With the rising trend in restoring to use these fireplaces that have been bricked or boarded up, it is critical that these restored fireplaces and chimneys are working efficiently. For wood or coal burning fires to burn well, a great supply of air is needed along with a chimney to expel the hot exhaust gases and smoke. Also the fuel should be held in a grate clear of the hearth floor enabling complete circulation of the air and waste ash to fall by means of, so as not to stifle the fire. If the chimney or flue is inadequate or the flow of air insufficient, the fire will not function successfully.

In his thesis on the ideas of fireplace style published in1799, Count Rumford emphasized the importance of the size of the flue compared with the size of the fireplace opening. He advised that the cross-sectional location of the flue really should be about a tenth of the size of the opening. Even so, fireplaces tended to be smaller sized immediately after the mid nineteenth century. Modern day flue liner producers favor a ratio of a single to seven, and there are sizing charts published that give facts of existing requirements.

If your fire smokes or wont burn appropriately, see if opening a window improves matters. If it does, you need greater ventilation in the space. One remedy is to set up a window vent, though this may possibly cause a troublesome cross draft. A a lot a lot more productive form 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 provided off. Nonetheless, simply because domestic stoves are relatively inefficient not all of these substances are consumed. As an alternative, 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 builds up more than a period of time as a result lowering the size of the flue. It is important to have frequently used chimneys swept at least twice a year, ideally just before, throughout and at the finish of the heating season and the regional trade directories include facts of totally qualified and suitably insured sweeps. A soot laden flue is a fire hazard, since the unburned elements of the soot can ignite, causing a chimney fire which can reach higher temperatures and damage the chimney.

If a flue is also significant, its size can be reduced to improve its effectiveness by the fitting of a liner. A variety of techniques and materials are employed, like flue liners created of versatile stainless steel, ceramic, lightweight concrete sections, or concrete cast in situ. Other ways of minimizing the fireplace opening in order to increase fire effectiveness is to raise the level of the hearth or to fit a baffle across the leading of the opening. If raising the hearth level or adding a baffle are not practical or unsightly then it may be worth asking a fireplace specialist regardless of whether fitting a metal smoke hood or canopy in the opening is the finest answer. chimney brush critique
