thanx for your replies,didn\\\'t think it would happen so fast.Agile thanx 4 the great step by step descriptive info.I\\\'ve done as you said and i do now have water and heating but the heating is warmer in some places (closer to the Boiler) and the 3 furtherest do not warm at all.I repeatedly flushed the system again (cos water was orange cos of rust) until water ran clear.As far as i'm aware there is no zone valve.The pump is at 10 past eight,do I need to adjust it ,if so which way and how much.Bengasman how is power flush done?and how do you intr inhibitor/descaler into system if no tank in loft?advice much appreciated.Also advice on keeping bill down.Is it cheaper to run heating on low all the time or on high on timer say twice a day and does switching spare radiators off make any difference?How can u tell which valve is for what on the radiator,and which way to turn and how much.how was i supposed to isolate the valves on the boiler?yes i need the idiots guide to.As i said I\\\'m new to all this.thanx again
