The short answer is that there is no difference. Outdoor Air becomes Indoor Air. Most of us spend more time indoors than
out, so the quality of Indoor Air is just as important as Outdoor Air. Perhaps even more.
A lot of people don’t give much thought to Outdoor Air
Quality. We at Woodstock Soapstone think about it all of the time.
We have to. It’s part of our business. But we also think about
Indoor Air Quality. Many people use Indoor Air to satisfy the combustion
air for their wood stoves. In very tightly sealed houses, the amount of
Indoor Air available for a wood stove may be limited or reduced by the
tightness of the house (super insulated) or by negative house pressure.
Some houses are so tight that turning on the kitchen exhaust
fan can compromise performance of the wood stove. In other cases, wood stove performance can be enhanced by
cracking a window. In both cases,
house tightness/negative pressure affects stove performance. This is why every
stove we build has the option of an outside air adapter, and our new Absolute
Steel Hybrid has an Outside Air Adapter built-in.
More and more people have been installing outside air
adapters on their stoves. Some
States and local jurisdictions now require it. All mobile homes require a wood stove to have an outside air
adapter installed. Check your local laws if you are in doubt.
The outside air adapter on our new Absolute Steel stove is
unique in the wood stove industry for two reasons: 1) All of the air that goes into the stove (primary,
secondary, and catalyst air) has to go through this one opening, and 2) it is
virtually leak proof. If you
really want to protect the air to your stove from other air circulation in your
house, and more importantly the negative pressure in a tight house, this is the
best way to do it.
Our wood stoves are not only clean burning, our new Absolute
Steel stove is one of the best stoves ever made at maintaining clean inside air
as well as clean outside air. We
feel the Absolute Steel has the finest outside air adapter design in the
And, to make life easier for you, we build an outside air
adapter into each Absolute Steel stove we make. If you don’t need it now, you may need it later, and it will
be there for you.
