Hello all,

I've been doing a little research on this recently with a view to
installing such a system in a stone barn conversion in my back garden.
I'm wondering if some of you could confirm if I'm heading in the right
direction.

First I live in a forest where my next door neighbour Chansaw Chris is
a big fan. He buys and stores unseasoned logs at £30/ton from a guy
who clears railway enbankments. A 2 ton load will see him through a
year, he says.

OK. Now the barn is quite small but tall enough for 2 small bedrooms
and a shower room upstaris. I'd planned to install an electric shower
for safety and convenience. In all with a new build lean-to kitchen I
calculate a volume of around 150 cu metres, which I understand could be
serviced by a burner of 10-12kw capacity. The new floor is built on
insulation board and the walls will be battened and lined with similar
insulation.

I suspect the original chimney which appears to merge with that of an
adjoining barn won't be adequate and I'm leaning toward installing a
new one, built from Anki pumice components. The overall floor to
chimney pot height is around 5m and as I read it, the larger the better
for updraught in a short chimney, so I have the 200mm size in mind

The big question for me right now is this. Given that the bedrooms and
shower room will be directly above the room heated by the woodburner,
the stairs will be open and the kitchen addition will open directly
onto it. Do I actually need radiators?
