Two bitmain antminer l3+ most likely wont cause too much of a heating issue for you. As long as you have some kind of ventilation. Even a window or a open door. But i think the noise is whats going to annoy the sht out of you. These bitmain miners are really not produced for home use, especially in a office space or living room. But if you must go for it, just dont know how your going to work with the noise these things are producing.
Noise is the main issue of antminer series all hardware. If want to mine with the good miner, always better go with the antminer s9 still heating issue is very lower at the same time noise is the big trouble for the miners you invested on it.
If you have glass door window and air conditioned room. I think that is best to have your miners in that.
