No heat from fire

    Hi there. I've given up on lighting the fire in my apartment as no heat seems to be coming off it really. You can hold your hand right up to it and it does nothing, even when it's burning really well whether it be briquettes or coal or stroggs or whatever. We are on the ground floor of a 2 storey old georgian building.
    I've read that fires can be grossly inefficient and can have a negative affect making it even colder by sucking in more cold air (or something).
    I'm just renting the place so I can't install a stove, I'm not paying for it anyway.
    Is there any way of making the fire more efficient? thanks.

    First of all I suggest you install a thermometer in the room just to see how long it takes for the room to heat up. However I'm guessing why your fire seems "cold" is less to do with the fire itself but the building. Do you have large windows? are they double glazed? Are there drafts? Yes open fires are inefficient but they will still heat up a room. The issue you're having here is cold air is somehow entering the room and the radiant heat of the fire can't keep up. Seal the windows with a silicone gun make them as air tight as possible. Another thing which may be an issue is that a lot of heat is being lost through the walls, with it being so cold outside the temperature differential could be up to 25C. A lot of energy is required to bring the walls up to this temp and maintain it especially with it being so cold outside.

    Theres not really a lot you can do unfortunately seeing you're renting.

    Fires do draw air into a room and pump it out the chimney as a hot gas. Leave a door slightly ajar rather than trying to seal all doors/windows. That way the air drawn into the room will be warmer internal air rather than having the fire trying to suck in air through gaps in around the windows.
