Pellet Stove Venting Decisions And Other Facts On Wood Pellet Stoves

Venting off the exhaust gases of a pellet stove is obviously a crucial part of the installation process. Firstly a suitable position must be found to position the stove and venting pipe. For example the construction material of the wall can be an issue with regards to fire risk. Manufactures usually provide clear guidelines on suitable and unsuitable locations to position the stove and venting pipe. however you local fire service should also have some available information.

There are several different venting solutions available for pellet stoves, some solutions are more expensive than others, however they do have various advantages from improving combustion efficiency, to reducing fuel consumption. The most basic venting solution is the single wall vent. These have been traditionally used on basic log stoves, however they are inefficient.

The Advantages of Double Wall and Direct Venting On The Pellet Stove

Single wall venting is the most basic form, however can have issues with creosote build up and increased fire risk due to external temperature of the pipe. Today single wall venting is not very common on pellet stoves, with most pellet stove manufactures opting for double wall or direct vent installations. Double wall venting has a layer of insulation between the two walls. The advantages of this insulation is to reduce external pipe temperatures to reduce fire risk and reduce creosote build up. By keeping the exhaust gases hot the creosote can not cool and condense inside the pipe. Eventually this would cause a build up which would affect daft, reduce combustion efficiency and potential send smoke back into the room.

Direct venting also has two walls, however the combustion air is carried on the outer layer. The exhaust gases heat the combustion air and increase combustion efficiency by feeding the wood pellet fire with warm air.

Other Pellet Stove Components Which Can Affect Combustion Results

Venting can effect combustion performance, however there are also other features which can also effect how well the stove can burn pellets. For example there is a wide selection of burn pot designs used in pellet stoves. However each design has its advantages and disadvantages performing under combustion results. Each design effects how efficiently the stove can remove ash, and other possible issues such as clinker formations. Other component designs such as the auger feed system can also create issues. Some designs of augers cannot handle a wide range of pellet sizes. The issue is pellet length is constantly changing and some pellet stoves simple block with some pellets.
