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.
Newer homes built in the US are more efficient and don't require amperage like the in the past. That's why you see 100 AMP service for a normal size 3 bedroom 2 bath house now. My house was built in the year 2000, which is considered new in the housing world and came with 100amp service. If the house was 20 years old, I bet it would have 200-300 amp panel in the basement.
It depends on the area and what the house is capable of supporting as well. There's no universal standard for what it will come with. The last house I was in had a 240 or 260 amp service, and one of my friend's recently built houses had 200 despite being under 2000sq/ft. YMMV.
TBH I've never seen just 100amp in a 3br/2bth, new or old.
