Masonry Heaters are site-built appliances made with firebrick and other natural materials. Masonry Heaters provide even comfortable heat for the home using the renewable resource of wood for fuel. They are very efficient and produce low emissions, so masonry heaters are better for the environment than fireplaces or wood stoves. For more information about masonry heaters we recommend visiting www.chimkc.com or mha-net.org.
As difficult as it is to think about cold weather during the nice spring and summer months when the trees are green and the flowers are in full bloom, wood burners need to start prepping for fall now.
Since wood needs to be cut, split and stacked months in advance so that it dries out properly, now is the time to get that project completed, and get some exercise to boot. There are several types of log-splitters available that can make the job much easier. Prices range from $150 for a hand-operated splitter, to $3,000 for a professional gas splitter.
Wood should be stacked off the ground, away from the house, with a covering over the top but not on the sides-- so wind can blow through and dry the wood out. For the serious wood-burner, a wood shed with a permanent roof will offer years of protection from the elements. Wood should be kept away from the house because creepy crawlies like brown recluses like to hide in between the logs. Check wood with an inexpensive moisture meter to be sure it contains less than 20% moisture content before burning.
Any dry wood will do- but hardwood will burn for a longer time since it is denser than softwood. By using hardwood less time is involved in loading up the wood stove or fireplace insert, but softwoods will burn nicely. Stay away from dry pine and hedge, however, because they burn so hot and fast there is a greater risk of a chimney fire or damaging a wood stove or fireplace.
Another maintenance task that should be completed in the spring is chimney sweeping. The Midwest Chimney Safety Council suggests that a professional CSIA Certified chimney sweep do the job. Professional sweeps are trained to check things that the layperson may not be aware of such as proper chimney and connecting pipe installation, clearances to combustibles, wall and floor protection. If used for primary heating purposes, wood-burning stoves and insert flues or chimneys should be swept at least twice during the wood-burning season and once after to be sure that flammable creosote is removed.

All wood creates creosote- even dry hardwood, and removal is critical to avoid chimney fires. Chimney fires can not only damage chimneys and connecting pipes, but may escape into the home and cause a house fire.
Check exterior masonry chimneys in the spring for damaged, missing, or spalling bricks (brick faces popping off due to moisture penetration), missing or deteriorated mortar joints, bad flashing or gaps in the flashing, cracked or deteriorated cement crown, and missing or improper chimney covers. Apply masonry water repellant sealer on a dry, calm day to help slow down the deterioration process.
For a prefabricated chimney check the wood chase for wood rot, holes from woodpeckers or squirrels, rusted metal chase tops, and damaged chimney covers.
All of these chimney maintenance items are best addressed in the spring and summer before cold weather sets in and makes work more difficult and expensive.
