The average steam system is about 30% efficient. Losses occur in the boiler room, distribution system, equipment, traps, and condensate return. Enclosed is a quick self test you can perform to identify opportunities for savings.


Pick out the best answer to each of the questions for your current operations and record the percentage value.
