De ervaringen op dit forum zijn vooral met de gen 2 Auer variant die geïntroduceerd is in 2018/2019. Ik heb AI gevraagd beide documenten te vergelijken. Als ik de AI analyse mag geloven is de gen 3 meer dan alleen een rebrand. Duidelijk is in ieder geval dat de warmtewisselaar is veranderd dus hardware technisch is het apparaat zeker herzien.
This comparison focuses exclusively on the differences between the
Auer/Dimplex Edel WATER/2 (v2) and the
Intuis Edel EAU /3 (v3).

2. Parts Differences
The internal architecture was updated for Version 3, resulting in new part numbers for nearly all critical electronic and refrigeration components.
| Component | Version 2 Part No. | Version 3 Part No. | Change Note |
| Main Electronic Board | B1244096 | B1242088 | New C3S board with Bus communication. |
| Wiring Loom (Complete) | B1244101 | B1242041 | Updated for new board and sensors. |
| Compressor | B1472888 | B1473073 | Optimized for lower 0.110kg charge. |
| Plate Heat Exchanger | B1472889 | B1473074 | Updated flow characteristics. |
| Upper Casing (Hood) | B1944445 | B1944510 | Rebranded with Intuis logo/styling. |
| Fan/Motor Assembly | B1472890 | N/A | Removed/Integrated differently in v3. |
| Temperature Sensor (Tank) | B1244090 | B1244124 | New resistance profile for v3 board. |
| Pressure Switch | B1472837 | B1473012 | Updated safety threshold. |
As a heat pump expert, looking at the two exploded diagrams side-by-side reveals a significant engineering shift. While the external dimensions are the same, the internal "thermodynamic heart" of the machine has been completely redesigned for Version 3.
Here are the primary hardware changes I observe:
1. The Heat Exchanger (Item 11) — Visual vs. Text Discrepancy
- v2 (Left): Item 11 is a Brazed Plate Heat Exchanger (Part B1472889). It is visually a rectangular block.
- v3 (Right): Item 11 is visually a Coaxial Coil, even though the Intuis v3 manual parts list (page 30) still labels it as a "Plated heat exchanger" (Part B1473074).
- Expert Analysis: This is a major hardware evolution. The move to a coiled/coaxial design is a reliability upgrade. Coils are far less likely to clog with sludge or scale from the underfloor heating circuit compared to the narrow channels of a plate exchanger.
2. Complete Removal of the Fan (Item 5)
- v2 (Left): Includes Item 5, an 80x80 internal cooling fan (Part B1244453).
- v3 (Right): Item 5 is entirely removed from the design and the parts list.
- Expert Analysis: This is the primary reason for the noise reduction (from 34 dB to 31 dB). By optimizing the thermodynamics, Intuis eliminated a mechanical failure point and a source of high-frequency vibration.
3. Evolution of the Flexible Hose (Item 31)
- v2 (Left): Item 31 is labeled "Braided flexible hose," but in the diagram, it is drawn as a rigid vertical support leg that appears to provide structural stability to the pump assembly.
- v3 (Right): Item 31 is now drawn as a true flexible braided hose (Part B1448251).
- Expert Analysis: In v2, the "hose" acted more like a rigid pipe. In v3, the use of a genuinely flexible loop helps decouple the vibration of the circulator pump from the rest of the chassis, further quietening the unit.
4. The Hydraulic Assembly (Items 13, 14, 15, 16)
- v2 (Left): The assembly is a "kit" of separate parts: a plastic connector (13), the circulator (14), a purger connection (15), and the purger (16).
- v3 (Right): While the item numbers remain the same, the physical casting of the manifold (where Item 30, the O-ring, sits) has been redesigned into a more compact, integrated block.
- Expert Analysis: The v3 hydraulic group is more "monobloc" in nature. This reduces the number of potential leak points and makes the top of the unit less cluttered for servicing.
5. Refrigerant Circuit Components (Item 10 & 24)
- v2 (Left): The Pressure Switch (Item 10) and Expansion Valve (Item 24) are positioned horizontally and tucked deep into the compressor compartment.
- v3 (Right): These components have been rotated to a vertical orientation.
- Expert Analysis: For R290 (Propane) systems, vertical orientation of the refrigeration accessories is best practice. it ensures better oil return to the compressor and prevents liquid refrigerant from "slugging" the pressure switch, which increases the lifespan of the electronics.
Summary Expert Verdict:
Version 2 was a "first-generation" Propane design that relied on standard industrial components (plate heat exchanger, rigid pipes).
Version 3 is a "refined" consumer appliance. By moving to a
coaxial heat exchanger and
flexible hoses, Intuis has addressed the two biggest complaints of the previous generation:
sensitivity to water quality and
transmitted vibration noise. The removal of the fan (Item 5) further confirms that v3 is engineered specifically for quiet indoor operation.
