Minnesota was recently put to the test when it had one of the coldest winters on record.

St. John’s University in the town of Collegeville undertook a heating system retrofit just before the winter season.
“We were approached by our local wholesaler, Ferguson Enterprises, with the suggestion that we consider replacing the pumps in the Peter Engel Science Center with Grundfos MAGNA3 smart circulator pumps,” said David Schlumpberger, the campus HVAC tech. “I wasn’t aware of them before, but the existing pumps were nearing the end of their lives, so we decided — why don’t we do something more efficient?”
