MINING HEAT · PHT ENERGY TECHNOLOGY
Your heating system can mine.
Compute Bitcoin. Make hot water. PHT delivers the heat from a water-cooled miner exactly where your building can use it.

ONE ENERGY FLOW · TWO USEFUL OUTPUTS
How computing power becomes hot water.
Four components connect Bitcoin mining to your heating system.
Power
Solar surplus or deliberately released energy.
Miner
Computing power is created — and so is heat.
Heat exchanger
Heat is transferred safely into the building circuit.
Storage
For hot water, heating, pools or process heat.
MINING REVENUE + USEFUL HEAT
What does the system produce in real numbers?
Example using a water-cooled premium miner: eight operating hours with genuine solar surplus and simultaneous useful heat demand.
Economic formulaGross mining revenue + value of useful heat − forgone export − operation − hardware
11.02 kWelectrical power
1.16 PH/shashrate
9.5 J/THefficiency
11.6 Rp./kWhgross mining
Gross mining revenue
88.2 kWh × 11.6 Rp./kWh over eight operating hours.
Useful heat
Using a cautious 90% heat-transfer assumption.
Gross system value
Mining plus heat valued at 12 Rp./kWh.
120-day scenario · 8 hours per day≈ CHF 2,370
Approximately CHF 1,227 gross mining revenue plus CHF 1,143 value from around 9,520 kWh of useful heat.
After forgone feed-in
≈ CHF 14.5per day with 8 operating hours
≈ CHF 1,735in the 120-day scenario
At a feed-in tariff of 6 Rp./kWh, the example forgoes ≈ CHF 5.3 per day (≈ CHF 635 over the 120-day scenario). Pool fees, pump power, maintenance, hardware, downtime and taxes are not yet deducted.
SUITABILITY CHECK
When mining heat becomes especially interesting
The better the power supply and heat demand match, the more useful the system can be.
- Solar surplus or deliberately available electricity
- Buffer tank or a suitable storage solution
- Demand for hot water, pool or process heat
- Heat pump, immersion heater or commercial application
PHT checks heat demand, hydraulics, connection and economics — without promising returns.

Could your building make useful use of Bitcoin heat?
Answer a few questions. PHT checks power supply, heat sinks, storage, heating system and the next technical steps.

BITCOIN HEAT IN EVERYDAY LIFE
What can Bitcoin heat do?
Much more than heating.
Showers & hot water
Store and use computing heat
Washing & dishwashing
Supply suitable appliances with hot water
Pool & wellness
Cover long, steady heat demand
Heat pump
Support suitable temperature tasks
MINER + HEAT PUMP
Two heat sources. Each doing the job it does best.
The heat pump is particularly efficient at low and medium temperatures. The miner can support hot water, the upper storage zone or other higher-temperature tasks.
- Heat pump for efficient base supply
- Miner for computing heat and targeted storage charging
- Joint control based on heat demand and available power
Planned realistically
Hydraulics, temperatures and the building profile determine the right division of work.
FREQUENT QUESTIONS
Short, clear and honest
Can every washing machine use miner heat?
No. Suitable machines need an approved hot-water connection or a professionally designed pre-feed solution. Permitted inlet temperature, wash programmes, hygiene and manufacturer specifications must be respected.
Does the miner replace a heat pump?
Usually not completely. A heat pump can provide several kilowatt-hours of heat from one kilowatt-hour of electricity. A miner produces roughly one heat kWh per electricity kWh plus variable Bitcoin computing revenue. In the right system, the two can complement each other.
What happens in summer when there is no heat demand?
Hot water, a pool or a drying room may use the heat. Without demand, the miner reduces output or pauses. Continued operation requires a properly sized heat-rejection system and its costs must be included. Unused heat is not a saving.
Are mining returns guaranteed?
No. Returns change with the Bitcoin market, network, hardware efficiency, pool, availability and costs. PHT therefore evaluates the overall benefit of computing, genuinely used heat and the electricity alternative.
