HydroniCalc vs HydroCalc

HydroniCalc brings together 23 hydronic calculators for heating engineers and installers of water-based heating systems. Everything runs in metric units, offline, and without an account. The calculators are grouped into four families: • Basic hydraulics and pipework: power, flow and temperature difference, diameter and velocity, linear and fitting pressure losses. • Valves, balancing and circulator: the Kv / flow / pressure-drop relationship, valve sizing, balancing, and the pump operating point. • Pressurization, volumes and separation: fill pressure, water expansion, expansion vessel, and system volumes. • Radiators and underfloor heating: radiator output correction, sizing, and underfloor loop length. Each calculator shows the values to enter and displays the result as soon as the required data is valid. An info button explains the purpose of the calculation, the expected inputs, the method, the results, and the usage limits. Built-in Kv tables: look up the Kv values published by manufacturers (manufacturer, product, and generation), then copy a value to paste into your calculation. The tables never fill a calculation automatically; the value is always typed or pasted into the field. Recent calculations: your ten most recent successful calculations are stored locally, so you can find them again and resume them with their values. Eleven calculators are free to use. A single, non-subscription purchase permanently unlocks the other twelve for the Apple account used. If a purchase isn’t recognized, “Restore Purchases” asks the App Store to sync it again.

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/ COMMISSIONING VISITS Record measured flow for each circuit and compare it with the design targets frozen when the visit is saved. An adjustable project tolerance makes deviations clear. Earlier visits remain unchanged after later design edits. Calculated targets and measured values stay separate.
