Central Heating won't heat radiaters but do have hot tap water?

I have an Optima 700 boiler/central heating system. When I turn up the room thermostat it clicks but the boiler doesn't heat the radiaters. Pressure is above 1 bar. I do get hot tap water just no heat to the radiaters. Any suggestions?
