Go on then, the other 15% turns into cosmic rays?
The 85% does mean 85% of the heat enters the room (the measurement is done by subtracting the energy in the flue gases, calculated from their temperature and volume), but it is under specified conditions and will be affected by the length of exposed stovepipe, whether it's in a chimney recess, etc as well as the burning conditions. A stove with outside air intake (which is very much worth it), on a free-standing hearth and with the maximum permitted uninsulated stovepipe inside the room will be the most efficient.
Nothing is 100% efficient. Including gas. Sarcy bleeder!!!Go on then, the other 15% turns into cosmic rays?
An air inlet under the grate is primary air and not for wood burning, only for coal or for lighting up. There must be a fixed secondary air inlet, or you have a coal-only stove.
I am not wrong i have never been wrong...ever. how often do you actually get a perfect burn? They (the manufacturers) use volkswagen to do there testing. I certainly don't get a perfect burn over night. Well I assume that as I put one big log on making sure it has bark all the way round. Then close it down and it always stays in. Nobody gets a perfect burn unless its measured by volkswagen!!I was going to post that what Notafettler said was wrong but you beat me to it.
Our Charnwood C4 only has one control - a single knob under the door that sits in one of three notched positions (although you could position it between notches if you wanted). Full-out is intended for lighting or reanimating a fire. Mid-point is the normal running position and full-in is for a longer, lower burn. We rarely use the full-in, unless the fire is burning especially hot. We are paranoid about the flue temperature but always manage to run it in the indicated 'safe' zone - our sweep confirmed he was happy with the state of the flue and to carry on as we were.An air inlet under the grate is primary air and not for wood burning, only for coal or for lighting up.

Anyway I am off for 2 hour cycle ride to exercise the dog i will go on my electric bike with trailer. I will come back soaked but happy as the trailer will have at least half a days wood in it. Which I will add to the 2 years plus I already have and it will cost me nothing. Thats what you call efficient. Ner de ner ner!!
Used proper coal throughout the 90s and was in a smokeless zone ...neither the police nor council called round to tell me to stopWe can still use it here if we want - we are not in a smokeless zone. ...
Who has actual newspaper these days?
Rubbing it with the Internet anyone?
Newspaper ain't what it used to be... these days, the 'ink' isn't soot and therefore it doesn't have the magical cleaning qualities it used to have.Ostentatious waster that I am, three sheets of Lidl roll damped and then dipped in wood ash. Finished with glass cleaner and another sheet. Wood ash makes a very good none aggressive abrasive that cuts the tar and not the glass.

A little overloaded as I couldn't get up a grassy hill had turn back go by road. A couple of 10 inch long logs in each pannier as well.
