The Daily Mail reported that wood burners give out more pollution then diesel fuel yet never made any mention of power stations giving out pollution, they told the Mail they don't so thats okay then, Suffolk has a waste wood burning power station system that use's all the old wood from council run dump sites, Plywood, Old varnished furniture, Chipboard, MDF that has been proven when cut or burnt gives of cancerous forming dust, the next close thing to a wood burner is a pellet burner, which burns sawdust and waste Chipping's that are compressed into pellets, yet forgets to mention the sawdust has got many chemicals in it to bind the wood together in the first place, where does this pollution go.
In the UK many homes don't have mains gas, have an oil boiler, any pollution from them? These don't have a DPF filter on them like diesel cars do, which 50% of are getting blocked.
A correctly fitted wood burner that is burning logs at a high temperature gives very little pollution of, fill it with pallet wood etc then a different story.
Even having a portable gas heater should have some kind of air vents in the room or near by, most people in the UK who have died from carbon monoxide poisoning have been killed by faulty gas boilers, even then you could argue that having a carbon monoxide tester in the house might have prevented these.
