confused on heated o2 sensor

Sorry to bother, but i searched and kept gettin mixed thoughts. Just a quick question, Can I run heated o2 sensor all the time. As in keeping it powered all the time? I was just going too have the exhaust shop weld it in the collector. I know if I were to run it close to the original spot I couldnt because it would get too hot. But I am runnin Doug's Lt headers also, so t would be farther away.

Yes you can run it powered all the time. It doesnt take much power to run, but when the car is off, you're draining your battery.

Yes, all the factory HO2s I know of are constant ignition hot

I would suggest adding a fuse for these too
