Spring classes start Tuesday at the University of Florida, but it feels like anything but spring outside. Besides some holiday gifts, most students are bringing back extra clothing to help with the cold weather outside, but they might need to keep those layers on inside.

Since early December the main heating system has been shut down for repairs--its supposed to be finished by Friday. Until then, all heating runs through two backup boilers. That wasn't a problem until now. With temperatures dropping below freezing the boilers can't manage the demand and heat isn't being distributed evenly.

"Because the backup system isn't quite as powerful as the regular system students, faculty, and staff may notice offices being a little chillier in certain parts of the campus," said university spokesperson Steve Orlando. "I know we've noticed it here in Tigert Hall."

UF officials said the cooler building temperatures is the only weather-related problem. Water pipes don't have to be wrapped and landscaping includes plants that are able to withstand the cold.
