Solar-surplus mining with heat recovery

When solar generation exceeds what the building and battery can absorb, suitable computing hardware can operate as a controllable load. With water-cooled systems, heat can be transferred into the building’s thermal system.

Control technology for solar surplus and heat recovery
01

Energy follows clear priorities.

The building, battery reserve, hot water and other flexible loads come first. Only genuinely released capacity is assigned to mining.

  • Building consumption first
  • Minimum battery state of charge
  • Control based on PV surplus
  • Safe stop during grid import or faults
02

Waste heat becomes useful heat.

A closed water loop captures the hardware heat. A heat exchanger, pump group and buffer tank transfer it safely to hot water or heating.

  • Temperature and flow monitoring
  • Hydraulic separation
  • Buffer storage for timing
  • Defined safety limits and backup cooling
03

Electrical and heating systems designed together.

Martin Prünster covers power, protection, metering and control. Patrick Prünster matches temperature, hydraulics, storage and real heat demand.

04

Economics without return promises.

Heat value, avoided grid imports and possible mining revenue are evaluated separately. Hardware efficiency, network difficulty, prices, operating hours and regulation can change.

FAQ

Frequently asked questions

Does the miner use grid electricity?

Controls can restrict operation to defined PV surplus and battery levels. The exact priority is set for each project.

Does VoltAlps guarantee mining returns?

No. Mining income and payback are variable. VoltAlps assesses the energy and heat integration without guaranteeing returns.
