What’s a Corn Stove?

Corn stoves burn husked corn for fuel, which is renewable, efficient, and can be one of the cheapest fuel sources available. They can also accept multiple fuel types and are low maintenance. Corn generates constant heat due to stored ethanol and reduces the risk of fires. Companies make inserts or accessories for corn stoves, allowing for an existing stove to be retrofitted.

A corn stove is a stove that burns husked corn for fuel, relying on the natural energy supply in the dried corn to generate heat. Corn burns very efficiently and cleanly in a well-maintained stove and can be one of the cheapest fuel sources available. Corn stoves can also be designed to accept multiple fuel types, including pellets, grain, and other renewable fuels, to make them more versatile. Consumers can find them through stove dealers and manufacturers.

The corn stove includes a hopper to store a fuel reserve, a vent to allow combustion byproducts out, and another vent to draw in air to aid in the burning of the corn. Many can rely on outside air for combustion, limiting the drying out of the inside air, a common problem with wood-burning stoves in winter. In some cases, the hopper can store enough fuel for several days, and the stove tends to be very low maintenance, allowing users to fill it up and leave it until the hopper starts to run out.

As a fuel source, corn pellets are renewable as well as efficient. It takes only months to grow corn, as opposed to years or decades for wood and centuries for fuels such as natural gas to form underground. This may make it attractive to households whose goal is to increase fuel renewability and fuel efficiency. Corn generates constant heat due to stored ethanol, and the efficiency can vary depending on which variety a household uses to fuel the stove.

Chimney cleaning and similar maintenance tasks are greatly reduced with a corn stove due to the increased efficiency. This limits the risk of fires, a common concern with fuels such as wood, which create creosote buildups that can lead to wildfires. The stove is also usually very easy to use, igniting quickly to generate heat. The heat exchangers on the surface of the stove, as well as the dimensions, determine how much area it can comfortably and safely heat.

Some companies make inserts or accessories for corn stoves, allowing for an existing stove to be retrofitted. Consumers don’t have to install a new stove and ventilation system, simply by fitting a modular unit into an existing installation. In new construction or where you want to install a brand new stove, you can install a brand new corn stove instead of an insert.
