The Kalona Elementary School has had a geo-thermal heating system for 5 years. Superintendent Mark Schneider says the system is working very well. He says a lot of people say the system will pay for itself within 5 years, but he says thats different for them because it was a retro fit and not a new installation. Schneider says the geo-thermal system does a very good job in heating and cooling the school and they can see the difference in the utility bill.
