How each alternative compares
Della 27K BTU 3-Zone Mini Split
The Della 27K BTU 3-Zone Mini Split offers 24 SEER2 efficiency, which is higher than the 20 SEER2 rating of the original Della 28K model. This higher rating means you save more energy for the same cooling output. It uses a 9K+12K+12K zone split instead of three equal 12K units. You get precise control over rooms with different heat loads. It keeps Wi-Fi and Alexa connectivity for smart management. The outdoor unit is slightly heavier at 20.7 pounds. Choose this if you want top-tier efficiency and varied room sizes rather than uniform cooling power across all zones.
TOSOT 18,000 BTU WiFi Mini Split
The TOSOT 18,000 BTU WiFi Mini Split is a single-zone unit, unlike the three-zone setup of the original. It provides 20 SEER2 efficiency, matching the original's rating. This model is designed for one large room, not multiple spaces. It features Wi-Fi and Alexa control, just like the Della. The indoor unit is taller, measuring 37.3 inches in height. You lose the ability to control multiple rooms independently. Pick this alternative if you only need to cool one area and want a compact, efficient solution without the complexity of multi-zone distribution.
Della Vario 9000 BTU Mini Split
The Della Vario 9000 BTU Mini Split is a single-zone unit with 20 SEER2 efficiency. It is much smaller than the 28K original, targeting small rooms. It includes Wi-Fi and Alexa support for smart control. The indoor unit is only 11.5 inches high, similar to the original's height but much narrower. You give up multi-room coverage for a focused, budget-friendly option. This model is ideal if you only need to climate-control one small space. It offers the same smart features and efficiency rating but at a lower capacity and price point.
ROVSUN 28000 BTU Tri-Zone Mini Split
The ROVSUN 28000 BTU Tri-Zone Mini Split also provides 20 SEER2 efficiency and three zones. However, it splits capacity as 9K+9K+9K, whereas the original uses 12K+12K+12K. This means each ROVSUN indoor unit has less power. The outdoor unit is significantly heavier at 179 pounds. It supports Wi-Fi control but lacks Alexa compatibility in the provided data. Choose this if you need balanced cooling for three equal-sized small rooms. It offers the same total BTU output but distributes it differently, favoring uniformity over higher per-room capacity.
GrowthWing 18k BTU 230V Mini Split
The GrowthWing 18k BTU 230V Mini Split is a single-zone unit with 20 SEER2 efficiency. It covers up to 1,250 sq. ft., which is less than the original's 1,650 sq. ft. total coverage. It includes Wi-Fi and Alexa connectivity. The outdoor unit weighs 88 pounds, which is heavier than the original's implied weight. You lose multi-zone capability for a powerful single-room solution. This alternative is best if you need to cool one large space efficiently. It matches the original's efficiency rating and smart features but focuses on a single zone.
DELLA Vita 24K BTU 20 SEER2
The DELLA Vita 24K BTU 20 SEER2 is a single-zone unit, unlike the three-zone original. It offers 20 SEER2 efficiency, matching the original's rating. It supports Wi-Fi and Alexa for smart control. The indoor unit is 12.6 inches high, slightly taller than the original. You give up multi-room independence for a larger single-zone capacity. This model is suitable for large rooms where you need more power than a standard unit. It provides the same smart features and efficiency but consolidates everything into one zone for simpler operation.

Frequently asked questions
Which alternative offers the highest efficiency rating?
The Della 27K BTU 3-Zone Mini Split provides the highest efficiency at 24 SEER2. This exceeds the 20 SEER2 rating found in the original Della 28K model and most other options listed. Higher SEER2 ratings indicate better energy savings for your cooling needs.
Is there a multi-zone option with equal power distribution?
Yes, the ROVSUN 28000 BTU Tri-Zone Mini Split distributes power equally across all three zones. It uses a 9+9+9 BTU configuration, unlike the 12+12+12 or 9+12+12 setups found in other Della models. This makes it suitable for three rooms of similar size.
What is the smallest unit available for single rooms?
The Della Vario 9000 BTU Mini Split is the smallest option listed. It delivers 9,000 BTUs with 20 SEER2 efficiency and Wi-Fi control. This unit is designed for smaller spaces where high capacity is unnecessary but smart features remain important for your comfort.
Can I control these systems using voice assistants?
Most listed models support Wi-Fi and Alexa voice control. The Della 28K, 27K, 18K, 9K, and 24K units all include this feature. The ROVSUN model supports Wi-Fi but does not list Alexa compatibility in its specifications. Check the smart control attributes before purchasing.
Which unit covers the largest area in a single zone?
The GrowthWing 18k BTU Mini Split is rated for up to 1,250 square feet. While the Della Vita 24K BTU offers more raw cooling power, the GrowthWing model explicitly states this coverage area. It is designed for single-zone setups in standard bedrooms or living areas.
How heavy is the largest outdoor unit?
The ROVSUN 28000 BTU Tri-Zone outdoor unit weighs 179 pounds. This is significantly heavier than the Della models, which weigh between 20.7 and 26.5 pounds. You must ensure your installation location can support this weight when considering the ROVSUN alternative.
