Unless your landlord is a complete fool, there will be a fair use policy in your tenancy agreement, and that will most certainly preclude the use of a Bitcoin miner running 24/7.

'All bills included' accommodation is quite popular in the UK (known as HMO's), and very often people try to get away with running ASIC miners, however they are typically caught and stopped very quickly.

What you're basically planning to do is exploit your landlord, and it's not cool.
