With increasing competition in Bitcoin mining, more operators are looking for ways to monetize the heat generated by miners. The Whatsminer M7 series from MicroBT offers one of the best solutions currently available.
The key difference lies in the suffix (D, AS, BS), which determines the maximum outlet water temperature.
Whatsminer M7 Series Comparison
Model Breakdown

Whatsminer M7D
Standard hydro model with outlet temperature up to 65°C. Ideal for traditional high-density data centers, but the heat is difficult to utilize for practical heating.
Whatsminer M7AS
Intermediate model. Outlet temperature up to 70°C. Suitable for domestic hot water (DHW) or low-temperature heating systems.
Whatsminer M7BS — Best for Heat Utilization
The most promising model. Outlet water temperature reaches 90°C. This allows direct use in central heating systems, industrial heat exchangers, and hot water supply. Thermal efficiency approaches nearly 100%.
Simple Rule:
M7D — pure mining
M7AS — mining + water heating
M7BS — mining + full building heating
When hash rate and efficiency are similar, the choice between M7AS and M7BS becomes a strategic decision: whether you want to monetize the heat or not.
