All fires needs oxygen to burn and heat rises. So, the fire will pull air into it and the heat and smoke will then go up the chimney. The result will be heat loss from the house, however, here will also be some heat added from the radiant heat of the fire.
If you really want to get heat from a fireplace, the best thing you can do is install a wood, gas, pellet or some sort of bio-fuel insert into it.

How do fireplaces conserve energy?
Fireplaces don't necessarily conserve energy. In fact, many fireplaces can actually be wasteful energy appliances if not installed, used, and maintained correctly. For gas fireplace owners, I would certainly suggest adding a fireplace blower or fan kit. A blower kit will pull cool air from the lower louver and force air up and around your firebox. The air is heated as it travels around your firebox or insert and is eventually expelled out of the top louver. Without a blower kit installed, your gas fireplace is nothing more than something pretty to look at. Sure, you get some residual radiant heat, but it's nothing close to what's need to heat an entire room. Adding a simple blower kit to a gas fireplace can save you hundreds of dollars a year in home heating costs.
How does a fireplace warm the house?
Fireplaces, especially gas fireplaces, don't really do much to heat your home unless a fireplace blower or fan kit is installed. A blower kit will dramatically increase the efficiency of your fireplace by helping to distribute the heated air your fireplace produces into your home. They have kits and replacement blowers for most major brands of gas fireplaces. Even some wood fireplaces.
Would a gas room heater be convection conduction or raidiation?
it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.
What happens to air as a stove heats it?
The air expands as it is heated this is due to the increased activity of the molecules composing the air. It also rises as its density is reduced compared to the cooler air in the room. The pressure of the warm air remains the same as that of the cooler air.
What will be the temperature of a woolen ball lying in a room of temperature of 20 C?
Unless it has been heated or cooled recently, it will of course have the same temperature as the air in the room - whatever that is.
Does burning a fireplace pull warm air out?
Yes, it certainly can. If you have a gas fireplace, I would certainly suggest adding a simple fireplace blower kit. They take the heated air created by your fireplace and force it back into your room. Adding a blower can save you hundreds of dollars a year in energy costs.
What are 4 convections?
the air being heated from a fireplace,air from a furnace,boiling water,the air being heated in a hot air balloon.
Why was an ancient Roman villa's fireplace in a room by itself?
Because they had air flow central heating (a hypocaust system) and the fire had to be in the place where that was and where the bathwater was heated,
How does a fireplace heat a room through convection?
With respect to gas fireplaces, these types of fireplaces typically do little to heat a room without having a blower kit installed. A blower kit will draw cool air in from the lower louver and expell the heated air out the top louver. The physics of convection still apply with any fireplace. The cooler dense air forces the lighter heated air up. A common ceiling fan can certainly help with this process.
Where does the oxygen come from when the log fire is burning?
From the air in the room where the fireplace is.
How is a room heated in winter?
There are several ways. From ancient times, we would have a fire in the fireplace, and the heat of the fire would warm the room. Many modern fireplaces have heat exchangers that run air through pipes in the back of the fireplace to blow hot air into the house without allowing smoke to get into the house. In Roman times, some wealthy people's houses had a "hypocaust"; a fireplace would blow hot air through passages underneath the floor. This heated the entire building, without the need to have fireplaces in every room. In the 1800s and 1900s, many houses and especially apartment buildings were heated with coal or oil-fired boilers and hot water running through pipes in the walls, connected to metal radiators in each room. (If air bubbles became trapped in the hot water pipes, it could cause all kinds of bangs, rattles and noises, which could echo throughout the building!) In modern times, many houses are heated by natural gas, with hot air being forced through metal ducts in the attic. Since it is also easy to connect your air cooling mechanism to this, it is often referred to as "central heating and air conditioning".
Why does heated air arise?
Cause its lighter than room temperature air..
My fireplace is losing too much heat up the chimney. Is there a way to delfect it?
You ARE going to lose heat up the chimney. Couple of things you can do to keep SOME of it in the room. Got a set of doors for the fireplace? They need to be open while burning, but can be closed as fire goes out, keep from sucking warm air out of the room. There are heat exchangers that are metal tubes with a fan. Tubes heated by the fire, fan pushes air thru the tubes, out into the room. The "Heatilator" style fireplaces have a heat exchanger built in to the fireplace. The heat exchangers are not cheap, and are still not as efficient as a wood stove.
Why does a room with a gas fire need to be ventilated?
First warm/hot air is lighter than cool/cold air. As the fire in the fireplace consumes oxygen from the surrounding air, it is also heating this air. This heated air then rises, and as it rises cooler air is drawn in from the surrounding room. As long as the air in the fireplace is warmer than the air in the room, this process will continue..
Why does the gas log fireplace not heat a room?
It's most likely a woodburning/vented fireplace, by design the combustion air used to burn gas logs comes directly from the room, and all the fumes/hot air go up the chimney. The fireplace actually pulls outside air into the home to replace the air lost up the chimney. All the heat is radient, so if nothing is there the feel the heat, it is lost.
Did the Benjamin Franklin stove have a Benjamin Franklin statue on it?
The "Franklin stove" (not "Benjamin Franklin stove") was named after its inventor, Benjamin Franklin, who would never have thought of putting a statue of himself on it. The Franklin stove is actually a metal fireplace liner that allowed a fire in the fireplace to heat a room more efficiently. It contained a hollow "baffle", a wide, thin iron box near (but not at) the rear. The baffle was open at the bottom and contained two holes on the sides. Heat from the fire rose on both the back and front of the baffle, so that air entering at the bottom of the box was more quickly heated. Heated air rises, but instead of escaping out the top of the chimney to no purpose, in the Franklin stove, the heated air exited into the room through the holes in the baffle's sides.
Is holmium explosive?
No, Holmium is stable in dry air at room temperature but is rapidly oxidized in moist air or when heated.
