Is the RS15-6 Green okay for potable water systems?

You'd better try RS15-6 SS Green for potable water system.

Can this recirculate cold water instead of hot water? If i want to use it that way?

The question of hot water vs cold water pumps is a question about motor cooling. As a general idea, all hot water pumps can pump cold water regardless of manufacturer. This doesn’t hold for cryogenics though. TLDR - yes you can.

how is it on electrical consumption?

The info that came with it says 46 watts at the lowest (of 3) speed settings which is what I use. That's 81 kWh per year, pretty small. the highest speed setting uses 93 watts. I don't notice it on my electric bill but then I have a 3200 SF house (4 bdrm colonial) with air condition in the Northeast. It works great. I used to have cold water and have to wait 1 minute wide open running time to get hot water; now it's instantly warm and hot within 20 seconds. Also, you can put it on a time (or buy one with the timer installed) but I get up often in the middle of the night and like instant warm/hot water.

Are there instructions /operating manual available written in English?

Nope! It is cartoon drawn images for instructions. Not much to it.
