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.
