Ducted slow combustion: possible ?
My house a similar setup. Wood fire downstairs, pipe through the ceiling, and up through the next level, (which was a 20 year later extension) but they have not sheilded…
Insulation under tile floor?
My undertsanding is that the underslab stuff is not the best in most of oz as we do not really have the long cold winters where we need constant heat pumping out. Hence…

Ground source heat/cooling pumps
Thought some of you might be interested in this presentation at the Alternative Technology Association (admittedly at short notice).
He'd say that because he wants to sell you an oil-burning heater! The funny thing is, he's probably right about what he said. Air conditioners, on the whole are noisy.
Open Fireplace Designs
If you’re not interested in the heaters have a look at the designs of the walls holding the heaters, some of the best I’ve seen!
Room for thought.
