Summary of "Darfst du deine Splitklima mit R290 selbst installieren?"
Overview
The video discusses whether homeowners can legally install split air conditioners themselves when the unit uses the natural refrigerant R290 (propane) instead of synthetic refrigerants like R32.
Main points and arguments
DIY installation and refrigerant regulations (F-Gas / climate rules)
- The speaker argues that, unlike synthetic refrigerants (e.g., R32, covered by F-Gas and related climate protection rules), R290 is not covered by the same refrigerant-handling certification requirements.
- As a result, they claim the refrigerant-related legal barrier that applies to R32 does not apply in the same way to R290, and you may not need a refrigerant handling certificate purely for the R290 component.
Why DIY may still be “blocked” in practice (electrical work is the issue)
- Even if R290 avoids refrigerant-certification requirements, a split AC is not plug-and-play.
- The units must be permanently wired into the home’s electrical system (e.g., junction/sub-distribution/main distribution).
- The speaker states that electrical installation is regulated (they reference “Section 13” of the Low-Voltage Connection Ordinance).
- They emphasize that most laypeople are not permitted to modify electrical systems, so DIY installation may still conflict with electrical-law requirements.
Conflicting online information
- The speaker notes that online sources are contradictory:
- Some manufacturers/shops warn against DIY due to fire/explosion risks and recommend professionals.
- Other websites claim DIY is outright forbidden and cite “the law” without clear details.
- The speaker says they are not aware of a specific law that directly regulates propane handling for DIY AC installation.
- Still, they reiterate that electrical rules likely create the practical legal limitation.
Safety and practical considerations (flammability)
Flammability risk of R290
- R290 (propane) is flammable and can form explosive mixtures in enclosed spaces.
- Typical split AC systems may contain roughly 300–400 g of R290—potentially enough to reach hazardous mixture conditions in small rooms.
Minimum room size requirement
- The speaker advises using the manufacturer’s data sheet to ensure a minimum room size that prevents formation of a flammable mixture.
- They give an example minimum around ~12 m².
Extra precautions
- Avoid smoking during installation/filling.
- Consider installing a gas detector at floor level, since propane is heavier than air and tends to sink.
- Note that R290 is “odorized” like propane in cylinders, but a detector still improves safety.
Comparison: R290 vs R32 (performance and climate impact)
Climate impact via GWP
The speaker contrasts Global Warming Potential (GWP) values:
- R410A: ~208
- R32: ~675 (as stated in the video)
- R290: ~3
They argue that leaks of R290 would be far less climate-damaging.
Efficiency / performance
- The video claims similar performance to R32, and sometimes slightly better performance depending on manufacturer.
Cost
- The speaker says R290 split systems are typically 50–100% more expensive than comparable R32 units.
- They attribute this to novelty and fewer manufacturers offering R290 systems.
Conclusion / takeaway
Legal takeaway
- Core claim: R290 may remove the F-Gas / refrigerant-certificate barrier.
- However, electrical connection rules likely prevent true DIY installation for most homeowners.
Market outlook
- The speaker predicts R32 will be phased out.
- Manufacturers will increasingly shift toward R290 due to future refrigerant bans (they reference timelines around 2030).
- They expect R290 to become more standard.
Safety outlook
- They believe leaks are unlikely in normal use.
- They argue the safety risk can be managed by:
- meeting minimum room-size requirements, and
- using a gas detector.
