When considering the purchase of a pellet stove, you will need to decide between a bottom fed pellet stove and a top fed pellet stove. There are some differences between the two, so it is a good idea to make sure you are educated about these differences in order to purchase the best stove for your needs. While there have been some safety concerns regarding bottom fed pellet stoves, it should be recognized that these stoves appear to be perfectly safe provided that additional safety measures have been taken with the design of the stove. The factors that should be considered when considering the purchase of a bottom fed pellet stove are safety, cleaning and fuel requirements.

Safety Considerations of Bottom-Fed Pellet Stoves 

One of the primary concerns regarding a bottom fed pellet stove is safety. A horizontal auger is used with a bottom fed pellet stove in order to transfer the fuel into the heating chamber. As a result, the ashes are forced into the ash pan that is situated below. A sealed pellet hopper may be utilized in order to ensure that there is no back flow of flames or air that might create a safety hazard.

Cleaning Considerations of Bottom-Fed Pellet Stoves

The ashes in a bottom fed pellet stove will generally need to be removed approximately once per week when you are using the pellet stove on a regular basis. The advantage to bottom fed pellet stoves is that clean-up is typically easier due to larger capacity ash drawers. This is one reason why many consumers choose bottom-fed pellet stoves over top-fed pellet stoves.

Fuel Requirements for Bottom-Fed Pellet Stoves

There is often a question regarding the type of pellets that should be used in a bottom fed pellet stove. While higher-quality, low-ash pellets are commonly used in top fed pellet stoves, they are not necessary in bottom-fed pellet stoves. The reason that higher-quality fuels are required in top fed systems is that there is a chance that the burn area in a top-fed system could become clogged with clinkers and ash. That is not the case with bottom-fed pellet stoves. This is because the clinkers and ash are pushed directly into the ash pan. Due to the fact that premium, high-quality pellets are not required, bottom-fed systems are typically much less expensive to operate than top fed systems.
