Kaspa miners (kHeavyHash)
ASIC miners for the kHeavyHash algorithm for mining Kaspa (KAS) – from the Antminer KS7 to the IceRiver KS7. For every machine you can see the hashrate in TH/s, power draw, efficiency and earnings in CZK recalculated for today's network difficulty and exchange rate.
Kaspa is a fast blockDAG network whose block reward decreases every month, so it makes most sense to compare the efficiency of the machines. We sell miners with an invoice and warranty, service them in Prague 10, and you can place them in our hosting.
- 4models available
- 2–45 TH/s hashrate
- from 77.0 J/THefficiency
- from 14 399 Kčprice
- Air 4 cooling
- up to ≈ 162 Kčrevenue / day today (before electricity)
Profit = today’s revenue based on network difficulty and the exchange rate − electricity at the selected price. Our hosting = the cheapest location with free capacity (Nigeria #2), price converted from USD at today’s exchange rate. Revenue changes; this is not a forecast.

How to choose a Kaspa miner
First decide where the machine will run – that determines the cooling. For each type we show the machines from this collection that earn the most today from 1 kWh of electricity.
-
hosting, workshop
Air-cooled
The most common and cheapest option: fans cool the machine, so it only needs a supply of cool air and a way to remove the heat. It is loud, though (usually 70–80 dB), so it does not belong in a flat – it suits our hosting, a workshop or a plant room, and at home only with a soundproof box.
4 models in this collection, most profitable per 1 kWh:
How hosting works -
quieter, heat for heating
Hydro (water cooling)
A liquid in a closed loop cools the chips and a dry cooler or heat exchanger removes the heat. Hydro machines are quieter and more powerful, but they need a water loop and usually a three-phase supply. You can use the heat to warm water or for heating.
There are none in this collection right now. Write to us – we will check availability.
Water loops for Hydro -
farms, almost silent
Immersion cooling
The machine is submerged in dielectric fluid in an immersion tank – it is almost silent and the chips stay at an even temperature. It needs a tank, a pump and a cooler, so it is best suited to farms and hosting.

Kaspa miner comparison
Sorted from the most efficient – fewest joules per unit of hashrate. We recalculate revenue every hour, and profit using the electricity price selected above the miners: on hosting at 1.14 Kč/kWh.
| Model | Hashrate | Power | Efficiency | Cooling | Noise | Price from | Revenue / day | Profit / day |
|---|---|---|---|---|---|---|---|---|
| Antminer KS7 | 45 TH/s | 3,465 W | 77.0 J/TH | Air | 75 dB | from 71 599 Kč | 162 Kč | 67.50 Kč |
| IceRiver KS7 30 TH/s | 30 TH/s | 3,500 W | 117 J/TH | Air | 75 dB | from 46 458 Kč | 108 Kč | 12.44 Kč |
| IceRiver KS7 Lite | 4.2 TH/s | 500 W | 119 J/TH | Air | 50 dB | 23 399 Kč | 15.15 Kč | 1.47 Kč |
| IceRiver KS2 Lite | 2 TH/s | 500 W | 250 J/TH | Air | – | 14 399 Kč | 7.21 Kč | −6.47 Kč |
Hashrate, power draw and noise are stated by the manufacturers. Efficiency = power draw ÷ hashrate. Revenue = hashrate × today’s revenue of the algorithm’s most profitable coin (before electricity and pool fees); profit = revenue − electricity at the selected price. For machines with several hashrate options we use the base hashrate from the product card.
At home or on our hosting?
The result of mining depends mainly on the electricity price. Comparison for the machine in this collection that earns the most per 1 kWh – Antminer KS7.
At home or at your business
- Grid electricity costs a Czech household roughly 4.5–6.5 Kč/kWh (2026); it is cheaper from your own solar panels or on a business tariff.
- A powerful ASIC needs its own circuit and ventilation, and you have to expect noise – air-cooled machines are usually 70–80 dB.
- You can use the miner’s heat for heating, but in summer you have to get rid of it.
Profit at 4.5 Kč/kWh: −212 Kč / day
On our hosting
- Electricity from 1.14 Kč/kWh including management (Nigeria #2), 7 locations with free capacity.
- With prepaid electricity, up to 30% cheaper.
- New miners bought from us that run on our hosting come with a 7-year warranty. We take care of noise, cooling and repairs.
Profit at 1.14 Kč/kWh: 67.50 Kč / day
Profit = today’s revenue − electricity for 24 hours, before pool fees. Network difficulty and the exchange rate change; this is neither a forecast nor a promise of revenue.
FAQ about Kaspa miners
How much does a Kaspa miner earn per day?
Revenue depends on the machine's hashrate in TH/s, network difficulty and the KAS price. We show the current value for each model on its card and in the comparison table; the switch above the listings shows the profit after electricity at your kWh price.
Why does Kaspa revenue keep falling?
Kaspa's block reward decreases every month (by roughly half per year), and network hashrate grows as new machines arrive. Revenue in KAS therefore falls over the long term – in fiat it depends mainly on the price. When choosing a machine, keep an eye on efficiency and the cost of electricity.
Which wallet should I use for Kaspa?
The pool sends mined KAS to your address. We explain how to create and secure a wallet in the guide Kaspa wallet.
How do I set up a Kaspa miner?
Connect the machine to the network, enter the pool and wallet address in the web interface and start mining. You will find the procedure for IceRiver machines in the guide Setting up IceRiver KS0 and KS3; our service team can also set it up and get it running for you.
Can Kaspa be mined together with another coin?
Some pools offer simultaneous mining with the Canxium coin. We discuss how it works and what the risks are in the guide Kaspa and Canxium.
