Corn Furnaces (Bio-Fuel) Reduce Heating Costs and are Good for the Enviornment Too

Recent rises in fuel prices have had most furnace owners—whether propane, natural gas, or oil models—seeing a substantial rise in their heating bills. These new financial headaches, coupled with increased environmental concerns over the gas emissions from traditional furnaces, have many clamoring for the development of new, safer, renewable energy sources. Odd as it may sound as first, corn furnaces are actually leading the way to achieving this goal.

Corn furnaces work by burning supplies of shelled corn, which is a renewable resource. Oil and gas, however, are limited, non-renewable resources. As time goes on and supplies of these much-sought-after fuels dwindle, costs will only continue to skyrocket. Many people who already struggle to afford monthly heating and electric bills may find themselves unable to heat their homes at all.

Using a corn furnace to heat a home is safe and simple. Most models require refilling only every ten or so days, so there is no need to constantly keep an eye on the machine. The only ongoing maintenance need is emptying the ash tray once a week. If the corn supply runs out, the furnace simply shuts off. Corn furnace owners report a light smell similar to that of a barbeque when their furnace is running, which is far more pleasant than oil odors emitted from oil furnaces. Most importantly, unlike traditional fuel-burning furnaces, there is no creosote buildup to cause a chimney fire.

Compared with oil and gas furnaces, corn furnaces certainly hold their own. One bushel of corn is the equivalent to about 3 gallons of fuel oil, with the average home requiring approximately 250 bushels per season. (Remember that most places do not need heat year-round.) Most corn furnaces have a AFUE rating of around 85%, which is well above the United States federal minimum of 78% and higher than many furnaces on the market today.

Another highlight of adopting a corn furnace is the chance to help financially-strained local farmers by creating a steady and reliable market demand for greater corn supplies. Many corn furnaces are designed to accommodate other bio-fuels like soybeans and wheat, which are also renewable resources that help keep small family farms up and running.

If you're interested in trying corn as a heating source, but not quite ready to give up your current model, you can always install a corn furnace as a supplementary heating source. This allows you to fully experience the power and reliability of bio-fuels, while easily being able to switch back to your old oil or gas furnace if you want to.
