I received an email about climate control at Parkville High School the other day. The custodian of the building wrote a letter to staff on one of the warmer days this spring trying to explain why it was that heat was coming out of some of the units. The custodian said that he must fire up at least one boiler every day so that the school will have hot water for the kitchen. The custodian told the staff that the heating system wasn't always connected to the water heater, but ever since the water heater went up a couple years ago, they are stuck with current problem. So until school is out, a little bit of heat will be coming into classrooms, which of course, aren't air-conditioned.
