These are rough estimates for similar-sized split AC / heat pump units (around 2.5–3.5 kW cooling capacity, common for these price points) in cooling mode, typical summer use. Costs assume roughly 4–6 hours of effective daily runtime in moderate conditions (inverter units cycle efficiently). Actual use depends on room size, insulation, the temperature difference and your settings.
Estimated Daily Running Cost Comparison (Cooling)
| Model | Price (incl. basic install) | Energy Class (typical) | SEER (approx.) | Est. Avg. Power Draw | Daily Cost (4 hrs) | Daily Cost (6 hrs) | Notes |
|---|---|---|---|---|---|---|---|
| Vivax 630 | 630€ | A++ | ~6.1–6.3 | ~0.55–0.6 kW | ~0.50–0.55€ | ~0.75–0.85€ | Budget-friendly, solid efficiency for the price. |
| Kosner 650 (no WiFi) | 650€ | A++/A+++ | ~6.8–6.9 | ~0.50–0.55 kW | ~0.45–0.50€ | ~0.65–0.75€ | Good value (Midea-based), strong efficiency. |
| Kosner 680 (with WiFi) | 680€ | A++/A+++ | ~6.8–6.9 | ~0.50–0.55 kW | ~0.45–0.50€ | ~0.65–0.75€ | Same as above, plus app control and scheduling. |
| Gaitsu WiFi | 720€ | A++ | ~6.5 | ~0.55 kW | ~0.50€ | ~0.75€ | Reliable inverter with WiFi. |
| LG | 860€ | A+++ / High | ~7.5–9+ | ~0.40–0.50 kW | ~0.35–0.45€ | ~0.55–0.65€ | Premium efficiency (Dual Inverter). |
| Panasonic / Mitsubishi | 1000€ | A+++ / Top | ~8–9+ | ~0.40–0.45 kW | ~0.35–0.40€ | ~0.55–0.60€ | Highest efficiency, best long-term savings. |

Key Insights
- Cheapest to run: Panasonic / Mitsubishi and LG — premium units pay back via lower bills over 5+ years.
- Best value: Kosner models offer strong efficiency at a lower upfront cost.
- Vivax / Gaitsu: Solid mid-tier options.
- Heating mode (winter): SCOP ratings are usually lower (4–5+), so costs are a little higher than cooling but still very efficient compared with electric resistance heaters.
- Annual estimate: For summer cooling (e.g. 90 days × 5 hrs/day average) a Kosner might cost ~€150–250/year, while a premium LG / Panasonic ~€100–180/year (varies widely).
Tips to minimise running costs
- Use a 24–26°C setpoint.
- Enable eco / inverter modes and WiFi scheduling.
- Good insulation and shading reduce runtime significantly.
- Inverter tech in all these models keeps consumption low once the room is cooled.
