Linking multiple domestic boilers

    Hi All,
    I have been trawling the web looking for answers regarding linked heating systems.
    I am doing a big renovation on my home place and need some advice,

    The house has currently has a back boiler stove and a firebird oil boiler which are simply tee'd into each other and a mix match of different types of pipes, pumps, valves etc etc etc.
    Well I should say it had, It now has nothing what so ever. My plan is to upgrade the Solid fuel stove to become the primary heating (this is what I have in my current house and am very pleased with). But what I do miss is an automatic source of heat (When we are out in the evening or when the stove has gone out in the early morning) The firebird is my answer to that.

    In addition to that I would like to fit a solid fuel range as it is something we would like and it would be multi purpose.
    All are at ground level and the stove and oil boiler are on opposite ends of the building. The plumbing from the oil boiler will pass the range on route to the Hot water cylinder upstairs and the solid fuel stove would be direct to the cylinder.
    So my thoughts at the moment are to tee in the range to the oil boiler pipes with non return valves where required. That would reduce my problem to two feeds which I guess would work with a dual core cylinder but then I cannot have the rads working off all systems.
    I was thinking of perhaps a Spirozone unit at the tank to sort things out or is it safe to build a manifold with non return valves ? The system will be vented.

    On the other side of things I love the idea of a buffer tank owing to the fact that I could add a solar panel in future or if Oil prices went crazy I could change to an out door type solid fuel burner. They are quite costly though, If I had a buffer tank do I eliminate the hot water cylinder.

    It needs to be a basic system, I don't want electronic valves and most likely all the radiators will remain on when ever the heating is on as its an old building and keeping it dry is paramount.

    I have plumbed a few previous restorations, all vented basic systems but this one I will hopefully have to live with for a very long time and it is as such a blank canvas, as are my pockets by the way, so what ever I spend has to be carefully thought about.

    Sorry for the long winded post but there's no point in giving anyone half the details.
    So recommendations please !
