No Heating

Help I have no Heating. Recently i have had to bleed the bathroom radiator nearly every day, and it is taking longer and longer to bleed, whilst bleeding it the water tank in the airing cupboard make a lot of gurgling sound. Now today there is no heat at all, I have tried to bleed the rads and nothing is coming out. where has all the water gone? there does not seem to be any leaks in the house. . Also the red pump in the airing cupboard is to hot to touch.

Check in the tank in the airing cupboard, I fully expect there to be no water in it. Move the ball valve arm up and down and it should spring into life. This should fil the system. Once all the air is bled from system you should be fine
