Customer Question

Viessmann Vitodens 100 (with header tank) fires up and then cuts out at 50 -56 degrees. One rad on it's own and it will go higher. Cut out temperature seems to rise through the day, but will only really heat 3-4 of 20 rads properly. First rad getting a lot of air in it. Help please
