If the radiator requires bleeding it will be hot at the bottom and cold at the top.
If the radiators that are struggling to get hot are the furthest ones away then by restricting the flow through the nearer radiators (balancing the system) It will enable more flow through the further radiators.
A quick way of diagnosing this is to turn off the radiators that are very hot and if the others then heat up then the problem is circulation.
Poor circulation can be caused by an unbalanced system, insufficient pump pressure, inadequate pipe sizing and sludged up or partially blocked pipe-work
Hope this helps

As you stated it is probably one or all of the above problems, you need to grt it checked out as wood burners do not self regulate and you could damage the boiler unit if it overheats.
