Loopenthal: Hydronic Lab
Hydronic commissioning lab
$2.99 · Designed for iPad. Not verified for macOS.
Model hydronic circuits, compare design targets with field readings, and export a complete commissioning record entirely on device.
Loopenthal is a native hydronic planning and field-commissioning workspace for heating professionals, facilities teams, designers, educators, and experienced system owners.
Build an editable hydronic project, model its terminal circuits, compare target and measured flow, and see the full supply-and-return system react as readings change.
NATIVE HYDRONIC WORKSPACE
- Editable projects with design supply/return, pump head, fluid, and outdoor conditions
- Radiant, panel-radiator, fan-coil, air-handler, and baseboard circuits
- Live supply-and-return schematic with balance status by branch
- Required flow from heat load and design temperature drop
- Pipe velocity and circuit friction-head estimates
- Valve Kv flow, valve pressure share, and authority calculations
- Index-circuit and available-pump-head comparison
- Outdoor-reset supply preview and curve
FIELD COMMISSIONING
- Enter measured flow, differential pressure, supply/return temperatures, and valve position
- Compare measured flow and delivered capacity with the design target
- Review visible warnings for flow error, velocity, valve authority, temperature drop, and pump-head limits
- Generate a native commissioning PDF containing every circuit, reading, result, note, and review item
ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase
- No login, account, ads, analytics, tracking, or developer-operated backend
- The complete sample and all core tools work offline
- Project data remains on the device unless you explicitly share a generated report
Loopenthal is an engineering planning and commissioning aid. Verify manufacturer data, field measurements, controls, applicable codes, and equipment limits before changing an operating system.
