The boiler is an Ideal combi boiler. One radiator had to be bled because it was cold now the pressure is sitting at zero. Looked at boiler underneath. There is a blue and yellow knob, the stop cock and one at each end that may use a key, I think. which one do I turn to big the pressure up to 1. Or should I phone an engineer. Thanks
dont mess wit the coloured taps. they isolate the boiler from gas and water. a seporate filling link should be present usually below the boiler. the system should be topped up when cold and filled to 1 bar on dial.

there should be a filling loop from the blue tap pipework to the bigger 22mm central heating pipe
