  1. Not totally correct. When we installed our first biomass boiler and converted from oil to wood our fuel cost halved
  2. I'm not a climber or even make my living in the Arb industry but as an engineer can I suggest that it might be the point stress with metal to metal. Sling to a metal D shackle does no damage but D to D and you can see where the point of contact was.
  3. As you say it sounds like an immobiliser or ecu issue. Have you tried hot wiring the fuel pump.
  4. If you use that wood chip you will be very sorry. It will take some shovelling out as it won't go through your system. As said by (Niel I believe )use dry chip or it will rot. Aim for 20%mc Hire a good quality biomass chipper such as heizohack or muzmax. Chipping brash can be difficult with these chippers though as the twigs can go through the screens
  5. You have two opposing forces at work. Basicly you need to make your flue draw better than your house. A warm house with an upstairs window or attic hatch open, the house being taller than the chimney, big cooker extractor fan are a few examples of things that could cause the house to have a good draw. Cold chimney, wind blowing down or blocked with soot will reduce chimney draw. Any of these could tip the balance the wrong way and cause smoking, the trick is to find which is your problem.
  6. Southern wood energy have a couple around that size if you ever need one. One mounted on a ridged and the other on an artic. Smaller intake one has 780hp. Can't remember the power of the bigger artic mounted one, but similar.
  7. Temperature is a more likely cause. When the temperature in the chimney is colder than the room then you could get a reverse flow. Our modern chimney on the cold outside wall of the house is more prone to smoking than the old one nearer the centre.
  8. No problem Mark. I was giving the leisure cutters point of view. It was bound to be at odds with most on here.
  9. I was pointing out that stihl specify 16inch can be used with that saw. I totally agree it would be slow but that's what they say. Perhaps you should get them to change their handbook.
  10. The OP is only cutting small trees and branches, his idea is to reach further into his saw horse not cut full bar length.
  11. Stihl say 30, 35, 40, or in imperial 12 ,14 or 16 If you are not cutting full bar length, if it suits your setup and youre not in hurry then personally I would give it a go.
  12. OK thanks. Perhaps we should have a chat next week. Even if we don't buy it I expect Mark ( euroforest) will.
  13. Whole new ball game then. When's the wood available?
  14. Hi Stihl Just had an email forwarded to me asking if I woulld be interested in 279 pines. Same job I guess Jon and Matt?. I know pictures can be deceptive but those trees didn't look anything like 1.5 m diameter. More like 1.5 metre circumference. Have you seen them?
  15. The Essex suggestion uses the same principle as mine on page 3 of this thread. Some paper on top to provide a quick burst of heat. It works try it.
  16. Cardboard burns too slow. What you need is a rush of heat from quick burning newspaper. You may still have a problem but try paper. My Rayburn doesn't draw well if it has not been used for a while but a good amount of paper gets the gasses going. Damper and bottom door wide open for a couple of minuites then its fine.
  17. Did you guys not know firelighters are the devils invention. Quick flame from newspaper works for me. Some on top of the kindling to flush the cold air out of the chimney if you have a problem. If extreme as above. Good flames cure most draught problems.
  18. We use a fairly good approximation to G100 chip in our boilers. Best is from a muzmax with a 80 mm screen but as you know G100 does contain fines. If your brief is no fines then you will need to put your output through a screen. (Sieve)
  19. Piece of cake then. Have you mastered down hand. Nice smooth even welds with no flux inclusions? Watch the weld pool and keep it as even as possible for a smooth weld. What size electrode are you using and what current setting are you using for downhand and vertical. Try welding a corner joint at 45 deg from vertical and once you have a decent run increase the angle slowly. Do NOT weave on your first run.
  20. MOD dockyard instructors method was single root run first then weave as above. They used to weld nuclear subs so he showed me the strongest way presumably. Never got to that standard though. Inclined overhead is reckoned to be the hardest. BTW
  21. Thanks Steve Im definitely an insulation fan but I have two to do, one rectangular and one round. It sounds like the second might be fun.
  22. For thick metal go up with lower amps as per CJ, point the rod upwards slightly and a slightly shorter arc length.
  23. Do you normally use vermiculite on an internal chimney? Apart from the insulation advantages presumably it will keep the liner steady when its swept.
  24. As far as I understand if you have a boiler stove or are in the habit of slumbering your wood burner it is far better to use 904. It is more corrosion resistant than 316 so will have a much longer life especially under unfavourable conditions. When you consider the difference in cost between 316 and 904 as a percentage of the total then the longer life easily covers the difference.
  25. We put a few detectors around a couple of years ago and found our house was in the slight improvement advised bracket. I drilled 110mm holes through the oversite concrete dug some sumps, linked them together then fed the pipe into a disused chimney. Extra underfloor ventilation would probably have been OK at our level, but as we were fitting a new floor in one room it made the job easy.
