All circulator pumps are typically sized based on the heat load and head loss (pressure drop) for a given zone. Knowing the heat load (in BTU's) for a given zone, allows to calculate the required circulator pump's flow rate in gallons per minute (GPM). For hot water hydronic or radiant heating applications, the following equation can be used:
