2011 1.4 turbo issue 

Run car for 8 mins the top hose is hot  Cooling fan kicks in but bottom hose is cold but I have a fantastic heater I have changed thermostat no air lock and no oil in water took up the road for but still bottom hose and rad is cold even after 15 mins

What temperature is displayed on the instrument panel?

generally, the thermo-syphon effect within the cooling system means that the top will be hot and bottom will be cold and the coolant circulates (with the assistance of a water pump) within the engine and ancillary items such as the heater.
Therefore the bottom hose should be a lot cooler than the top one.
If you measure with an infrared temperature gun, the temperature should fluctuate (without any sharp dips or peaks) throughout the engine.
