Do you have any sort of loading valve on the stove such as a Laddomat or Esme? Using a stove with backboiler that does not make use of a laoding valve can result in very poor stove performance, there are several threads on this subject if you want to read more about it. The usual results due to lack of loading valve appear to be radiators never getting properly warm, excessive tar and soot production and the house always feeling cold!  Two other factors that can contribute to poor stove heating are gunked up pipes, try powerflushing the system (this will apply regardless of whether you reply on the stove, oil boiler or ASHP), and not having the lockshield valves on the radiators set properly (again there is a recent article about that).  Obviously this won't help with your flick a switch and have the heating come on, but might improve the stove and radiator performance significantly.  Are there any pums/valves on the stove circuit to direct the hot water to the DHW tank or central heating?

What make/model of stove is it you have? Some you can take the boiler out of, others you can't is my understanding. Have you thought about combining the stove and oil boiler using either a thermal store or neutraliser etc. That way you could also get a away with a smaller oil burner (less expensive) which would cycle less, but rely on using the stove if the weather came along with a really cold spell.
