase the pressure, you will need to locate your filling loop. This is usually a silver/grey coloured, flexible hose with a small valve at each end, and you’ll find it either underneath your boiler or nearby:
Once the pressure is at the required level, switch the boiler back on and (if required) reset the boiler.
