I moved into a house 5 days ago, and the radiators needed bleeding. I did this and when I turned the boiler on to check the system the pressure gauge would not budge from zero, it needs to be on a reading of about 1.0 to 1.5.
All I did was bleed the bl**dy radiators. Please Help!
The pressure was there before.

You should have a filling loop or water switch on the unit that your turn on like a tap to fill the system.

ken you need to open the filling loop on the boiler i.e a flexi pipe with 2 valves when open you will here water entering the central heating system as this goes in the pressure gauge will go up the filling loop is probably located under the boiler note in future you should add pressure before bleeding rads as you can damage expansion vessle in the boiler so top boiler up then bleed 1 rad and continue this routine till all rads bled of air if pressure is to high after last rad just open a rad air vent and water will come out dropping pressure on gauge hope that helps
