My boiler is reading empty how do I fill it

Mwil, March 2009

You didn't say which model Worcester boiler you have,some models have their own plastic filling key which is inserted in a hole under the boiler and along side this hole is a plastic knob which is turned anticlockwise to let water in, you must insert this key first, fill to 1 bar then clockwise for off, pull out the key. Otherwise look for the filling loop.

I presume that you mean the pressure gauge on the boiler isn't showing any pressure?
If so you need to use the filling loop to fill the system to the pressure required from the mains. Its lower then the mains so will do this. First attach the filling loop (a flexible braided silver coloured pipe) to both ends to connect the mains to the boiler system. This may either be near the boiler or remote (airing cupboard or even roofspace for example). Turn on the valves and watch the needle on the gauge rise. When it reaches the green area or other designated mark turn the valves off. Disconnect the filling loop to comply with water regulations. You may have to reset the boiler. Note that if boiler not been on for a while and cold don't pressurise the system as it expands as it heats up gaining more pressure. Hope that helps you.
