Wood burning systems must operate under a variety of conditions during each heating season, and these different conditions create the need for a number of maintenance tasks. Chimney cleaning is usually needed more often in the spring and fall. On the other hand, wood burning appliances operate closer to their maximum heat output during the coldest winter months, creating stress on internal components. Many of the modern wood heaters have internal components that can wear out because of their exposure to high temperatures. These components can be replaced.
One of the best ways to ensure that your wood heating system gets the maintenance it needs to be safe and effective is to hire a fully-trained professional chimney sweep. A professional sweep will clean the system top to bottom and report any problems to you. The sweep might suggest that it is time to replace the flue pipes, catalytic combustor, or door gasket and will probably be able to do the work for you when the time comes. Your wood heating retailer may also offer sweeping and maintenance services.
