WHITEWATER, Wis. -- The University of Wisconsin-Whitewater said that there won't be any hot water or heat on campus until Sunday at the earliest.

A boiler exploded in the university's power plant on the north side of campus Wednesday afternoon, knocking out the heating system.

On Thursday, windows were boarded up at the building, and nearby Esker Dining Hall remained closed.

Students said they aren't happy about having only cold showers on campus.

"You remember the Polar Plunge? (My shower this morning) was something like that," said Ramzi Salameh, a UW-Whitewater student.

UW-Whitewater is advising students on campus to help conserve heat by keeping residence hall windows closed.
