I would not over think it. Below is a link to the thread on my aimara where I have pics of the drip system I setup. You will see I paid a plumber to come in and install another line from main water line. He installed I guess a ball valve which I have then connect a plastic regulator. I do not have the water line open full, probably like 25% and then the regulator takes care of the rest. This is in an unfinished part of my basement/laundry room which I come to regularly. I will saw the plumber warned me against using one of those tools that pierces a pipe instead of doing it like this.
If I could do it again, I would seriously consider having the plumber do this on the outline of my water heater. While it put strain on my water heater and potentially reduces its life, my aquarium heaters definitely turn on more often now. Also, my biggest concern is that if my power ever goes out I will have cold water dripping into my tank with no heaters to heat it. Versus if I connected the drip to my water heater, when the power goes out my tank will always remain at a stable temperature.
