You pay for heat every month
Your building is already spending that energy. Make it earn Bitcoin too.
How to Work With Us
A building-integrated mining system does three things: displaces heating costs every winter, routes excess solar through hashing instead of the grid every summer, and exercises demand flexibility year-round — running on cheap off-peak electricity whenever the TOU rate and Bitcoin network economics make it the right call. Your system decides in real time. Pick the path that fits where you are.
Self-Serve
Free calculators, open-source smart home integrations, docs, and weekly office hours (Wed 10am MT). Figure it out yourself — we've made that possible.
Guided
We audit your building, design the integration plan, source hardware, and guide your install remotely. Available anywhere in the US.
Done-For-You
Full audit, hardware, installation, and commissioning. We handle everything. Local to Denver, CO (~100mi radius).

How Building-Integrated Mining Works
One device. Three value streams. No waste.
One watt in. One watt of heat out. Always.
Every watt a Bitcoin miner consumes becomes heat — 100% of it. Same conversion as your furnace, same thermodynamics as your laptop. The difference: a miner earns Bitcoin for every joule it runs. Every conventional heater does one job per watt. A miner does two. The second one doesn't cost extra.
Your heating load is your mining season
A miner sized to your building's average heat load runs at high duty cycle all winter, displacing your existing fuel. Every hour the furnace stays off is an hour of Bitcoin accumulation on electricity you were already spending. In our installs, the backup furnace rarely fires.
Your solar is worth more than your utility pays you
When your panels overproduce, that surplus exports to the grid at $0.01–$0.08/kWh. Route it through a miner instead: same watts, Bitcoin at hashprice. In our Solar Home case study — at their $0.01/kWh net metering rate — the same kilowatt-hour earned 3.3× more as Bitcoin than as a net metering credit. Your actual advantage depends on your local rate. In summer, your miner stops being a heater and starts being a solar arbitrage machine.
When the math is right, it mines for profit
When your off-peak electricity rate and the Bitcoin network's hashprice align, the system runs for pure profit — no heating load required. A conventional thermostat has one job. Your mining system knows your electricity rate, the Bitcoin price, your solar output, and the network hashprice — and makes the right call in real time.

See it in Action
Explore some of our most recent building-integrated mining projects
The Colorado Mountain Home
A single water-cooled miner drops into the existing mechanical room, hot water circulates to a radiator inside the furnace return duct, and the air handler distributes heat exactly as the furnace would — silently, invisibly, and with Bitcoin earnings on top. The goal: maximize hashrate uptime during the heating season. Gas exists only for backup.
Why Choose Exergy
We're specialists in an emerging industry - in fact, we're defining it
Control-First Architecture
Every Exergy system runs on Home Assistant — open-source, local, no cloud dependency. Your data stays on your network. Your system works if the internet goes down.
Building-Integrated, Not a Gadget
We integrate miners into your actual HVAC system — ductwork, radiant loops, hydronic circuits, solar arrays. Not a space heater you plug into a wall.
Real Installs, Real Data
Our case studies come from buildings we've actually built — with measured duty cycles, real Bitcoin earnings, and actual utility bill deltas. No theoretical projections.

Understand the basics of building-integrated mining
Does a Bitcoin miner actually heat my home?
Yes. In our Colorado Mountain Home, a single 4,000W miner handled 98.6% of the home's heat demand over a full heating season. The gas furnace ran for 4.4 hours total — across 43 days. The miner was the furnace.
Will my electric bill go up?
Yes — and that's the point. Electric goes up, gas drops to near-zero, and you accumulate Bitcoin on every joule. For propane and heating oil customers, the net result is often strongly positive before counting the Bitcoin. Our Exergy Audit shows you exactly where you land.
Is my building a good fit?
Strong fits: propane, heating oil, or expensive electric resistance heat. Solar with low net-metering rates. Pools, hot tubs, radiant floors. Weaker fits: cheap natural gas, heat pumps in mild climates. Run our free calculator — it tells you in two minutes.
