Introduction to the EcoFlow Wave 3
The EcoFlow Wave 3 is a follow-up to the all-in-one battery-powered air conditioner, heater, and fan. This new model has dialed back its marketing hype and now offers a more powerful unit that can be recharged through several methods, including solar power. The Wave 3 can automatically maintain a set temperature range and act as a dedicated dehumidifier.
Key Features and Improvements
The third-generation portable heat pump from EcoFlow offers 6100BTU (1800W) of cooling and 6800BTU (2000W) of heating. While it can’t perform miracles, it’s suitable for small spaces like vans, surf shacks, work sheds, roof-top tents, boats, or other areas requiring occasional temperature control. The Wave 3 is designed to work in spaces up to 17 square meters (180 square feet), a significant improvement over its predecessor.
Testing the EcoFlow Wave 3
The Wave 3 was tested as a heater in a 14.8 square meter (161 square feet) tiny home and as an air conditioner in a 9 square meter (97 square feet) Class-B Sprinter van. The results showed that the Wave 3 could maintain temperatures inside the van at around 14C (57F) to 17C (63F) with outside temperatures ranging from 8C (46F) to 10C (50F). The device provided 13 hours of runtime off the optional 1024Wh LFP battery using a mix of Eco and Sleep modes.
Performance and Limitations
The Wave 3 performed well in shaded areas, bringing the internal temperature down to 16C (61F) and maintaining it. However, it struggled to cool the interior of the van when parked in direct sunlight, even with insulated sun reflectors installed. The device is also limited by its bulky intake and exhaust hoses and the space needed for a receptacle to collect drained water.
The Good and the Bad
The Good
- A heater, air conditioner, and dehumidifier in one portable device
- Optional battery that can recharge from 400W of solar
- Heat pump is super efficient
The Bad
- Limited to small, well-insulated spaces
- Most people will need more heating and cooling capacity
- Can get loud
- Pet Mode is not recommended
Dehumidifier and Other Features
The Wave 3’s dehumidifier works well and can be useful for preventing mold growth in RVs when parked in storage during the off-season. The device also has built-in Wi-Fi and Bluetooth, allowing for remote management through the excellent EcoFlow app.
Pricing and Conclusion
The EcoFlow Wave 3 is available for $849 without the battery, but most users would be better off with the Wave 3 plus battery combo, currently discounted to $1,399. The pricing is expected to increase to its full list price of $2,198 after May 25th. Overall, the Wave 3 is a niche product suitable for anyone who needs to occasionally heat or cool small spaces in temperate climates, especially if they’re located off the grid.
Conclusion
In conclusion, the EcoFlow Wave 3 is a significant improvement over its predecessor, offering more power and features while reducing marketing hype. While it has its limitations, it’s a great option for those who need a portable and efficient heating and cooling solution for small spaces. With its ability to recharge via solar power and its dehumidifier feature, the Wave 3 is a versatile device that can provide comfort and convenience in various situations.
