WHAT WE KNOW.
WHAT WE KNOW.
WHAT WE ARE STILL BUILDING. CloudBoiler is under development.
Here is the clearest current picture of the platform, its intended uses, and the questions still being validated.
01
MANIFESTO
Your home is becoming the edge of the compute grid.
Every AI inference, every render, every simulation generates heat. CloudBoiler is being developed to route that heat where a home can actually use it.
Compute creates heat
Every workload — AI inference, rendering, simulation — generates thermal energy. CloudBoiler is being designed to capture it at the source.
One home, many uses
Recovered heat routes through a managed thermal bus to household branches you choose to enable — hot water, hydronics, storage, and more.
Managed, not one-off
Isolation, service states, and controlled rejection keep the platform safe and serviceable across time — not an appliance you throw away.
02
HOW IT WORKS
From compute work to useful home heat.
Computers create heat as they work. CloudBoiler is being developed to recover that heat and make it available to a managed network of household thermal uses.
Receive the recovered heat through a managed domestic thermal bus.
Direct thermal energy among selectable household branches.
Apply it to hot water, air heating, hydronics, storage, pools, or other supported thermal loads.
Support isolation, purge, fill, bleed, recommissioning, and controlled heat rejection at a high level.

CORE DEVELOPMENT CATEGORYHydronic space heating
Route heat to compatible radiators, fan coils, baseboard, or radiant systems.
ENGINEERING REVIEWHVAC / heated air
Transfer recovered heat into conditioned air through an air-side hydronic accessory.
FUTURE PILOT CATEGORYThermal storage
Store useful heat in buffer or thermal-mass systems for later use.
CORE DEVELOPMENT CATEGORYPool / spa

SYSTEM LAYERS
One platform, five clean layers.
A shared model for what CloudBoiler is designed to do — from compute to routed household heat.
01
COMPUTE SOURCE

WHY IT MATTERS
Three ideas, one flexible platform.
01
USE HEAT TWICE
Compute consumes electricity and creates heat. CloudBoiler seeks to make that heat useful.
02
MOVE COMPUTE CLOSER TO THE LOAD
Distributed compute can place thermal output near the homes and buildings that can use it.
03
BUILD A FLEXIBLE THERMAL PLATFORM
A branchable system can serve more than one appliance or one thermal use.

FAQ
Questions, answered honestly.
CloudBoiler is under development. Answers below are high-level and reflect the current design intent — not final specifications, guarantees, or commitments.
A PLATFORM
What is CloudBoiler?
CloudBoiler is a whole-home thermal platform being developed to recover heat from compute hardware and route it to selected household thermal branches through a managed thermal bus.
Is CloudBoiler only a water heater?
No. Hot water is one supported branch. The platform is being designed to also serve hydronic space heating, HVAC, thermal storage, pool/spa, and controlled rejection where those branches apply.
What is a thermal bus?
A managed loop that receives recovered heat from the compute source and makes it available to the household thermal branches the platform is configured to serve.
What does branchable mean?
A common thermal network can serve multiple household thermal categories. Different homes may enable different combinations of branches.
What does serviceable mean?
Branches are being designed to support isolation, purge, fill, bleed, and recommissioning concepts so the platform stays maintainable over time.
B THERMAL USES
What can the recovered heat be used for?
Depending on the configuration: domestic hot water, hydronic space heating, HVAC (through an air-side accessory), thermal storage, pool or spa heating, and a controlled rejection path for excess heat.
Does every home need every branch?
No. Branches are optional and homes are expected to enable the ones that match their thermal needs and system compatibility.
Can it support hot water?
Domestic hot water is a core development category for the platform.
Can it support heating or HVAC?
Hydronic space heating is in engineering review. HVAC / heated air via an air-side hydronic accessory is a future pilot category.
What happens when the home cannot use more heat?
A controlled heat-rejection path is being developed as a managed fallback when household thermal loads cannot accept more heat.
C COMPUTE
What kind of compute hardware may work with CloudBoiler?
Integrated CloudBoiler compute is the core development category. Liquid-cooled AI or server hardware is in engineering review. Owner-provided hardware through source-adapter concepts is a future pilot category.
What is BYOC?
Bring Your Own Compute — a developmental concept that would allow compatible owner-provided hardware to participate as a heat source through supported thermal interfaces.
Can I connect my gaming computer?
A future heat-extractor or source-adapter concept for gaming rigs and workstations is under exploration. It is not a shipping capability today.
Is compatibility guaranteed?
No. Not every computer will be compatible, and there is no universal retrofit promise. A final compatibility list does not yet exist.
Does CloudBoiler guarantee compute income?
No. There is no guaranteed compute utilization, workload availability, or income from the platform.
Does it guarantee private or offline AI?
No. Some configurations may support local or distributed compute use cases, but total privacy, offline AI, or guaranteed cybersecurity are not promised.
D INSTALLATION AND SERVICE
Can homeowners install it themselves?
No. CloudBoiler is not a consumer self-installation product. Field installation and service by qualified professionals is expected.
Who would install and service it?
Practical deployment is expected to involve field installation, service, energy-program coordination, and appropriate professional review. The specific installer network is being developed.
Is the system certified?
No specific certifications are being claimed. Any final certifications will depend on engineering validation and applicable review.
Is it available in every jurisdiction?
No. Availability, permitting, and applicable regulations will vary by jurisdiction.
What is still being engineered?
CloudBoiler is in development. Final configuration, compatibility and installation requirements will depend on engineering validation, site conditions and applicable professional review.
E PILOT AND AVAILABILITY
Can I buy one now?
No. CloudBoiler is not on sale. The current program is a pilot/waitlist for homeowners, engineers, installers, and strategic partners.
Is this a pre-order?
No. Joining the pilot waitlist is free, non-binding, and is not a pre-order.
How do I join the pilot list?
Register interest via the pilot waitlist form on the Pilot & Partners page. The team will follow up when relevant.
Who is a good pilot candidate?
Homeowners with the right site conditions, engineers and installers with relevant expertise, property owners and portfolio operators, utilities and program operators, and compute or energy strategic partners.
When will installations begin?
No public installation dates are being committed. Prototype and pilot installation timing depends on engineering validation and pilot selection.
How are pilot participants selected?
Interest → site screening → technical fit review → engineering and installation planning → prototype or pilot agreement → installation and validation → monitoring and learning.

Can builders, utilities, installers or compute providers participate?
Yes — the pilot program is being developed with a range of homeowner and partner categories. Reach out via the pilot form or contact the team directly.
Can a company propose a pilot?
Yes. Companies exploring a pilot deployment or partnership can propose a pilot scope through the pilot waitlist or by contacting the team.
