Hi,

Does anybody have any experience of burning pressure treated timber on a log burner. I work for a shed company in Bedford which has literally skip fulls which I can have for free, so I ve been thinking about getting a log burner or even maybe a boiler but had seen some website saying don t use it but others saying it s fine. So any real feedback would be helpful.

Thanks

Ed

In a sealed fire the pollutants go up the chimney. You are safe.

Open fire, not a good idea at all.

I heated my 2 up 2 down town house with a woodburner most of the year, run of treated pallets and anything I could burn, chipboard, mdf, the treated deck we removed in the garden, FiL old treated shed, treated telephone post (they made your hands stink splitting those), painted skirting boards etc

5 years not a problem, sweep the chimney and enjoy the free heat.

If people say there is a problem, ask them if they have had a problem or have they just read about it. If they say it rots out your liner, ask if they rotted theirs out, or just read about it.

I don't know about a boiler system but I can confirm you are fine with a woodburner/ multi fuel stove. I also know of 4 other people who do, and have done for many years and they are fine as well.

P.S. I can tell you about friends dad who had a crack in his wood burner at the back and nearly died of carbon monoxide burning normal wood though.

Exactly this.

If it's an open fire, then don't do it. Sealed wood burner, go for it.

I don't burn it, as i thought treated wood contained Arsenic, is this not true?

It is illegal, and illegal for your employer to supply you with treated waste wood for this purpose.

Whether that bothers you...

Just read on the Arboriste forum that one tablespoon of the ash contains a lethal dose of Arsenic!

Now I burn all sorts of waste wood but only as kindling - I would never use it as a sole supply.

Burnt odd bits on mine which I've had over from projects. Never an issue.

I draw the line at chipboard, MDF, painted wood, etc. though. That said if the sh*t ever truly hit the fan and I couldn't afford to heat my house I'd be getting every bit of furniture I could lay my hands on off Freecycle etc.

Illegal?

May I ask which law covers burning treated wood in your domestic woodburner? I have never heard that before and can't anything about it.

Thanks for the replies.

I am also interested, why is it illegal to take off cuts of wood and burn them?

AIUI it is commercial waste, therefore you need a license to get rid of it and a domestic user won't have a license.

Technically, you need a Waste Carrier's licence to even take them off the site! Not something I'd worry about.

Edit - beaten!

A step up from that - the company has a duty of care to make sure its waste is disposed of by licenced contractors. So they'd be in a lot of trouble (ie a very big fine) if this came to the attention of the authorities.

I'd happily take it, people all over the country do it with old pallets, etc. offcuts of timber and the like aren't really what the legislation is aimed at - they are after larger scale stuff like fly-tipping, or hazardous waste.

Let's wait and see if you succumb to COPD later in life before taking that as 'proof' shall we?

It depends what kind of waste it is - anything from sludge from the bottom of a fire reservoir, to mixed petrol and diesel from people misfuelling, to scraps of wood, to horse manure - they are all covered. Can only be removed from the site by a carrier/processor with the right ticket.
That even goes as far as a farmer crossing the road with a load of waste to bring it into his yard, as I found out about a year ago!

Burn it in incinerators that achieve a temperature a heck of a lot higher than a domestic woodburner, thereby breaking down the nasty chemical compounds to a harmless level.

It doesn't matter what you have, it all goes up the chimney. If it didn't you'd end up with smoke and Co2 in the room.
If you do have smoke and Co2 in the room then get worried.

I wouldn't be bothered about burning a bit of treated wood, but I wouldn't buy a stove on the basis of burning it all the time though.
It also depends on what it's been treated with too, if it's green it's CCA which is Chromated copper arsenate.
