  1. Exactly. Now try the same in a 3 MW boiler. Now that's a bang
  2. We needed proof of our wood being from a sustainable source to claim RHI. I just asked euro forest and they provided what was necessary. 1 phone call, no hassle. I'm sure all the big suppliers do it all the time.
  3. If you have no draught and no flame the wood gases will be driven off by the heat then if a flame appears you will get an explosion using whatever oxygen is left in the boiler/stove/flue. The wood boiler at the Eden project blew its stack off amongst other things and was offline for a considerable time. In the early days an inexperienced operator relit our boiler and fed too much chip in, smothered the flame and when a flame appeared that lit the gases there was a damaging explosion. This is fact so be careful. Do not totally starve the fire of air and maintain a flame is the safe way.
  4. A large wood chip boiler slumbers by feeding a small amount of chip every 1/2 hour or so. No fans running but a big boiler and small amount of chip. Normally a small amount of smoke is seen from the flue when in slumber mode so some natural draught is occurring. I suspect some air flow would be needed otherwise you could have a situation described by the briquette seller. Always having a flame to burn off the gases is safest.
  5. Your biggest problem with wood chip will be the feed system. Small boilers normally run on pellets which are more expensive but easier to feed. What size boiler do you need?
  6. I agree it certainly wasn't the same. However a few years ago I had a chat to a tanker driver while he was filling our tank. He told me he filled from the same tank at the depot for all customers. Our local Tesco has BP ultimate on the pump so if it wasn't wouldn't they be in trouble for trade description? Normal BP regular on the other. Possibly at otherTesco stations their pumps have different fuels but I assume my local to be normal BP. Not saying your wrong TCD but could it vary area to area?
  7. Simon to be safe you should do as I suggest. I was reluctant to mention this but a member of my family left it too late.
  8. My local machinery dealer hires one of these out. Good machine apparently.
  9. Probably over work but it might pay to have a checkup by your GP. If you have a problem then catching it early might make a big difference.
  10. Exactly the same fuel I expect. Many times I have seen a BP tanker filling Tesco tanks. Seen BP there almost as often as Tesco tankers. BP plastered over the nozzles so I would say BP fuel in our local Tesco. Never had a problem with pay at the pumps and I always check my credit card statements.
  11. Two main advantages as I see it. Almost certainly its better for in your face machines such as hedge trimmers. Health benefits for that presumably and also its allegedly better for low usage machines with stale fuel problems. Not got my head around spending the extra for thirsty strimmers yet as I've never had a stale fuel problem even though my usage is very intermittent also the exhausts exit behind me so no heath issue I can see. Saws might be more of an heath thing but I've never noticed any ill effects. Eddie has yet to convince me but I would be interested in any scientific reasoning on saw usage.
  12. We've had trouble with husky pro gear to prove any make can be wrong. I've had faultless Chinese gear but I wouldn't say it was better than husky. Its just the luck of the draw. Better the name the better chance you have, simple as that.
  13. The garage was talking about a twin turbo if that makes a difference. 6 hours work to change turbos after the body was off ? Seems a lot to me but not my vehicle so I don't really know the full story. Thoughts?
  14. I've had lorries on mine. Oil stains you could lift a brick and replace with spare. My first house had a gravel drive and my experience with that is probably why I dislike them.
  15. Looks are a personal preference so I think we can agree to disagree on that one. As said angular gravel is better as it locks together to some extent. Mud, silt and any pieces chipped off the gravel will build up over time and it will eventually become clogged. I have seen several drives that look like 20mm to dust with a mix of mud thrown in for good measure. Brick pavoirs are the way to go if there will be any need to take up for trench or stains. My main point is value of the property. A good drive will probably increase property value by more than the cost to do it, and as a bonus you get the benefits. This of course depends whether Simon wants to invest more money in his house or keep it for his business. Its another choice to consider
  16. You don't mention that you have changed/ checked the air filter or did I miss that.
  17. Personally I would never consider a gravel drive. Obviously a cheaper option but with looks to match IMO High maintenance to keep it rut and weed free, and if you are in the tree business would you not be bringing mud in on your tyres and truck? Worst thing there is for a gravel drive. As an alternative you could do it with tarmac or brick paviors. It sounds like you can do the base so for a bit more money either you or someone else could put something decent on top. You won't lose as it will put money on your house and also you will have the benefit of a proper drive with less maintenance.
  18. Use something like mypex to separate gravel from earth or whatever is underneath. Quick and easy and lasts.
  19. That seems to be the case around here. 1 refusal, 10 litre max, another didn't care. Tesco man came and checked what we were filling and said fine go ahead. 2 jerry cans and a few plastic. I used to think 5 Ltr plastic 10 Ltr steel but all have different views so it seems. As Jon says asda unmanned has to be the best.
  20. Gap of 0.5 mm I believe
  21. M Colbear Devon IH574 £2200 12 GPM good hydraulic pressure on those IHs as far as I remember.
  22. Would think. I have burnt 100% spruce but its bit of a pain. My spruce is from big diameter trees so most of it has no bark which makes it worse. I have stacked it 50:50 with slab wood which is mainly softwood with a lot of bark so I expect it to be easier to keep the fire in.
  23. It doesn't leave a good ash bed so it requires a slightly different approach to the fire. If the fire dies down there is a real danger of it going out, as its done in my Rayburn a couple of times. Mix with something else unless your customers are aware of the problem. Luckily mine was free otherwise I would have been grieved to have paid money for it.
  24. If you are considering chipping it for biomass it needs to be dried. I would not buy the chip unless it had been left until all the resin dries. 3 years depending on diameter? The resin on the chip will stick it to the sensors and stop the boiler feed. You might sell to someone unfamiliar with biomass chip problems but those who know will not touch it until the wood is dry and the resin is solid.
