An ASIC converts electricity to two things; sha256 hashrate and heat. The hashrate is used but hardly economical where I live (Nordics) on its own. However, my point is that the heat can be utilized and offset the cost. An ASIC mineraloil cooling loop can be connected to a separate water based heating system-loop via an heat exchanger. So you get a SHA256 to sell to compensate the electricity you would need to heat the water anyway. Even with inefficient miners you can profit when accounting for heating costs offset. There are examples on youtube with DIY setups - but no proper product where this is built as a home heating system based on heating by a sha256 ASICs...that's is what I want and even non-bitcoiners would love to save 50-90% on heating costs.
