Hewlett’s Orthodox Community Embraces Revolutionary Sabbath-Compatible HVAC Technology in 2025

In the heart of Nassau County’s Hewlett, a technological revolution is quietly transforming how Orthodox Jewish families maintain comfort during Sabbath observance. The Young Israel of Hewlett is a warm and welcoming Modern Orthodox Shul. Our membership ranges from absolute beginners to advanced observers. This diverse community, along with Chabad of Hewlett, a Jewish Center in Hewlett NY that provides Jewish and social programs for the local Jewish Community, and the Sephardic Congregation of Hewlett has emerged as a premiere Shul for Bukharian and other Sephardic Jews for families in Hewlett, NY, is leading the way in adopting cutting-edge climate control solutions that honor religious law while ensuring year-round comfort.

The Challenge of Sabbath-Compatible Climate Control

In Orthodox Judaism, using electrical devices on Shabbat is completely forbidden, as many believe that turning on an incandescent light bulb violates the Biblical prohibition against igniting a fire. This presents unique challenges for climate control systems. On that day and other Jewish holidays (Yom Tov), religious observers are restricted from doing “work that creates,” which includes operating electrical devices or creating new circuits.

Traditionally, Orthodox families have relied on workarounds such as timers on Shabbat, particularly for controlling lighting, heating, and cooling. However, They can use it, they just can’t turn the appliance on (or off) during Shabbos. This means families must either leave systems running continuously or endure uncomfortable temperatures during the 25-hour Sabbath period.

Modern Solutions for Ancient Traditions

The HVAC industry has responded to these needs with innovative Sabbath mode technologies. In 1998, Whirlpool’s KitchenAid line patented a “Sabbath mode”, and since then many manufacturers have followed by offering similar options. These modes typically turn off the electronic displays, disable oven and refrigerator lights that turn on automatically, and use delay timers that allow for permitted temperature controls.

According to recent research, “about half of all ovens and refrigerators on the market (including those made by GE, Whirlpool, and KitchenAid) now have a Sabbath mode.” However, HVAC systems present more complex challenges than kitchen appliances.

Breakthrough Technology in 2025

A groundbreaking development in 2025 has introduced “kosher electricity” systems that could revolutionize climate control for Orthodox communities. Developed through a study at the Beer-Sheva-based university and now being built in the city of Bnei Brak, the initiative uses energy storage systems to collect renewable electricity during the week and deliver it during the Sabbath in a way that complies with Jewish law.

The solution is a neighborhood-based energy storage system that collects and stores renewable energy — such as solar power — during the week, then distributes it to homes and buildings during the Sabbath without requiring any active human intervention. Operates as a micro-grid, the system that can serve entire neighborhoods, individual buildings, or even single apartments, offering a quiet, non-polluting alternative to private generators while aligning with religious laws and promoting environmental sustainability.

Practical Implementation for Hewlett Families

The installation of Sabbath-compatible HVAC systems requires careful consideration of several factors. In general, from an Orthodox perspective, it is permissible to benefit from most electrical objects during Shabbat, provided they are preset before the start of Shabbat, and the status of the appliance is not manually modified during Shabbat.

Modern systems can be programmed with sophisticated timers and sensors that maintain comfortable temperatures without requiring manual intervention. On Shabbat, it is generally permissible to adjust air conditioning vents as long as the adjustments are made manually and not through electronic means. This means physically manipulating the vents without utilizing any electronic controls.

The Future of Kosher Climate Control

The development of these technologies represents more than just technical innovation—it’s about preserving religious tradition while embracing modern comfort. Dr. Kalaji added that the project shows how religious tradition, community trust, and modern technology can work together. “This could be the start of new ways to bring innovation to all kinds of public services,” she said.

For Hewlett’s Orthodox families, these advances mean no longer having to choose between religious observance and comfortable living. To many people today, Shabbat represents disconnecting from the digital world to maintain a balance between technology and the sacred values such as rest, family, and spirituality—something the rest of us could very well benefit from.

As these technologies continue to evolve, Hewlett’s Orthodox community stands at the forefront of a movement that demonstrates how innovation can honor tradition while improving quality of life. With professional HVAC services from companies like Cool Bros Corp and cutting-edge kosher technology solutions, families can maintain their religious commitments while enjoying year-round comfort in their homes.
