Wood Burning Stoves With Direct Air

Wood burning stove with direct air or external air is a new generation stove which is most often seen in newer, well-insulated homes. Like its name suggests, it supplies air from the outdoors. Wood burning stove with direct air usually involves a hole in the wall which is connected to a duct that runs to the stove.

There are several reasons why wood burning stoves with direct air are getting increasingly popular. The first reason is that the traditional stoves draw the air from the inside. This happens because newly built houses are airtight and as a result, the stove absorbs oxygen from the room. The second reason is that external air reduces the chances of the stove smoking into the room. The third reason, wood burning stoves with direct air help preserve the warmth because the fire gets all the necessary oxygen from the outdoors.  

The Problem of New Home Building Practices 

House building is not the same as it used to be. Modern houses are almost hermetically sealed. On the one hand, this eliminate the cold air currents and increases energy efficiency but on the other, residents and the stove are fighting for the air. Wood burning stove with direct air eliminates the problem of the stove consuming the hot indoor air, while the supply of outside air to the stove ensures that the latter is operating safely and efficiently.  

The Many Options Available

Many wood burning stoves feature direct air or external air supply. They typically come with in-built external air 'box' which provides direct air feed into the stove. Some brands, however, sell external air 'box' separately. The same counts for the spigot that is attached to the air duct which in turn supplies external air to the stove. The spigot is normally at the back end of the stove near the bottom or beneath the stove so that the attachment is hidden from the view.  

Total Vs Partial Wood Burning Stoves With Direct Air

Wood burning stoves with direct air theoretically don't use internal air. However, not all manufacturers claim that their stoves take external air exclusively. Some divide their stoves into partial or total. Partial means that only a part of combustion air is taken from the outside. The other part obviously comes from the inside. Total means that 100% of the combustion air comes from the outside. It is worth noting, however, that no stove is entirely leak-free. Therefore, no stove with direct air uses external air exclusively. Obviously, those with total direct air supply use much, much less indoor air than stoves with partial external air supply.
