"Since we were building through the winter months and wanted to take advantage of the heat beneath us, we had the heating system up and running early on in the building process. It was during that time that we learned something very interesting. We found out we only needed about 104ºF water temperatures to heat the flooring completely in 7-9 minutes. In that short amount of time we could tell things were cranking along. And within about 15 minutes, the system was putting out incredible amounts of heat. Now, keep in mind that this was a completely open house during the winter. Snow and strong winds blowing through that site. But that heat was so warm and toasty, the crew never really noticed how cold it truly was. Very impressive indeed!"
