Is it normal for this boiler to do the following
CH thermostat requests heat - then sequence of events
Boiler running time: 8mins
Rest: 30sec
Boiler running time: 5mins
Rest: 40sec
Boiler running time: 3mins
Rest: 40sec - 1min
Then
Boiler running time: 2min
Rest : 40sec - 1min
Which then cycles at 2min running, 1 min rest until up to temperature.
It can take up to if not over 1 hour to raise the temperature by 1.5c
Boiler setting 6, pump speed 3, 20 rads, 3 storey house.
Any ideas, is this normal for this boiler?
