The Gradient All-Weather 120V Window Heat Pump, showcased at CES 2025, represents a significant advancement in window-based climate control. Unlike traditional window air conditioners that are limited to cooling, this innovative heat pump provides both heating and cooling capabilities, even in extreme temperatures. Its design, resembling a saddle with the indoor and outdoor units hanging below the window frame, maximizes window usage and offers a unique aesthetic. This setup allows for unobstructed views, easy window operation, and even utilizes the top surface of the indoor unit as a small table. The All-Weather model, specifically engineered to withstand harsh winters, can effectively heat a space even when outdoor temperatures plummet to -13°F (-25°C), a stark contrast to conventional window units that struggle in cold weather.
The Gradient heat pump boasts impressive performance specifications. Capable of conditioning spaces up to 500 square feet, it delivers 9,300 BTUs of cooling power and up to 9,000 BTUs for heating. A remarkable feature of this robust 140-pound unit is its ability to operate on a standard 120-volt outlet, eliminating the need for costly electrical modifications and professional installation. This plug-and-play capability simplifies the setup process significantly, making it a convenient solution for homeowners and renters alike. The unit also incorporates a misting system in the outdoor unit, which effectively dissipates condensate, preventing water accumulation and dripping. This thoughtful feature enhances the unit’s overall practicality and minimizes environmental impact.
Connectivity is another key aspect of the Gradient heat pump. Integrated Wi-Fi allows users to control the unit remotely through a dedicated app or via a touch thermostat located on the indoor unit. This smart functionality provides users with precise control over their indoor climate and allows for scheduling and automation features for optimal energy efficiency. Furthermore, the innovative design of the heat pump addresses a common drawback of traditional window units: the obstruction of natural light and ventilation. By hanging below the window frame, the Gradient unit preserves the functionality of the window, allowing users to open and close it freely, maintain their view, and enjoy natural ventilation when desired.
While the Gradient All-Weather 120V Window Heat Pump offers a compelling alternative to traditional HVAC systems, its availability remains somewhat limited. Initially focused on supplying units to the New York City Housing Authority, Gradient is gradually expanding its reach. Currently, business customers can purchase directly from Gradient, while a limited number of units have been made available to individual consumers through a specific contractor in the New York area. This strategic approach prioritizes scaling up electrification efforts by targeting larger entities like businesses, schools, and multifamily housing complexes.
The higher price point of the All-Weather model, with an MSRP of $3,800, reflects its advanced capabilities and robust performance compared to conventional window AC units. However, the absence of costly installation requirements, including permits, ductwork, and electrical work, significantly offsets the initial investment. This translates to lower overall installation costs compared to other heating and cooling solutions, making it a financially attractive option in the long run. The elimination of these additional expenses enhances the value proposition of the Gradient heat pump, making it a compelling choice for those seeking an efficient and cost-effective climate control solution.
In conclusion, the Gradient All-Weather 120V Window Heat Pump presents a compelling alternative to traditional HVAC systems, especially for smaller spaces and those seeking a simpler installation process. Its ability to provide both heating and cooling, even in extreme temperatures, combined with its innovative design and smart features, sets it apart from conventional window units. While the current availability is primarily focused on business customers and a limited consumer market, the potential for wider adoption is significant. The Gradient heat pump offers a promising glimpse into the future of home climate control, offering a more efficient, convenient, and environmentally friendly solution.
