Slash Energy Consumption Costs with Exhale Fans - CleanTechnica
The article from CleanTechnica highlights an innovative energy-efficient HVAC solution developed by Exhale Fans, led by CEO and Founder Richard Halsall. Exhale Fans has created a bladeless ceiling fan that uses a unique vortex effect to draw air from below and circulate it evenly in a 360-degree pattern throughout indoor spaces. Unlike traditional ceiling fans that push air straight down, this design provides a smooth, whisper-quiet breeze that reaches every corner of a room, enhancing comfort while reducing energy consumption. This technology is applicable across various environments including offices, hotels, airports, data centers, restaurants, schools, and homes, aiming to support year-round comfort with a modern, discreet aesthetic. The article also references a detailed discussion on CleanTech Talk, where Halsall elaborates on the fan’s design and benefits. Overall, Exhale Fans represents a promising advancement in HVAC efficiency, offering a quieter, more energy-saving alternative to conventional ceiling fans.

The article highlights the upcoming Heat Pump Water Heater (HPWH) Day on October 23, organized by the nonprofit Advanced Water Heating Initiative. This event, which extends throughout the week, aims to promote the adoption and awareness of heat pump water heaters, a highly efficient water heating technology. Activities include free educational sessions such as HPWH 101, livestreamed contractor training, and a virtual conference featuring 50 industry leaders. The 2023 theme, “Go Go HPWHs,” emphasizes the innovative features and benefits of these systems. To further encourage public engagement, two manufacturers, Ariston and Bosch, are donating a free heat pump water heater and installation each. Interested participants can enter the raffle by posting on any social media platform about why they want or appreciate HPWHs, tagging their posts with #HPWHDay by October 23. The article invites readers to join the celebration, participate in the events, and consider entering the giveaway to win a free HPWH, while also supporting CleanTechn

The article from CleanTechnica highlights that the $2,000 tax credit for heat pump water heaters (HPWHs) is set to expire in 90 days due to recent Republican legislation. This tax credit, which covers 30% of the installed cost of a HPWH, has been a significant incentive for homeowners to replace traditional water heaters with more energy-efficient and environmentally friendly heat pumps. With average installation costs around $4,700, the credit could reduce expenses by approximately $1,410, and it can be combined with additional local utility rebates to further lower costs. The article urges homeowners to act quickly to install HPWHs before the end of the year, noting that unlike solar panels, HPWH installations typically have shorter wait times and can be completed within three months. It also provides guidance on choosing models, recommending that those using contractors select familiar brands, while DIY installers often opt for Rheem or A. O. Smith models available at major retailers. The piece includes resources for finding

The article from CleanTechnica highlights the critical but often overlooked role of refrigerants in the efficiency, cost, and environmental impact of HVAC systems, including air conditioners and heat pumps. Refrigerants are essential chemical compounds that enable cooling and heating functions, yet many systems operate with improper refrigerant levels. A common issue is undercharging, where systems have less refrigerant than designed, sometimes by about 15 percent, which can occur even at installation due to improper adjustment for specific configurations like longer piping. This undercharging leads to reduced cooling performance and increased energy consumption. Over time, refrigerant leaks caused by aging equipment, corrosion, and vibrations further degrade system efficiency. Residential HVAC systems can lose 5–11 percent of their refrigerant annually, resulting in a significant drop in the coefficient of performance (COP). Even a 10 percent refrigerant loss can reduce system efficiency noticeably, increasing energy bills by $72–$144 during summer months. Larger losses above 20 percent cause steep performance declines and soaring

Quilt, a heat pump startup, has pioneered the use of over-the-air (OTA) software updates in residential HVAC systems, significantly enhancing the performance of its heat pumps without hardware changes. By integrating higher quality sensors—such as additional pressure sensors and more accurate temperature and current sensors—Quilt was able to collect detailed operational data that revealed untapped capacity in their units. This insight allowed the company to increase the maximum heating and cooling output from 20,500 and 19,700 BTUs per hour to 25,200 and 24,000 BTUs per hour, respectively, enabling the heat pumps to better handle extreme temperatures while maintaining efficiency. The OTA update involved both software and firmware improvements across the main processor and microcontrollers within the indoor and outdoor units. While the inclusion of advanced sensors and networking components added some cost to the bill of materials, Quilt’s leadership believes the benefits—such as continuous improvement, broader market applicability, and avoiding the need for new hardware models—far outweigh
