Important — planning tool, not a certified report
All heat-loss, output, pressure and flow figures are planning estimates based on simplified physical models (U·A·ΔT, cell-based UFH output, Darcy–Weisbach, etc.). They do not replace a certified DIN/EN design report or manufacturer guarantees. Inputs and results should be reviewed by a qualified professional before you build or order materials.
Features
Everything for a thoughtful UFH layout
From PDF import or blank sheet to pipe lengths, hydraulic hints and a printable project report.
Model the building
Walls with layered build-up and exterior insulation, openings, rooms, storeys and reference floor below.
Heating areas & pipes
Heating zones, blocked areas, place manifolds and draw circuits manually with bend-radius checks.
Heat loss & output
Per-room loss and UFH output estimates — including q′, W/m², reserve and status per room.
Hydraulics (planning)
Recommended flow, ΔT hints, pressure-drop estimates and balancing overview on the manifold.
Export & diagnostics
PDF project report, heat map (qArea), diagnostics list and per-room calculation report.
Typical workflow
From plan to results in a few steps
Create a project
Import a plan or use a blank sheet with size and scale. Set units and heat sources.
Building & rooms
Draw walls, define rooms with floor/ceiling build-up, target temperature and openings.
Lay out UFH
Heating zones inside rooms, place manifolds, draw circuits and assign outlets.
Review & export
Heat-loss dashboard, project diagnostics and PDF report — for your records and installer meetings.
Results
What you get at the end
Pipe lengths per circuitHeated, connection, vertical (manifold height) and total — for material and manifold planning.
Volume & flow ratePipe volume at the manifold and recommended flow (l/min) from heat load and ΔT — planning values.
Heat-loss overviewPer room: area, losses (floor, walls, ceiling, openings, ventilation), W/m² and data-quality hints.
UFH output & reserveAchieved output, required W/m², q′ and margin/deficit — with status per room.
Heat map (PDF)Area heat map of specific output qArea (W/m²) — A4 to A1, portrait or landscape.
Full project PDF reportFloor plan, tables, per-room calculation reports, floor build-up appendix, diagnostics and planning notice.

UFH on Mac
Underfloor heating planning software — built for macOS
Planning hydronic underfloor heating means working from a floor plan, estimating pipe lengths, and checking whether output matches heat demand. MyHeating Designer is underfloor heating software for Mac (Mac App Store) — not a Windows CAD suite, not radiators, not cloud-based BIM.
Import a PDF floor plan or start on a blank sheet. Draw walls and rooms, define heating zones, route pipe circuits, place the manifold, and export a printable project report. A practical underfloor heating design workflow before you talk to your installer.
- Native macOS app (Sonoma 14.6+)
- Heating circuit layout with bend-radius checks
- Heat-loss overview and heat map PDF export

FAQ
Frequently asked questions — underfloor heating software for Mac
Is there underfloor heating software for Mac?
Yes. MyHeating Designer is a native macOS app (14.6+) for hydronic underfloor heating only. Download from the Mac App Store with a 3-day free trial.
Can I design underfloor heating myself?
The app supports pre-planning: floor plan, rooms, zones, pipe routing, manifold, heat-loss estimates and PDF export. It does not replace a certified DIN/EN design — have results reviewed by a professional.
Does it work with my PDF floor plan?
Yes. Import PDF, PNG or JPG, set scale from a known dimension, then draw walls and circuits on top. Or start from a blank scaled sheet.
How much does it cost?
Free download, full features for 72 hours. Then a one-time in-app purchase (Full Unlock). No subscription.
Do I need internet or an account?
No. Projects stay on your Mac. No login, no cloud sync, no in-app analytics.
