fill it back up from the filling loop which in your case could be a plastic plug in fixed to the back of the bottom panel

Yes thanks have have now done that, just moved in to house, previous owners had blocked in filler tap! doh!

Can't find the unit reset switch either?, I have switched the mains electricity supply off and on but the heating has not fired up, hot water working ok

Thanks again

Similar to the above but ch and water ok. Radiators much hotter than usual. Pressure has dropped to very low. How do I top up pressure to red line? Thanks for any help
