I checked the temps when I got home from work right now and the top of the warm hide read 90 again. She was outside of the hide though so I was able to get a reading on the inside and it gunned at 86, so not bad. Cool side gunned at 78. Do you guys think that temp difference between sides is an issue or is it fine? I would tend to think that if it's just the top of the warm hide that is hitting 90-91 but inside it is in the mid 80's, it should be ok. Regardless, it's a 10-14 degree difference between sides but I'm not sure how much variation is too much. I don't think I want to move the RHP because that would mean drilling more holes. Plus, I think it would have the opposite effect I would want in summer and the cool side would be too warm.
Malum, if you don't have an air gap on the heat tape on a tub, where are you putting the thermostat? Doesn't the thermostat iteself create or require an air gap? I am going to try messing with the heat tape this weekend though to see if I can get it tighter. Do you guys think it would be bad if I put tape on all 4 sides of the heat tape? The instructions didn't want any tape on any of the black parts. The white areas on the top and bottom are real thin so that's another reason why I didn't attempt it. I'm not sure how yet but maybe I can find something to wedge the thermostat in the slot and keep it from drooping down as well. I can also get some 1/4in wood afterwards if it still seems the heat tape is too loose. My dad had the 1/2in laying around in his garage so I cut it up and that's what I used since it was the very fair price of $Free.99, haha.
I did go with the Pro Products RHP. Bob recommended the PH-115 Pro Heat panel 60 watt so that's what I went with. Thermostat for the RHP is set to 79 (remember the thermostat is on the cool side), and the heat tape is set to 86.
