On the other hand, pellets are made from compacted, sawdust, wood chips, bark, agricultural crop waste, waste paper and other organic materials.
Other pros Thew has found with the pellet stoves is they are able to be thermostatically controlled and will start and shut themselves off.
However, there are other things to take into consideration if look at pellet stoves.
Thew said the pellets come in 40-pound bags that will need to be lifted and poured into a small container in the stove.
"That may become an issue with a particular customer," he said, adding the pellets typically need to be filled on a daily basis.
Another issue is the cleaning of the stoves.
"Those customers that don't want to spend a lot of time cleaning them, because you do have to clean any solid fuel burner," he said.
Also, if the power goes out, a pellet stove will be useless.
"With pellet stoves, unless you have a battery backup system, or a generator, when the power goes out, you don't have heat," said Thew. "Those are just things we look at when we talk to a customer."
