How Does a Gas Wall Furnace Work?

The majority of gas-powered wall furnaces and heaters will work by a process called convection. Convection works by heating the air in the front of objects and people, warming the room’s temperature while at the same time giving it a toasty feeling.

There are two main types of gas-powered wall heaters. The first gas heaters have one pipe that runs to the outside allowing the air to be bulled in to the unit which will then allow the gas to be burned. That same pipe will then expel any potentially harmful fumes into the outdoors at the same time. The other type of gas heater is the ventless heater; this heater works differently and instead heats the room by drawing air from the room itself.

In the 1980’s ventless gas heaters did not have oxygen depletion sensors; this made them potentially dangerous because there would be no warning if the oxygen level in the area got too low. Although the majority of gas heater last for only 20 years some are still around in older homes and should be replaced if found. Oxygen depletion without warning can lead to suffocation especially if there is no external source for air to come in.

Gas-powered heaters provide a large variety of advantages. Firstly they output a very even, stable heat while not giving any drafts, while an electric heater would have to work harder and require more power so the entire room can be heated. Another advantage over electric heater is that a gas heater will keep on working even the If the power has been cut. Gas heaters are also self contained and do not need a boiler to run.

Despite their advantages, the gas wall heater and gas wall furnace also have some disadvantages. The biggest disadvantage is they aren’t suited to heat an entire home. Most will only be able to heat the specific room where the heater has been mounted and some may not even be able to heat a large room. Another disadvantage is burning gas is potentially expensive and harmful for the environment.
