Question: may I use water heated in a "dud-shemesh" (solar water heater) on Shabbath?
It is forbidden to use water which was "cooked" on shabbat. So for instance, if one had a gas-flame water heater, it would not be permitted to use the hot water on shabbat.
However:
- A "dud-shemesh" heats the water by direct application of the sun's energy, and heating by direct solar energy is permitted.
- The cold water coming into the heating unit does not mix directly with the hot water, and so does not "cook" indirectly, which would be forbidden (actually, "patur aval assur").
Given this, it is permissible to use hot water from a solar water heater on shabbat.
See also the responsa of the Tsits Eliezer part 7, siman 19, who permits use of a dud-shemesh on shabbat in accordance with the ruling of R' Kapach.
שאלה: האם מותר להשתמש בשבת, במים שהוחמו בשבת ע"י דוד-שמש?
אסור להשתמש בחמין (מים חמים) שבושלו בשבת. למשל, אם יש דוד גז, המים שהוחמו שם בשבת אסורים לשימוש בשבת.
אבל:
- דוד-שמש מחמם אע"י פעולה ישירה של השמש, ומותר לבשל בחמה עצמה.
- המים הקרים שנכנסים לדוד, אינם מתמזגים ישירות עם המים החמים, ולכם אין כאן בישוך ע"י תולדות החמה, שהוא אסור אבל פטור.
בגין הללו, מותר להשתמש החמין שהוחמו ע"י דוד-שמש בשבת.
ראה גם תשובת ציץ אליעזר חלק ז סימן יט, שמתיר שימוש בדוד-שמש בשבת בהתאם לפסק הרב קפאח.
