Running with two Antminer S19J Pro producing around 7kWh, the immersion oil can be heated up to 150F/65C, enough for heating house, pool and water. Any other miners can also be used.
Each consumer has its own oil loop and control system, which tells the central brain (Home Assistant) about temperature and status. The brain turns on the miners and pump and decides which loop receive oil and opens the valves. Each loop can run individually or all together.
The House is heated through the existing two zone baseboard and radiator heating system, which circulates hot water throughout the house. A plate heat exchanger installed into the existing system transfers the heat from the Bitcool to the water and heats the house.
The Water is heated with circulating the cold water from the bottom of the existing tank through a heat exchanger back into the cold water inlet of the tank. The existing thermostats on the tank are used to know when the hot water in the tank is cold and needs heat.
The Hot Tub is located in the yard, the water is pumped to the house, heated through a heat exchanger and back out to the hot tub. A temperature sensor in the Hot Tub tells us when it's hot enough to be enjoyed.
