![]() Tricks Of The Trade: Energy Costs For Gas DryersTFM Columnist Jim Elledge estimates energy costs for commercial grade laundry operations.
By James C. Elledge, IFMA Fellow, CFM, FMA, RPA, RIAQM Q Do you have a quantification as to the costs associated to run a 170 pound Unimac gas dryer for a commercial grade laundry? A Under test load conditions (bath towels on a 25 minute dry cycle), the unit should consume 144,296 BTUs (or 1.44 Therms). There are variables (What part of the country are you in? What is the temperature? What are the humidity levels?) which would impact the drying time, installation, and maintenance of the dryer (lint filters emptied after every load, exhaust lines free of debris and unobstructed). Recommendations for reducing operating expenses are provided on Unimac’s Web Site. According to Unimac, energy is about 15% of the cost to operate your laundry, of which drying tumblers account for nearly 70% of all energy consumption in the laundry. Elledge, facility/office services manager for Dallas, TX-based Summit Alliance Companies, is the recipient of the Distinguished Author Award from the International Facility Management Association (IFMA), is an IFMA Fellow, and is a member of TFM’s Editorial Advisory Board.
