Della vs COSTWAY Mini Split Specs
Coverage area
Edge: COSTWAY 24000 BTU 230V Mini Split
The Della Vario 12K BTU is rated for up to 550 square feet. This capacity suits smaller rooms or open studio layouts where precise temperature control is needed without overcooling. The COSTWAY 24000 BTU model offers significantly higher output. While the exact square footage is not listed in the provided data, a 24,000 BTU unit typically serves larger spaces, such as two-car garages, large living areas, or commercial spaces. You should choose the Della for smaller zones and the COSTWAY if you need to condition a much larger volume of air. The higher BTU count on the COSTWAY ensures it can handle greater thermal loads in expansive rooms.
Energy efficiency
Edge: DELLA Vario 12K BTU 23 SEER2
Efficiency is critical for operating costs. The Della Vario 12K BTU achieves a 23 SEER2 rating. This high score indicates superior energy efficiency for its size class, meaning it uses less electricity to produce the same cooling output compared to lower-rated units. The COSTWAY 24000 BTU model is rated at 18.5 SEER2. While still efficient due to its inverter technology, the SEER2 score is lower than the Della’s. For smaller spaces where the Della’s capacity is sufficient, you will likely see better energy performance with the Della. If you need the raw power of the COSTWAY, you accept a lower efficiency rating relative to the Della’s compact design.
Smart control
Edge: DELLA Vario 12K BTU 23 SEER2
Control methods differ between the two units. The Della Vario explicitly supports voice control via Alexa. This allows you to adjust settings using smart home assistants, which is convenient for hands-free operation. The COSTWAY unit relies on a physical remote control with a display screen that turns off automatically after ten seconds to reduce light pollution at night. The COSTWAY features a smart timer ranging from 0.5 to 24 hours. While the Della also has a 24-hour timer, the explicit Alexa compatibility gives the Della an edge for users integrated into smart home ecosystems who prefer voice commands over physical remotes.
Comfort features
Edge: DELLA Vario 12K BTU 23 SEER2
Both units offer advanced comfort modes, but they approach personalization differently. The Della includes an I feel mode that senses room temperature at the remote control rather than the indoor unit. This allows for more accurate personal comfort control by adjusting airflow based on where you are sitting. The COSTWAY also features an IFEEL function and includes a turbo mode for rapid cooling. Additionally, the COSTWAY highlights a self-cleaning function that operates at high temperatures to clean the interior. The Della’s remote-sensing technology offers a unique advantage for precise temperature management, while the COSTWAY’s self-cleaning feature aids in maintenance.
Physical build
Edge: DELLA Vario 12K BTU 23 SEER2
The physical dimensions and weight vary significantly. The Della Vario is more compact, measuring 31.9 inches wide, 11.5 inches high, and 8.07 inches long, weighing 61 pounds. This smaller footprint makes it easier to fit in tighter wall spaces. The COSTWAY 24000 BTU unit is larger, measuring 44.5 inches wide, 13 inches high, and 9 inches long, weighing 68 pounds. Both units are white and wall-mounted. If you have limited wall space or prefer a less obtrusive indoor unit, the Della’s smaller dimensions are advantageous. The COSTWAY’s larger size accommodates its higher capacity components.
