We have posted recently about firewood, green or dried.
Of course, it all depends on whether your fires are for pleasure, comfort, and ambience or for the BTUs. We have an old wood stove in the kitchen which provides tons of heat, but my fireplace in the den warms that little room up very effectively, to the point that I have to open the window.
Fireplaces do radiate heat, just much more ineffectively than stoves.
What wood to burn? Any wood is good. Some people are too afraid of burning fir and pine, but they are excellent, produce wonderful smells, and probably produce less chimney creosote than slower-burning hardwoods. However, if you keep a home fire burning as we do, you must have the chimney cleaned at least twice per winter, and ideally once per cord or two whatever the wood. Chimney fires are the reason so many churches and old houses have burned down in New England.
Generally speaking, the hotter the fire, the less creosote condensation in the chimney. Here you can read all about chimney creosote.
I have read that it takes a year to air-dry unsplit green wood, which can contain over 50% water when freshly cut (dry wood is around 25% water, depending on where you live). I burn green wood sometimes once I have a good bed of coals and don't want a blazing fire, but it certainly does not burn as hot as air-dried wood. I don't care because I am not reliant on wood for heat except when our power is down.
Here is some good firewood info from the Master Sweep.
Here are some good data about firewood
Info re the Franklin stove
Around this time (1744), the deputy governor of Pennsylvania, George Thomas, made an offer to Franklin to patent his design, but Franklin never patented any of his designs and inventions. He believed “that as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours, and this we should do freely and generously”
Info re the Rumford Fireplace
Brick-lined chimneys? They are obsolete. Best thing is to line them with stovepipe.
Always bear in mind that every time you light a fire you are producing CO2, killing Gaia, and destroying the planet. Coal and oil, after all, are just very well-seasoned old wood. If you truly love Gaia, you would do without mechanized transport, or horses, or A/C, heat, and the internet.
