HeatCore HS05

A compact water-cooled cabinet for one Whatsminer M64 bitcoin miner. It turns about 5 kW of mining heat into hot water for radiators, underfloor heating or a pool, and has a small fan cooler that can go outdoors to get rid of spare heat. It runs on a dedicated single-phase 220–240 V circuit. The miner is not listed among the included parts, and no shop lists a price: HeatCore sells it by quote.

*What a pool would pay on average at today's difficulty, block reward and bitcoin price, before pool fees. Solo miners usually earn nothing, and very rarely a whole block. A plain electric heater turns the same electricity into the same heat, so the mining income is what makes the difference.

Payback is how long the bitcoin a device earns takes to add up to its price. It leaves out electricity, which buys the heat: compare earnings per kWh with your electricity price to see whether mining alone covers it. It uses the average of the last 3 months, to 12 Nov 2026: bitcoin at $79,558, 969 EH/s on the network and 3.15 BTC a block, less a 2% pool fee, for the hours you set. It cuts the block subsidy in half at each halving, the next around Apr 2028, and otherwise assumes those carry on unchanged, which they won't. Income at today's difficulty and price is about 17% below that average. Hashrate usually rises, though miners that stop paying after a halving may switch off, which leaves more for the rest. How we work it out.
