The Halachic Problem

It is well known that using the hot water tap in one's home or elsewhere on Shabbos is forbidden. As one removes hot water from the tank, cold water immediately rushes in and is cooked.

The AMNON18 Solution

AMNON18 is designed in such a way that you can use hot water on Shabbat & Yom Tov. Keeping the temperature of the water in the hot water tank below 'yad soledet', which is the minimum temperature required for cooking. Therefore, as one removes hot water, the cold water rushing into the tank is never halachically cooked but heated, even though it may reach the same temperature as the water that was already in the tank.

Key Halachic Points:

Temperature Control

Water temperature is maintained below 113°F (45°C), which is below the halachic threshold for cooking (yad soledet).

Halachic Compliance

Cold water entering the tank is heated, not cooked, making it permissible for Shabbat use according to Jewish law.

Rabbinic Approval

Endorsed by leading halachic authorities who have thoroughly reviewed the technology and its compliance.

Practical Application

Provides comfortable warm water for dishes, showers, and daily needs while maintaining full Shabbat observance.
