Looking for Advice on using an RHP

[BPGator]

Bob suggested a 50 watt panel which will span 2/3 of the length of my pvc enclosure (36x12x12) and mentioned that it would replace both UTHs. From reading this forum, it seems a UTH will still be needed under the hot side when a Hide is involved (which I would assume most BP owners would have). Does the RHP get mounted towards to the hot side to create the temp gradient?

With the RHP you shouldn't need the UTH. The RHP will radiate heat that will be absorbed by objects in your enclosure. The RHP will be mounted towards the hot side to get your gradient.

Where does the Tstat Probe go and how is it attached (i.e tape?) Is it easy to get the temps dialed in? I remember spending a considerable amount of time getting my UTH temps dialed when there was no time pressure because it was pre-snake.

Different people will have different answers for this. I personally put my probe on the cool side. I've found this creates smaller temperature fluctuations. I have a hole drilled in the back of the enclosure and the probe just dangles in. I have it secured on the outside so it cannot be pulled in our out of the enclosure.

Any suggestions on drilling holes into existing pvc enclosure? I'll need some screw holes as well as Tstat probe and RHP cord holes.

It's pretty easy to drill through PVC. Not sure what your mechanical ability is, but the hardest part will be mounting the RHP to the top of the enclosure. If you've got nothing on top, you'll be find to run a bolt through the RHP mounting locations inside of the enclosure and use a washer and nut on the outside to fasten it.

Also, still having the high humidity issues (90%) and I believe someone mentioned an RHP could potentially help w/ this.

One of the reasons your temperature is so high is because your ambient temperature is so low. Bringing the ambient up will reduce your humidity. The RHP will increase your ambient temperature, depending on the objects in your enclosure.
