this kind
the heat pad was on the left side really just to block the view and stop heat loss through the glass on that side. one has been running on the opposite side for about 6 months with no problems. 3 months ago I added one the left side and it has burnt out twice now. both are the 25 watt exo Terras on a herpstat 6. the probes are set up and set identical on each side. stays about 76 on the cool side and when the heat pad was working about 85 ambiently on the hot side and about 95 under the hot spot.
as I reread what I just typed I am imagining a RHP would be better for this situation. I assume pro products is the way to go?
I was surprised by your rec of ultra therm when I have heard so much about rbi equipment causing cookoffs or fires.
