Does it need anything (other than water or electricity) or ready to go from the box?

It's ready to go from the box. If your water is too hard you might want to buy a filter, but it functions perfectly without it as well

It needs electricity. It runs a fan to rocket the heat out and to cool it off after shut down.

It's all ready to go, nothing to assemble, just give it a quick rinse and fill it up :)

Not required, even if hooked up to a generator instead of city/county power. My refrigerator and freezer work fine as well as some battery chargers I had running off the dirty output of a poorly regulating generator but the UPS kept flickering on and off so I had to unplug it.

No, it does not need electricity except for some AA batteries to turn on the gas valve by a switch on the unit or using the remote. I put this heater in myself last winter and love it! Puts out a lot of heat and gives some moisture during those dry winter months. They don't tell you in the manual, but I drilled some holes on the inside of each foot and put a tiny lag bolt through each foot (on the inside, cant see them) into the floor to bolt the unit in place.

No need power supply becaues it works off of the water pressure itself, so there is no electricity needed to run it. I used with my RO.

No electricity required. I would imagine it could be installed outside, but I would not unless you could lock access to it.

It comes ready to use right out of the box, nothing else is needed. The hardest part was cutting off the plastic holding it tight :)

No building necessary. It is put together in the box. Only the battery and wheels need to be put into o place.

No power is needed for this unit. You only need a water hose to hook up to..

Outside unit does NOT require a battery. Box only contains a speaker and wiring interface circuit board. batterys or external power are ONLY installed (applied) at the indoor unit.

It does not have a plug and would need to be wired into an electrical junction box.

Just plug it in! No assembly! Only work is filling it & putting chemicals in the water.

Sorry, I really don't know. But I would think the electrical wand and/or hose is necessary.

An enclosed patio would be best. It does use a pump, and some like to add a timer - these of course need electricity and protection from elements.

As others have said, it requires 12v DC. You'll need a power supply for operating it from household power.
