The unit works but unless I leave it on all the time, which with electric rates would be expensive, the batroom doesn't stay warm. The floor gets warm but I think I should have had a larger roll. Not as energy efficient as I thought. Thanks Charlie Williams
Once the floor is warm, the system will only draw energy a third of the time. In a typical bathroom, 24/7 operation would cost about 56 cents per day (30 sq ft of heated space, 12 cents per kilowatt).
