What is a fireplace insert?
From Wikipedia, the free encyclopedia
Answer: Invented in 1869 by Joab R. Donaldson of Oliphant Furnace, Pennsylvania, USA, the fireplace insert is a device inserted into an existing masonry or prefabricated wood fireplace. Joab was a 59-year-old coal miner and father of fourteen at the time of his patent. He came upon the idea as a means of using coke (a fine particle sized coal) and incorporating the use of an electric blower to improve the efficiency. The selection of coke and coal tailings as a primary fuel enabled low income families to heat their Appalachian homes with small-size coal that they could easily dig for themselves in their own back yards.
Fireplace inserts are these days categorized primarily by the type of fuel used (natural gas, propane, EPA-certified wood, pellet and coal), though most people associate them with burning wood.
Fireplace inserts are invariably made from cast iron or steel and most have self-cleaning glass doors that allow the flames of the fire to be viewed while the insulated doors remain closed, making the fire more efficient. This makes use of an “air wash” system whereby clean air is directed across the interior surface of the glass and thus prevents the build up of deposits.
Today, many manufacturers also augment the operation of fireplace inserts by offering features such as fans and thermostatic controls, depending on the fuel type. Typically fresh air enters through vents below, circulates around the main chamber, where it is heated up, and the warmed air then exits through vents on the top of the unit.
Fireplace inserts are popular with people who have an existing open fireplace and chimney, since they significantly improve both fuel efficiency and heat output while also providing an attractive focal point to a room. The disadvantages when compared to a free standing wood burning stove are that they are more expensive to install and obviously also depend upon there being a usable fireplace and chimney in the first place.
