Please advise.

There has been 4 extra radiators added to existing heating system. I have solid fuel and dual hwc. It seemed as if my back boiler in range was under sized for 10 rads but have issue also when i use oil heating. I have to turn off 2 radiators untill all other rads roasting then give 2 rads a few half turns will be fine and work. But if all rads on together on solid fuel it can take 6 hours before good heat. On oil i have to set pump 3 and temp 75. Also my rads heat up on top several times into early hours. Any advice appreciated 3 plumbers in waste a diff issue each time never able to actually fix issue.

So basically if i turn off 2 rads when lighting fire or using oil heating and rads get roasting then turn on the 2 rads it stays working but if i have all rads on to start nothing works right ?? Have extra 4 rads restricted. Is my hwc too small? Or my small tank attic its open vented system f&e
