To heat your average sized room (Approx 4m x 5m or 13ft x 16ft) your gas fire will want a heat output of 4-5kW. This is pretty standard on most gas fires. If you're wanting to heat a large room, you might want to go for a gas fire with a larger heat output..
Beside this, what is the best heat output for a gas fire?
Flueless gas fires have a lower heat rating than other fires of 2.5kw (other gas fires can go up to 6kw), but as they're 100% efficient, all of the heat goes into the room.
Also, what uses more gas fireplace or central heating? Mythbusting: It's more efficient to heat one room with a gas fire than with central heating. Central heating is more efficient to run than a gas fire. So if you have adjustable radiators, it's better to turn the radiator temperature up in the room you're using, and down in the other rooms.
Beside above, do gas fires give off heat?
Most Decorative Gas Fires will quote a heat output of 3.5kw, this is around 50% of the input (6.9kw) and as such the appliance is around 50% efficient. This means 50% of the heat will disappear up the chimney.
