How do I increase water pressure from red to green on greenstar 28i?
Desperate as it is freezing. Can't put on central heating cos guage shows it in the red on 0. I know I have to increase this via filling loop but don't know how to do it. Please help!
remove the white slide out plastic panel on the underside of the boiler, there should be a plastic key on it. stick the key in the bayonet hole and give a quarter turn to lock it, then let the water in by turning the small grey plastic tap beside the key. take the pressure up to around 1.5 then re-set the boiler and that should be it.
see page 32 of the manual for a diagram if this is difficult to understand.
Don't know the 28i, but in principle, If there's a red light and it goes out then you've probably won! the filling loop is a flexi-pipe which may or may not be already fitted between two stoptaps somewhere either below the unit or elsewhere in the pipework. If it's 'around' but not fitted, there should be two adjacent taps with open ends. Fit it and then open both taps and watch the gauge. If you overfill it then reduce the pressure by bleeding one of the radiators.
