These stoves were fine in old houses with solid walls and enormous heat loss.  In a modern insulated house they would cook the inhabitants.

Not true, because they are only fired twice a day and the masonry is kept at a relatively low temperature to prevent cracking, the output is surprisingly low. The main problem is the low output in relation to size (they are just too big and heavy for modern houses)

Ours in Bavaria was fired up only  twice a week  Wink  perhaps 4 times a week  in winter ( down to 20 below freezing )  , but true Dhaslam   it was an old Bavarian Farmhouse ( 3 feet solid sandstone walls )

And thats why i cannot recommend them for low  heat needing houses , but there are super efficient maissionary stove  inserts available that can control the amount of heat going to a thermal store (buffer tank )  and heat your let me say 5 tons of clay around them   to keep the open living area warm , without touching the thermal store /radiator setup  in the morning

I know you all get bored with my German links   , but that one does 30 kw to water store and 1.5 kw to 4 kw (variable ) to the room ....  and burns twice the flame ( gasifying idea )

Hi DH
Curiously the first person who was famous for replanting trees was born about 10 miles away from StBC. His Was arguably the most famous landscape gardener of all time (certainly in these islands.) His name was "Capability" Brown. There is a move to do some landscaping herein Northumberland. Possibly your cousin could quote?

My cousin did his forestry degree in Scotland and there were  a lot of good ideas from lecturers there.

daftlad banging on about masonary stoves again.
a quote from the Missouri Department of natural resources

Size of Unit:
The masonry stove, as described in this publication, with a firebox exterior of 27 x 36 inches, is
large enough to adequately heat a 1200 to 1500 square foot residence, when insulated to R30
ceilings, R20 walls and R13 floors. This also assumes good weatherstripping, joint caulking and
double glazed windows. Heat distribution by directional fans or duct work will be required to
adequately disperse the heat that this stove is capable of producing. Twenty pounds of air dry
wood burned in a masonry stove will deliver approximately a net value of 112,000 BTU.
With the use of special sized firebrick or castable clay a vertical flue run masonry stove could be
constructed with an outside ornamental wall dimension of 25" x 25' x 6 feet high. Allowing for
safety spacing with a heat shield the masonry stove would occupy a space of approximately 39 x
39 inches. This is very similar to the space required for a large radiant heat style stove. The
weight of the unit would also be greatly reduced. The cost factor is uncertain as fewer but more
costly materials are required, also molds are required to form the castable clay.

this is a link to the full text

Presumably you're talking about plants rather than firewood? Then I've used Buckingham Nurseries who sell bare rooted trees at reasonable prices. I bought some hedging from them 5 years ago and they have established well. Mind you they did take 6 weeks to dispatch the order and it was very late in the season when they went in!

If you want Nothofagus Procera, which has been recommended on the Greenbuilding forum as a good fast growing firewood tree, then Heathwood Nurseries http://www.heathwood.co.uk/2004/fieldgrown.htm have them listed, although I haven't used them myself.

You may find that finding a local tree nursery is worth the effort, they will usually be cheaper than internet suppliers.

Having said that I've just found that the local nursery that I've used recently have a web site www.johnholliday.co.uk

Hi Stefan - I'm not sure exactly where you stay, but here's a couple of links for some sources North of the border....

Good luck,

Lightfoot.


PS,  you don't see (or should I say, I've never seen) much Sweet Chestnut in the North of Scotland - apart from being non-native, I guess it may be a bit cold etc.

Yes, I did mean plants. No local nursery, so will have to rely on good online shop.
Like to get stock from different suppliers.
Suppose it might be a bit cold for sweet chestnut, was hoping to grow just a few sheltered by other trees...

My nurseries here in Ireland deliver nation wide (ok when bigger orders  ) 

I planted  quite a few  Spanish /sweet chestnut here at the coast of Ireland  and its not growing too good (  quite slow and small ) , but still grows
