I can't bump up the temp I can't stand the heat plus I go through $700 in oil a month now . I put the bulb on a few hours ago and the and the temps have come up warm side 85 and cool side 78 except oddly enough the Uth was sitting at 88 I bumped up the thermostat and I am now at 90 on the Uth. I think I am going to have to use the infrared in the cold months. Soon enough the warm weather will be here.
