We have a pottertton combi 28 he boiler. Pressure is set at 1.5 bar.
When I turn the heating on this drops to around 1/ below 1. Once the heating is on and running it’s back around 1.5/2, and when it’s completely off and cooled it’s back at 1.5 like it was before it was turned on Is this normal?
We’ve noticed it takes a while for the boiler to kick in/ ignite once the heating has been turned also. Can take around 20 seconds.
We’ve not long had it serviced
