Measure genuine surplus
Operate only within defined windows and avoid unintended grid import.
Optional specialist solution
Computing power only where surplus and heat demand coincide.
PHT treats mining as a controllable electrical load with usable heat, not as a guaranteed investment return.

What this solution delivers
Use the heat properly
Temperature, hydraulics and seasonal demand must align.
Design electrical safety
Assess continuous load, cables, protection, ventilation, noise and fire risk.
Model risk transparently
Separate lost export value, displaced heat, mining revenue and all costs.
MORE EVERYDAY USES
Compact technology. More ways to use heat.
Small footprint
A compact miner can fit into a limited space. The complete installation also needs cooling equipment, a heat exchanger, storage and maintenance clearances, depending on the device and building.
Support basement drying
Recovered heat can warm damp basements and support drying. Moisture must be removed through controlled ventilation or a dehumidifier, and the cause of dampness must be addressed.
Dry laundry with recovered heat
A suitable heat exchanger and air heater can transfer hydro-miner heat to a drying room. Ventilation or dehumidification removes the evaporated moisture. Never place laundry on the miner.
What happens to the heat in summer?
Hot water, a pool or a drying room may still need heat. Once storage is warm and there is no demand, the miner reduces output or pauses. Operation without heat use requires a properly sized heat-rejection system, adding costs without heat-saving credit.
For basements: heat alone does not remove water. Warm, humid summer air can condense on cool walls. Plan ventilation around moisture conditions; have mould or water ingress professionally assessed first. Cooling, equipment protection and safe clearances remain essential.
Process

Technical concept
Plan power, cooling, heat exchanger, hydraulics and controls.
Safe integration
Install electrical protection, sensors and operating limits.
Measure real performance
Track grid import, useful heat, run time and actual costs.

Questions to answer before proceeding
Opportunity cost
Every mining kWh could instead be exported, stored or used for heat.
Seasonal heat use
Summer heat may have little value without a heat sink.
No return guarantee
Revenue and hardware value can change substantially. Technical design is not financial, tax or legal advice.
Service area
Serving Pfäffikon SZ, Freienbach, Wollerau, Lachen, the Canton of Schwyz, the Lake Zurich region, Glarus and, depending on the project, wider areas.
A real project depends on the grid connection, current tariffs, shading, building services, permissions and measured demand. PHT combines these local facts with an integrated system design.

Frequently asked questions
Frequently asked questions
Is mining with solar power free?
No. Solar electricity has an alternative value and equipment, cooling and maintenance cost money.
Can a miner replace a heat pump?
Not generally. A miner produces roughly one unit of heat per unit of electricity; a heat pump can produce several under suitable conditions.
How is the miner controlled?
Depending on the device, by power stages, software interface, electrical enable or an external controller.
Who addresses tax and legal questions?
PHT designs the technical integration. Tax, legal and financial matters require qualified advisers.
