My central Heating does not work, but my hot water does. What is the problem. I have put new batteries in the thermostat wireless box, but the central heating does not come on.

is the control on your boiler set to hot water and central heating or just to hot water
if yur thermostate works for the water it shold work for heating it could be your heat exchange unit with in the boiler it self is blocked it does happen so you will have to call an enginner out
