I have a hermit cab tank, can i used this for a tank that is not submerged in water?

I would NOT. It is meant to be in water, and I think it would get too hot without water to disperse the heat.

Could you use this to take the chill off in a atrium?

no, this must be completely under water and 150 watts is not going to have much impact on such a space.....better use 150 watt light bulb or more.

The included digital Thermometer did not include a battery. Does anyone know what # watch battery it requires?

Mine did come with the battery, and "works". How accurate it is remains to be seen. I just received and installed the thermometer and heater tonight, so I'll check in the morning and compare to another thermometer.

Digital Thermometer supplied with this heater is almost 3°F off. Is there a way to calibrate it?

Mine is 10 degrees off. I can not express how unhappy I am with this product. The dial on the top of the heater is nowhere near what the water temp is, and the digital thermometer they send with it is horrible. Two other sources say they are off by 10 degrees. Never again....
