Hi, I have just bought a conversion flat with a dated Valiant Combi wall mounted boiler model vcw sine 18 t3wf I turned the heating on and noticed the rads were only hot at the bottom and gargerling noises were coming through them I turned the heating on one evening for 10 mins then bled the rads - after 10 mins the rads went cold and there was no running hot water The boiler pressure after checking was at 0, I pumped more water through the loop which got the pressure back upto 1 but I still have no heating or hot water - Normally when I turn the hot water or heating on the pilot ignites but since the loss of pressure the pilot (is on) does not ignite and heat up Does anyone have any ideas what I can do?
*help*! Kay
