Does it need to touch the pipe? What kind of mounting options does it have? Can it detect a freeze if the freeze does not affect ambient room temp?

So this is better to place in the water pan under the water heater or heat pump, and it only detects ambient temperature. The moisture pins are under the system and would have to lay facing the ground only no mounting.

It has two contacts on the bottom to detect moisture. I just have mine on a floor near my water heater.

On the back of the sensor, there are 2 sensors or contact points. When water touches the 2 points it completes the circuit. It is designed to sit in a drip pan of some sort. You would have to make your own mounts. I believe it senses ambient temp.

Gasper G. was right on the money! But, it is important to protect the unit from the wind. We have seen a number of outdoor units this winter (in NC) freeze because of the wind chill effect. Make sure exhaust vent is clear and a wind block set up around the unit. Hope this helps!:)

You can set it as low as you like; there is a feature that lets you set a minimum (40F by default, to keep the pipes from freezing) but you can turn it off.

That depends on a number of variables. It will keep a 4" pipe from freezing if it is not exposed and it isn't extremely cold. It will keep it warm enough if it is 0 or warmer. Smaller pipes are actually more prone to freezing than larger ones. The best way to ensure it won't freeze is to keep the water in the line moving.

yes it has a few ways of mounting, a U bracket for a pipe and a square plate with appropriate screws. I use it for indoors because I want to figure out (after the snow0 how to mount it with as little bird exposure as possible :)

Unfortunately I don't think this will work for you. I have had mine freeze up when it is only down to 0°F. so I think you'd have real problems at -40. There is not much insulation in there, so it might work if you sprayed more insulation inside and maybe put a gasket between the fixture and the ground and maybe another gasket on the access door on the side. I don't know if there are other waterers that would work any better. It is also critical that the waterline feeding the waterer does not freeze up below grade as it passes through the frost line. I had this occur to me one time and used halogen lamps to heat up the ground. Unfortunately I don't think this will work for you.

Yes, you do not need to touch a connection the probe can detect up to several feet away. You can get false positives with air flow so follow directions and you should be fine. I used the probe to find a LP leak after two HVAC guys failed to find it. It was in an air return where a piece of flex pipe was routed and had a pin whole leak. I keep getting weak readings around the duct opened it up and inserted the probe and wow, it was a hot spot, actual flex pipe was about 5 ft away.

I used it as such recently when we had those sub zero degree days. Keep in mind that it does not get SUPER hot, so though it wont melt right through the plastic, if left on for a long period of time (days/weeks), it can destroy the integrity of the plastic and possibly make it "droopy" or bend slightly as the cable has some weight to it. I'd say , fom experiance, if such a pipe is freezing and/or frozen, using it to thaw the pipe should cause no issues. I'll check the installation guide that came with it and if it happens to say different, I will repost. FYI : it works great on standard copper piping and such.

I covered it with pipe insulation from Lowes - taped with electrical tape and works great - below 10 degrees did not freeze

Sensors are attached to outside of pipe with stainless clamps or Ty wraps. One is the turn on sensor other is turn offHad my for a year works great!

Well, ordinarily, we don't think of Oregon (at least in the Willamette Valley) as a cold weather state. But it got collllllld here this winter for a few weeks. I have pipes that run along the side of my house from my exterior mounted Rheem and those I wrap with an electric heat tape which only goes on if it gets to about 33degrees. The heater itself is protected internally by small heaters which are attached in various places and do a good job. That leaves the inlet and outlet array (which includes the valves and TP valve) which the heat tapes are hard to attach to. So I leave a small amount of water running at night and during the day when no one turns on a tap for an hour or so. Somewhere between a drip and a stream. That seems to do the trick. This summer I am going to put the pipes inside the wall and put the heater in an inclosure that you can buy from Rheem that fits into the wall, and my hope is that I will not need any more protection.

It doesn't give a temperature reading only says freezing or not. Detects moisture well. I have it set up with Smartthings to text me if my pump fails.

Mine is installed on a back wall of the house, in a semi sheltered alcove. It is not usually very cold in Columbus, GA and we have had no problems with it. I would hope there is a setting that would cause it to run a little to keep it from freezing.?? My wife lets the hot water drip just a little anytime that we expect sub 32 degree weather. Bob Behar

The black button has the thermostat inside. Position the black button flat against the pipe and wrap insulation around it as the instructions show. Good luck.

The Envi works by reflecting heat on the wall it is hung on. The wall ABOVE the envi gets fairly hot! That hot wall is what heats the room... more so than the heat escaping from the Envi. I've located my Envi about a foot above a hot water baseboard that I was concerned about. I'm not running that hot water baseboard much, so I've been afraid the pipes would freeze. That's why I installed the Envi! So far, in my application of a far bigger room, and installing the Envi on an OUTSIDE wall, I haven't frozen any pipes. Tomorrow? We'll see! If you use yours differently, and don't leave it on, your mileage could vary as well! There are few guarantees in life!

Yes. I have it hooked up under foam tube insulation. Keeps my water hose from freezing in the winter. Doesn't really get hot, just slightly above freezing.

My sensor is in my house so it's never exposed to "very cold weather." But our outside winter temps get into the 20's and teens at night and this has never set it off. But I keep the temps inside around 68 degrees.
