You are looking for temprium 12000 btu 230v mini alternatives because your needs may differ from the original unit. The Temprium model delivers 20 SEER2 efficiency and quiet 28 dB operation for medium rooms. It requires a 230V circuit and covers up to 750 square feet. Some buyers prefer 115V compatibility for easier installation. Others might want higher SEER2 ratings or different smart features. The alternatives in this list were chosen because their specs overlap with the original product.
This guide compares 6 similar picks ranked by their published specifications. You will find options with 115V power, varying SEER2 ratings, and different control methods. Each product shares core traits like heating capability and inverter technology. We focus strictly on data such as voltage, coverage area, and noise levels. This approach helps you identify the best fit for your specific electrical setup and room size. Read on to see how these units compare in practice.
How each alternative compares
Rellytech 12000 BTU 20 SEER2 Mini Split
The Rellytech model runs on a standard 115V circuit instead of the 230V requirement of the Temprium unit. This makes it a practical choice if you cannot install new high-voltage wiring. It matches the Temprium with a 20 SEER2 rating and 12,000 BTU capacity for similar efficiency. You get Wi-Fi app control and heating modes just like the original. However, the Rellytech is heavier at 75.3 pounds compared to the Temprium’s 40.8 pounds. Its indoor unit is also wider at 31.9 inches versus 30 inches. If you need a plug-in solution rather than a hardwired one, this is the better fit. It covers the same 750 square feet of space.
Albott 12000 BTU 18 SEER2 Mini Split
The Albott unit operates on 230V power like the Temprium but offers a lower 18 SEER2 efficiency rating. This means it may use slightly more energy to cool the same 750 square feet. It includes both remote control and Wi-Fi app connectivity, matching the Temprium’s smart features. The Albott is significantly heavier at 151 pounds, which is nearly four times the Temprium’s 40.8 pounds. Its indoor unit is wider at 32.1 inches. You might choose this if you prioritize physical remote access alongside app control. The trade-off is reduced energy efficiency and much higher weight. It remains a solid 230V option for medium rooms where maximum SEER2 is not the primary concern.
YITAHOME 12000 BTU 115V Mini Split
The YITAHOME model runs on a 115V circuit, offering an easier installation path than the Temprium’s 230V requirement. It matches the Temprium with a 20 SEER2 rating and 12,000 BTU capacity. You get Wi-Fi app control and voice compatibility with Alexa, similar to the Temprium’s smart features. The YITAHOME is much lighter at 22 pounds compared to the Temprium’s 40.8 pounds. Its indoor unit is slightly narrower at 31.2 inches. The main difference is the voltage limitation. If you cannot support 230V wiring, this unit provides comparable efficiency and smart control. It covers the same 750 square feet. It is a lighter, easier-to-install alternative for standard household circuits.
COSTWAY 12000 BTU 20 SEER2 Mini Split
The COSTWAY Blast Pro supports 208-230V systems, aligning closely with the Temprium’s 230V requirement. It matches the Temprium with a 20 SEER2 rating and 12,000 BTU capacity. You get Wi-Fi app control and voice compatibility with Alexa, just like the Temprium. The COSTWAY is much lighter at 19.8 pounds compared to the Temprium’s 40.8 pounds. Its indoor unit is slightly wider at 31.9 inches. It covers the same 750 square feet. The key difference is the broader voltage support. If your home uses 208V or 230V, this unit offers similar efficiency and smart features. It is a lighter alternative that fits standard residential electrical systems without requiring specific 230V-only wiring.
Della Vario 9000 BTU Mini Split
The Della Vario model offers lower capacity at 9,000 BTU compared to the Temprium’s 12,000 BTU. It runs on 230V power like the Temprium and matches its 20 SEER2 efficiency rating. You get Wi-Fi app control and voice compatibility with Alexa. The Della is much lighter at 19.8 pounds compared to the Temprium’s 40.8 pounds. Its indoor unit is slightly wider at 31.9 inches. The reduced BTU means it is better suited for smaller rooms than the 750 square feet the Temprium covers. You might choose this if you need a more compact unit for a smaller space. It provides similar smart features and efficiency but with less cooling power. It is a lighter, smaller alternative for tighter areas.
ROVSUN 12000 BTU 230V Mini Split
The ROVSUN model runs on 230V power like the Temprium and matches its 20 SEER2 efficiency rating. It offers the same 12,000 BTU capacity for medium rooms. You get Wi-Fi app control similar to the Temprium’s smart features. The ROVSUN is significantly heavier at 70 pounds compared to the Temprium’s 40.8 pounds. Its indoor unit is slightly wider at 31.9 inches. It covers the same 750 square feet. The main difference is the substantial weight increase. You might choose this if you prefer a heavier, more robust build. It provides comparable efficiency and smart control but requires more effort during installation. It is a heavier alternative that maintains the same voltage and efficiency standards.

Frequently asked questions
Can I use a 115V mini split if I only have standard outlets?
Yes. The Rellytech and YITAHOME models operate on 115V circuits. This allows you to use standard household outlets without installing new high-voltage wiring. Both units provide 12,000 BTU cooling and heating for medium-sized rooms up to 750 square feet. They also include smart app controls for remote management.
Which alternative offers the quietest operation for a bedroom?
The Temprium 12000 BTU Mini Split is designed for quiet performance. It operates at just 28 dB. This low noise level makes it suitable for bedrooms or living areas where silence is important. It maintains 20 SEER2 efficiency while keeping sound levels minimal for comfortable overnight use.
Do these units support voice control with Alexa?
Yes. Several models integrate with Alexa for voice commands. The YITAHOME and COSTWAY units explicitly list Alexa compatibility. The Della Vario also supports voice control. This feature lets you adjust temperature or modes using smart speakers without needing to use the app or remote control.
Is there a model with a lower SEER rating but still efficient?
The Albott 12000 BTU Mini Split offers 18 SEER2 efficiency. This is slightly lower than the 20 SEER2 found in most other options on this list. It still provides solid performance for medium rooms. You get smart app control and quiet operation, though with marginally less energy efficiency than the top picks.
What is the difference between 208V and 230V units?
The COSTWAY Blast Pro supports both 208V and 230V electrical systems. This flexibility suits homes with different wiring standards. Most other units, like the Temprium and ROVSUN, require 230V. The COSTWAY model ensures compatibility if your home uses 208V, while still delivering 20 SEER2 efficiency and smart features.
Can I get a smaller unit for a tiny room?
Yes. The Della Vario is a 9,000 BTU Mini Split. It is smaller than the 12,000 BTU options. This makes it ideal for small rooms where less cooling capacity is needed. It still offers 20 SEER2 efficiency, 230V operation, and smart app control for convenient management of your climate.
Do these mini splits provide heating as well as cooling?
Yes. All listed units are heat pumps. They include heating operating modes alongside cooling. Whether you choose the 115V Rellytech or the 230V Albott, each model provides both functions. This dual capability allows you to maintain comfortable temperatures year-round using a single installed system for your home.
