Let me share something funny. Year after year my family could afford to heat only half of our appartment during the winters. This winter my rigs gathered in 1 room generate so much heat that the temps in all rooms are around 30 C. We are literally walking in T-shirts and eating ice creams while outside we have snow and temps -10 C. Not only that but we get paid for these heating devices so our income doubled. Life is great! Thanks Sir Claymore! 
that is beautiful! I heat my garage and workroom with the rigs and I got ~25C inside, windows opened, there is -3C outside
Unfortunately I can't use the heat to warm up the house. But till next winter I will figure it out how to use this heat to warm up the central heating's (water) buffer tank. I shouldn't waste the produced heat
