The Process Heating Assessment and Survey Tool (PHAST) introduces methods to improve thermal efficiency of heating equipment. This tool helps industrial users in the United States survey process heating equipment that consumes fuel, steam, or electricity and identifies the most energy-intensive equipment. It can be used to perform a heat balance that identifies major areas of energy use under various operating conditions and test "what-if" scenarios for various options to reduce energy use.
