By controlling the amount of air being sucked up the chimney, it helps cut down the loss of heat. Open fireplaces can lose over 80% or four fifths of the heat up the chimney to warm the crows!!! A fireplace door can reduce this heat loss substantially. It will reduce the directly radiated heat by a relatively small amount. But if the fire has a back boiler, the addition of the fire-front doors will substantially increase the heat going into the boiler and thus to the radiators. 2.
