sorry let me repost. the heat on the hot side suring the day with both the UTH and the heat lamp is from 82-88 depending on the room temp. when the heat lamp is off it reads about 68-75. i don't know why its not that hot because the UTH is new.
That seems very cool, given that a UTH usually gets well over 100 degrees if it isn't on a thermostat. Are you measuring temps with a digital thermometer, at floor level?
