Della vs Rellytech Mini Split Specs

Coverage area

Edge: Rellytech 18000 BTU 230V Mini Split

The Della Motto Series is rated for spaces up to 1,000 square feet. It uses R-32 refrigerant to maintain consistent temperatures in medium-sized rooms. The Rellytech model covers a larger area, rated for up to 1,250 square feet. This extra capacity makes the Rellytech better suited for open living areas or larger bedrooms. If you need to cool a wider space with a single unit, the Rellytech provides more coverage. The Della is sufficient for smaller zones but lacks the expansive range of the competitor.

Smart control

Edge: DELLA Motto 18k BTU 19 SEER2

The Della unit explicitly lists Wi-Fi and Alexa compatibility in its key specifications and features. You can control it via smart assistants and likely a dedicated app, though the app name is not specified. The Rellytech data does not mention any smart connectivity, Wi-Fi, or voice assistant support in its features or key specs. While some variations of the Rellytech line may include Wi-Fi, this specific 18,000 BTU model listing lacks those details. For users who want remote control via a phone or voice commands, the Della is the clear choice.

Indoor unit size

Edge: Tie

Physical dimensions matter for wall mounting and aesthetics. The Della indoor unit measures 37 inches in width and 12.4 inches in height. The Rellytech unit is wider at 39.6 inches but significantly shorter in height at 9.5 inches. The Rellytech also lists a weight of 112 pounds, while the Della weight is not provided. The Della is narrower, which may fit better in tighter spaces. The Rellytech is shorter, offering a lower profile that might be less obtrusive on a wall. Both are white, but their footprint differs.

Heating performance

Edge: Rellytech 18000 BTU 230V Mini Split

Both units function as heat pumps. The Rellytech data explicitly states a heating capacity of 18,400 BTU, which is slightly higher than its cooling output. This suggests efficient heat generation even in cold conditions. The Della data confirms it has a heat pump and can operate in temperatures as low as 5°F due to an upgraded bottom heating element. However, it does not list a specific heating BTU figure. The Rellytech provides more precise data on its heating strength, giving you a clearer expectation of performance in winter.

Airflow features

Edge: DELLA Motto 18k BTU 19 SEER2

The Della offers 4D airflow, allowing the louvers to move both up-down and left-right. This provides multi-directional air distribution throughout the room. It also includes an I feel mode, where the remote control senses the temperature rather than the indoor unit, allowing for personalized comfort settings. The Rellytech lists a 90-degree vertical swing and four fan speeds. It lacks mention of horizontal swing or remote sensing technology. The Della provides more advanced airflow control and precise temperature management features.

Which Mini Split Fits Your Needs

Users wanting smart remote temperature sensing

Our pick: DELLA Motto 18k BTU 19 SEER2

Those needing coverage for larger spaces

Our pick: Rellytech 18000 BTU 230V Mini Split

The Rellytech model is rated for areas up to 1,250 square feet, making it better suited for larger rooms or open floor plans.

Buyers prioritizing quiet operation and low temps

Our pick: DELLA Motto 18k BTU 19 SEER2

The Della system operates at a quiet 29 dBa, ensuring minimal noise disruption. It also includes an upgraded bottom heating element that allows efficient performance in temperatures as low as 5°F.
