T-FAST Sizing & Selection

Project Information

please enter your project information

Ready
Sizing Method
Uses BS 8558:2015 Loading Unit data to calculate weighted DHW peak flow demand
Hot water outlets
T-FAST unit arrangement
Duty units share the calculated flow. Standby units are additional spare units of the same selected model.
Buffer vessel selection
Buffer volume is calculated from peak flow and load period, then matched to the Fiorini PFA vessel range.
ScaleStop selection
ScaleStop selection divides the calculated total mains water flow by the number of ScaleStop units.
