Rellytech vs Nexaro Mini Splits Compared
Cooling Capacity
The Rellytech delivers 18,000 BTU of cooling power, making it suitable for larger spaces up to 1,250 square feet. This higher output allows it to handle bigger rooms like living areas or open-concept offices effectively. In contrast, the Nexaro provides 12,000 BTU of cooling capacity. This lower output is designed for smaller rooms, covering areas up to 750 square feet. If you need to cool a large space, the Rellytech has the advantage. For smaller bedrooms or dens, the Nexaro is sufficient. Choose based on your room size requirements.
Voltage Requirements
Electrical compatibility is a key decision point. The Rellytech requires a 208-230V circuit. This is standard for most dedicated mini-split installations but requires a specific breaker setup. The Nexaro offers a 115V option, which can plug into a standard household outlet. This makes the Nexaro easier to install in spaces without dedicated high-voltage circuits. However, Nexaro also offers a 230V version. If your home only has standard 115V outlets available, the Nexaro is the better choice. Otherwise, both units support 230V for optimal performance.
Energy Efficiency
Efficiency ratings impact your long-term energy costs. The Rellytech boasts a 19 SEER2 rating. This indicates good energy efficiency for its class. The Nexaro has a 17 SEER2 rating. While still efficient, it is lower than the Rellytech. Higher SEER2 ratings generally mean lower electricity usage for the same cooling output. The Rellytech also features an ECO mode to optimize energy use. The Nexaro uses inverter technology to adjust compressor speed, reducing power consumption. For maximum efficiency, the Rellytech holds the edge.
Indoor Unit Size
Physical dimensions affect where you can mount the indoor unit. The Rellytech indoor unit is 39.6 inches wide, 9.5 inches high, and weighs 112 pounds. It is a larger, heavier unit. The Nexaro indoor unit is 31.5 inches wide, 11.4 inches high, and weighs 68 pounds. The Nexaro is narrower and significantly lighter. This makes it easier to handle during installation and less obtrusive on the wall. If you have limited wall space or prefer a smaller profile, the Nexaro is the better fit.
Heating Performance
Both units are heat pumps, but their heating capacities differ. The Rellytech provides 18,400 BTU of heating power. This matches its cooling output, ensuring strong performance in cold weather. The Nexaro does not list a specific heating BTU figure in the provided data. Both units feature auto-defrost functions for cold weather operation. The Rellytech’s higher heating capacity makes it more effective for larger spaces or colder climates. If you rely heavily on heating, the Rellytech offers a clear advantage in output power.
