  1. Build it to the left of the roadway. The trees and bushes will offer some shelter from the weather and have bays opening to the road. On the other side, build 2 walls, Build a 2" frame and fix the inner 4" wide boards with a 3" gap and a similar outer wall (out of step so to speak) so that the inner gaps are covered. You can cover the bays with skip nets linky I'd also be tempted to build a 'saltbox' roof rather than a standard A frame. I wish I had the room to build something that size...
  2. How hot does your indian stone slab get ? My old stove got very hot underneath (it was just a cast iron box with a fire in it) but the new one (Stovax modern lined thing) doesn't. My first stove I fitted inside the fireplace which I just tiled after removing the old open fire. The tiles looked fantastic for a year or two but then started to lose the glaze and crack. There was a small concrete hearth under the fire and I simply made up a wooden forma with 17 x 30mm lath screwed it flat to the floor and filled this with concrete and laid the tiles on top. I changed them for a piece of 30mm thick slate, this fits into the old fireplace and stick out into the room by 300mm. I think a 900 x 600 slab is around £60 and it's relatively easy to cut. I used ordinary tile cement to stick it down and mixed in some slate dust for grout.
  3. I dsoes say that you have a tertiary air system but I can't see any reference to where this is controlled. The DEFRA approval is linked to a system which doesn't allow you to completely close the air off (from entering the firebox) this is to ensure that the stove always burns off the gas/smoke. Most stoves I have come across have the ability to 'turn off' this facility (if there) or don't have it.. I can't find it in your instructions ??
  4. Aha, you have a non DEFRA stove whish doesn't employ the secondary burn. On yours. Primary air is from the bottom and secondary is down the glass (airwash). Once warm the primary should be closed and the rate of burn controlled by the airwash (your secondary). If both were shut the stove would suffocate and go out so you always need a little coming in from the top. Therefore your are right ""The net result if I did close it off would be I'd have to leave the secondary more open to get the equivalent flame .. is that right?? "" yes
  5. I think we need to get some of the terms agreed here. The Primary air (Pa) comes in underneath the grate (on a multifuel), at the bottom on a woodburner. The Airwash (Aa) comes from the top (often through the door frame) and washes down the glass. The Secondary (or Tertiary or Cleanburn) air (Sa) comes in behind the back air brick and enters though some holes which are around 2/3rds of the way up the back brick (or on the sides as some do). This air enters via a closed section that often runs down the outside back of the stove and is therefore heated prior to entering the firebox. The Cleanburn/Tertiary/Secondary (Sa) air is not often controllable when the fire is burning. Its via a fixed aperture that can be varied by a flap that is bolted in position. Some stoves have separate Pa and Aa controlls, mine has a single 'lever' that when fully open allows air in via the Pa and Aa vents. Pull it to the next notch and it shuts the Pa fully, Aa is fully open, pull it again and it closed the Aa and the Pa. The Sa is fixed and is always letting in air. Hope that makes sense ? In short the secondary air (Sa) is not controlable, the lever(s)/Dials alter the Primary Air (Pa) and/or the Airwash (Aa). Once the firebox is hot enough I close both my Pa and Aa fully, only need to open these if the temp falls (ie I put cold wood in).
  6. If you are looing for a cast iron box with a fire in it check out clearview stoves For a more technical stove a brick lined, steel, firebox is the way to go. The difference (I have owned both) is like a Land Rover verses an Audi TT. My current fire is a Stovax, it has a similar 'issue' with ash falling out to @roys Flavel, Stovax don't care either. Both were likely designed by some aerodynamisist stting in an office who still lives with mommy in her gas centrally heated Wimpy box. The Stovax has a cast iron door and they supply a loose top (ie it lifts of ...) in cast iron. It's a good stove and chucks out a fair amount of heat quickly, certainly faster than the old Clearview did. The stove does cool quicker but then it's less only half the mass.
  7. No need to apologise, we are learning ... I was trying to simplify ... there are 3 ways the air gets into a wood stove (not counting opening the door). Pa - Primary Air from the bottom of the stove in the case of a multifuel, under the grate. Aa - Airwash, often directly above the top of the door/glass Sa - Secondary or Tertiary or Cleanburn air which arrives preheated, through small hoiles in the back of the stove 1/2 way up the firebox. Typically you have active control over the Pa and Aa whilst the Sa is pre-set (although it can be varied when the stove is cold). @Jimmy101 it looks like your Sa isn't letting any air in at all. You do need some and then you can close the Pa and Aa down fully. In that state you will see the air 'burning' above the logs, If the stove isn't hot enough (it is in your vids) you would see black fingers in the flames above the logs as the cold air punches through the flames. You are very close. Crack the Sa open a little (25%) and then you can control the fire (once its going up to temp and the Pa shut) with the Aa open 5 to 10% If the flames are raging above the logs then shut the Sa to 10% If the fire dies off to nothing (with Pa and Aa shut) then open Sa to 50% It's a balancing act - you're close
  8. Well that clears that up then
  9. That looks ace .... is that a lump of granit on the top ?
  10. Got mine sorted now - there is a vid of it running 'here'
  11. I think we need to get some of the terms agreed here. The Primary air (Pa) comes in underneath the grate (on a multifuel).

Some stoves have separate Pa and Aa controlls, mine has a single 'lever' that when fully open allows air in via the Pa and Aa vents. Pull it to the next notch and it shuts the Pa fully, Aa is fully open, pull it again and it closed the Aa and the Pa. The Sa is always letting in air. My Sa is possibly a bit wide as the gasses are quite turbulent. To get the fire to burn as per the video, I almost close the Aa (leave the Aa slightly open and have the Pa shut). The fire has been on for a while (20 mins ish) to get to this happy state with the Pa shut and the Aa open, then I start to nudge the Aa shut and watch the gasses ignite and the logs go from yellow flames to a red glow. It happens slowly though. Like a turning a big boat. Once its in the right position it stays like that for a while. Dry Oak or Beech last longer than S Birch or Chestnut and longer than Pine or Larch. When I add more wood I need to open up the Aa (as the freshly introduced wood cools the internals of the stove) and after a few minutes nudge it closed so that the Sa takes over (becoming the dominant). Wet wood kills it and it takes longer to get to the happy state. Oak takes longer than Pine. The stove has to be hot for it all to work. Mine is a nominal 7.5KW and to get up to this output takes around 20 mins of intense burning with the Aa fully open. @Ratmanhas mentioned the DEFRA smoke control kit. This 'setting' always lets Pa in, it won't let you shut it down, however, this kit is normally a plate that can be removed. My stove (as an example) came with this plate (called the 'Smoke Control Facility') in a bag with instruction that it "must be fitted to meet the requirements of a smoke control area". If the 'kit' was fitted I wouldn't be able to get the stove to burn as in the video, the Pa and Aa would overide the Sa. Hope that makes sense ?
  12. Here's my new fire going strong, not flat out but burning well. You can see the logs and the yellow flames and then above the tertiary air burning the gasses. Initially I had the secondary/tertiary air vent fully open but hacve found that with it closed down to about 1/2 and with a little primary/airwash I can find it's efficent/happy spot. I am still learning and may close the tertiary air down a little more to get a more 'lazy' effect. 20201126_203320.mp4
  13. I like detail like that .... Each stove has a personality which needs to be understood to get it to burn happy. Wood fires burn from the top down, they (as @openspaceman said) don't need air coming from underneath. Once the firebox is hot enough you just need to trickle in enough oxygen/air to ignite the gasses and keep the temp up. The body of the stove passes this heat to the room so you only need to maintain the inside heat to allow this convection to take place. Roaring fires and lots of yellow flame isn't what a stove is about. After a while you should be able to maintain this state for an hour or so without adding more fuel, its a balancing act. Some stoves are more tempremental than others but it's most rewarding when you find that sweet spot.
  14. The tertiary air should be adjustable (?) on my Stovax it's a simple sliding plate that block off the rear inlet. Push it right in and it's shut, pull it out a few mm and there is a small gap which grows to around 100mm long by 15mm high. It sound like you have a really good draw from your flue so you probably only need it to be open by a very small amount. If you take the top baffle out and then the side/rear firebrick you should see the hole ? If you have too much draught a draught stabiliser may be needed. instruction manual
  15. 22 .... i'd melt I have the central heating (oil) keeping the house @ 14 degrees from around 06:00 to midnight and light the stove in the afternoon/evening which gets the house up around 17/18' depending on whats temp it is outside. Shut the doors and the living room get up to 26 in about 20 mins. at which point i'm opening all the doors again tout-suite. With no stove i've got the heating up at 16 in the evening but I cringe when I think of howmuch the oil the boiler is drinking ... A Brynje string vest is what you need, you'll save a fortune
  16. On the Stovax the 'smokless zone' control is part of the primary air feed on the bottom. Essentially it stops the slider from closing fully so there is always air getting in below and to the sides of the fuel. There is a small stainless plate supplied with a flat edge that replaces the one (already fitted) that has a notch, fit that and it will always get air underneath. The hole on the back allows air into a sealed void behind the rear firebrick and enters the firebox through a row of holes 1/2 way up the firebox. This supplies jets of (hot) oxygen which ignite the gasses above the logs. When you shut the primary supply down you stop the supply from below and it only come in through the jets. I haven't fired this one up yet and it will take me a while to figure out what it likes and how it burns.
  17. Cast top is part of the stove ... "oops sorry" said the seller "we forgot to send it". Just cleaned the chimmney today so will be ready to fit the 90 T and pipe up into the chimmney void and commission in the next day or so. If I could just order a few more days mild weather please ....
  18. Sorry for the lack of responses, there was a routing issue somewhere and I couldn't get to the site, still I got the new stove on Sat and spent the day (trying) to build it. I was quite surprised at the quality and the thickness (or lack of) the steel. 'Must be bolted to the hearth' is says, thats odd I thought, but the door is heavy and when fully open the stove is easily tipped .... i'm tempted to hand something on the back rather than drill the slate. The tertiary air comes from a hole in the back controlled by a plate that slides across and is held in place with an M8 stud and 2 nuts. Being a multi-fuel you would need to close this down when not on wood or if you needed to do an overnight, which, with a hot stove, would be very difficult to do. Bit of bad design there Stovax. The top is really thin too (2.5mm) and apparently there is a cast top but this could be an extra (???) cos it wasn't with the stove.
  19. Yes, Stoves are (not) us should be avoided at all costs, I bough the same stove from a dealer in Wales, who didn't avoid the truth and will be delivering on Moday/Tuesday. The stove i've just sold was a fire, on a grate, in a cast iron box called the Woodmaster 2 from Countrykiln < linky > which was crude but effective. On full chatt it melts the snow off next doors roof and has probably contributed to global warming. I reminds me of my old Herald Vitesse which had a go pedal and a slow down pedal, with not much in between. I've come across several more modern stoves, lined, with tertiary air and responsive air controls that work and have marvelled at thier controllability, thier economy (wood in heat out) and the lack of ash. I've had a few stoves over the years and they have all been pretty similar, a fire in a box. I've never had one with secondary air or lined but I have friends who do and recently stayed in a small cottage near Inverness that has a Parkray Aspect 6 and was well impressed. So I have settled on the latest Stovax Vogue Medium < linky >. It'll tick over nicely around 5 or 6kw and I can up the anti to get circa 11kw for when I really need to open all the windows and sit around in my Bermudas'.
  20. I have an Oil boiler which heats the water and warms the radiators and had a 15KW stove in the living room which on full chatt heats the whole house nicely. I say 'had' as I sold it on Monday having ordered a new more modern stove from 'Stoves are Us' last week on a '7 to 10 day delivery'. Which (it transpires) was foolish .... Having not heard anything I called 'Stoves are Us' (to chivvy them along) only to get an eMail last night stating that they "can't deliver until mid December and actually couldn't guarentee a delivery before Xmas ...." Stoves are Not Us" seems more appropriate then ? "I'll have my money back please" I requested, feeling somewhat peeved that they sold me something that they didn't have, "No" they replied "it will take us 14 days to refund you"..... They were quick to take it (under false pretences IMO) but are now hanging on to it like Trump to the White House. What a Cunch of Bunts. The bloke I spoke to on the phone seemed to think it was perfectly OK for them not to deliver until after Xmas and that it was wrong of me to expect them to give me my money back. Anyway, I have one coming from a more honest company next week which when fitted will be my main source of heat
  21. My pennies worth is that when you are milling your main consideration is power/weight, when you are logging/felling it's weight/power. I'd reccommend a Motorsäge 660 or the newer 661
  22. Yes. Triangular gussets to support the rear pin carrier to the bed.
  23. Graft it across to some root stock ... apple tree grafting
  24. Thats gorgeous that be ?
