MyHeating Designer started from a concrete need: plan a hydronic underfloor heating system for a private house build — with traceable pipe lengths, sensible pipe spacing, and a first heat loss estimate, not just sketches on paper.
What was missing on the market
For Mac, there was practically no option in the “DIY price segment” for homeowners. Professional HVAC suites often cost around €200 per month — reasonable for firms that use them daily, but hard to justify for a one-off personal project.
Heavy one-time tools on other platforms can cost several hundred euros and are built for full 3D/BIM workflows — more than needed for a focused UFH layout.
In between, something was missing: native macOS software that stays on the floor plan, uses real formulas for planning guideline values, and remains usable for DIY users and small installers.
What MyHeating Designer is
- Hydronic UFH only — no radiators, no wall or ceiling heating.
- 2D planning on imported PDF/PNG/JPG or a blank sheet — no 3D BIM, no DWG/IFC import.
- Transparent physics for estimates (U·A·ΔT, cell model, Darcy-Weisbach as a planning hint) — visible in reports.
- Local on your Mac — no login, no cloud, no analytics.
- German and English user interface.
- Mac App Store: free download, 3-day full trial, then one-time purchase (Full Unlock).
What the app deliberately is not
MyHeating Designer does not replace a certified DIN/EN heat-loss calculation or manufacturer hydraulic guarantees. All values shown are planning estimates. Before ordering and installation, inputs and results should be reviewed by a qualified professional.
There is no automatic spiral/meander generation as the main feature — heating circuits are drawn manually and fully editable afterwards. That matches the goal: plan with control, not “the software designs everything”.
Who it is for
Homeowners preparing their UFH and handing a clear document to an installer, and small heating firms who want quick pre-planning on Mac — without a heavy all-in-one suite.
