What a great response from everyone yesterday! I couldn't believe what good replies I got to my questions. Thank you!
I had my thoughts about biomass confirmed and I think we'll be changing the boiler for another oil one, but situating it outside. Hopefully I'll be able to fit this with the help of a friend I've just done some work for, so plumbing costs should be minimal for the straight boiler swap, just the extra pipe work to take it outside (which I can do as well).
I also need to concrete a little pad outside and install drainage under it for a downstairs loo before I do, so it will have to wait until it's dried up a bit first. In the mean time I'l do a little maintenance on the oil boiler to keep it running until then and use the wood burner as much as possible.

But that poses another question - to change to a Combi boiler or keep with the hot water tank system we've got? A combi heats the water as you need it for hot water, whereas the system we've currently got keeps stored hot water in a tank in the airing cupboard, indirectly heated by the water from the boiler.. I'm not sure I want to change the pipe work around to have the combi system as it means ripping up carpets and floor boards, although I'm sure a combi would be more efficient. We only use the hot water for washing our hands, baths for the children and washing up so having a tank might not be the best but if I start altering upstairs before Christmas it might cause a divorce! And it''s more work than I've currently got time for.
Thanks again for everyone's advice and experiences on the last post, I really enjoyed reading them and they all had some good advice in.
