I am buying an antminer R4 from a member on here. I have decided that due to living in a colder climate, me and my partner are going to do our own custom painted casing of a nice fake fireplace which we can slip the R4 into.
Colder winter months this will act as a 24/7 fan heater, summer months I can remove the miner from the fake 'fire' and put it in the brick and mortar shed where I have destined the rest of the farm to be. Has proper electrics wired in by a qualified electrician so I am happy. Homeplugs to bring Ethernet into there means I am away!
A novel thing to do with the antminer R4, I think it will look sexy and will be able to make money in the process, I have a lock in with sainsburys energy for two years with a 10.6p day and 4.5p night rate (economy 7) (I have never found a deal like it, it averages at 8 pence I think, you cant get this rate getting it with them directly) when the promo ran out I was able to convince them to lock me onto the rate for two years. *rubs hands together*
I will add that in the UK energy that cheap is simply unheard of in a residential property. the best deal I could find outside of it was 7p night 11.5p day rate. I will make the most of this tariff while I have it!
In the winter heating cost is needed anyway so I wouldn't class that as eating into mining profit from a machine like this, in the summer it would but I can move it out the way so as not to bake!
That is very low for the UK, good luck, but I don't think the R4 generates that much heat from what I have read by others that have them.
