At Mr. Vent Free, we get asked a lot of questions about vent-free stoves. Check out these common questions and answers before buying.

Q: What are the differences between operating a vent-free stove and a wood-burning stove or pellet-burning stove?
A: A vent-free natural gas stove gets it fuel from the gas lines, so you never have to fill it up. Wood-burning stoves and pellet stoves need constant fueling and removal of ashes. Vent-free stoves start at the press of a button; wood burning stoves need to be banked and stoked, or a fresh fire must be lit. Pellet stoves need their hoppers filled often and require electricity to run the hopper.

Q: Can you cook on a vent-free stove?
A: You cannot cook on vent-free stoves because they do not get hot enough; on the other hand, this also reduces the risk of serious burns.

Q: Which type of stove is more efficient: a vent-free natural gas stove or a wood burning stove?
A: Vent-free gas stoves are 99% efficient, which is hard to beat. Old wood burning stoves made before 1990 are extremely inefficient (they usually have solid metal doors). The newer EPA-certified wood burning stoves have to be at least 80% efficient to possibly qualify for a biomass credit. In additionally to being less efficient at burning, wood burning stoves lose a significant amount of heat through their vent; vent-free stoves don’t have one.

Q: Can a vent-free stove heat the whole house?
A: No, vent-free stoves are designed to provide supplemental zone heating. This means you can turn down the thermostat in the house and use vent-free appliances to keep the heat where you need it.

Q: Where can a vent-free stove be installed?
A: Choosing where to install a vent-free stove is easy because no vent or chimney is needed. They need to sit on a solid surface, not a carpet. Some states restrict which rooms can have them. In general, most places you would want a vent-free stove can have one (such as the living room, dining room, and other common areas).

Q: How safe are vent-free stoves?
A: The safety of vent-free appliances is well-established. Natural gas leaks in the home are rare but are easily detected by odor. All vent-free natural gas appliances sold at Mr. Vent Free come with a device that shuts off the unit if the oxygen level gets low. Research has shown that vent-free appliances do not contribute significantly to indoor air pollution nor spike the humidity to dangerous levels.

Q: How powerful a stove do I need?
A: It is easy to calculate which stove to buy. You need to measure the volume of the zone where you are considering installing a vent-free stove. Multiply the length, width and height of the area by 3.4 to find out the BTU’s needed to heat that area. Each of our stoves offers a range of BTU’s.
