Animal Plastics CB70 rack heating question

[Artemille]

I don't have any tubs yet but have been researching my options and from what I understand you should cover 30-50% of the floor space with you heat source. So I think 3" is tad small lol. Also your hot spot should be around 90, with your current room temps the 80 cool side should be achieved. I would say at least 6inch tape. But I'm no expert.

Yes, I would have it on a thermostat to keep the hotspot at 90, but I'm mostly wondering if the heat would raise the rest of the tub 3-5 degrees.
