Is Your Fireplace Keeping You Warm and Cozy? Suggestions For Be

In his thesis on the principles of fireplace design released in1799, Count Rumford emphasized the importance of the size of the flue as compared to the size of the fireplace opening. He advised that the cross-sectional location of the flue ought to be about a tenth of the size of the opening. However, fireplaces had the tendency to be smaller after the mid 19th century. Modern flue liner producers favor a ratio of one to 7, and there are sizing charts published that provide details on present standards.

If your fire smokes or won't burn appropriately, see if opening a window improves matters. If it does, you need much better ventilation in the room. One option is to install a window vent, although this may cause a troublesome cross draft. A far more efficient kind of ventilation is either a single ducted vent set into the floor in front of the fireplace, or twin ducted vents set into the floor or external walls on each side of the chimney breast.

When wood and coal are burned, flammable gases, tarry substances, acids and dust are given off. However, due to the fact that domestic stoves are fairly inefficient, not all these substances are consumed. Instead, they rise up the chimney and some of them condense on the inside of the flue. Unburned carbon combines with these tars and acids, producing soot, which develops over a period of time, therefore decreasing the size of the flue. It is necessary to have regularly used chimney sweeps a minimum of twice a year, ideally before, during, and at the end of the heating season. The regional trade directory sites contain details on fully certified and appropriately insured sweeps. A soot filled flue is a fire hazard, because the unburned elements of the soot can fire up, causing a chimney fire which can reach high temperature levels and damage the chimney.

If a flue is too big, its size can be decreased to enhance its effectiveness by the fitting of a liner. A selection of methods and materials are made use of, consisting of flue liners made of flexible stainless steel, ceramic, lightweight concrete sections, or concrete that has been cast. Other methods of decreasing the size of the fireplace opening in order to enhance fire efficiency, is to raise the level of the hearth or to fit a baffle across the top of the opening. If raising the hearth level or adding a baffle is not useful or is unattractive, then it might be worth asking a fireplace expert whether fitting a metal smoke hood or canopy in the opening is the best option.Heating Repair Tucson Arizona\n
