HV G-10 B&G 102210 HP 106 installation

My heating boiler has 3 zones with separate pump and thermostat. The zoned pipes get hot, and then cool off. The system has been bled. The hot air doesn't last long. What's the fix?

    Need more information and pictures. are the circulators running when the thermostat calls? Is the house reaching the thermostat set point?
