Disagree about "230v reserved for stoves and heating..."
I have a 240v in my living room for the in wall air conditioner. I COULD (if I felt like it) buy a 240v power conditioner and use that 240 outlet for my stereo (the conditioner I am thinking of uses 240 but outputs 120)
So it is no big deal to install a 240v outlet in a living room. The only thing as mentioned it must have the proper duplex so it can NEVER be mistaken for a 120v outlet.
About the 240v item combined with 120v items.. A very small possibility of an issue (like damaging the 120v stuff) exists if a short developed in just the right way in the 240v item.. But if you are willing to take the risk (low) then it would be up to you.
