But i'm still gonna come up with some idea to use this heat!
I have connected my boiler as well. An old boiler is used for temporary heat storage, and water is circulated through a heat exchanger mounted on the input to the boiler in my house. When there is a temperature difference between cooling water going in to the heat exchanger and coming out of it, indicating that heat is consumed (hot water used), a pump switches on to force more water through the heat exchanger. The water is pre heated by my miner before it enters the boiler. I'm installing floor heating in my living room as well now. The old floor is almost out, and I expect to build the new floor next week.
