There's a zone valve on the return pipe if that's not working properly would that cause cold water

hello i have a problem with the central heating system. When the hot water is switched on the boiler fires up but it does not fire up when the heating is put on. Also when the hot water is put on all the rads get hot. I thought it must be a port valve stuck but i cant find one.
