Go Greener Tips

Venting the pellet stove is obviously a crucial component of the installation process. The location of the vent on the property is also important. To diminish fire risk and for general safety certain criteria have to be met. These will depend mainly on the wall material the vent will exit through. If you need any extra assistance other than manufacture guidelines, your local fire authority should be able to help. There are quite a lot of different designs of pellet stove vent obtainable on the market. Some of the vent designs can even improve incineration efficiency, this will lead to more heat, less fuel consumption as well as less smoke and ash.
The three main types of vents obtainable on the market today are a single wall, double wall and direct vent. There are fee differences between these different types of vent, by means of single wall the cheapest, then double wall and direct vent.

Pellet stoves are a more advanced form of solid fuel heating compared to log stoves. Most log stoves used the basic single wall vent, yet most pellet stoves today use the double wall or direct vent. A double wall or direct vent can increase combustion efficiency and also decrease issues such as creosote build up. A double wall vent has a layer of insulation between the two walls. The insulation has two benefits, it acts a safety feature and can also decrease fire risk with reducing the outside temperature of the vent. The insulation can also diminish creosote build up by way of keeping the exhaust gases hot.
A direct vent further increases combustion efficiency by means of heating up the incineration air. Efficient incineration is based on a energy by a low moisture content and high combustion temperatures. A direct vent passes the burning air down the outside of the exhaust gases. This effect means the combustion air is warmer producing higher combustion temperatures.

As a direct vent impacts directly on the source of burning air for the pellet stove, a stove which has not been designed by means of a direct vent cannot easily be retrofitted with one. There are also other features and designs on pellet stoves which effect combustion efficiency as well as fuel flexibility. A few examples include the design of the burn pot as well as pellet auger feed system. The designs of these features can impact directly on the ability of the stove to burn dissimilar grades plus brands of biomass pellets effectively. Some pellet stove designs are so intolerable to changes in ash, that complications can arise from changes from one brand of premium biomass pellet fuel to the next, or batch to batch.
