Wood-burner & boiler installation?

I am considering getting a wood burner installed but I am debating whether to get one with a back boiler to heat the bungalow. I have used an online calculator which suggests I need around 16kw output from the boiler. I have seen one which I like but don't want to rush ahead without investigating things further. I want to retain the oil central heating and have the wood burner supplement it when lit and heating the water.
Could someone advise what is involved when installing? Would it have to be connected up to all the radiators or how is it linked in? Would I require an additional tank or something similar in order to run two heating systems?
Any advice would be greatly appreciated.
Thanks
