Pellet Stove Chimney And Proper Wood Pellet Stove and Boiler Venting

How you vent the exhaust gases of your pellet stove and you pellet stove chimney is often an overlook area of purchasing a pellet stove. However the type of chimney and its location can effect fire safety and also the efficiency of your pellet stove. In terms of fire safety, the type of construction materials the chimney is passing through is very important. Some materials can ignite with some pellet stove chimneys due to the high surface temperature. Therefore the location of the pellet stove and its chimney are very important. The risk can be removed by choosing more advanced chimneys. A modern chimney cannot only reduce fire risk, it can also increased combustion efficiency and reduce smoke, particulate emissions and creosote build up. A traditional chimney will be single walled. This means the outside surface of the chimney is very hot, therefore traditional single walled chimneys are responsible for fire risk concerns.

Wood Pellet Stove Double Walled Chimneys and Direct Vent Chimneys

More modern alternatives to the single walled chimney, are the double wall and direct vent. The double wall has a layer of foam insulation between the two stainless steel walls. The advantages to this are the external temperature of the chimney is dramatically reduced. The other advantage is that the exhaust gases are kept at higher temperatures as they pass through the chimney. If exhaust gases cool too much, they can cause creosote to condense on the inside of the chimney. Eventually this will lead to a restriction in exhaust gases leaving the pellet stove. This will ultimately lead to the pellet stove choking its self, resulting in poor combustion, increased fuel consumption and even smoke being pushed back into the living space. A direct vent chimney works on the principle of using the waste heat of exhaust gases to pre-warm combustion air. The combustion air is brought from outside along the outer edge of the hot chimney. Warming combustion air, means increased combustion efficiency. This has several benefits including generating more heat from less fuel, and less ash.

Choosing The Best Wood Pellet Stove and Best Wood Pellet Boiler

Several factors can be used to choose between one make and model of pellet stove, including the type of chimney the stove is designed to work with. Another important factor, it what type and grade of wood pellets and other biomass pellets the stove can use. Up until now, the only other type of fuel people were aware of to be used in the stoves were corn. However as corn is a food, the prices of corn are quite high, there are also the implications of using a food for a fuel source. However there are other possibilities, such as corn stalks can be processed into fuel pellets, and corn stalks are currently regarded as a waste.

The key issue is many pellet stoves cannot burn pellets such as corn stalk pellets. Even though these types of pellets generate the same heat as wood pellets, they also generate more ash. However the increased ash also comes with the benefit of a much cheaper fuel. Please click the link below to download.
