At what lowest temperature will the water stay liquid and not freeze? It gets below 0 degrees Fahrenheit here, &amp; not sure 30 watts will work.

Since water freezes at 32, I can't see that being an issue. Now if you meant Celsius, that's 93F, so once again, I don't see why it wouldn't work.

I wondered the same thing, so I experimented with it. (I have two, actually). In a room that was about 42 degrees, they heated the water to about 52 degrees. I have to wonder why they're heating the water when it's not even close to freezing. A waste of electricity. I guess I have to go back to unplugging them when it's above freezing outside.I also tried it at room temperature, and they did not heat the water. So the thermostat does work, but not at the target temperature that you would expect (at or just above 32 degrees).

I would add to the previous comment two points: Water boils at different temperatures depending upon one's elevation; I'm at 1380-1385 feet or so, and if I recall properly my water boils closer to 205*F than 212; so look up your elevation and factor in the correction. With regard to chips of ice and water, the temp will be a little higher than freezing, given the water is obviously not frozen; when I calibrate my thermometer probes for testing produce I look for a reading closer to 33*F, or 34*F, when left sitting in a glass of ice water; clearly the more surface area of the ice chips the better, and allow a few minutes for the temp to stabilize.

it only turns on under 32degrees but as to the lowest outside air temp it will keep the water from freezing I don't know. We keep it in the chicken house, central NJ and I have never seen the water in the bowl or the tank freeze. I think the chickens would freeze first.

Tonight the low is 27. Will this switch turn on the aquarium heater I have in my pond when the temp drops to 35 and then turn it back on only when temperature in the air returns to 45? Why not just on and off at 35? Is his to provide an extra period of warmth to get well above freezing?

Water is still liquid at 35, so it will work just fine. My pump has not been out in freezing temps so far this year, but the literature says it has a thermal protection device to protect it. I will have to wait and see, but so far it works great.

It won't make water higher than 120. So &lt; 120 is a good attempt to answer your question. If you are pre heating with solar, you prob. are limited to around that temp.

i have it @ 7 Celsius , and is working fine so far. i think you can still go lower. hope this helps.

I can't say for sure but I imagine it can be set as low as you want. Of course, it's probably risky to set it lower than 50 in the winter as your water pipes might freeze and burst.

46F is the lowest setting. use it as lager beer fermenter so around 50F is sufficient for me.

With a 30 gallon, max "low" water level would be about 4-6 inches below the top rim before the pump starts sucking air and loses siphon. Keep in mind this will also make pump susceptible to losing siphon much faster as water evaporates. I'd recommend an internal power filter for any tank you want to keep water level lower than an inch or two from top rim.

How many gallons you are trying to keep from freezing over and I not sure what wattage you are looking at? I have 2 ponds (2500 and 3000 gals. between 3 & 4 ft. deep) I have the 1500 Watt and just to keep an area open I could have probably gone with the lowest wattage and still had an area that didn't freeze over. The depth of your pond will also determine how quickly it will freeze, the deeper the pond the better and the less wattage needed. I live In Canada just across the border from Buffalo, NY.

ABSOLUTELY. I live in Colorado and right now my incoming water is below that (sometimes in the 30's) and it works fine. Now, It will have a difficult time running 2 things like a shower and a sink at that temp but with 1.75gpm you will be set. I've had mine for about a year and love it. This is the 4th tankless water heater I've had and couldn't be happier, it works flawlessly.

I've used my Comark from around 60 degrees to temperatures around 350-360 (hot grease for fish). I've never used it to test below zero.

Hi Pat, I placed water in the pot and used a meat thermometer and checked the temperatures of this unit. I only recorded the one at #3 and it was 180F. I have found this does seem to cook on the Low setting closely. I have been very happy with the unit. I hope this one temperature is a help for you.

I don't know the lowest, I have never set it below 36 F. I use one in my shop to keep things from freezing.
