Flipping a building’s heat
A Bitcoin miner turns nearly all the electricity it uses into heat. When a building uses that heat instead of buying heat separately, its heating is no longer a pure cost: the same electricity heats the building and also mines bitcoin.
Main test caseThe Bitcoin Home11 heat reuses
Heat per bitcoin
Heat delivered ÷ Bitcoin mined
kWh per BTC, over the same period
Heat yield
Income ÷ Heat delivered
CAD per kWh of useful heat
In a building, the same heat can be used more than once, moving from higher-temperature uses to lower ones, for example space heating, then hot water, then pre-heating air or floors. The Bitcoin Home counts 11 heat reuses, including the pool, fireplace, sauna, greenhouse, dishwasher, clothes dryer and hot water tank.
The Bitcoin Home is the BEE team’s own test case. No claim is made about any builder listed on this site.
