A physics-first planner for designing complete cold-plunge and ice-bath systems, from chiller sizing to pumps, filters, hoses, insulation, and cost.

Why it surfaced

ChillSizer refuses to treat a cold plunge as merely a tub plus a half-horsepower chiller. It models heat load, pump curves, filter restriction, plumbing losses, solar exposure, and cooldown ranges together, then links the calculations to equipment data and commissioning guides.

The Fax Is Thinking

August 8’s newborn domains include a chatbot that replies only by fax, an Elmira tax analysis built from 1,689 sales, a map protecting Jeju divers’ precise fishing grounds, and 58 boxes catalogued into one uncle’s 1,113-book library.

This is one of 1,000 discoveries in the 2026-08-08 Domain Arrivals issue.
