Bitcoin Mining as Your Home Heater? This Startup Is Making It Real

Hear me out: What if your space heater could mine Bitcoin while keeping you warm—and actually save you money on energy bills?

That’s exactly what Zack Bomsta, a former electrical engineer turned crypto entrepreneur, is piloting through his company unbound NETWORKS. The concept is deceptively simple: Bitcoin miners generate massive heat as a byproduct of complex calculations. Instead of wasting that thermal energy, why not use it to warm your home?

How it actually works

His plug-and-play system lets homeowners host small-scale miners that function like sophisticated space heaters. The pitch? Cut your heating costs by $200-$600 monthly depending on location and market conditions. Plus, you pocket 5-35% of the Bitcoin generated.

The miners themselves are boxy devices roughly the size of an air purifier, with noise levels comparable to typical space heaters. Installation is handled professionally—just plug them in, connect to Wi-Fi, and control temperatures like a standard thermostat.

The math that makes sense

The economics only work in specific regions: Wyoming, Idaho, Washington, Oregon, North/South Dakota, and Montana lead the pack. Why? Cheap electricity + expensive propane = profit.

Meanwhile, DIY enthusiasts like Cody Harris are building their own systems. His homemade setup costs ~$3,500 (comparable to a propane boiler) and last winter produced enough Bitcoin to offset his entire electricity spend. “I was basically producing free power,” Harris recalls.

The real play

It’s not about getting rich quick—it’s about energy arbitrage. Whoever has the cheapest electricity wins. For homeowners in cold climates with cheap power rates, this could genuinely be the future of heating. The barrier? You need to live in the right region with the right energy prices. Outside that, it’s just an expensive space heater that mines pennies.
