Is it okay to keep the top of the heater out of the water in order to allow the changing of the temp setting controls or does it have to be submerged?

Yes, there is an indicator line on the heater itself that shows the minimum water level.

My heater is placed so that the temperature control button sits above the water. It has worked just find for about 10 months!

Yes it must remain plugged in, otherwise the heating element will cool and not produce steam. You cannot control the amount of steam...as the water runs out, it will stop producing steam. Once the steam is flowing it will not stop unless it runs out of water or turn it off.

Yes, it needs to be in the on position. If you are asking if there is a way to adjust the temperature (or speed of flow) without touching the handle, there is not. You can turn it on or off by waving at it, but the rate of water and the temperature will be whatever you set the handle to last.

Yes, just don't plug in the unit until it is completely submerged. If the heating unit is heated out of water, it will burn out.

no you have to hold it down. But you can turn the heat to low which is fairly cool to me.

The fact is it is supposed to be covered with water at all times. I did allow mine to get the top half uncovered and did not cause any damage. I would not recommend letting any part of it to not be submerged completely.

Your heater will kick on and off during warmer days and as water changes temps. White foam and bubbles are a normal issue with water temps changing..all is fine no worries

Talked to tech-support and they said yes, this unit will regulate the water temperature to the SET-temp. and ultimately shut off if incoming temp is already at or above the SET-temp. unrelated, I am experiencing fluctuations in the output temperature; (with stable input temperature) it may be bad sensors, so this still needs to be figured out

It's just supposed to keep a circle of non-frozen water around the heater. Only when the temp really drops (like 20 degrees F or lower) do I sometimes see some "foam/bubbles" right around the heater in the non-frozen water. Should not get "warm" as you say. What's nice is that this heater only works to thaw the ice when the weather says it needs to and shuts off when it's not needed.

No, but turning down the thermostat on your water heater would do that, as well as save you money on heating your water higher than you need it to be heated. Just search on the internet, "how to turn water heater temperature down"

The heater control is not intended to bea thermostat that will keep an area temperature no lower than a setting. It keeps the heater no colder than a setting so my heater came on briefly when the temperature was 25F. It didn't significantly heat the area. I would not trust this heater to keep an area from going below freezing, The outsidetemperature plays a major role in the temperature that this or similar heaters heat an area. By experement you could find a setting that would keep an area at 40F but if the outside temp. took a dive the inside temp will also go down but not as much.If you need to freeze protect an area plug your heater into a Farm Innovators TC-3.

It's controlled by a thermal switch normally open set at around 35 to 36 degrees, then turns off around 43 degrees. Is set to keep the water from freezing.I've taken it apart and had to replace the thermal switch on a few of them, they tend to go bad when they get wet. Stv

My experience is it must remain submerged. This heater has failed at this point for me anyway. So I would suggest another brand or style. Mine didn't last very long. I am now using an adjustable version. Aquatop GH150 Aquarium Submersible Glass Heater, 150-Watt. And it works great. Lets hope it last longer.

This has its own thermostat. If suppy water temperature higher than the target temperature than it will stay off. I don't know how well it maintain the targeted temperature. I think it is fine, because I don't hear any complain from my tenant both winter in NY (2014 & 2015).

There is a double wall on this heater. I was thinking like you where this is concerned. I had an older heater of this type that i could leave a pot of water on. The top of this one is only warm.

Water should never enter the bottom where the vents are. You should only clean the reservoir part and never submerge the entire base in water. It is electrical remember that

This is simply the heater element, temperature control is in the water heater's thermostat. There is no overheat protection within the element itself. (I tell you this from experience.)
