About

HydroCalc is a calculation aid for heating and HVAC technicians. Calculate flow from heat output and temperature difference alongside the existing hydraulic calculators. CIRCUIT PROJECTS Create named projects and group circuits by room, category or floor. Record heat output, temperature difference and input sources for each circuit. View total heat output and required flow together. BASELINE AND COMPARISON Capture a fixed baseline and edit later proposals independently. Review differences in totals and share a calculation worksheet with inputs, sources and comparison. German and English. Local projects and calculations work offline. Existing purchase unlocks remain available. Professional calculation aid: manufacturer data, applicable rules, system design and actual measurements take precedence. Check results against the real installation. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
