If you are looking for a safe and efficient way of heating your home, then the direct vent gas stove is the perfect choice for almost every home, Vented gas stoves are perfect for those who have working chimneys, or who have tried ventless gas stoves and disliked the smell and heat. If you intend to purchase a gas stove, the vented model is the best choice.
Vented Over Ventless
There are a number of reasons why a ventless gas stove is disliked by many home owners. The first reason is that there can be a poor quality of air. While there are less emissions than with a vented stove, there are still carbon monoxide, water vapor, and nitrogen dioxide, all of which are very negative by-products. Ventless stoves are also notorious for their unattractive smell, which some compare to burning kerosene.
You will also not get mold or mildew with a direct vent gas stove. These can lead to severe reactions, particularly from those suffering from asthma or allergic sensitivity. Mold is encouraged by ventless stoves' production of moisture, which can also have a negative effect on the structure of the house.
Direct Vent Stoves
Direct vent gas stoves are connected to fresh air outlets, and draw their air from this source, which is particularly important if you have a new home, as gas stoves draw in oxygen, and can quickly deplete levels in an airtight house. In addition, the air duct access means that any fumes and moisture are quickly drawn outside.
The direct vent gas stone has a two-way pipe which both takes in air, and emits undesirable products into the outside. These require no power for operation, as the air is drawn in through heat, and hot air containing fumes and moisture pushed out as it rises up the pipe. They are permanently attached to the side of the building, as they require these pipes to function.
Direct vent gas stoves often have attractive gas logs at the bottom of the fireplace, which are given an authentic glow and flame effect by the air currents. This makes the gas stove appealing and inviting. In addition, they are also likely to help limit the amount of energy consumed within the home, so you can save on fuel while enjoying a natural-looking flame.
The disadvantages to these direct vent gas stoves include the likelihood of heat being lost as the air is drawn upwards, and the risk of carbon monoxide being released into the room. As the direct vent gas stove is directly attached to the outside, there may be an increased risk of draughts and cold air being drawn into the room. They are also immobile, being fixed to a certain position in the room, which may limit the temperature of the room, even when the stove is working to its full capacity. They also have unattractive pipe fittings which can sometimes overwhelm a small living room. Gas stoves also vary wildly in their fuel efficiency, ranging from between 70 and 80 percent for standard direct-vent gas stoves.
