Why Bitcoin Heaters Make Sense in the UK
UK electricity costs (February 2026): ~28p/kWh. If you're heating with electricity anyway, a Bitcoin heater turns a pure cost into an investment.
You're essentially getting a 20-30% discount on your electric heating just by choosing a Bitcoin heater!

How Much Bitcoin Can You Actually Mine?
Realistic Expectations (February 2026)
- Heatbit (20 TH/s): £0.60-0.90/day → £18-27/month → £220-325/year
- You'd be running a heater anyway — Bitcoin is a bonus!
- If BTC price doubles, your £20/month becomes £40/month
ROI Calculation
Heatbit at £899: Monthly net savings £20-25, payback period 36-45 months (3-4 years), 5-year total savings £1,200-1,500.
If Bitcoin price doubles, payback drops to just 18-22 months. And even if BTC goes to £0, you still have a working space heater!

Buy One If:
- You heat with electric radiators/space heaters
- You run heating 4+ months per year
- You're bullish on Bitcoin long-term

Skip It If:
- You have gas central heating (much cheaper per kWh)
- You live in a warm climate (no heating needed)
- You need absolute silence
- You can't afford £600-900 upfront

Running Costs
| Period | Electricity | Bitcoin Earned | Net Cost |
|---|---|---|---|
| Daily (8 hrs) | £3.36 | ~£0.75 | £2.61 |
| Monthly | £100.80 | ~£22.50 | £78.30 |
| 7-month season | £706 | ~£157 | £549 |

Environmental Impact
Both traditional and Bitcoin heaters use the same electricity and produce the same heat. The Bitcoin heater additionally secures the Bitcoin network — same carbon footprint, but the network becomes slightly more decentralised.
Common Questions
Will it heat my whole house?
No — it heats one room (200-300 sq ft), like a standard space heater. You'd need multiple units for a whole house.
How loud is it really?
Heatbit: 35-40 dB = quiet fan, library, whisper conversation. Many people sleep with it in the bedroom.
What if Bitcoin price crashes?
You still get heat! Even at £0 Bitcoin, it's equivalent to a regular electric heater.
Where to Buy
Heatbit (Recommended): heatbit.com — £899 + £50 shipping, 2-3 week delivery.
Used market: expect £500-700 for used units. Always buy from reputable sellers and check warranty status.
