Tank finally done! Got some pics and advice.

That's exactly why I asked, it's winter here too. My landlord has the heat set to 65f overnight. The basement can drop as low as 64f but usually 66f and can rise to 70f or a bit more afternoon. The daily swing is why I have a UTH and pro products RHP on independent stats to control the heat. Even with my RHP on a stat when the temp drops overnight my cold side temps drop overnight but hot side is stable. You can't possibly be checking often enough to keep playing with the power adjustment to maintain constant temps. I'd suggest hooking them up to stats. I personally use ranco because I wanted a UL certified control. I'm an hvac mechanic so I wired a power bar into it. You can buy them prewired in the US if you're not comfortable doing the wiring yourself. Yes they make a click when they turn on and off. You're talking about a fraction of a second sound that isn't really that loud. They were made to maintain industrial hvac equipment and set up is easy and takes 30 seconds. My snake is in the living room so it's a non issue but even still it's not enough to disturb your sleep.

OP pointed out in the second sentence that he is currently awaiting the arrival of his thermostat.

I agree about the sound of the click on the thermostat, it's not even worth mentioning.
