Description: Embodiments of the present invention relate generally to systems and methods for heating buildings, and more specifically to pellet stove design and control.BACKGROUND A pellet stove is a type of biofuel stove that burns biomass in the form of pellets to generate heat. Pellet stoves can burn corn kernels, wood pellets, cherry pits, and other types of biomass solid fuel. Pellet stoves became popular duringthe oil shortages of the 1970s. Over time, pellet stoves have become more sophisticated, and more aesthetically pleasing. Most stoves are now quite attractive, and are often used in homes. Commercial models are available, which can heat largebuildings or generate electricity. However, current pellet stoves often generate high levels of noise due to noisy blowers and/or turbulent flow of blown air through pellet stove components. Current pellet stoves often feature limited user interfaces and limited automatedcontrols, which may lead to more work and less choice for the user in cleaning and maintenance operations, for example. Current pellet stoves can often be expensive or complicated to manufacture, they often run at a relatively low efficiency, and mayoften be unable to burn low grade fuel or one hundred percent corn fuel, for example. Therefore, there is a need in the art for improved pellet stove design and control.BRIEF SUMMARY Embodiments of the present invention relate generally to systems and methods for heating buildings, and more specifically to pellet stove design and control. A firepot assembly according to embodiments of the present invention includes acombustion enclosure for housing a solid fuel during combustion, which has a top opening to receive the solid fuel and a bottom opening through which the solid fuel (e.g. ash) may be released after combustion. Such a firepot assembly further includestwo rails over which slides a bottom plate between a closed position in which the bottom plate substantially covers the bottom opening of the firep
