If you only have 1000kwh per month for Bitcoin mining you can only use S9 miner that consumed around 1400w per hour and around 1000kw in a month.
Or if you are looking for Bitcoin miner that doesn't consumed much power check USb miner like Compac F 48 pieces of them can hash around 14.4th/s with very low power consumption.
Unfortunately, today it is very difficult to find an ASIC Antminer S9, because it has been on sale since mid-2016. Or buy several ASICs for block repairs. But asics make a lot of noise, which will be a bad solution for mining in the house, and mining a farm from video cards does not make much noise.
