Your welcome. A temp gun (www.tempgun.com) is always a great investment. Keep that thermostat at such a temp so it's 89-92 on her belly in the tub (that's measured in the tub, not necessary on the thermostat).

Getting your ambient temps up/consistent may be another step, depending on the temperatures in your room. Many times those UTH don't do much for the ambient temps.
