Bayfield County solar hot water system produces result at jail in Washburn, Wisconsin

Solar Hot Water Project

Solar Hot Water System Producing Results
Third quarter 2011 results from Bayfield County Jail’s solar hot water heater demonstrate continued savings. 
Coolant was pumped from the roof top panels to the hot water transfer tank 1440 hours during the first 9 months of 2011, averaging 5.3 hours per day.   Water hot enough to feed directly into the hot water heaters was pumped from the solar transfer tank to the heaters 1267 hours thus far in 2011 or an average of 4.7 hours per day.
Hot water system savings are currently approximately $350 a month.  The panels were installed in 2008 and have pumped over 4600 hours to date. Estimated payback on the system is nine years.
