Office Water Heaters
Spend $150 now and SAVE $48 each year... ROI = 32%
Water heating in an office can account for three to nine percent of the total energy load. At the US average for a ten person office, the total energy cost is $5,680 and at 6% of that, the average cost to heat water is $340 annually. On the low end, a ten person office could spend $170 per year or $510 on the high end. While the energy costs alone are modest, you pay for your water more than once. It costs to buy the water, to heat it (for hot water), and then to get rid of it (sewage charges).
