Only smokless coal and kiln dried logs are permitted now due to the new air quality regs. I would imagine that smokless coal will be phased out in the not too distant future due to the fossil fuel debate.

Logs do not have to be kiln dried. But they are supposed to meet a certain standard of moisture content. 

What dose the moisture content have to do with being permitted?

Because the supposed aim of the legislation was to stop people burning wood that emitted a lot of smoke - in other words, wet wood. People with money to burn buy kiln dried wood, the more MSE savvy either naturally season wood themselves or buy it once it has naturally. Kiln drying is expensive.  

But wet wood dose not emit smoke it emits steam

Burning wet wood also increases the amount of creosote forming in the flue. In addition, when the vapour condenses, it reacts with other chemical in the smoke (and the deposits already in the flue) to form acid which then eats away at the flue. On top of that, the particulate emissions increase dramatically.

If you want an efficient clean burn with maximum heat output, use well seasoned logs.

I know that burning wet wood dose soot up the chimberly a lot but not sure about what you are saying about polution though

It emits far more smoke per useful kWh of heat because much of the calorific value is wasted on evaporating water.

Meaning the steam goes up the chimberly with the heat from it and dose not stay in the fire place. still fail to see any evidence of polution

it’s also about the heat the wood yields when burnt. Nobody is dopey enough ( surely) to realise that wet wood is not warm wood? Also mentioned is creosote forming in your chimney. That is an excellent point. Ever seen a chimney fire? My neighbour used to burn anything,and ended up setting fire to his chimney and roof! 

I burn just about everything too! is the creosote the stuff that kills off plants and stuff if you put the ashes over them. (again fail to see any polution point)

How do you season them?

I used to think that the fire would heat up the water in the logs and the water would give off heat in the log burner so no energy lost

Is creosote flamable? dose it burn?

I cut to length, split, and then stack under cover outside. The pile remains like that for one to three years before moving the logs in to a shed in spring. Over the summer months, they get baked, driving the last bit of moisture out. Final moisture content is between 10% and 15%.

And in answer to some of your other questions -

The steam produced from burning wet logs just goes straight up your chimney and provides zero heat to the room.

Creosote burns. And when it does, it burns very hot and will trash your liner. When the fire brigade come to put it out, your room(s) will be ruined by all the water they use.

Do NOT burn plastic, waste engine oil, or treated/painted wood - They all release nasty, toxic chemicals (even if you can't see them), and is in breach of several regulations. If/when you get caught the fine is up to £50,000 and/or 12 months in prison. You will get the rest of us a bad name, and garner the contempt of those around you.

Off to add a new name to the ignore list.

Yes,it can set fire to houses.
