18000 BTU Mini Split

An 18,000 BTU air conditioner can effectively cool a room of approximately 700 to 1,000 square feet. For larger spaces or areas with poor insulation, consider a 2-ton mini split or 36k BTU mini split for enhanced coverage.

For both the TL and Opitma (TP) series of Della's ductless mini split systems (18,000 BTU), a 20-amp breaker is required. This is specified for both models to ensure safe and proper operation.

Della's Opitma (TP) series 18,000 BTU mini split air conditioner requires 1350W for cooling and 1310W for heating, outperforming many small window ac units or mobile home ac unit setups in efficiency, making it more energy-efficient. Estimated monthly cost: Around $50-$60 for 8 hours of daily use at $0.15/kWh.

Versa (TL) series 18,000 BTU mini split air conditioner requires 1840W for cooling and 1730W for heating, with higher power consumption. Estimated monthly cost: Around $70-$80 for 8 hours of daily use at $0.15/kWh.

The Opitma (TP) series is the better choice for most users, especially compared to a multi head mini split or dual-zone mini split, due to its streamlined energy efficiency and quieter operation.

Energy Efficiency

The Opitma (TP) series is significantly more energy-efficient, consuming only 1350W for cooling and 1310W for heating. In comparison, the Versa (TL) series uses 1840W for cooling and 1730W for heating, resulting in higher power consumption and potentially higher energy bills.

Noise Levels

The Opitma (TP) series operates more quietly, with an indoor noise range of 31-48 dBA and an outdoor unit noise level of 52 dBA. The Versa (TL) series is slightly noisier, with an indoor range of 32-50 dBA and an outdoor noise level of 54 dBA.

Dimensions and Weight

The Versa (TL) series is more compact, with smaller dimensions and a lighter outdoor unit at 70.6 lbs. The Opitma (TP) series, while larger and heavier at 84.9 lbs, offers better energy efficiency which may outweigh the size consideration for most users.

Cooling Area and Moisture Removal

Both models are designed to cool areas up to 1,000 square feet and remove 4.6 pints (2.2 liters) of moisture per hour, making them equal in this regard.

Yes, Della's 18,000 BTU ductless mini split heat pump systems are designed to handle extreme temperatures, offering both cooling and heating versatility. The cooling function operates effectively in temperatures up to 122℉, while the heating function works reliably in temperatures as low as -4℉. This makes them a versatile choice for both hot summers and cold winters.

For Della's 1.5-ton mini splits (equivalent to an 18k BTU mini split), the amps drawn vary by model, similar to smaller 12k BTU mini split units:

• For the Opitma (TP) series, the cooling function draws 6.1 amps, and the heating function draws 5.9 amps.
• For the Versa (TL) series, the cooling function draws 8.2 amps, and the heating function draws 7.7 amps.

Yes, Della's 18,000 BTU mini split includes air filtration, a feature also found in single room ac units and larger 36k btu mini split systems, that helps maintain clean and fresh indoor air by capturing dust and particles. This ensures a healthier and more comfortable environment for your home.

Yes, an 18,000 BTU air conditioner, like the Opitma (TP) series, is quiet enough for bedrooms—similar to a 9000 BTU mini split air conditioner but with greater coverage. The indoor unit operates at a noise level of 31-48 dBA, which is comparable to a soft conversation or a quiet library, ensuring minimal disturbance. Other models may have slight differences in noise levels, but all are designed to operate quietly, making them suitable for spaces requiring a peaceful environment.

A 1.5-ton mini split air conditioner has 18,000 BTUs. This is a standard conversion, as 1-ton of cooling capacity equals 12,000 BTUs.
