A building owner has several leaking hot water faucets that waste a combined total of 50 gallons per day. The supply hot water temperature in the building is 130 °F and the mains water temperature is 50 °F. If the hot water is provided by a natural gas boiler with an efficiency of 85%, how much energy could be saved if the owner repairs the leaking faucets? a. 23,292 kBtu/year b. 12,184 kBtu/year c. 1,717 kBu /year d. 14,326 kBtu/year
