Della vs TOSOT Mini Split Specs
efficiency rating
The TOSOT model leads in energy efficiency with a 20.5 SEER2 rating. This higher number indicates better energy usage during cooling operations compared to standard units. The Della unit carries a 19 SEER2 rating. While still efficient, it falls slightly behind the TOSOT figure. Both units utilize inverter technology to adjust compressor speed. This helps maintain consistent temperatures. You will notice a difference in potential power savings. The TOSOT unit is designed to reduce electricity consumption more effectively. This makes it a stronger choice for those prioritizing low energy bills over raw cooling power.
cooling capacity
Capacity determines how much space a unit can effectively cool. The Della unit provides 18,000 BTU of cooling power. This allows it to handle larger rooms up to 1,000 square feet. The TOSOT unit offers 9,000 BTU. This capacity is suitable for smaller spaces or targeted cooling zones. You must match the BTU to your room size for optimal performance. The Della unit is clearly better for open areas or larger bedrooms. The TOSOT unit is ideal for smaller rooms or supplemental cooling. Choosing the wrong capacity leads to poor humidity control or excessive energy use.
smart control
Both units support Wi-Fi connectivity and Alexa voice control. The TOSOT unit adds specific app integration via the GREE+ application. This allows for detailed scheduling and remote management from your phone. The Della unit mentions Wi-Fi and Alexa support but does not list a dedicated manufacturer app in the provided data. You can control both units remotely. However, the TOSOT unit offers a more structured software experience through its branded app. This may provide more granular control over schedules and modes for tech-savvy users.
noise level
Quiet operation is critical for bedrooms and living spaces. The TOSOT unit operates between 22 dB and 36 dB. This range includes a very low minimum of 22 dB. The Della unit is rated at 29 dBa. This is also a quiet rating suitable for most indoor environments. The TOSOT unit has a slight edge in potential quietness with its lower minimum decibel level. Both units are designed to minimize disruption. You will find both acceptable for sleeping areas. The difference is minor, but the TOSOT unit offers a quieter baseline in its lowest setting.
indoor unit size
Physical dimensions affect where you can mount the indoor unit. The Della indoor unit is 37 inches wide, 12.4 inches high, and 8.82 inches long. It is a wide, low-profile unit. The TOSOT indoor unit is 23.2 inches wide, 31.1 inches high, and 14.7 inches long. It is taller and narrower. The Della unit requires a wider wall space but takes up less vertical height. The TOSOT unit fits better in spaces with limited width but more vertical clearance. You should measure your wall space before deciding. The form factor is completely different between the two brands.
