Will it burn out if left empty?

No it would be fine, but hopefully you won't leave your pets without water!

no.... it is a low heat to keep water from freezing....but will merely heat the air...and would not get too hot for the animals tongue on the empty surface..... i have one and do check constantly for filling as there will be evaporation in warmer atmospheres.

Yes. It depends on how long it is on. It is not burning hot on low but it is still hot but not enought that your gonna get burn.

Yes, it seems to go dormant when not in use. Takes one AA battery. Minimal power.

No. It has a minimum level shutoff to keep the machine operating safely. While I am not sure of that exact level, ( I'm guessing around 1/4 full) you run the risk of burning the machine out unnecessarily. We always run it full. BTW, once you heat it, it will reheat

It will wear down the battery if left in all the time. Wenleave ours plugged in while traveling, and unplug it overnight. It stays cold.

I have not left it on if I am gone, however the heat element does turn on and off automatically according to whatthe thermostat is set for. I think you would probably be ok.

Yes. I leave it plugged in all day and night. The heat isn't triggered until there is weight on the mat (their weight). When there isn't weight, the heat doesn't kick in.

I was thinking to do the same thing but I haven't done it yet. You can try and if you feel that it suffers and start overheating that it s not good to continue because it may burned out.

I'm not sure...I don't leave it on when it's not in use. I only turn it on when I go to back up my files and then I power down after I'm done/eject.

yes, the bottom should empty completely. As soon as you hear it start to gurgle, it's done! be careful it is hot!

You'll end up with an empty part. My wife and I use it all the time and when we don't fill it all the way it's not an annoyance.

Yah it will shut off of left unattended for long periods. Not sure of the exact cutoff time period

Not sure what you mean by "burn out", but if I overfill it the only thing that happens is maybe the water runs out. It still works. I just dry up the water and pour a little out. +

Yes, I leave mine plugged in all the time. It stays quite cool when not use.

No, the way I understand it... it won't cook the battery or drain it during the night. I've left one on for several months at a time.

I've run my previous one for twelve hours or longer. However, I burnt it out when I let it run dry overnight. I'm sure it would have continued to run, had there been water to pump. The unit is so good, for so little money, I bought another.
