Bedroom? How old are you? Do you just rent a room or a house or something? You have BIG balls if you are going to run an SP30 in a room. First it's huge. Double the size of the SP10 and weighs quite a bit. When shipped, it is considered "freight" and not a package because it weighs so much. I have 100 amp service, could get away with running my SP10 but the noise was too much. I can just see you....when trying to wash clothes have to turn the miners off, then switch back real quick after the last load. Is you stove electric to? Yikes, can't make that mac-n-cheese when mining away! 
100 amps isn't really much, I had that running in a tiny GPU farm in a small office. With the right cooling in place, it was nearly silent. If someone wanted to run an SP30 in a bedroom, I'm sure they could do it, and with the right mods it could be done well.
Not sure where you are in the world, but most american homes use 200-300 amp service.
