I = W/E. Current is equal to Watts divided by Volts. 1500/120 = 13 amps. A #14 is rated at 15 amps. A conductor can only be loaded to 80% for a continuous load so 80% of 15 equals 12 amps. Too small for the 1500 watt load. A #12 conductor is rated at 20 amps times 80% equals 16 amps for a continuous load. To answer your question, no, a #16 conductor will not handle a 1500 watt load.
12 volt electric heaters can range in price from 24.99 to 119.95 depending on how many watts you want. Price can also vary depending on other features you need such as a swing out handle or defrost setting.
Yes, the heater is a 240/120 heater, but I want to operate as 120 volt
Yes, the 265 volts is just the maximum the appliance can handle. You can use it on a 240 volt circuit.

Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.

No, it would overheat, might blow the fuse, otherwise it might catch fire.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.

2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.
