Expansion Tank Sizing Calculator
Size bladder, diaphragm, or plain-steel expansion tanks for closed hydronic systems in seconds. This calculator applies thermal-expansion and pressure-ratio principles from Steven T. Taylor’s ASHRAE-referenced sizing method and the ASME Boiler and Pressure Vessel Code, Section VI, to compute the minimum required tank acceptance volume for hot water, chilled water, and mixed-temperature systems. Supports US and SI units, all four major tank styles, an optional piping-expansion credit, and a built-in ASME/UMC/IMC cross-check for 170–230°F systems — with clear pass/warning/invalid status and next-step guidance for tank selection and precharge verification.
Critical Radius of Insulation Calculator
Determines the critical radius (and critical thickness) of insulation for a cylinder or sphere — the outer radius at which heat loss is maximum — and compares heat‑loss rates before and after insulation.
