Have been reading entries where people have bled radiators and lost pressure in their central heating system - I think I've done this, and need help! Can anyone tell me where I might find this much-referred to 'filling valve' or 'filling loop'? My boiler is made by Ariston, no idea what model, it's recent, but very basic (has a clockwork-type timer and just a few buttons!).
Thank you in anticipation!
