What Is the Bitmain Antminer Z15?
The Bitmain Antminer Z15 is an Equihash miner producing 420 kSol/s at 1,510 W, an efficiency of about 3.6 J/kSol. Released in June 2020, it weighs roughly 9 kg and remains a common entry point into Zcash and Horizen mining.
The original Z15 is small, light and modest in power draw, which makes it far easier to place than most current-generation hardware. A single 240 V circuit comfortably supports it, and its 9 kg weight means no special handling or racking.
Its efficiency of 3.6 J/kSol is only slightly behind the Z15 Pro's 3.31 J/kSol, so on a cost-per-solution basis, second-hand and remaining new stock can still be competitive if acquisition cost is low.

Antminer Z15 Power Consumption & Electricity Cost
The Bitmain Antminer Z15 is rated at approximately 1510 W at the wall. Electricity is usually the largest recurring cost of running it, so estimate the draw at your own rate before committing to a deployment.
- Cost per hour
- $0.11
- Cost per day
- $2.54
- Cost per month (30 days)
- $76.10
Based on a rated draw of 1510 W at 100% uptime: power in kW × 24 × your rate. Real consumption varies with firmware, ambient conditions and uptime.
Antminer Z15 Cooling, Airflow & Noise
The Bitmain Antminer Z15 is air-cooled. It pulls cool air in one end and exhausts hot air out the other, so a deployment needs strict hot-aisle / cold-aisle separation, sufficient CFM per unit, and filtration to keep dust off the hashboards.
Air-cooled units are the simplest to install — no plumbing, no fluid — which makes them the practical choice for smaller sites, pilot deployments and containers that already have fan-wall ventilation. Keep intake temperatures within the manufacturer's operating range to avoid thermal throttling.
The trade-off is noise and density. Expect industrial noise levels at full load, which rules out residential and most office environments, and expect lower hashrate per square metre than an equivalent hydro or immersion setup.
Why Consider the Bitmain Antminer Z15?
Light and compact
About 9 kg and 133 mm wide — easy to ship, shelve and service.
Close to Pro efficiency
3.6 J/kSol versus 3.31 J/kSol for the Pro, at a much lower typical acquisition cost.
Who Is the Antminer Z15 Best For?
- Entry-level Equihash mining
- Sites with limited power per slot
- Buyers prioritising acquisition cost
- Testing Zcash mining before scaling
Bitmain Antminer Z15 vs Comparable Miners
How the Bitmain Antminer Z15 compares with the closest alternatives MinersDeals supplies on hashrate, power draw, efficiency and cooling.

|---|---|---|---|---|---|---|
| Bitmain Antminer Z15 | 420 kSol/s | Equihash | 1510 W | 3.6 J/kSol | Air cooling | June 2020 |
| Bitmain Antminer Z15 Pro | 840 kSol/s | Equihash | 2780 W | 3.31 J/kSol | Air cooling | June 2023 |
| Bitmain Antminer X9 | 1,000 kh/s (1 Mh/s) | RandomX | 2472 W | 2.47 J/kh | Air cooling | 2026 |

Efficiency (joules per unit of hashrate) determines how long a machine stays profitable as network difficulty rises, while total power draw determines what electrical and cooling infrastructure you need per unit. A more efficient miner is not automatically the better purchase — price per terahash, availability and the cost of the cooling infrastructure it demands all feed into the decision.
