WoW, Openspaceman, All good interesting very relevant stuff, apparently a bit mare:lol: to burning wood-chip than meets the eye. m

Bloody hell!, that things like a giant Mechanno set. Wonder what the purchase cost was way back in 1995? Frightening I suspect. Probably an overspecced Council vehicle designed by Committee:001_rolleyes:

Beautiful and beautifully thought out and executed, (and btw,I have teased the Mrs. about buying an old,extra extra large but no longer roadworthy Hymer motorhome and parking it up as our retirement dwelling) But? Wot's it weigh?, any idea? Noting the solid woodwork, jawbox sink and cast iron stove:lol: Very homely friendly feel to the interior, proper jealous. m

I like Spud's "life is tough, but it tougher when your stupid" I also liked the comment by yon grizzled old logger on Axemen "Ye caint fix stupid"

3rd valuation is the critical one What is it worth? to you? Or to the other bidder? cheers M

I reasonably imagine it is exactly the question of the small scale of a domestic installation making the necessary technology too expensive for to realize any cost savings. The other rub is wood is known to burn at very high temps, normally relying on a bed of ash to insulate the metal grate, or in the case of a logwood gasifier, the "grate" is ceramic and can sustain the high temps. I am not sure how they get around this in wood-chip burners. Do they rely on the damp (30% for domestic?) incoming chip keeping the grate cool? I dont know. PS Surely the other difficulty is storing the damp chip, it will surely heat/compost if stacked in a bin or store. But again on a commercial scale it is practical to have lorry or trailer loads delivered on an ongoing basis and being consumed at such a rate as to prevent any composting/ heating issues. Also practical on a commercial scale to have a fan blowing cold air through the heap. etc etc

I was and am aware of the particular/more onerous specification requirments for wood-chip to fire an auger fed burner. Leastwise at the domestic scale. Compared to general branch/brash disposal, and I never intended to attempt to burn arb arisings anyway. I also suspect that any chipper I am likely to hire locally will not be suitable for my particular requirments, being aimed at the tidy up/disposal market. So therefore required to buy one, at a substantial capital cost, even 2nd hand. So I will stick with the logs. cheers m

On that particular theme, I had hoped to pick up a grant installed/ripped out sosphicated log-wood burning gasifing boiler. At sensible money=scrap price. BUT If the RHI is "free money" that will allow me to install new boiler (but retain existing flue an other bits) IS it worth the risk. Any one seen nominal 50kw gasifiers for sale, windhager, hoval, froling, kob, any of the reputable makes. Regards Marcus

Well I retained the Wooster Bosh oil boiler. I run it during the summer months, for DHW only. 20 to 30 min each morning and off again until the next morning. For all the oil this uses Solar could not make sense. Cheers all marcus

Thanks all, prob made my mind up to stick to the logs. PS I really really should finish insulating the roofspace:blushing:, 1/2 the hairy molly is still in the plastic. Perhaps the Mice:lol: will have made a start for me.

I do keep telling anyone who asks (or can be persuaded to listen) (i) Insulate, insulate, insulate. (ii) Make sure your boiler, plumbing and controls are working correctly. (iii)Turn the thermostat back to 18 deg downstairs. (iv) Limit the running hours of the boiler forby, i.e. do NOT leave it stat controlled (v)Consider putting a logburner ( NOT plumbed in) in the living room. AND Finally do not EVEN consider replacing an oil boiler with a wood boiler. UNLESS One has an unlimited supply of free wood.

A fair point for a grumpy 54 year old to consider. I probably have 3 years put by at the moment, and would hope to keep this "buffer" in place as I roll forward. I have also attempted to avoid multiple manual handling for this very reason. But "logging" is the only exercise, other than dog walking, that I get, so I had better stick at it. cheers m

I normally keep the egg UP, and the eggcup DOWN. Seems to work for me. PS The Germanic bred Mrs. got these cunning Teutonic Thomas egg cups, with a built in saucer to catch the yolk spillage after over exurberent soldier dunking. Dammned Germans always playing with their soldiers I suppose. Or am I getting old?

I too saw an architect designed from scratch/no expense spared installation Hoval pellet burner in a very new, i.e about 3 year old high spec new build. Get ripped out and replaced by an oil boiler. About 5 year ago. So probably better to stick with the Froling T4 gasifying Logwood option. sigh.

I had considered a wood chip installation back about 8 years ago before I choose to install the logwood gasifier. I have "unlimited" "free" wood so it would not make sense to buy chip. I reckon if I either set the smaller dia logs aside for chipping, or split the larger to size to suit a smaller chipper, I could either preferably hire, or reluctantly buy a tractor powered 2nd hand chipper. I do rather fancy the "automatic" nature of the chip system, even if I had to transfer chip from a bulk store to a hopper, say on a weekly basis. The auto lighting system is a big attraction. I would also retain my 2000litre accumulator tank. However I understand these chip systems are better suited to larger, more commercial sized systems. For domestic use, it all seems to have swung to pellet systems. Must have a prowl on the greenbuilding forum cheers m

Chippers International Erm, I was aware of the brand, but it appears they are aimed at the disposal of brash by chipping.......as opposed to wood-chip biomass production. I would be feeding it reasonably clean lodgepole sans needles or small branches. I would rather hire a machine but this one came up in conversation today with a tree surgeon

For the about to be introduced RHI scheme in Northern Ireland. I got an accepted for a Froling logwood gasifier.............................but Am swithering about a wood chip system instead. I can apparently buy a Gandnia chipper for 6k 2nd hand. Are they any good, as a brand?, and are they suitable for producing woodchip suitable for the automatic boiler feeding systems? I take it substantially more capital investment required? Thoughts please.

Tee Hee, I stumbled across an unlimited free supply source yesterday, about a 1/2 mile from my workplace. A plastics re-cycling centre with loads, probably Ex seed potatoe trade, sitting lonely and unloved. OK Not "free", but well cheap and handy forby. Sorry:001_tt2: Marcus

Cept I just lift and swing the stuck Axe and attatched block and smack it back down the normal right/ way up way. Try once flat bottomed and centred, if that does not succeed, the next time striking with the front or rear lower face of the block to dislodge the Axe. Never yet failed, or indeed ever broke an Axe shaft either. Never invested in or used a Maul either. Before I bought the hydraulic splitter btw.

Bit like Army time Zulu time GMT European time Excercise time UK time (summer) UK time (winter) From hazy rememberances of TA Euro Excercises with some quite heated discussions as to what time ACTUALLY REALLY was. Which was quite pertinent when catching the Ferry to get back home

18 Sotoner, I believe the reference to "dumpy" bags is reasonably self explanatory, implying small or undersized. Btw the 0.73m3 is Sooooooooooooo nearly 1cu yd as to be aggravating (about 95%) And if one chooses to describe a bag a 1.0m3 it bloody well should be. But then how cognatively lacking is most of the population if they cannot figure 1.0m3 means 1m by 1m by 1m.

Well them dammned Yankees are a meddling again. Thanks Mac, I unnerstan that I picked it up in our farming press, probably cos some bleeding farmer misunnerstood the correct usuage. Now wtf 2000lb, was this some kinda early Yankee attempt at going "metric" Though I do know that until suprisingly recently our cwt varied between different regions/market towns, as in a cwt could be comprised of a different no of lbs. marcus

As fat as a fool and twice as happy. With a twice happy wife snuggled in beside me. (an three dogs in the bed and one beside) An keeping 2 weans at Uni an in motors. Also a final year failed Civil Engineer with a memory for mostly useless detail. (Sammy terzaggi and krepner trego analysis and herman bernouliee an all that.) A prefectionist by psycometric profiling. (With Jackdaws nesting in the chimney and also in through the rather large hole in the soffait above the front door) I also suspect I am dyslexic and somewhere on the autistic spectrum. At 54 no worries and I have ceased to give a tinkers curse how others percieve me. btw I prefer the company of most animals to that of most people:001_tt2: PS Me and the Mrs. just scoffed 1/2 a large box of Thorntons cos we run oot o Haggendaz.

Tsk tsk gentlemen. (i) Sand and aggregate is sold by the tonne ex builders merchants, the moisture content makes very little difference due to the free draining nature of these products. (ii) About 1.5 to 2.0 tonne per m3, hence the "odd" volume of a builders tonne bag. (iii) mass concrete being 2.4 t/m3 An imperial ton is 2240lbs being 20cwt by 8 stone by 14lbs in a stone A tonne is 1000kg by near nuff 2.2lbs = 2200lbs i.e. 20lbs "light" Or was sometimes referred to as a "short" ton. The intersnot will provide more exact comparisons and bulk densities. cheers marcus

Yes, I opted for 1.0m lengths (cos thats the way the German's do it), it makes for easy counting of volume I surmise. Should be ready in 1 year, or if split in the spring and covered, ready to burn in the following Autumn, assuming a reasonable summer and a breezy location. I imagine, especially if split to a not greater than 100mm diminsion. I could be over-optimistic though, but since I am running a gasifying boiler my logs need to be properly dry. Therefore I try and be a couple of years ahead of myself, bringing them into an airy shed, after a season outside.
