⛏️ Hydro Miner Heat Reuse Calculator
Ever wondered what your electricity really costs when you consider the heat you’re getting?
Background
So I’ve been using hydro miners to heat my place for a while now. Whenever I break down the numbers for someone, I always end up doing the math on a napkin:
"Your actual electricity cost isn't €0.22/kWh; it’s more like €0.10 if you consider the heating you’re saving money on."
I realized no one had made a proper calculator for this, so I decided to create one.

What it calculates
Most tools that claim to measure "mining profitability" treat electricity as just a cost. They overlook that a hydro miner turns 98% of its energy usage into heat that you’d normally get from your boiler, heat pump, or pellet stove.
This calculator gives you the full scoop:
- Outdoor temperature slider (from −25°C to +15°C) lets you see how your savings can change between a chilly January and a mild October.
- It also looks at heat pump COP drop-off. The rated COP is set at +7°C, but at −20°C it can fall to about 1.5. Unlike most calculators, this one adjusts for that.
- There's a heating degree-day model based on your home’s size (in m²) and energy efficiency (A+ to G).
- It compares different heating types gas, heat pumps, pellets, or oil and shows you how they stack up economically.
- Live BTC/LTC/DOGE prices fetched straight from CoinGecko when you load the page.
- You can toggle between EUR and USD for all outputs.
- Most importantly, it gives you the effective kWh rate that really matters for your situation.
The core formula is clear:
Energy class factors (kWh/m²/year): A+ = 54, A = 100, B = 155, C = 220, D = 300, E = 380.
As a reference, a 450 m² A+ house at −20°C needs about ~6,500 kWh/month on average. Just matches.

It's almost thesame concept with using ordinary miners in places like Siberia. The heat from the miners compensate for the cost of heating a home with dedicated home heater, so you subtract the heat from the actual cost of mining, and your mining cost becomes lower than it should be, compared to mining in tropical regions. This is why they are recommended in colder regions. And the slight difference between hydro miners and ordinary miners is that the former mabe mild on mining hardware due to the additional cooling factor from water compared to just the cool weather. This could make the miners last longer and the cost of mining abit lower than ordinary miners
The heat factor is why such miners are best used in very cold environments as they help make Bitcoin mining energy efficient. And you may aswell call them home heaters that mine bitcoins.
