  1. I have an old swedish (Husqvarna) wood oven that I am thinking about installing into my kitchen I am currently buidling in UK. The installation would be a standard set-up for such ovens in Swedish households (see photos, 'luftspalt' is airgap). However as these are not common in the UK I am wondering if there is any issue with UK building regs and such a set-up, or if anyone has had expereince with similar style installations? Thanks
  2. Given the direction consumer demand is going I would imagine this sort of set up would sell well. All the packaging is natural matrials so can be composted or used as kindling.
  3. Poor wording on my part, I meant the canvass bag holds a days worth of firewood. It holds about a 1/3 a barrow bag (anymore and would struggle to carry onehanded). The bucket holds 2/3rds of that when full and the remaining stays in the bag in the porch until around 6pm when empty that in the bucket and get another load from the woodshed. I find it's enough firewood for a 8kw stove to keep a single glazed, single storey, 2 bed stone cottage at 20-24 all day.
  4. I use an old metal washing tub bowl. It looks the part, holds a days worth of wood and doesnt allow any debris to fall through. The tub is just for storing though, I use one of these to carry the logs in as can carry it one handed: Esschert Canvas Fireplace bag. The box for the kindling is a cheap £5 IKEA job: Knagglig pine box.

    Pensions

    So one year on, any changes in pension/retirement planning?
  6. If you want some bedtime reading on the biodiversity value of sycamore in UK woodlands: The ecology and biodiversity value of sycamore (acer pseudoplatanus L) with particular reference to Great Britain
  7. Are you coppicing the lapsed stand in the photo, and if so do you expect it to regrow? We have a few lapsed coppices the same size but are hesitant of coppicing as concerned they won't survive. Enjoying the thread and the nice structure to your posts. A mix of first half educational then second about your own experiences. Would make a good book/memoir perhaps.
  8. You mean the 'Wood as Fuel: Technical Supplement for Fuel Suppliers'? Should come up through Google Alternatively there are some free copies of the 'UN FAO: Wood fuels Handbook' online which should help.
  9. For that budget I would suggest the Makita ea4300 over the 135 or 181, can pick it up for £235 (plus spare chain) from Fastfix.
  10. Might cost a bit but may be worth it comparing it to the outlay on your project (and that's not just because an old colleague is one of the authors). For example it talks about the growth rate, soil requirements, also the poor frost tolerance of E.nitens, such as the trial at Thetford were it failed completely, and how important the provenance of the seedlings is with regards to such tolerance.
  11. Interesting project. If you've not already I would recommend a read of this paper: The potential for Eucalyptus as a wood fuel in the UK (Leslie et. al., 2014).
  12. This analysis might be of interest to you and the OP; Long Term Carbon Account for Forestry at Eskdalemuir It looked at the long term carbon impact of a change of land use from upland sheep farming to conifer forestry in a Scottish farm.
  13. I think there is some misunderstanding about how woodlands store carbon. The main store is not in the trees but in the soil. See the graph from Dewar and Cannel (1992) Obviously if planting the potential to store carbon in the soil depends on the previous land use. If replanting a forest, organic soils or peatland than there would be little or negative storage, however if planting on agricultural land or heathland than there is substantial build up which remains even after clear fell harvesting, as the graph shows.
  14. First, I wouldn't worry about Cannell's papers being out of date. The methodology is still sound. Second, although species is important, there are other factors that can be just as, if not more important such as yield class (Bateman and Lovett, 2000) and forest management (Jandl et al., 2007). For specific values and figures (and general reading) I would recommend; The social value of carbon sequestered in Great Britain's woodlands (Brainaird et al., 2009) Carbon sequestration in the trees, products and soils of forest plantations: an analysis using UK examples (Dewar and Cannell, 1992) Long term effects of whole tree harvesting on soil carbon and nutrient sustainability in the UK (Vanguelova et al., 2010) The carbon pool in a British semi-natural woodland (Patenaude et al., 2003) Carbon storage and sequestration in the forests of Northern Ireland (Cannell et al., 1996) Estimating and valuing the carbon sequestered in softwood and hardwoodtrees, timber products and forest soils in Wales (Bateman and Lovett, 2000) Sitka spruce (Picea sitchensis) forests in Atlantic Europe: changes in forest management and possible consequences for carbon sequestration (Mason and Perks, 2011) Carbon pools and sequestration in forest ecosystems in Britain (Cannell and Milne, 1995) How strongly can forest management influence soil carbon sequestration? (Jandl et al., 2007) In short though I believe the summary from Dewar and Cannell (1992) is still applicable today; "If the objective is to store carbon rapidly in the short term and achieve high carbon storage in the long term, Populus plantations growing on fertile land (2.7 m spacing, 26-year rotations, Yield Class 12) were the best option examined. If the objective is to achieve high carbon storage in the medium term (50 years) without regard to the initial rate of storage, then plantations of conifers of any species with above-average Yield Classes would suffice. In the long term (100 years), broadleaved plantations of oak and beech store as much carbon as conifer plantations. Mini-rotations (10 years) do not achieve a high carbon storage."
  15. Judith Curry gets no media coverage? Just the other day she was found to be the 4th most visible in terms of media coverage of all climate change speakers (out of the 750). In fact deniers and skeptics get 50% more media visibility than scientists (source). The BBC as a perfect example of this lack of editorial rigor. She has also testified before the House and Senate on multiple occasions. She also doesn't say it's all a hoax BTW. Apart from that your analysis is spot on.
