A tankless water heater sizing calculator determines the required flow rate (GPM) and temperature rise to select the correctly sized unit. Flow rate is the sum of all simultaneous hot water uses; a shower (2.5 GPM) + dishwasher (1.0 GPM) requires a unit capable of 3.5 GPM at the required temperature rise.
