Heatbit Maxi Pro Space Heater Mines Bitcoin to Offset Electricity Costs
The Heatbit Maxi Pro is a space heater that mines Bitcoin using its heat-generating components, aiming to reduce electricity expenses amid rising U.S. residential rates. Wired reviewed the device, which costs $1,499 and includes a HEPA filter, but found its mining output insufficient to cover costs at current Bitcoin prices.

Residential electricity rates in the United States have increased more than 40 percent since 2020, reaching levels reported as of February 2026. Extreme weather events have contributed to higher heating and cooling bills. The Heatbit Maxi Pro, priced at $1,499, functions as a space heater that simultaneously mines Bitcoin to potentially offset these costs.
The device generates heat through its Bitcoin mining process, which uses the same electricity that powers traditional space heaters. Manufacturers describe this as 'smart heat' compared to 'dumb heat' from standard heaters that do not produce additional output. The Heatbit Maxi Pro also incorporates a HEPA filter to clean air passing through it.
Bitcoin mining has faced challenges in recent months due to high electricity costs, increased mining difficulty, and a six-month decline in Bitcoin's value. These factors have made mining unprofitable for most residential users. The Heatbit Maxi Pro does not compete directly with dedicated mining hardware but seeks to repurpose the energy used for heating into cryptocurrency generation.
Wired's review tested the device's performance as both a heater and miner. It found the Heatbit Maxi Pro less effective as a heater compared to other space heaters on the market. Additionally, its energy efficiency for Bitcoin mining trails that of specialized miners.
Calculations in the review indicate that at current Bitcoin prices, the mining revenue does not cover the device's electricity consumption. Potential savings would require years to materialize, depending on usage timing and location-specific factors like electricity rates and climate. Users in regions with lower rates or milder weather may see limited benefits.
The product's introduction occurs amid broader shifts in cryptocurrency mining, where profitability has declined for small-scale operations. Residential users affected include those facing high energy bills, particularly in areas with volatile weather. Future developments could involve adjustments to mining algorithms or Bitcoin's market value, potentially altering the device's viability.
