I have just removed three radiators from my bedrooms upstairs and I have just noticed that I now have zero pressure in my combi boiler. I now only have cold running water but no hot in shower (mixer) or through any taps. Can anyone help?
My combi boiler is a Greenstar 25si/30si - don't understand short para in manual.
water pressure can be toped up via a filling loop which for a greenstar should look like a flexi silver pipe, which is often found either ontop of the boiler or inside the boxing underneith it, you must connect the filling loop to the two blank pipes with service valves on stated in the manufacturers instructions. once attached open the service valve and pressurise to 1.5 - 2 bar ( using the pressure gauge on the right hand side of the boiler control pannel. once filled shut both service valve and remove filling loop, job done. good luck!
