How we recommend a model
The text below serves as the standard reference for this selection aid: the same logic used by the wizard. Handy if you (or an AI assistant) want to review the rules without going through the steps. More detailed version: selection aid.md · overview for AI: llms.txt.
Steps in the advice
- Surface area in m² (required); ceiling height in cm is optional but refines the volume recommendation.
- Supplemental heating in winter? If so: only ELEC-models (electric element next to the heat pump).
- Installation on a tiled roof/knee wall? Then different margins apply; vertical and ceiling models are excluded.
- Fits a horizontal model, otherwise MINI, otherwise vertical; Ceiling only as a fallback close to the ceiling when wall models do not fit.
- Within the appropriate form, we choose the smallest Model that still has sufficient capacity after the safety margin. Nothing fits: the largest suitable model, with the notification that one unit might be too small.
safety margins capacity
- Area: specified m² + 5 m²; for tiled roof/knee wall still + 10 m².
- Volume (if height is known): m² × height + 10 m³; for tiled roof/knee wall still + 25 m³.
Required space (including installation margins)
| Type | Appliance (approx.) | Standard clearance | Tighter (less headroom) |
|---|---|---|---|
| Horizontal | 55 × 101 cm | 80 × 105 cm | 65 × 105 cm |
| MINI 9HP | 55 × 81 cm | 80 × 85 cm | 65 × 85 cm |
| Vertical | 133 × 58 cm | 160 × 70 cm | 145 × 70 cm |
| Ceiling | 32 × 110 × 83 cm (HxWxD) | 35 × 115 cm |
Standard margins: approx. 20 cm at the top, 5 cm at the bottom, and 5 cm on each side. Ceiling weighs approx. 69 kg; two wall penetrations are still required.

| 12HP ELEC Ceiling | 3,05 kW | 3,00 kW + heater | 48m² | € 3.099 |
Preferred order of form
If multiple shapes fit: first horizontal (including MINI), then vertical, then Ceiling.
When no online advice
- Facade not free of obstacles (or doubt), while wall/ceiling mounting would fit.
- Tiled roof without a suitable knee wall or without a dormer where necessary.
- No shape fits the available wall or ceiling space.
