This means that parts of the DP cant really be wrapped. Will the exposed portions become a place for all that heat being kept in the pipe to escape and become superheated? I am really, really concerned about this. I will try and get a pic up in a second.
I wouldn't worry. going catless is where you'll get most of the heat reduced. the wrap and coating are finite improvements. I would say getting a vented hood would be the most effective way to keep things cool under the hood
