Briefly speaking, single stage system means there is only one level output in your furnace. For example, single stage heating system means your heating system has only one level of heating output, either gas furnace or electric furnace. Based on the comprehension of single stage system, it is easy to understand what the multi-stage system is. Multi-stage system means there are two or more level heating outputs in your heating system. The example would be the two stage system which means there are 2 level heating outputs. Except for the furnace, maybe there is another heating method such as floor heating. The second level output usually is treated as an emergency setting, if you want the room temperature reach to the set-point faster, than you can turn on the second level output in the two stage system.
