Get the fireplace ready for Fall and Winter

Get the fireplace ready for Fall and Winter

Cool Fall weather approaches, and soon a cozy fire in the fireplace will be enjoyed by many. Fireplaces need annual maintenance, and while Spring is the best time for sweeping chimneys to remove smelly creosote, most homeowners wait until cool weather hits to have the chimney inspected. Chimney sweeps call Fall the “insane season” for this reason.

The National Fire Protection Association recommends annual inspection by a professional chimney sweep and sweeping as necessary to remove flammable creosote. Creosote is the natural by-product of combustion and occurs even when dry hardwoods are used. It needs to be removed on a regular basis in order to avoid chimney fires, which can cause thousands of dollars in damages.

A chimney sweep should do a visual and internal camera inspection of the flue and smoke chamber, and all components of the fireplace and chimney, and provide a written report of his/her findings. If repair is necessary, the sweep should explain the problem and offer repair solutions. If he does not do repair work he should refer the homeowner to a qualified chimney contractor.

Many chimneys have been affected by the summer drought conditions. Dry ground retracts from chimney footings, and can cause the structure to lean. If a chimney leans far enough, the only solution is to have it torn down and rebuilt. This should be checked by a specialty chimney contractor, rather than a chimney sweep who only sweeps chimneys.

Wood stoves should be swept and inspected at least twice during the burning season. Creosote accumulates on the interior of small chimney pipe and can cause drafting and performance problems.

If sudden smoking occurs while burning a fire, this can be a sign that a chimney fire has occurred. During a chimney fire, creosote expands outward and may cut off draft, which can cause smoking. If a chimney fire is suspected, the homeowner should call a professional CSIA Certified Chimney Sweep to inspect it before using the fireplace or wood stove again.

Check list for Fall fireplace preparation:
  • Be sure that glass doors or a screen is installed to keep sparks at bay. Rusted screens can be replaced. A good set of glass doors with a seal help to keep cold drafts out of the house when the fireplace is not in use.
  • A top-sealing damper provides better protection from drafts and keeps insects and bats out of the flue since it creates an almost air-tight seal at the top of the flue.
  • Be sure to have a good quality heavy duty stainless steel chimney cover installed on all flues to keep damaging birds, animals, and rain out of the flues.
  • Obtain a good set of fireplace tools that will last for years.
  • Keep combustible materials and wood at least 36” away from the fireplace opening.
  • Have the chimney and fireplace inspected and swept by a professional chimney sweep. If in doubt, don't use the fireplace until it is inspected. Make sure the sweep uses an internal camera system for the inspection. He/she will advise you whether the chimney is in suitable working condition or not. 

  • Have masonry repairs made before cold weather sets in. Cracks or missing mortar joints on exterior chimneys or in cement crowns allow damaging rain to enter the interior chimney.
  • If the flue, smoke chamber, or fireplace is damaged and needs to be relined, do not use it until this work is completed.

Wood Stove Decathalon to prove efficiency

November 18, 2013

Competitors are finishing up the first ever Wood Stove Decathlon at the National Mall, 12th and Jefferson Drive SW in Washington, DC.  The Decathlon, held November 15 - 19 challenged teams to design and build wood stoves that are highly efficient, produce low emissions, and are innovative and affordable.

The event is sponsored by the Alliance for Green Heat, the U.S. Forest Service, the New York State Energy Research and Development Authority, and industry groups seeking to improve the efficiency of wood-burning appliances.

The 14 finalists are Dragon Heater, Firemaster, Helbro Stoves, HWAM, Intercontinental, Kimberly, Mulciber, Ofenbou and Feurerstellen, Smartsove, Travis, Tulikivi, Walker Stoves, Wittus, and Woodstock Soapstone.   These companies entered high-efficiency wood stoves, hybridt stove/rocket heaters, and masonry heaters, as well as retrofits to modify existing wood stoves to improve efficiency.

According to Dragon Heater their Helix stove is a hybrid of traditional wood stoves and rocket heaters. It utilizes a traditional firebox with horizontal feeding of the wood including a glass door for viewing the fire. Then, it uses the turbulence and an internal stack or secondary burn chamber from rocket heaters to produce very hot, optimized burns.

Jason Stewart invented the IntensiFire, which is a new downdraft retrofit for wood stoves. He said that  Downdraft brings the benefit of more complete combustion up to 60% more for the same amount of wood. It will bring the benefits of secondary combustion air to older stoves that don't have this function. Baffles are no longer required and the cost of the IntensiFire is around the same as the cost of a replacement baffle.

A team from the University of Maryland created the Mulciber Wood Stove, which includes heat recovery and smart ventilation and burning systems.  It has automatic systems to control air flow in order to maintain the ideal burning conditions and thermoelectric generators provide power to circulate stove heat throughout the home.

Tulikivi introduced their Hiisi 4 hybrid heat-retaining fireplace using soapstone which releases heat more slowly.  The Hiisi 4 uses cord wood or pellets without electricity to operate, and is designed to meet the world's tightest emissions standards set for 2015.

The winner of the contest will be announced on November 19, 2013.
