I have seen some fireplaces in US (I am from Poland) and outside of northern states they are all decorative pieces not designed to heat the home.
A good fireplace is completely closed (yes! no fire visible!) and is built to recover and store as much heat as possible.
* the fireplace must be enclosed completely so that it is possible to regulate amount of air going inside and especially to close it completely and SAFELY when you go to sleep. You need to close it so that it does not suck air out of your house. The fireplace stores heat but it does not make any sense if, once it burns out, the air takes all that stored heat out.
* the hot gasses go through a complicated tunnel (not directly into chimney) to heat up a large amount of bricks made from material that has high energy capacity. That's why here in Europe we don't tell silly stories about Santa coming through the chimney, because that would be totally ridiculous. He could just as well be coming through water pipes, it is just as accessible.
* the fireplace is built on a steel bed so that you can easily take out the ash WHILE it is burning. Also, it supplies the fire from beneath which makes for much better heating.
* traditionally, if you made effort to keep fire on throughout the day, you want to make as much use of it as possible. That's why you will see these frequently performing multiple functions: separate space for oven, large top to be able to heat multitude of things, maybe even place to sleep (that especially in really cold climate in Russia, in Poland much less popular).
Here are pictures of traditional fireplaces you could expect to heat well:

The first one is something you would expect heating the kitchen and the main/dining room and provide most of the heating for the house throughout the day.
The second one is something to put in individual rooms that are too far from the kitchen. It is easy to light it up and it heats extremely quickly but also stores absolutely no heat.
