Fireplaces and wood stoves simply are not as common as they were only a few decades ago. Because of modern building codes, most that get damaged by earthquakes get removed or replaced by pellet stoves. The orchards that once provided so much inexpensive firewood while they were being cleared for urban development are now gone. The wood yards in the relatively arboraceous outskirts of town are farther away. Many municipalities have established ordinances to limit smoke, although this is not a problem if well seasoned wood gets burned properly, and only means that fireplaces can not be used on ‘spare the air’ days.
Firewood can be purchased from tree services that need to dispose of wood anyway. Because it is only a byproduct of tree work, it will likely need to be stored and seasoned the year before it is needed, just like orchard wood. (Firewood from wood yards gets seasoned before it gets sold.) Some types of wood that are often mixed in leave a bit more residue in chimneys, necessitating more frequent chimney sweeping. Realistically though, chimneys should be cleaned regularly anyway.
Because firewood is perishable, it should be obtained annually, in quantities that will be used in a single winter. It can rot if stored outside too long. If stored in a shed or garage too long, it can get infested with rodents. Besides, too much firewood occupies quite a bit of space.
Synthetic logs (made from compressed wood byproducts and fuel) are an effective, clean and efficient alternative to real wood that do not need to be seasoned. Each log burns about as long as several real logs, and produces about as much heat, so only a few go a long way. They are always available from supermarkets, and can be brought home with the groceries. Pellet stoves that consume fuel pellets that look like stove food are even more efficient. However, there is no substitute for a fire with real wood in a real fireplace or wood stove.
There are fewer fireplaces after every significant earthquake. Removal of a damaged chimney is probably more practical than repair, particularly if the fireplace does not get much use anyway. Wood stoves sometimes get removed simply because they are in the way. Modern building codes forbid their return once they are gone, and also forbid them in new construction.
The few surviving fireplaces and wood stoves do not get used as regularly as they used to. It seems that no one is around the home long enough to tend to a fire. Orchards that provided so much affordable firewood as they were being removed for urban development are gone now. The outskirts of town, where trees and woodlots might be found, are now more than a short drive away.
Firewood can still be purchased from tree service businesses that must dispose of the wood that their work generates. Because such firewood is a byproduct of urban forestry, it is an unpredictable mix of all sorts of urban trees, and must be procured early in the year to be seasoned by autumn and winter. It is now much too late to purchase green firewood for this winter.
Almost all types of urban firewood are comparable to more traditional types. A few types deposit more residue in chimneys, so that chimneys need to be cleaned more frequently. Firewood from woodlots can be surprisingly more expensive; but it burns cleaner, and is already seasoned. Many woodlots would be pleased to deliver firewood that is ready to burn now.
Firewood is perishable, so only slightly more than enough for one year should be procured annually. Any leftovers can rot if left out in the weather too long. Firewood last longer in a shed or garage, but takes up too much space, and can be attractive to rodents.
Synthetic logs from the supermarket happen to be more efficient than real wood, and do not need to be seasoned. A single log burns longer and cleaner than a few real logs, and produces as much heat. However, they are individually very expensive, and are just not the same as real firewood.
