What are you using for your substrate? How deep is it? Have you measured the temp under the substrate? My guess is that your UTH is working fine. A IR temp gun is perfect for quickly measuring surface temps. UTH's are good for belly temp, but not great at raising ambient temps. I have learned a ton going through exactly what you are going through now so keep the questions coming...you will find tons of help here.
