Grant Vortex Oil Boiler fault, CH stops when HW is running?

Hi all

We have Grant boiler
It never bothered us before but i’m curious to know whether this is a fault or normal for Grant boiler central heating to stop when the hot tab is running?
Also when the hot tab is off then it takes CH 5-10 mins to come back on

Any suggestions much appreciated

Thanks
