As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
8. The average energy cost to operate an air compressor is approximately $0.10 per horse power per hour. 9. Compressed Air system leaks totaling the size of a 1/4 orifice, at 100 PSIG, running 24 hours a day will waste approximately $15,000 worth of electrical energy a year.10..
