Generate
The miner performs Bitcoin computation and produces a predictable thermal output.
DIGITAL HEATING / NEW ZEALAND
Turn mining heat into useful energy.
Bitcoin miners produce steady, valuable heat whenever they run. ASIC.NZ designs systems that capture that output for space, water, and process heating—improving the economics of the same electricity you already use.

One energy billfor both computing and useful heating
THE CONCEPT
Heat is not a byproduct. It is part of the return.
A miner converts electrical energy into computation and heat. Conventional setups throw that heat outside. Digital heating redirects it to a load you would otherwise pay to heat separately.
Capture
Air ducts or immersion cooling collect the heat instead of exhausting it as waste.
Reuse
The captured energy heats rooms, water circuits, pools, greenhouses, or processes.
RECOVERY METHODS
The right system depends on where the heat needs to go.
Air to air
The simplest route to useful space heating.
Insulate the miner, control its airflow, and duct warm exhaust into the target area. Best suited to homes, workshops, and smaller commercial spaces.
Lower setup complexityImmersion to water
Flexible heat recovery for larger loads.
Transfer heat from dielectric fluid through a heat exchanger into a water circuit. Ideal for cylinders, hydronics, pools, greenhouses, and industrial use.

Useful-heat principle1 kWh in≈ 1 kWh of heat
Almost all electricity consumed by a miner ultimately becomes recoverable thermal energy.
THE ECONOMIC CASE
Offset a cost you already have.
Mining revenue and heating value come from the same power draw. Where the recovered heat replaces electric, gas, or other purchased heating, that avoided cost improves the effective return of the deployment.
- Start with the real seasonal heat demand
- Size hardware around usable thermal output
- Account for noise, airflow, plumbing, and controls
COMMON QUESTIONS
What to consider before choosing a system.
Can a miner replace a conventional heater?
It can supply a comparable continuous heat output, but the right answer depends on room size, insulation, climate, controls, and whether mining operation matches the heating schedule.
What happens when heat is not needed?
The design needs a safe rejection path. That may mean seasonal ducting, an outdoor radiator, a dry cooler, or reducing miner operation when there is no useful heat load.
Is immersion cooling always required?
No. Air recovery is often the most practical residential entry point. Immersion becomes attractive when transferring heat into water or operating at larger scale.
What information do you need to assess a project?
Tell us the location, intended heating application, approximate heat demand, available electrical capacity, existing equipment, budget, and whether mining hardware is already installed.
