Recovered heat
A sealed, fluid-cooled computing system produces a steady stream of warm water that ties into a building's existing hydronic heating loop.
A Mansfield community heat project
Warmth for our public buildings, from clean, flexible computing.
Every winter, Mansfield burns fuel to heat the buildings we all own. Entropy Energy Network captures the warmth made by a small, sealed computing system and pipes it into those same buildings — lowering heating bills, cutting emissions, and giving the grid a shock absorber. Built in Mansfield, for Mansfield.
The idea in one sentence
Heat is the product. Compute is the means.
Computing makes heat — that’s physics. Almost everywhere, that warmth is blown into the sky. This project is built backwards from that waste: a compact, flexible computing load whose entire job is to hand its heat to the public buildings next door.
A flexible load
The computing load can turn down or pause within seconds when the regional grid is stressed — a shock absorber, never a strain.
Public benefit
Organizing as a 501(c)(4) social welfare organization, the project exists to serve Mansfield — not to maximize private profit.
Heat reuse, not heat waste
The same warmth, delivered where it's needed.
Recovered heat is delivered as hot water through standard, code-compliant hydronic plumbing — the same kind of system that already heats most schools and municipal buildings. There is no combustion on the heating side and no new fuel to buy.
The result is a quieter, cleaner source of building heat that can displace a meaningful share of a building's natural gas or oil use over the heating season.
